Interviewer: Do you know what Kubernetes is?
Dev: Yeah, that’s the greek god of spending money in the cloud.
Interviewer: Actually Kubernetes is an orchestration tool. Have you not been on a project that uses it yet?

After our Head Of Software has terminated.
I started to take control over our development crew. And in this year I did more then the old head in the last 6 years.
- Swapped from plain old SVN to Gitlab.
- Build a complete autonomous deployment with Gitlab.
- Introduced code reviews.
- Started to refactor the legacy product with 500.000 lines of code...
- learned how to use confluent apache kafka and kubernetes to split the legacy project in many small and maintainable one.(not done yet)
- Last 3 weeks I learned how to use elasticstack with kibana and co. That we aren't blind anymore. Big dashboards are now shown in the middle of the room :) and maybe convinced my coworker that we use unity3d for our business application cause of support for all devices and same design on them. And offline capabilities. (Don't know if this was my best idea)
When I look back, I'm proud to did that much in one year alone. And my coworkers are happy too that they have less work with deployments and everything.
But I can't decide what's the title for this. System or Software Architect cause I litterallity did both :/7 -
How most recruiter emails go these days:
- Hiring multiple senior lead engineers <— That’s me
- 180k+ <— I like it.
- Must have experience with AWS, GCE, AND Azure <— Okay, you’re looking for a unicorn
- Kubernetes expert
- Experience with Rust, Node, and .NET <— What type of fucking company are you?
- Must be on call and 25% travel <— Why?
- Preferred: experience with printer repair, Raid Arrays, CAT5, and Microsoft Access <— Y’all fucked up somewhere a long time ago. I’m out.15 -
Finish my Raspberry Pi Zero Cluster... complete with kubernetes, etc.

As a full time remote employee it gets lonely. Im getting ready to turn my home into a co-working space :
* Plenty of space with tables and couches
* Gigabit Internet backed by enterprise networking gear
* Lots of fresh ground coffee
* Local Kubernetes server !
* dog friendly chill space
* kid friendly play areas during the summer
* Mountain home with backyard hiking trails , wildlife lookout (wild deer live in my back yard), and fireplaces
What else would you want in your co-work space-at-my-place (TM)?12 -
We've got a team of around 20 developers and the most junior of them all is a interesting specimen.
The kind of person who thinks they a 'expert' in anything and everything and is constantly trying to school our senior developers who have 20+ years experience behind them.
The sort of person that spends 15 seconds googling something he has never heard of before, but now that he has skimmed 1 page on Google would classify himself as a 'expert' in said topic.
He comes into my office yesterday and proclaims that it has been decided by himself that he no longer wants to be a developer anymore and wants to do Ops/Infrastructure, then starts rambling on about how he is a Kubernetes expert.
I asked what experience he had with Kubernetes and his response was "I watched a webinar they did last night" to which I asked if he had ever actually used anything to do with Kubernetes in his life.
"No, but I'll watch a few YouTube videos and will then be more than qualified" he says
Followed by him telling me that we'll be moving all of our current Docker Swarm clusters into Kubernetes.
This was news to me (I'm head of infrastructure and operations)
I needed a good giggle, so I asked why we would get rid of our exisiting Docker infrastructure that's got a 100% uptime over the past 2 years and has worked without failure. It's truely been a dream.
He says "Because it's shiny and cool and better"
The nest afternoon he comes to me and says "When I move everything into Kubernetes I am going to convert everything into micro services"
He says that he watched a YouTube video the night before on microservices and has decided that it's what we need to use for a particular project.
(It's a simple php website that gets 100 hits per day)
Hopefully his boss will notice that he is producing no output soon. Don't want to tell the manager that the guy he hired delivers no work and lives in a fantasy land.
"your not touching the infrastructure. Ever"15 -
I am trying to understand something for a while. devRant is full of privacy advocates and to be honest, part of it is almost taken by a group of people that call other people random swear words people because they are using a particular product of a company.
I will raise some points and will try to discuss them with other people in comments.
I will stick with Google. Since it looks like it's the most hated one. A company that has built one of the most intelligent infrastructure, the most popular mobile operating system and of course, the best search engine currently available.
The problem everyone sees is the privacy. Google tracks the search history to give users a better experience and show relevant ads. You might not need this "better experience". In case you don't know, you can turn off personalized search any time to make sure Google doesn't track. Same goes with Google Chrome, you can turn off all the data it is sending to servers in settings. You can simply not sign in if you don't anything to be synchronised.
An argument is Google should be opt-in rather than opt-out. But the general users are not tech-savvy. And yes, going to settings and turning on personalised search is a lot of work for a huge amount of people. Trust me, I worked in IT before. If they find other search engine giving them a good experience without changing anything in the settings, they will just simply move to that engine.
What interests me most if how people back DuckDuckGo. First of all, not all parts of DDG is not open source (it's fucking not, you can argue all day). Parts of it is closed because of licensing issues.
That is perfectly fine to privacy community. But it's not when Chrome is closed source for almost the same reason. I mean when you're using DDG, you are supporting a US-based company that has privacy all over its face and using closed source application on their server. Have you not learned anything from history?
You might be wondering about my obsession with Google. It hurts me when I see a giant company whose popular software is open source is bashed like this. Google has made huge contributions to open source communities. Chromium, Android, Kubernetes, Angular, GoLang, TensorFlow etc.
And PRISM, how do you know that DDG is not part of it? it's US-based after all.
I just saw an article that used a video with a title "TNW - Aral Balkan - Free Is A Lie | The Next Web" while asking us to switch to DDG. Ummm....DDG is also free right?
Maybe we should raise concerns with the US gov first rather than Google.60 -
--- URGENT: Major security flaw in Kubernetes: Update Kubernetes at all costs! ---
Detailed info: https://github.com/kubernetes/...
If you are running any unpatched versions of Kubernetes, you must update now. Anyone might be able to send commands directly to your backend through a forged network request, without even triggering a single line in the log, making their attack practically invisible!
If you are running a version of Kubernetes below 1.10... there is no help for you. Upgrade to a newer version, e.g. 1.12.3.

We are moving to kubernetes.
Nothing much has changed except we now get to say
it works on my cluster.
instead of
it work on my machine.1 -
You can believe or not but it’s just one of those stories. It’s long and crazy and it probably happened.
A few years ago I was interviewed by this big insurance company. They asked me on linkedin and were interested. They didn’t specify who they were so I didn’t specify who I am either.
After they revealed who they are I was just curious how they fuck they want to spend those billions of dollars they claimed in their press notes about this fucking digital transformation everyone is talking about. The numbers were big.
I got into 3 or 4 phone/skype interviews without technical questions and I was invited to see them by person.
I know that it would be funny because they didn’t asked me for CV so they didn’t know anything about me and I was just more curious how far I can get without revealing myself.
They canceled interview at midnight and I was in the middle of Louis de Funès comedies marathon so I didn’t sleep whole night. I assumed they would just reschedule but then they phoned me at 8 am if I can come because they made mistake.
So at first talk I was just interviewed by some manager I knowed after 5 minutes he would be shitty as fuck and demand stupid things in no time because he is not technical. He was trying to explain me that they got so great people and they do everything so fast.
From my experience speed and programming are not the things that match. ( for reference of my thought see three virtues of a GREAT programmer )
So I just pissed them off by asking what they would do with me when I finish this transformation thingy next year. ( Probably get rid off and fire at some point were my thoughts )
Then I got this technical interview on newest gold color MacBook pro - pair programming ( they were showing off how much money they have all the time ).
The person asked me to transform json and get some data in javascript .
Really that was the thing and I was so bored and tired that I just asked in what ES standard I can code.
The problem was despite he told me I can do anything and they are using newest standards ( yeah right ) the “for of” loop didn’t worked and he even didn’t know that syntax existed. So I explained him it’s the newest syntax pointing mozilla page and that he need to adjust his configuration. Because we didn’t have time for that I just did it using var an function by writing bunch of code.
When he was asking me if I want to write some tests probably because my code looked ugly as fuck ( I didn’t sleep for more then 24 hours at that point and wanted to live the building as fast as I can) I told I finished and there is no time for tests because it’s so simple and dumb task. The code worked.
After showing me how awesome their office is ( yeah please I work from home so I don’t care ) I got into the talk with VP of engineering and he was the only person who asked me where is my CV because he didn’t know what to talk about. I just laughed at him and told him that I got here just by talking how awesome I am so we can talk about whatever he wants.
After quick talk about 4 different problems where I introduced 4 different languages and bunch of libraries just because I can and I worked with those he was mine.
He told me about this awesome stack they’re building with kubernetes and micro services and the shitty future where they want to put IOT into peoples ass to sell them insurance and suddenly I got awake and started to want that job but behind that all awesomeness there was just .NET bridge with stack of mainframes running COBOL that they want to get rid off and move company to the cloud.
They needed mostly people who would dump code to different technology stack and get rid of old stack ( and probably those old people ) and I was bored again because I work more in r&d field where you sometimes need to think about something that don’t exist and be creative.
I asked him why it would take so much time so he explained me how they would do the transformation by consolidating bunch of companies and how much money they would make by probably firing people that don’t know about it to this day.
I didn’t met any person working permanently there but only consultants from corporations and people hired in some 3rd party company created by this mother company.
They didn’t responded with any decision after me wasting so much time and they asked me for interview for another position year after.
I just explained HR person how they treat people and I don’t want to work there for any money.
If You reached this point it is the end and if it was entertaining thank YOU I did my best.
Have a nice day.5 -

