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 :/

Finish my Raspberry Pi Zero Cluster... complete with kubernetes, etc.

... I still don't know what I'm going to run on this. suggestions in the comments welcome.

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)?

The 2014's called, they want their private server back!

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"

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.

So somehow midway through my class I got bored so I made Kubernetes-chan for no reason

My weekend project. Anyone else built a Raspberry Pi 3 cluster (for Kubernetes)?

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.

Rare footage of me waiting for my Kubernetes cluster to start.(2018BC,colorized)

Me: “I’ve done Kubernetes before what could possibly go wro-“

(cni0 breaks IPv4 routing serverside by containerd)

Me:

I was sleeping next to my wife and suddenly I raised my hand and shouted "gaaaa", when she asked what is wrong, I replied
"Kubernetes is misbehaving"
without waking up

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

Is it me or doing forty minutes standup meetings every morning is a complete waste of everyone's time? I don't need to explain what is Kubernetes and how to install it to my boss...

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 better

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.")

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.

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.

fren: do you have a date this valentines?

me: nah fam

fren: what u doin rn

me: [Insert technical explanation of Kubernetes here]

fren: [goes offline]

Job posting for Kubernetes with 5 years experience.
Kubernetes was released 4 years ago.

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? 😀

Just another normal conversation as a Kubernetes Operator

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.'

Is the technical term for a failed Kubernetes deployment a "clusterfuck"?

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

(And yes, I could've figured this all out beforehand with documentation, but this is more fun in my opinion)

[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" tho

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.

If you look closely, you can get an impression of the moment of "screw this, I'll look at it some other time".

I got 4 raspberry pi's with docker next to me. What's the best way to orchestrate them?
Kubernetes, docker swarm, other?

Kubernetes Note:
"Default" is not the default DNS policy.

OK!!!! (╯°□°）╯︵ ┻━┻

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.

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?!!!!

What is kubernetes, what is docker, and what is a container?

Today my professor permitted me to work with my seniors to set up kubernetes on our university's Nvidia DGX-1
😁😁 Happy AF

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,

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 ✌🏻

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 to

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 life

Here it goes my second Rpi cluster 😎
Actually there are 3 Orange Pi PC, 1 Rpi3, 1 Rpi2 and an Odroid XU4.
I plan on using it as a workbench for many technologies.
For example DevStack, Ansible, Gluster, TahoeLAFS, Kubernetes, Docker Swarm and such.
Any additional suggestions?

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 :D

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.

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 ?

I updated my online profiles to reflect that I am a certified kubernetes administrator, and the calls from recruiters wont stop.

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.

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

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?

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

I like the Kubernetes open source project. Big project that has been fairly good at smoothing things out and pushing the project forward.

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? ;--;

Just finished my Kubernetes book... This little piece of tech is amazing!!

Yay!! Kubernetes finally running time to learn the basics !!

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.

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.

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.

I am literally tasked with debugging why we have a 1.98 seconds lag on our site running on kubernetes. Smh

Debugging your application on a mesosphere cluster for the first time.

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*

Learn:

Docker, kubernetes, ceph, s3, and aws in general. Not really dev per se, but still worthy technical goals.

Installed centos 7, docker, standalone kubernetes on dev machine in 20 minutes.
Spend 8 hours starting fucking dashboard service, still no fucking luck, no fucking logs, nothing.
Fucking pending states without fucking explanation.
All the fucking pods are running fine except one fucking dashboard. I want to see the fucking dashboard.
Fucking shit fuck.
Probably as always if I clean the machine and reinstall everything it would start normally, without fucking problem.
Debugging fucking containers is so much pain in the ass, fuck.
I think it’s enough for today.

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!

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

Just got accepted to DigitalOcean's Kubernetes Limited Availability! Can't wait to test it out 😊

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?

I promised to blow off unit tests, so here we go. Let’s talk about unit tests.

Why use them? So, unit testing connoisseurs outline two big purposes:
1. To keep application integrity,
2. To catch bugs.

Keeping app integrity is when your freshly hired developer implement something that potentially leads to the whole app failure, but unit test fails and tell you that newly added code is breaking the app.

Catching bugs is pretty much self explanatory. Just think about it – you have to actually write code that describes how to check up another code to catch bugs in it.

I personally hate unit tests. I can’t explain, but every time I forced myself to write them, I got vertigo and terrible headache to the end of the day. Trying to write some tests? Here you go, wooosh and you can’t work anymore. Go get some sleep if you can.

But I still needed my job to be done and it should have been done really well. So I started my research.

Recalling Steve McConnell’s and many other classy developers’ experience, there is only one decent solution that prevents bugs and inconsistencies at large scale – the specs. Developing the specs should be considered the task number one. With decent, robust specs, app is almost guaranteed to contain no bugs.

Let’s take a look at the piece of great spec. For example, imagine you have to implement validation logic. So you state that validation should be implemented with special validation functions and then you define what validation function is: a pure function that accepts a value and returns boolean: true if value is good, false otherwise.

With that in mind, it’s obvious that potentially present bugs can only be inside that pure functions. Our spec made implementing validation very easy and idiomatic, isolating potential bugs. As soon as validators are pure and simple, unit tests aren’t needed at all.

You know what? As your app scales, you’ll definitely need a spec, sooner or later. Growing up without spec leads to irreversible failure, your app will grow like cancerous cell does and it’ll be easier to just put it into trash and start up from scratch.

But specs have one major downside – it requires at least one enlightened developer with really great experience to create it. It can’t be done quickly, it’s a very costly and difficult process. That’s why making great software costs that much.

But what if you need an MVP right now?

Speaking of MVPs, you’ll have to go with simplest instruments possible. Throw away Jenkins, use your Plesk autodeploy from Git repo. Throw away complex frontend setups, go with $30-$40 glittery ui kit or even an open source thing right from CDN, without less, sass, gulp and all that jazz. Make use of create-react-app if you can’t avoid using React because you’re making a web application.

Throw away AWS, Azure, Docker, Kubernetes and everything like that. Buy a cheap PHP7 hosting with pre-installed MySQL and do everything as simple as possible. If you have to use NoSQL, go with free Heroku with git autodeploy, NodeJS Express and free Mongo addon.

MVP should be ready in two weeks. As soon as your infrastructure is that simple, you don’t need unit tests. They’ll slow you down. Once you MVP is ready, go get funding, throw away first MVP, hire a decent CTO and let him create the spec.

Right there, it may be noticeable that unit tests are probably the biggest and baddest workaround imaginable. It gives you false sense of controlling your bugs, while you don’t have any control at all. Obvious bugs that unit tests can catch are easily noticeable at concise system, while quirky bugs couldn’t be caught by them because you can’t even imagine them while writing your unit tests. At this point, unit tests are just waste of time.

So, the whole picture is clear: at a small scale, you don’t have time to write unit tests and don’t have many bugs because of simple tools and standard patterns. At large scale, you need a spec to prevent bugs, unit tests become redundant as long as your spec is good.

In conclusion, I can tell that I’ve been developing a Clojurescript + CouchDB app for some startup, and in 8 month coding by spec I made myself I encountered only two or three bugs, all related to external JS tools and its quirks.

Have a good time!

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.

Trying to finally deploy the beta of a service I've been helping with, and of course everything possible is wanting to break.

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.

Finally set up my 5-node Raspberry Pi Kubernetes cluster.

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!

"shiny shiny" time... Lets standup a kubernetes cluster and then find a problem to solve! #BuzzWordDrivenDev

What is Kubernetes?

Sharded Deployments on Kubernetes

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

Fucking corporate business and their shitty installation instructions to fuck up peoples lives and switch them