First time my laptop acted as a CV.
I've been in a personal project with my pal for like a three months. We meet sometimes at a cafe which is a very nice workplace, we often see more people with laptops, so we are not the only ones that thinks so.
My pal was waiting for me, he got a table early and then I arrived. there was a guy nearby us.
Me: (this guy has a newest new macbook pro, fucking riche)
-- I sit, put my laptop and start to work with my pal --
The guy starts looking at my stickers without hiding his doing at all. I noticed that instantly
Me: (Crap, he's gonna ask something :( )
-- I kept discussing stuff with my pal for like 5 minutes and then it happened. the guy stands up and... --
Guy: hey! how are you? sorry for bother, are you perhaps developers? I'm asking because I saw your stickers
Me: mmm yes
Guy: Do you have a job currently?
Me: We are in a project (No need to mention this is personal project and I got my full time job)
Guy: Oh, ok, no problem, you see I got a company, and currently we are looking for people to work with us, we want frontend developers with javascript skills preferable, but anything is welcome. Interviews starts next week, so if you are interested or know someone that could be, I'll give you my card and please write me at my mail if anything.
Me: got it, no problem.
-- I tried my best to hide my displeasure face(but I think I showed it a little), for him to being a riche with a new macbook pro, and you know, the interruption, I wanted to be focused while working in da project --
-- I got the card, I read it a bit, didn't dig into too much, there was stuff to do at the moment. the guy already returned to his chair and my friend --
Pal: Excuse me Mr Guy, what's the job tittle?
Me: (FUCK! dude!, we're working in our shit, don't give him more reason to try to scout us. we are behind the schedule and I need to explain this shit to you FFS)
Guy: Oh yes, will be frontend developer(again), but if you are a full stack that will be a plus too, we got some stuff with angular 1.x(ugh), and sencha touch(ugh) and ...(don't remember what else was it)
Pal: Ok and the job is full time in site? or are you open to work remotely
Me: (ok man, you sound interested, that makes me look interested too >:( )
Guy: preferable in site, but we would consider remotely depending on the person.
Pal: Good! thank you very much Mr. X
Guy: cool
-- Later on, like two hours, my friend goes to the counter for more coffee --
-- I text him: dude, I feel the guy will kidnap me or something --
-- then the guy start looking again at my laptop and... ---
Guy: hey! Jhon was your name right? Do you have experience with devops? I see your aws stickers
Me: yes
Guy: do you have experience with microservices?
Me: yes, a bit with lambda, also I've done some stuff with kubernetes, opsworks, rds and whatnot. no biggie
Guy: oh cool! we have a devops job too, there is a migration we need to do for an app to micro services. again if you are interested or know someone that it does. please mail me :)
Me: gotcha
There were no further interactions with Mr. Guy the rest of the day.
I'll be thrilled if someone ask me about my bee and puppycat sticker

Used to pay $5/mo on a small instance for my personal site. Then I discovered Kubernetes and realized my site didn't scale! No canary deployments! So I upgraded and pay $200/mo now. Took weeks to configure. Millions of people can now read my resume. Damn, it's never looked better8

Current work project is microservices architecture out of 4 - 8 components.
It is fully Infrastructure as a Code automatized. I just change somewhere code, git pushing
And it automatically invokes Gitlab CI, terraform, ansible, kubernetes helm charts.
Auto checking itself with unit and integration tests in autoredeployed staging env. Then it saves tested results to docker registry and asks for one button verificating click to be rereleased to prod.
I just go for drink or eat food. While all the stuff is happening.
And I am proud that all the infrastructure, backend and frontend I made on my own.
I don't need to remember how to Deploy it. It is all automatized3 -

Manager: "Can we get an accurate report on how many containers we have on the Kubernetes cluster?"
Me: "Well not really since Kubernetes is designed to be dynamic and agile with the number of resources and containers being created and deleted being subject to change at a moment's notice."
Manager: "I want numbers"
Me: "Okay well if we look at a simple moving average over time, we can see how the number of containers changes and then grab a rough answer from that"
Manager: "These numbers look a little round, are you sure these are exact?"

"Lockheed Martin Will Replace F-35's Faulty Computer System With Cloud-Based Programs"
WAT
So apparently those jets have such a fucked software that the recommended workaround is to use them offline and only reconnect them once every 30 days to keep the system running. It's so bad that two air force bases went back to an older system and the Israeli air force also replaced it for their own F-35 jets.
And somehow those stable geniuses think the correct solution is to make everything more network-dependent and apparently already put Kubernetes on a different line of jets.
I just can't stop laughing.12 -
Black Friday fail.
Local online store totally failed last year on BF, so they spent the whole week on news, radio, print ads, newsletter raving about how they upgraded the systems for BF and are expecting double the traffic of last year and are super ready. 60 seconds into BF, site went totally tits up, was not till 01:45 that anyone could access it again, and according to uptimerobot, they were tits up for about 55% of the day.

Since fucking when did "bare metal" mean just running on an OS?? At a conference and literally everyone is like "we got kubernetes running on bare metal", got super excited for a bit because just the idea of that sounds amazing but they're using it as slang for "basically not in a container or vm."
Nothing exciting at all. Now we're patting ourselves on the back for getting software working without it being preconfigured as a container or a VM image. No one knows how to do anything any more. MUCH too much abstraction going on.
I guess it keeps me more employable, but the state of the world from a developer standpoint is just sad.
(For reference, this is what the first sentence of "Bare Metal" looks like on wikipedia "In computer science, bare machine (or bare metal) refers to a computer executing instructions directly on logic hardware without an intervening operating system.")4 -

HR: you didn’t write in your job experience that you know kubernetes and we need people who know it.
Me: I wrote k8s
HR: What’s that ?
…
Do you know docker ?
Do you know what docker is ?
Do you use cloud ?
Can you read and write ?
Are you able to open the door with your left hand ?
What if we cut your hands and tell you to open the doors, how would you do that ?
What are your salary expectations?
Do you have questions, I can’t answer but I can forward them. Ask question, ask question, questions are important.
What is minimal wage you will agree to work ?
You wrote you worked with xy, are you comfortable with yx ?
We have fast hiring process consisting of 10 interviews, 5 coding assessments, 3 talks and finally you will meet the team and they will decide if you fit.
Why do you want to work … here ?
Why you want to work ?
How dare you want to work ?
Just find work, we’re happy you’re looking for it.
What databases you know ?
Do you know nosql databases ?
We need someone that knows a,b,c,d….x,y,z cause we use 1,2,3 … 9,10.
We need someone more senior in this technology cause we have more junior people.
Are you comfortable with big data?
We need someone who spoke on conference cause that’s how we validate that people can speak.
I see you haven’t used xy for a while ( have 5 years experience with xy ) we need someone who is more expert in xy.
How many years of experience you have in yz ??? (you need to guess how many we want cause we look for a fortune teller )

We have a long time developer that was fired last week. The customer decided that they did not want to be part of the new Microsoft Azure pattern. They didn't like being tied to a vendor that they had little control over; they were stuck in Windows monoliths for the last 20 years. They requested that we switch over to some open source tech with scalable patterns.
He got on the phone and told them that they were wrong to do it. "You are buying into a more expensive maintenance pattern!" "Microsoft gives the best pattern for sustaining a product!" "You need to follow their roadmap for long term success!" What a fanboy.
Now all of his work including his legacy stuff is dumped on me. I get to furiously build a solution based on scalable node containers for Kubernetes and some parts live in AWS Lambda. The customer is super happy with it so far and it deepened their resolve to avoid anything in the "Microsoft shop" pattern. But wow I'm drowning in work.24 -
So you want full stack engineers to: design, do UX, create front end, build backend and deploy it in your mono repo stupid manual deployment "kubernetes cluster", add monitoring alerting manually, review others PR, QA our own apps and features, manually sync to Production, use VPN otherwise we cannot connect to anything, 2factor auth, do SRE, architecture diagrams, demo, run agile ceremonies, and learn a legacy coding language which was never mentioned in the job description. Did I miss anything?7

To me, it seems like the rise of distributed systems like mesos / kubernetes combined with Docker require you to be master sysadmin, veteran kernel hacker and a part time c developer ALL AT ONCE if you really want to shave off time from debugging/ performance tuning sessions. Anyone wish they paid more attention in class ? Lol.

I work in a contract position and reviewed the code of a senior engineer recently. Regretfully I can't provide context to preserve anonymity.
He wrote awful JavaScript;
- handled a single DOM element with 2 different frontend libraries
- used the logical operator && to 'chain' two methods (it didn't work) instead of returning a boolean value,
- broke everything down into minute detail (a comment box had 7 components!),
- API calls were made for every component update instead of maintaining local component state where it made sense, which meant UI updates were slow,
- animated EVERYTHING, which made my Firefox on Xubuntu i7 64bit with 16GB RAM beg for mercy.
I had a rough couple of months with interviews, with 2nd stage technical interviewers throwing impossible tasks at me.
Example:
1. Create an online Python code editor with Javascript which can compile Python bytecode,
2. Use Mesos and Kafka to create real time architecture for Tensorflow with a Javascript frontend in 1 day. (I asked, and wasn't allowed to use Kubernetes or serverless architecture),
3. Hack a website from the browser's address bar using parameters ( what?!! ),
Obviously, the next time I meet a 'senior', I'm going to tell him talk is cheap;
'SHOW ME YOUR CODE.'3 -

Building a wheel is great.
Building a steering wheel is also great
Building a brakes pedal is amazing.
Making them work asynchronously - not that good of an idea is it...
Who the fuck thought separating data stream (copying bytes) from stream control (when does the stream start/end) is a good idea...?
- open a connection
- send data to the stream
- send() returns
- close the connection
Apparently, the send() does not copy the data and returns. Instead, it enqueues the data copying task end returns. When does the actual copying start? IDK. When does it end? IDK. Can I close the conn? NO!
This thing is UNUSABLE. And I'd riddle it with reflection-based workarounds if it weren't for the static methods.

So I was wondering, what is you guys' 'goal' in the long run? What do you really want to be able to do or what do you really want to achieve in 5 to 10 years? Are you working primarily for an income or are there more prominent reasons for doing what you do?
I'm in my last years of university and have a job at a software development company, not because I need the money but because of all the amazing technologies I come in touch with and the amazing things I learn, mostly about servers and devops tools.
I currently have 2 goals in mind: Creating an .io game together with a frontend developer and setting up a kubernetes cluster and using it. I personally consider kubernetes an end-game thing when it comes to running apps and am experimenting with it on three servers that I got from school.
So I was wondering, what ahout you? 😀27 -
A new head of operations joins a small company.
— Okay guys, I’m planning for the long run. I need 500 warehouses across the country — we might need that capacity. We will build them rather than renting them — Amazon does the same thing, so we should too. We also need our own shipping fleet — FedEx has that too, so it’s a battle-tested approach. We might need that capacity. We need a future-proof solution.
— Uh… That’s kind of dumb. Are you kidding me?
A new head of engineering joins a small company.
— Okay guys, I’m planning for the long run. I need an AWS cluster running Kubernetes deploying microservices built with Docker. We might need autoscaling. Frontend should be Next.js + TypeScript — everyone does that now, plus we can develop a React Native app more easily if need be. We need a future-proof solution.
— Wow! That’s what I call a good manager. You really know what you’re talking about. You’re promoted!4 -
School gave me 3 DigitalOcean droplets to try out Kubernetes in the cloud, awesome!
Wrote an Ansible script to not only simply install docker and add users but also add kubernetes, nice!
Oh wait, error?! Well I should've known this wasn't going to be easy... ah well no problem. Let's see... Ansible is cryptic as always, it can't connect to the API server? Is it even running?
Let's ssh to the master, ah nothing is running, great. Let's try out kubeadm init and see what happens, oh gosh, my Docker version has not been validated! No problem, let's just downgrade!
How do I do that? Oh I know, change the version in the role! Wait that version doesn't exit? Let's travel to Docker's website and see what versions exist of docker-ce, oh I see, it needs a subversion, no problem.
Oh that errors too? Wait then what... Oh I need a ~ and a ubuntu and a 0 somewhere, my mistake!
Let's run it again! Fails!
Same ssh process, oh wait...
Oh god no...
Kubernetes requires 2 cores and these things only have 1...
Welp, time to ask the teachers to resize my droplet by a small amount tomorrow, hopefully I'll get a new error!
----------------------------------------------
My adventure so far with Kubernetes. I'm not installing it for any serious/prod reason, just for educational purposes. K8s seems like 'endgame' to me, like one of the 'big guys' that big enterprises use so I'm eager to throw stuff at a droplet and see what happens.
Going further down the rabbit hole tomorrow!
Wish me luck :3

Inherited a simple marketplace website that matches job seekers and hospitals in healthcare. Typically, all you need for this sort of thing is a web server, a database with search
But the precious devs decided to go micro-services in a container and db per service fashion. They ended up with over 50 docker containers with 50ish databases. It was a nightmare to scale or maintain!
With 50 database for for a simple web application that clearly needs to share data, integration testing was impossible, data loss became common, very hard to pin down, debugging was a nightmare, and also dangerous to change a service’s schema as dependencies were all tangled up.
The obvious thing was to scale down the infrastructure, so we could scale up properly, in a resource driven manner, rather than following the trend.
We made plans, but the CTO seemed worried about yet another architectural changes, so he invested in more infrastructure services, kubernetes, zipkin, prometheus etc without any idea what problems those infra services would solve.2 -

I've kinda ghosted DevRant so here's an update:
VueJS is pretty good and I'm happy using it, but it seems I need to start with React soon to gain more business partnerships :( I'm down to learn React, but I'd rather jump into Typescript or stick with Vue.
Webpack is cool and I like it more than my previous Gulp implementation.
Docker has become much more usable in the last 2 years, but it's still garbage on Windows/Mac when running an application that runs on Symfony...without docker-sync. File interactions are just too slow for some of my enterprise apps. docker-sync was a life-saver.
I wish I had swapped ALL links to XHR requests long ago. This pseudo-SPA architecture that I've got now (still server-side rendered) is pretty good. It allows my server to do what servers do best, while eliminating the overhead of reloading CSS/JS on every request. I wrote an ES6 component for this: https://github.com/HTMLGuyLLC/... - Frankly, I could give a shit if you think it's dumb or hate it or think I'm dumb, but I'd love to hear any ideas for improving it (it's open source for a reason). I've been told my script is super helpful for people who have Shopify sites and can't change the backend. I use it to modernize older apps.
ContentBuilder.js has improved a ton in the last year and they're having a sale that ends today if you have a need for something like that, take a look: https://innovastudio.com/content-bu...
I bought and returned a 2019 Macbook pro with i9. I'll stick with my 2015 until we see what's in store for 2020. Apple has really stopped making great products ever since Jobs died, and I can't imagine that he was THAT important to the company. Any idiot on the street can you tell you several ways they could improve the latest models...for instance, how about feedback when you click buttons in the touchbar? How about a skinnier trackpad so your wrists aren't constantly on it? How about always-available audio and brightness buttons? How about better ports...How about a bezel-less screen? How about better arrow keys so you can easily click the up arrow without hitting shift all the time? How about a keyboard that doesn't suck? I did love touch ID though, and the laptop was much lighter.
The Logitech MX Master 3 mouse was just released. I love my 2s, so I just ordered it. We'll see how it is!
PHPStorm still hasn't fixed a couple things that are bothering me with the terminal: can't reorder tabs with drag and drop, tabs are saved but don't reconnect to the server so the title is wrong if you reopen a project and forget that the terminal tabs are from your last session and no longer connected. I've accidentally tried to run scripts locally that were meant for the server more than once...
I just found out this exists: https://caniuse.email/
I'm going to be looking into Kubernetes soon. I keep seeing the name (docker for mac, digitalocean) so I'm curious.
AWS S3 Glacier is still a bitch to work with in 2019...wtf? Having to setup a Python script with a bunch of dependencies in order to remove all items in a vault before you can delete it is dumb. It's like they said "how can we make it difficult for people to remove shit so we can keep charging them forever?". I finally removed almost 2TB of data, but my computer had to run that script for a day....so dumb...6 -
[Applies for RedHat OpenShift Beta on April]
this will be lit I said, since I was quite a bug reporter for Eclipse Che/Codenvy
[Took me until november to open up a ticket so they can take me in]
oooh shit this is lit
[Starts an Eclipse Che Workspace]
huh, why isn't it provisioning?
[inb4 OpenShift devs says its both a OSIO infra issue and a known bug in the OpenShift panel]
oof.
[Makes it work using workaround]
Woo this is gon-
[Haha no, Too Many tedirects for you]
REEEEEEEEEE
Conclusion: Openshift.io is a lit platform, it just happened to be very VERY beta.
I like the kubernetes "pods" tho3 -

I started to hate programming.
I started with a lot of enthusiasm 11 years ago up to become in 2 years a full stack dev, a sysadmin and had also my fair share of technical assistance on every device plus hardware experience mounting hardware like cctvs, routers, extenders, industrial printers and so on. At the time you actually had the tools to solve problems and had to crack your head and pull hairs to solve stuff and people actually was developing solution and frameworks that solved stuff.
Today I can't stand anything.
Every midschooler feels entitled to release a framework that is announed as the next cure for cancer. Web dev once was thin and simplistic, now simplicity is considered a bug and not a feature.
I'm working on an angular project for the nth time and the whole environment is a clusterfuck of problems held togheter with kids glue.
Someone did a tool/framework for everything but most of it is barely well tested or mature.
Just to start this project we had to know, beside html/css/js techs like Angular, Kafka, Kubernetes, Docker, git, Lit, npm/node, mysql/sql server, webpack/grunt and the hell that it brings, C#/Asp.NET/MVC/WebAPI, and so on, the list is long.
DAMN. Making a simple page which shows a tabbed view with some grids requires you to know a whole damn stack of technologies that need to cooperate togheter.
It's 10x more complex and I actually find it much less productive than ever.
But what bugs me most, is that 90% of that stuff is bug ridden, has some niche use case or hidden pitfall and stuff because with this whole crap of "hey we put on github you open a ticket" they just release spaghetti code and wait for people to do the debug for them.
Angular puts out a version every 2 days and create destructive updates.
I am so tired that I spend most of my 8hrs binging youtube vids in despair to procrastinate work.
I liked to do this once....13 -
I got 4 raspberry pi's with docker next to me. What's the best way to orchestrate them?
Kubernetes, docker swarm, other?19 -
Fuck, they updated the internal move policy in my company from 1 year 9 months to move to another team to be at least in the same team for 2 years.
I hope I can find a way to gtfo faster because I am honestly so tired of this shit, the tasks are getting too repetitive, my boss is useless, spends her time shopping instead of working and being stuck with a bunch of juniors means you only have the internet to learn something new.
I really want to start delving more into PAAS and start working with docker and kubernetes. Oh well, guess we'll have to wait and see.16 -
I finally bit the bullet and got a 2018 macbook pro i7 with 1 terabyte ssd. I've been needing a personal laptop for development for awhile. I thought about going full Linux but it's tough finding Linux laptops that support thunderbolt 3 charging.
I tried to make Windows and WLS work. But it's a pain getting my Golang, GCP, and Kubernetes workflow setup on it. I keep having to jump command prompts and it annoys the shit out of me. Going multi monitor helps a lot, but I like to be at coffee shops and code.
I feel sick a out giving Apple more money especially $3,000. But it was money well spent. My workflow is seamless and unlike on my Windows laptop I dont spend 3 to 4 days just setting up my environment.15 -
My productivity has gradually increased untill now by using:
Linux-server+VSCode (+Git+Terminal)+tmux+tmux-resurrect
Any further suggestion on dev tooling setup would be appreciated.
I primarily work on DevOps projects - bash scripts, linux server apps, containers, kubernetes,

I am back after 5 years
It's been a long time
After working for a shitty company, I ended up working for a startup for an interesting big project as a software architect
It was a good experience just for some stuff, but I hated every moment we needed to build some demo or prototype for potential customers or allies
I was tired... 2 years of demoing is too much. And finally I got a Senior Devops in this company working in Kubernetes
I finally discovered my role and my position, I want to solve problems for other devs and myself. I help anyway in the final product, because fast and reliable build and release cycle need to be a must
I wish everybody could find their main role. I took 12 years to find mine lol -
oh, I have a few mini-projects I'm proud of. Most of them are just handy utilities easing my BAU Dev/PerfEng/Ops life.
- bthread - multithreading for bash scripts: https://gitlab.com/netikras/bthread
- /dev/rant - a devRant client/device for Linux: https://gitlab.com/netikras/...
- JDBCUtil - a command-line utility to connect to any DB and run arbitrary queries using a JDBC driver: https://gitlab.com/netikras/...
- KubiCon - KuberneterInContainer - does what it says: runs kubernetes inside a container. Makes it super simple to define and extend k8s clusters in simple Dockerfiles: https://gitlab.com/netikras/KubICon
- ws2http - a stateful proxy server simplifying testing websockets - allows you to communicate with websockets using simple HTTP (think: curl, postman or even netcat (nc)): https://gitlab.com/netikras/ws2http -

By the time you get to need to learn Kubernetes, people are usually too far deep in their engineering careers and already have this 'not even more shit' fatigue.4

To those able to join us in the Netherlands:
So you want some devrant goodies? We are having a (IMO) cool event soon.
"Collab - Digital Agency meets Cloud Provider"
We will go into various topics regarding; automation, CI, cloud, experiences and maybe a few things about clusters / kubernetes.
Everyone is happy to join us for 2 talks, beers (and maybe pizza!).
Last but not least we are able to give a way various goodies including stuff from DevRant ;)
You can order the free tickets at https://eventbrite.co.uk/e/...
I hope to see some devrant people there and make sure to hit me up if you will attend!
ps. if you have question, just ask away!12 -
OH MY GOD, i cant believe this is my 25th day without a job... why!!!! not with all the kubernetes and node js and javascript that i know. lol. not to mention golang and python and all the networking stuff, dns, aws etc. lol where are all the recruiters when i need them?!!!!8

Don't use your senior software engineer title or years of experience as reasons in a debate or argument about software
My manager was asking me what steps needs to be done to perform a disaster recovery for our cluster( on production). I will be honest here, I have not maintained this type of cluster(kubernetes) in production before. However, I have enough understand of the system to answer my boss question. I basically told him there are A, B, C you have to do.
My senior developer jumped in and said "No you should do A,C, B because C is more critical than B. " I then replied to him: "I understand your point, I notice that too, but .." Before I can even finish my sentence, this dude has already rolled his eyes and interrupted me very loudly: "Have you worked with these systems on production before? I did". The asshole knows I haven't maintained Kubernetes on production yet of course.
I got super pissed at him and pretty much shouted back to him and my manager: "Just because I haven't worked on this system on production yet, does not mean my argument is wrong" .
I then dragged my managers, that asshole, and other engineers in a room and settle this out. In the end, people agreed with my steps over that asshole senior engineer dude because I gave them rational reasons.
The conclusion is: Your senior title is given by the company, It doesn't mean anything to me. Also, it doesn't make you more right than another person just because he has a "lower" title than you.1 -
It's dangerous to be curious. And have time to spare.
This morning I was in THAT state and decided to spin up kubernetes inside an... Alpine docker container.
The day has almost passed and I think I'll have enough tinkering left for the night.
yay........... I guess...7 -
Today was a SHIT day!
Working as ops for my customer, we are maintaining several tools in different environments. Today was the day my fucking Kubernetes Cluster made me rage quit, AGAIN!
We have a MongoDB running on Kubernetes with daily backups, the main node crashed due a full PVC on the cluster.
Full PVC => Pod doesn't start
Pod doesn't start => You can't get the live data
No live data? => Need Backup
Backup is in S3 => No Credentials
Got Backup from coworker
Restore Backup? => No connection to new MongoDB
3 FUCKING HOURS WASTED FOR NOTHING
Got it working at the end... Now we need to make an incident in the incident management software. Tbh that's the worst part.
And the team responsible for the cluster said monitoring wont be supported because it's unnecessary....3 -
Kubernetes is a breeze they said. Now I‘m sitting here for several hours trying to find out why my pods randomly fail to resolve domain names.
Coming along my adventure: broken systemd configs, systemd-resolved stub causing loops, broken k3s modules and finding out that busybox‘s nslookup is broken for versions greater than v1.28.4.
50 issues later, I figured out that the dude who setup the corporate network (where the machine in question is located) uses two nameservers: one to resolve the internal routes and one for all the external domains. Luckily, coredns randomly picks a nameserver for each request. Therefore, sometimes queries for external domains reach the nameserver dedicated to the internal network which then answers with NXDOMAIN.
I hate networking so so much...4 -
Man, making scripts for random shitty tasks is so god damn nice. Like pushing a new version in a repo. Throw together a script to find metadata and kubernetes files and identifies and update versions automatically, then commit, tag and push. Simple script, not even 100 lines of bash, but saves so many silly mistakes.16
-
Kubernetes is actually sick. I love learning about it and playing around with localized clusters. The only thing that sucks is I would never use this for anything while I'm still a CS student. And I probably won't ever use this if I'm not in Devops. *sigh*. fun to learn about, regardless.
-
Spent ten plus years professionally coding, used c, go , python, openwhisk ,docker, kubernetes and God know what else. Now I have to convince those team members who coded so far in their free time that write fucking clean code, avoid dependency on distributed and hard coded configuration, how to build a product
Fuck my life2 -
Developer vs non developer interview:
Non developer:
How well do you know excel ?
Developer:
How would you write spreadsheet app, what if it was cross platforms mobile application but also desktop app ?
Non developer:
Do you know how to use windows?
Developer:
Do you know kubernetes, distributed systems, lambdas, cloud services and how to deploy to server farm ?
Non developer:
You know how to use printer / fax and coffee machine ?
Developer:
Do you have experience in writing code for embedded devices ?
Non developer:
Do you know powerpoint ?
Developer:
How well do you know javascript / html / css, are you comfortable with writing backend node.js code or electron applications ?
React native and native apps maybe ?5 -
Have a spare server at work doing nothing. Think to myself "I'll play around with kubernetes".
Step 1: install openshift (there's ansible, should just work...right?)
...

It's been three days and I am haven't started paying around with kubernetes yet. *Sigh*3 -
Nothing beats beeing allowed to pick when i come in for work. Also today is pretty chill. Building is halv empty and i only have to write a lil documentation for kubernetes :D
-
Yesterday, I was perf testing my small app (my first NodeJS app). I thought I'd do a small, ghetto test: bash forloop with curl and payload to be saved.
My favorite is "for i in {0..100}; do ... ; done". I start firing these bad boys in separate tabs. Everything works fine. I check the DB... Saved results: 303.
I break into sweats. Do I have a race condition? Holy shit, is my DB layer unsafe? Fuck fuck fuck.
I fire the forloop only once. Saved results: 101. FUCK.
I run the for loop for 0..10. Saved results: 11. Huh?
I promptly realize 0..10 runs 11 times. I'm a dumbass.
/Me proceeds to deploy my code to a kubernetes lab instance with https://youtube.com/watch/... playing in the back of my mind.6 -
One good thing about working at a shitty place is you end up knowing what not to do by just pure pain.
I once consulted for a company who had the latest tech - kubernetes, bit bucket, you name it. But it didn't matter. The code was shit. It's not about the tech, it's always about the people that use the tech.5 -
For all the hate that Java gets, this *not rant* is to appreciate the Spring Boot/Cloud & Netty for without them I would not be half as productive as I am at my job.
Just to highlight a few of these life savers:
- Spring security: many features but I will just mention robust authorization out of the box
- Netflix Feign & Hystrix: easy circuit breaking & fallback pattern.
- Spring Data: consistent data access patterns & out of the box functionality regardless of the data source: eg relational & document dbs, redis etc with managed offerings integrations as well. The abstraction here is something to marvel at.
- Spring Boot Actuator: Out of the box health checks that check all integrations: Db, Redis, Mail,Disk, RabbitMQ etc which are crucial for Kubernetes readiness/liveness health checks.
- Spring Cloud Stream: Another abstraction for the messaging layer that decouples application logic from the binder ie could be kafka, rabbitmq etc
- SpringFox Swagger - Fantastic swagger documentation integration that allows always up to date API docs via annotations that can be converted to a swagger.yml if need be.
- Last but not least - Netty: Implementing secure non-blocking network applications is not trivial. This framework has made it easier for us to implement a protocol server on top of UDP using Java & all the support that comes with Spring.
For these & many more am grateful for Java & the big big community of devs that love & support it. -
Stupid pipeline bullshit.
Yeah i get it, it speeds up development/deployment time, but debugging this shit with secret variables/generated config and only viewable inside kubernetes after everything has been entered into the helm charts through Key Vaults in the pipeline just to see the docker image fail with "no such file found" or similar errors...
This means, a new commit, a new commit message, waiting for the docker build and push to finish, waiting for the release pipeline to trigger, a new helm chart release, waiting for kubernetes deployment and taking a look at the logs...
And another error which shouldn't happen.
Docker, fixes "it runs on my machine"
Kubernetes, fixes "it runs on my docker image"
Helm, fixes "it runs in my kubernetes cluster"
Why is this stuff always so unnecessarily hard to debug?!
I sure hope the devs appreciate my struggle with this... well guess what, they won't.
Anyways, weekend is near and my last day in this company is only four months away.2 -
Currently learning Kubernetes Cluster. Wow so much to learn.
Much easier to setup any app for a Cluster. Only building the Image takes time 🙄
Containers are the future ✌🏻6 -
Hey guys i wanna build a Pi-like Cluster to try out kunernetes locally and I would like some parts advice for the boards, casing, cooling, and the rack itself.
so far I have a Cisco E1200 Router I would use for the cluster for SSHing and connecting to3 -
Updated our rancher setup today and it just completely fucked the server, kubernetes stopped working, rancher stopped working. Guess who's going to install kubernetes manually next week? ;--;2

Is just me or being a developer has become a complete nightmare?
I mean, I never expected when I got into it to have a simple life in the first place, it's a fucking problems solving job.
But heck, I'm in the field from more than 12 years and something has definitely changed for the worse. Believe me I am just seeking for a general consensus not approval or anything, but it doesn't feel anything like 10 years ago.
I have worked with .NET mostly in all his sauces from aspx, wpf, up to today .NET 10 and C#13 and in the meanwhile it happened that I needed to do tech assistance, code in exoteric shit, use arduinos and raspberries, use perl, java, turn into full stack with databases, devops and shit.
Each year it's worse, the "developer" word gets more and more blurred word to say "the one who must know everything".
I'm asked to know docker, kubernetes, kafka, CI/CD and devop shit, web dev, to get ertifications, to learn how AI works to the level of learning again matht to do matrix interpolations, to get on data science, python, numpy, pandas, pytorch and shit, to know every OS, to know about networking because APIs now have to use rest, a single verb for every action, because if routers and new communication protocols break you have to know and figure out why.
Not to mention that marketing and sales guy shove up the big customers ass every new tecnology to make our work look like bling-a-ling top notch 1% developer stuff that always use latest bleeding edge technology and you're forced to learn new immature frameworks every 2 months or so (latest being various javascript/typescript diagramming libraries).
Every idiot feels entitled to puke out a new framework or supersets of existing languages. I lost count how many supersets css has that I had to peek and learn lol.
Every fucking simple software I did from scratch and designed by myself, web portals for big pharma were much simple than whatever PM i get assigned to are and guess what, I published it and fixed ofc some bugs, but most bugs are related to customer unstable datasets and well, I never had bugs after the first few weeks, except once every few months and nothing serious.
The fucking things they let me do now are hypercomplicated and I spend days fixing other people bugs and we get some hair pulling structural problems becuase they shove in all they can (mediator patterns are a must): kafka, docker, messagebus, whatever javascript clusterfuck they can, patchworks of html and css blurred out in layers of hierarchical scss or sass, slapped into angular (the most immature and crappy shit in js) that has all of his hidden ways to bury and hide DOM (ng-deep: anyone? :host anyone?).
And it's all like this. Whenever I put hands everyone wants to do his little frankeinstein experiment cooking togheter in a cauldron a shit ton of different stuff, overcomplicated patterns.
it's a challenge at shooting flies with bazookas.
I'm really tired of technology at all, not only for my jobs. This fucking trend is a plague spread everywhere and now, since everyone has to deal with it, everything is unstable.
In my daily usage of a smartphone app crashes a lot or have weird troubles, slowness, websites are pretending to be full blown app with this shitty SPA trend and are filled with bugs and incompatibilites.
Basically every tech tool we use is 100% more prone to bugs than 10 years ago.I'm really thinking to find a simple job like baker or shit and get an old phone that just can call and send SMS.
I need to get out of tech for a few years to get back my sanity.
This is not a problem-solving job anymore.
10 years ago I needed to study too but once I got the tools in my hands the job was fun, you got a magic wrench and sky was the limit.
Now you got to fucking learn a ton of bullshit everyday and it's not like you see a end on it, everyday people push out new unstable and bugged shit waiting for devs to be guinea pigs for them. You gotta learn a ton of stuff of which 3/4 will be useless/obsolete/broken and considered inefficient the next month.

one thing I don't get from Kubernetes
if a group of containers are called pods, and pods are containers, and containers in Kubernetes are also inside containers, therefore, its a clusterfuck of containers?1 -
I’m currently working with a devops team in the company to migrate our old ass jboss servers architecture to kubernetes.
They’ve been working in this for about a year now, and it was supposed to be delivered a few months back, no one knew what’s going on and last week they manage to have something to see at least.
I’ve never seen anything so bad in my short life as a developer, at the point that the main devops guy can’t even understand his own documentation to add ci/cd to a project.
It goes from trigger manually pipelines in multiple branches for configuration and secrets, a million unnecessary env variables to set, to docker images lacking almost all requisites necessary to run the apps.
You can clearly see the dude goes around internet copy pasting stuff without actually understanding what going on behind as every time you ask him for the guts of the architecture he changes the topic.
And the worst of all this, as my team is their counterpart on development we’ve fighting for weeks to make them understand that is impossible the proceed with this process with over 100 apps and 50+ developers.
Long story short, last two weeks I’ve been fixing the “dev ops” guy mess in terms of processes and documentation but I think this is gonna end really bad, not to sound cocky or anything but developers level is really low, add docker and k8s in top of that and you have a recipe for disaster.
Still enjoying as I have no fault there, and dude got busted.9 -
I'm currently planning to set myselv up with some vps/dedicated server's for a project. What i plan to do to secure these servers is.
*Use centos 7
* Setup Wireguard and join all of the servers +1 client (my pc) to that network
*Disable SSH Access from outside that VPN
*Only allow RSA Key login to the Servers
*Install Cockpit for monitoring
*Intall docker/kubernetes for the applications i plan to run
What do you guys think of that as a baseline? Im not sure if my lower powered VPS (VPS M SSD from Contabo) will work as Kubernetes Nodes, does anyone have experience with that?
In general these Servers will be used for my projects and other fooling around.
If you guys have other suggestions for Securing/monitoring or other software i could put on to have more control without eating up to much of the Servers power, let me know :D12 -

Please don't apply if you don't fulfill all of the requirements.4 -
Personal Opinion:
If you/your company's goal is to achieve micro-services, kubernetes or any new shiny technology, then you are thinking it wrong.
These tools are a means to an end. They should be a solution to an issue you are facing/will certainly face. They should not be your end goal.5 -
I'm frustrated with an abundance of different *Ops we're having right now. You can spell a random word followed by "Ops", and it's probably a thing. I get that Ops people in general are important but when there is stuff like GitOps, MLOps, FinOps, it gets confusing pretty damn fast. There's no value in all these titles besides "duh" usually, since Ops are just Ops in most situations. They kinda can slap a tracing tool or two on top of your code base but in general they just do Kubernetes (with whatever's hip like Jaeger, etc.) nowadays and that's it. Hell, even "DevOps Engineers", for a majority of cases you'll encounter, are basically just Ops with a misleading prefix since it's just a way people call them nowadays for whatever reason.3

Learn:
Docker, kubernetes, ceph, s3, and aws in general. Not really dev per se, but still worthy technical goals.1 -
RAAAAAAH fuck fuck fucking shit!!! Fuck jest Typescript "on the fly" compilation esModuleInterop typeroots, missing definitions jest ts-ignore and xtest everywhere, manual npm linking with different pkg mgrs & pub to a private registry, building docker images locally and doing tag management across git, docker & kubernetes then cross fingers that prod which has 0 common setup with local & test somehow works, open architecture "tickets" and wait months before they resolve, then repeat ad infinitum. How the fuck can I be productive when I need to be all over the place all the time and deal with these meta-code shenanigans. I just wanna code, damned3

So I just saw a post on Facebook about a "Serverless Function as a Service on Kubernetes". Could someone give me eye bleach please?
I really can't wait after Scoped Storage and how goddamn slow it is, to have a "glorified microservice" take 5 minutes to spin up a container, just to do something silly like printing a hello world. In the post it was apparently showing a QR code.. that's it. A fucking QR code, because remember it's just a function.
A whole fucking operating system that goes up and back down, just to run a goddamn fucking function!!!8 -
Isn't there something less of a clusterfuck than kubernetes.....
Yes it's a clusterfuck literally10 -
I updated my online profiles to reflect that I am a certified kubernetes administrator, and the calls from recruiters wont stop.
-
I don't understand wtf is happening today..
- in project A, terraform suddenly decided to stop working with kubernetes-related providers -- the CA cert mismatch error. I agree, it should be not working, because there are 2 kube-api severs behind an LB. But why now??? Why was it working for the last 2 months, until NOW????
- in project B, terraform suddenly decided to stop working _correctly_ with kubernetes-related providers -- it doesn't find resources randomly, even though they are available and I can see them via kubectl get. TF_LOG=DEBUG shows terraform sending correct requests to the kube-api, but the response is a 404. wtf... I see those resources present in another terminal window, only using kubectl. wtf....
- my PR in github was commented, I wanted to ask a question seconds later, and I'm getting a 502 from GH
wtf... I can't spot a pattern and that drives me freaking crazy.
Is this the Friday's curse...? IDK4 -
Doing a technical assessment. Slightly different stack than what I am used to!
- NGINX instead of Traefik
- Kubernetes instead of Docker Swarm
Just because the stack is different, anxiety / impostor syndrome is kicking in. I'm proud of myself for commanding my brain and body to execute:
While !done:
- google,
- find simplest straightforward tutorial

Dear boys and girls.
If you ever do this again and release this as a public library (even better - an official client of your solution, e.g. kuber-fucking-netes), I will get my way into dR's gateway servers, trace down your IP in nginx's logs, find your location, probably use some means to get your first and last name (you prolly have a domain registered under your IP anyways...), buy a ticket to your town, get to your home and wait for night to fall. Once it's dark and you're asleep, I'll make sure to leave a real nice, warm and extraordinarily smelly turd on your doorstep (I'll also make sure the process of manufacturing that gem is as noisy as it gets - you just have to bend the right way, and....).
Gents. If you really, REALLY want to make writes asynchronous, at least provide a way to either get a notification once the write is synchronized, or allow the user to handle the threads/executors himself!

Everyone rides on k8s today....
But in the end it's just like Docker Swarm and Compose combined.
I don't know if Google is playing Elon Musk anymore.2 -
This story is related to Docker containers.
Three years back when I heard about docker my first impression of docker was mini Virtual Machine. Then when you start your first container it’s no way to get out apart from pressing ctrl+d or leaving it like a screen. One of the most embarrassing thing with it was I tried really really hard to setup SSH on one of the container to log in there somehow. Then I understood how to use Dockerfiles and the command called `docker exec`
I thought Dockerfiles are the most amazing thing I have ever used for docker. But then I got introduced to docker-compose, and now it’s same with kubernetes
Now a days I read most of the document before doing hands-on on any new technology. -
Fucking Kubernetes tutorials on youtube. I still have no clue on why. I just get the how.
Fucking explain why we need it in the first place!19 -
Windows containers with Kubernetes on AWS and Azure are thing now.
What does that mean? Is it now possible to containerize system critical windows 3.1 legacy software from the 90ties (like the ticketing software at Airport Paris Orly) and orchestrate it in the cloud?
Do you know any use cases for Microsoft Windows in the cloud?2 -
How many sh*t days does it need to make me down?
3 ...
I hate my company, for making everything overcomplicated and annoying.... I have to discuss with 3 peoples for 3 days to getting some gitlab premium licenses (20$ per month for 10 licenses)... Why do you need it? Why we can't use the free version? Why Why Why... It's not enough to tell them it will save us much times and improves the quality of development.....
Also I wanted to ask if we can to Jaxb or another Dev Conference this year... Then I got the information that we have about 2000 Euro for 10 people for training.......... What should we do if everyone buys a book this budget is out .... f*ck company....
Second day, half of the day was taken for fixing the live db on the fly cause of a bad structure of tables... at least fixed some other inconsistence too... later the day fixed a freaking shitty bug with Spring Devtools and 2 Classloader to make the product that I'm presenting in 2 days running.
Today next shitty day with discussion that everything I did last half year (introducing Microservices, Kubernetes, Kafka and other DevOps things) could be maybe useless when the external company will say that they use another ecosystem -..- for their microservices...
Someone looking for a disappointed java developer? I just want to develop the best product ever... I'm happy with every area... Frontend, Backend, DevOps, Fullstack, Architect in some kinds depends on the wishes and technologies.1 -
At my previous company, we used tools from all over the place. We switched between tools at will. Sometimes, some team would decide to use some tool while the rest of the company would use something else. The worst part was that there was no Single-Sign-On (SSO) either. Everyone would need to have an account on all of these said tools. It was chaos.
I realized that being integrated into one environment (even though would have the cost of a vendor-lock-in) was the best option to have because in that case, we wouldn't have to deal with operational hurdles like having integration from one tool to another. They would just come baked-in with the whole environment. That's how GSuite (formerly Google Apps for Work), Atlassian and other players succeeded - they gave a complete suite of services / software that integrated well with each other. You could jump back and forth between services without having to bother about integration with other tools. They'd all be there wherever you wanted them to be. Even cloud providers so that opportunity and built on it - Amazon Web Services (AWS), Google Cloud Platform (GCP), Kubernetes (in itself).
Another example is a company that used Jira, Confluence and Hipchat but for some dumb reason used Gerrit for their code review / hosting. Eventually, they realized that managing the integration with the Atlassian tools was far more expensive than getting bitbucket and migrating completely into the Atlassian environment.
It's always the integration that matters. Everything else is secondary. -
I like the Kubernetes open source project. Big project that has been fairly good at smoothing things out and pushing the project forward.
-
why the fuck those images wouldn't load? they come corrupt from K8S, but they are fine if I run the container locally, like... wtf? is Ingress NGINX doing something to them or did I configure something wrong?!

Monday marks the beginning of a new month. In the new month, I turn a year older. As I steer further and further away from "youthfulness", I intend on starting a new chapter in my life.
Sunday 28th Feb is the last day I put any investment towards my "white-collar" professional career. Beginning March 1st, all my energy is going towards my entrepreneurial career instead.
This means that instead of learning that Huawei HCIA networking certification that I hate, I'm going to continue learning Docker (then Kubernetes) which I intend to use on my first product & the many more to come. Instead of studying the horrifyingly boring Data Science course, I'm instead going to put my energy behind understanding GCP & AWS, with the hopes of eventually getting certified.
Basically, I'm going to put all my energy into learning technologies that interest me AND have the potential to help me deliver on my entrepreneurial journey faster & better, rather than studying certifications which everyone believe will make me more employable.
Unfortunately, there aren't that many jobs going around & I'm currently under a year long internship with extremely smart graduates (a valedictorian included). The joke is we're earning $250 a month and have zero hope of getting employed anytime soon. I'm tired of going down this path.
I'm glad I got my degree in CS, now onto creating job opportunities for my fellow peers!
PS: Expect rants about my entrepreneurship challenges, and celebrations about my entrepreneurship wins!2 -

Everyone I tell this to, thinks it’s cutting edge, but I see it as a stitched together mess. Regardless:
A micro-service based application that stages machine learning tasks, and is meant to be deployed on 4+ machines. Running with two message queues at its heart and several workers, each worker configured to run optimally for either heavy cpu or gpu tasks.
The technology stack includes rabbitmq, Redis, Postgres, tensorflow, torch and the services are written in nodejs, lua and python. All packaged as a Kubernetes application.
Worked on this for 9 months now. I was the only constant on the project, and the architecture design has been basically re-engineered by myself. Since the last guy underestimated the ask.2 -
Give me a second to get my todo list.
- get a office/server room built
- setup a home kubernetes cluster
- create an open-source ActivityPub whatsapp clone
- unify existing ActivityPub implementations where an account on one can be used on others
- finish dockerssh
- create an irc bridge for signal messenger.
- find a way to fully provision linux workstations fully unattended2 -
Kubernetes question:
So far I've created two pods, mongo & Go
Exposed those pods using services
Their IP is 10.x.x.x and accessible from my machine only (virtual lan I'm guessing only known to host), but my machine's network ip is 192.x.x.x therefore, not accessible from outside world and to do so I need to put nginx in front to receive requests and route them internally.
Is there a way in kubernetes to make it work like nginx in terms of:
Kubernetes listen to port 80 (for example) route based on received url. As you know in enginx we define a server block with server domain_name.tld
Anything similar in kubernetes? I've cheked ingress-nginx controller, and also saw LoadBalancer but that requires a cloud provider.
If anyone can also give an example it would be great, so far examples I checked ended up screwing my setup and had to reset kubectl to get things back working18 -
Four steps of professional development:
1. Simple and bad
2. Complicated and bad
3. Complicated and good
4. Simple and good
At CSS and frontend in general, I'm easy four, straight up. At architecture, I'm perhaps two in devops/docker/kubernetes/other crap and three at DB design. At electrical engineering and embedded stuff, I'm 1, no questions asked.
What are your rankings?1 -
I mean. People love Docker and Kubernetes? Really? I mean, I agree it's good. I'm just wishing if people demanded for better and simple software and not complicated stuff. Idk

About two weeks ago, at my workplace, I learnt about Django deployment in Nginx server with Docker and Kubernetes on Google Cloud Console.1

I've been to 4 kubernetes related tech talks and they've all been the fucking same. No depth, no new cool things, no little tricks or demonstrations, just the plain old boring shit I've seen a thousand times.
I've worked with it and love it for big projects, but going to conventions to hear someone talk about it is completely meaningless. Perhaps it's because I only learn by doing.
And before anyone says 'then don\'t go', I usually go with either friends or a colleagues and want to show my face, and have some drinks and snacks.
This was my techtalk.3 -
I am literally tasked with debugging why we have a 1.98 seconds lag on our site running on kubernetes. Smh4

I hope it fucking work this time, kubernetes has been on my damn list since last summer, gave up on my 2Mbits internet so I took a scaleway server with 200mbits let's hope I get it to work this time!

Oh my.. I think I'm enjoying molesting kubernetes :)
A while ago I got pissed at k8s because with 1.24 they brought backward-incompatible changes, ruling my cluster broken. Then I thought to myself: "why not create a Docker image that would run kubernetes inside? Separate images for control plane, agent and client"
Took me a while, but I think tonight I've had a breakthrough (I love how linux works...)!! The control-plane is spinning up!! Running on containerd
Still needs some work and polishing, but hey! Ephemeral k8s installation with a single docker-run command sure sounds tempting!
P.S. Yes, I know there is `kind` and 'kinder', but I'm reluctant to install a separate tool that installs a set of tools for me. Kind of... too shady. Too many moving parts. Too deeply hidden parts I may have to fix. Having a dumb-simple Dockerfile gives me the openness, flexibility and simplicity I want. + I can always use it as a base image to add my customizations later on! Reinstalling a cluster would be a breeeeeeze6 -

Any devs out there worked building Golang microservices for a production environment?
I don’t have a specific question really. Just wondering who is out there on a similar path!
I’m building using Golang, Google Cloud, Docker, Kunernetes, and Terraform currently on a personal product bound for production!1 -
Rails, React, React-Native, Docker, Kubernetes, Openstack, Jenkins, AWS, Microservices, Realm, MongoDB, PostgresQL, GraphQL (list goes on...), and I'm not even done yet.
6 months was spent learning all of the above because I found a Rails-only monolith on Heroku unsettling. My first batch of containers was just deployed and I couldn't be happier. Love my job.3 -
Wow.. Kubernetes makes me high!!
VERY literally.
Today O dug into k8s from a devops/admin perspective. Soooo many figures at play! Tried my best to understand it all in one go.
Now I feel like I used to feel back in my student days after successfully finishing a whole bottle of wine.
Dizzy and happy as fuck! 😁 and want to puke a little
go k8s!3 -
I want to start contributing to open source projects but cant find something easy enough for me to start with yet interesting enough for me to want to work on.
How is Kubernetes and terraform listed in the good for beginners list on github... I see massive frameworks listed there and i have never felt so dumb..2 -
Took the dive and started learning kubernetes for the last 90 minutes or so. All I can say at this time... is... fuckin' hell m8!
It's some pretty damn cool tech and deconstructing the pieces to understand how to properly build on top of it has been interesting; to say the least.
but shit, man...
the amount of abstractions happening on top of docker/containerd are just asking for tons of problems hahaha. The last place I worked, we had a fair share of devs that either could not or would not bother with trying to understand docker and would constantly push code to the environments, shit would break, and then they'd come to my team and ask us to basically be human log parsers for them... how in the hell my last company is going to fare with trying to roll out kube is beyond me.
tl;dr - kubernetes has a buttload of moving targets and abstracts a metric-fuck-ton of stuff. Last company I worked for is gonna strugglepuff trying to use it. -

I've never been a big fan of the "Cloud hype".
Take today for example. What decent persistent storage options do I have for my EKS cluster?
- EBS -- does not support ReadWriteMany, meaning all the pods mounting that volume will have to be physically running on the same server. No HA, no HP. Bummer
- EFS -- expensive. On top of that, its performance is utter shit. Sure, I could buy more IOPS, but then again.. even more expensive.
S3 -- half-assed filesystem. Does not support O_APPEND, so basically any file modifications will have to be in a
`createFile(file+"_new", readAll(file) + new_data); removeFile(file); renameFile(file + "_new", file);`
way.
ON TOP of that, the s3 CSI has even more limitations, limiting my ability to cross-mount volumes across different applications (permission issues)
I'm running out of options. And this does not help my distrust in cloud infras...

Next week I'm beginning a paid intership in an sysadmin/infrastructure manager/bit of devops position. My tutor already told me he would give me things to learn alone so we could work together on stuff, and I can't wait for it to begin.
However, in the meantime I don't have a lot of things to do, so I would like to put this downtime to use and start reading stuff.
I already know I'll be doing a lot of Linux (that, I already master pretty well), and also some Active Directory, Kubernetes, and a bit of DevOps. Those are the main keywords he throwed at me during the interview.
What subject would you advice me to start learning in advance ? Do you have nice resources/books/videos on those matters ?
I would have asked to my tutor but right now he's on holidays and I don't intend to piss him off with job related questions.
On a side note : do you have any good and complete documentation or learning resource about SELinux ? I've had issues with it on my main rig for some months and can't find any good answer so I decided to learn it as best as I can and come up with an answer on my own. Since I intend to work in the field, I should what there's to know about it anyway.6 -
Bought fucking nvidia gpu to test speed of some fucking machine learning models that generate speech.
6 hours wasted already for installing fucking dependencies
cuda, fucking tensorflow gpu, bezel and other shit
Fucking resetting password to download deb with cudnn,
really ??????? fucking emails are not delivered to my fucking mailbox
After mass click of send email and multiple account ban and unban I figured out I should login to nvidia website and then allow access to fucking developer every time I want to log in there - fuck shit
Uninstalling everything now looking for fucking compatible versions between software.
10 years in this business still fucking installation of dependencies is most difficult part

Hey devRant!
University student here. I’m trying to learn how to build scalable applications. I figured what better way to learn, than to ask this community!
So, some questions:
1. What is a good stack for scalability
2. Regarding microservices, when and where should you use node, .net, and go
3. I hear much talk about docker and kubernetes... how would you use these concerning microservices
Thanks!7 -

Yes I've won a few coding contests. Yes I've emulated clusters using Docker and Kubernetes. Doesn't mean that I can simulate machine learning over network like taking knife out of butter2 -
Does anybody use raspberry pi as Kubernetes node? I kinda have an experience of my pis do not have enough memory with 1Gb. The system would run about 5 minutes, and each second more memory would be allocated. After that, every node shut itself down. Is there anything I can do about that?2

After upgrading to kubelet 1.24 kubernetes won't even start. Complains about an unrecognized flag "--network-plugin=cni". And stackoverflow has nothing to offer to work around it.

Now I have to learn all about something big, called dockershim.

Do any of you have any good resources at hand on good ways of managing Docker deploys? I don't want to use something as overkill as Kubernetes. In the end I want to be able to spin up the application on a $5 DigitalOcean droplet if need be.

Hello fellow ranters!
So I just switched companies ( free from hell...rants if wanted) and now I'm facing a ton of new things I never worked with. Honestly I'm a little bit scared and thus I want to prepare a bit for the new stuff ahead of me. ( I'm a junior developer with only 4 years professional experience )
What are good resources to get some knowledge in the following topics, so I wont look stupid on my first day at the new company?
Docker
Microservice
DevOps ( CI/CD, Kubernetes )
I know some basic stuff to describe what these words mean but no work experience at all for these. My old work was purely monolithic Java EE 😅
Resources should be in English or German.
Thanks for every help!! 🙇🏻♂️🙇🏻♂️6 -
It took me 48 hours ( not continuously) to fix a bug by going through a cluster fuck code of multiple modules. Tracing the error through 5 or 6 layers. And u dont get error logs right away. You need to recreate that error and see the logs on a kubernetes pod. Just to find out the bug was a duplicate.
Yes jokes are on me. I fucked up by not checking for duplicate. I steered right away on that shit dipped bug like a hungry/zombie hound. Fuck me. -
So being in ops, I have certifications in networking and Linux, and am currently working on my Certified Kubernetes Administrator exam.
I've been talking to a few "professional" (they have jobs) devs that I personally know, and with the exception of 1, it seems like version control, automation, networking, and server related tasks are beyond them.
As I want to get into the dev side of things (devops preferably), I feel somewhat overwhelmed at some of the requirements of the job, especially knowing that I cannot take too much of a pay hit as I have a family to support.
My question is this, based on real world experiences with hiring, how much weight do you think knowing your way around networks, cloud, virtualization, servers, and all of the other things ops does when it comes to getting your foot in the door for a dev job?
I've casually looked around, and it seems that getting the foot in from this side is almost impossible.2 -

FOMO on technology is very frustrating.
i have a few freelance and hobby projects i maintain. mostly small laravel websites, go apis, etc ..
i used to get a 24$/ month droplet from digital ocean that has 4vCPUs and 8GB RAM
it was nore than enough for everything i did.
but from time to time i get a few potential clients that want huge infrastructure work on kubernetes with monitoring stacks etc...
and i dont feel capable because i am not using this on the daily, i haven't managed a full platform with monitoring and everything on k8s.
sure u can practice on minikube but u wont get to be exposed to the tiny details that come when deploying actual websites and trying to setup workflows and all that. from managing secrets to grafana and loki and Prometheus and all those.
so i ended up getting a k8s cluster on DO, and im paying 100$ a month for it and moving everything to it.
but what i hate is im paying out of pocket, and everything just requires so much resources!!!!3 -

Anyone's got a CKA certificate (Certified Kubernetes Admin)? I'm considering taking the course and getting certified, but a quick search on the internet scared me a little. The course and exam aren't that bad, but the experience of the PSI browser the exam must be taken in apparently is awful: it's a lottery whether it'll work or not, even a passing precheck test does not guarantee anything. People are setting up separate OS installations just for the exam.
Others say that their laptops cannot be used for the exam because of dual-gpu (even on windows).
This sounds like a nightmare.
I'm on LinuxMint 20.3 and I'm actually considering a separate installation of clean ubuntu.

Auto-healing deployments are great until your deployment fails because it can't handle sending a large number of push notifications (triggered by a message on a pub/sub topic that starts being read from on startup)...so restarts, tries to send them again, fails, restarts, etc...and meanwhile a few tens of thousands of users are getting spammed by notifications 😱5

Time to spend a few hours getting the lingo down but in short, using python to make a FE to allow users to create a Hermes config file that will be used on Kubernetes to set up clusters of servers on aws to run their version of our platform. My mind is so rekt and i thank the Devops guys for this needed break from the FE where i normally reside. I love working with people that are not only good but enjoy what they do. They make me a better developer myself 👏
This is one of the many vast reasons i love what i do and having a place to share with more like-minded induviduals like yourself, im grateful.
Thabks for reading and hope you have or had a great day. Keep up the good work all and stay focused 👌 -

I guess these days I work with Golang, gRPC, and Kubernetes. I guess that's a dev stack. Or turning into one at the very least. The only thing that annoys me about this stack, is how different deployments for kubernetes are different for CSPs. The fact that setting up a kubernetes/Golang dev environment is take a lot of time and effort. And gRPC can be a pain in the ass to work with as well. Since it's fairly new in large scale enterprise use, finding best practices can be pretty hard, and everything is "feet in the fire" and "trial by error" when dealing with gRPC.
And Golang channels can get very hairy and complicated really really fast. As well as the context package in Golang. And Golang drama with package managers. I wish they would just settle on GoDeps or vgo and call it a day.
And for the love of God, ADD FUCKING GENERICS! Go code can be needlessly long and wordy. The alternative "struct function members" can be pretty clunky at times. -
Best book/source for learning everything devops'y'/kubernetes?

Questions around Openshift:
My company is actually triying to find out if Openshift is a thing out in the developers world. We are currently (finally) investing some money in container architectures. But are quite unsure if Openshift is a real thing out there. So my questions:
For how long are you building Openshift application PODs and why?
Or alternatively: Do you know a good source of up to date surveys around the container world, or do you know who can do good and usable surveys in that kind of area?2 -
A better half of the day wasted.
Why?
Because fabric8 k8s client probably has a bug, where it fails to deliver the last part of the exec() output. Or the whole output, if it's short enough.
brilliant... Aaaaaand we're going back to the official k8s client with ~10 parameters in their methods.
Fucking awesome. -
So I’m going through a CKAD course. There is a section about checking the status of our Pods or the application running in it through Readiness/Liveness Probes— they mostly use an HTTP test, but there is a TCP option as well. My question is, how will the TCP test work on HTTP/2 given that it does not have TCP (it rather uses QUIC)? Sorry if this is a dumb question.1

Any hardcore vim users out there? In need of help with tabs/panes. I tried some google-fu, but not much help.
I have a kubernetes helper, where I can run a command like :Vikube, and it'll open the result in a new tab. Is there any way I can open the result in a splitpane instead? I've found some ways, but not any good ways :/4 -
Dear Lord, please stop people from enforcing standards and bypassing them themselves.
Take kubernetes for example. Since v1.24 CRI has been announced as the standard, and kubernetes is shifting to live by it.
But it's not.
Yes, it's got the CRI spec defined and the unix://cri.sock used for that standardised communication. What nobody's telling you, is that that socket MUST be on the same runtime as the kube. I.e. you can't simply spin up a dockerd/containerd/cri-o server and share its CRI socket via CIFS/NFS/etc. Because kube-cp will assume that contained is running on the same host as cp and will try to access its services via localhost.
So effectively you feed the container via a socket to another machine, it spins up the container and that container tries to
- bind to your local machine's IP (not the one's the container is running on)
- access its dependencies via localhost:port, while they are actually running on your local machine (not the CRI host)
I HOPE this will change some day. And we'll have a clear cut between dependencies and dependents, separated by a single communications channel - a single unix socket. That'd be a solution I'd really enjoy working with. NOT the ip-port-connect-bind spaghetti we have now.4 -
DigitalOcean, really just because of the pricing. I will say though that kubernetes in Google cloud is much better than what DO offers, so if cost wasn't an issue I'd probably prefer it

hey there
recently I've been thinking about a good way to deploy mass amounts of containers on kubernetes, but before I just go with docker, I want to learn about some alternatives
what are some other container softwares you guys use?2 -
I just setup Jenkins locally for the first time to do some CI/CD for a project using docker. Then I upgraded the container to the latest version of Jenkins.
I am liking it so far but haven’t really setup anything significant yet.
Any of you ranters have experience with Jenkins?
- would you recommend it. Pros/cons?
- what resources did you use to setup and expand your pipelines?
- any experience with Google Cloud Platform and Jenkins.
These are kind of open ended questions to start a discussion on the topic.
Jenkins will be used at least for deploying the front end built in React. I may also use it for deployment if the Golang API but that uses Kubernetes at the moment. -
Anybody uses DigitalOcean Kubernetes? Having some issues with certificates expiring, and can't access the nodes :/1
-
I’ve been assigned a Kubernetes task and I must say I really hate this shite. I’d rather code than be doing this 😑😶😑2

Any ideas how to skill up devops ? Currently in company im doing simple things with kubernetes, aws, terraform and circleci, and the whole idea click to create your inba cluster is interesting, smells like a few steps from cybersecurity!
Soo i decided to write an app, with two environments, which are staging and prod, configure some ci pipeline, kubernetes deployments and terraform, everything with usage of aws, and then when i will be okay with it, send cv's as devops and change career path.
Seems legit or waste of time ?2 -
So I was very bored this week and deceided to get my head wrapped around Kubernetes and the hype around it. After trying to get a cluster run on my old contano servers I almost lose my nerve and just went for DigitalOcean. Holy shit I am impressed by the service. 30 seconds TTL DNS, hourly rate billing and spinning a scaleable cluster in only minutes. I fell in love1

Anybody had experience with Hashicorp Nomad for smaller deployments (personal in this case)? Thinking of using it after having done it too many times with complex Kubernetes and Docker... 😅 Also don't wanna run this thing bare bones as i have a whole bunch of services to deploy together.

Hi guys! Last time you gave me a lot of good advice about my gophers. Thanks! Kubernetes Contributor Celebration is coming soon so I have these cute gophers
If you liked it and want to support me on Redbubble

or TeePublic https://teepublic.com/user/...
Thanks!

Spent two hours trying to work out why a Kubernetes pod wouldn't apply it's database migration when it works in every other environment. Turns out the database instance was powered off. Piss biscuits.

+ Taste Dartlang and Flutter
+ Do something with WebXR and/or WebAssembly
+ Start some lil projects
+ Learn more about Kubernetes and monitoring services -
Anyone know of any companies/agencies that are looking for freelance technical writers, for blog posts and such?
Mainly within the areas of DevOps, CI/CD, Kubernetes, bash etc. -
Has anyone here used app academy open. Is it good and does it teach useful and up to date stuff? I was thinking of doing it but there are barely any reviews online. There is a reddit thread about why it is handicapped but it is old and a user clarified it was misinformation. https://reddit.com/r/...
Their curriculum seems to be pretty good except that I will need to learn ruby on rails which I need to forget after the MERN stack part and that they teach docker compose instead of kubernetes -
I want to take my Certified Kubernetes Admin exam, but need to brush up on the exam material. Other than the Linux Foundation, what's the best place to learn this material from?1

Does a basic Kubernetes ClusterIP Service run on OSI Layer 4? There's musings of calling a Service Mesh 4.5, but out-of-the-box Kubernetes services... What OSI layer would you put them on?9

k8s is so good orchestrating its shit, yet it can't handle a node rolling update with deployments having one replica and a PDB of unavailable=0,
Dude... make a gooddamn exception, surge a damn pod for draining the node. -
I started a side project recently:
Open Source 2D MMORPG with K8s in Azure (AKS) and Unity:

Ok. Wtf?!?
Our platform architect gives a damn about continuous delivery.
Today I asked the architects for help, because bamboo is not able to trigger a deployment plan by changes in repository branch pattern release/x.x.x.
He cancelled my question with the statement "if we have the Kubernetes environment, we have more valuable things to work on".
Generally CD is no rocket-science and it is achievable with reasonable effort! -
Thanks vscode devs for the feature where they automatically map the local ports to remote port that are needed to run the node based application and also to the devs those who write such a great extensions (remote development, gitlens, docker and kubernetes)
No more ng serve -host 0.0.0.0
No more remote_ip:4200 in browser.
These two steps were so much frustrating whole pulling or checking out another branch.
I just need to learn how to run maven from vscode where I have to add another project in dependency.(never worked on maven before and hate long nested xml). AFTER that never booting vm in GUI.4 -
Whyyyy whyyy can a billion dollar company be the last regarding Kubernetes as a service!! EKS has such a fat ass, damn slow to bootstrap and a pain to manage the lifecycle, while all other clouds even the small ones have figured it out. Can't just get it.6

I have two coworkers that discuss every day for hours about anything.
Past month they were discussing about Docker Swarm x Kubernetes and it’s impossible to work without headphones and loud music.
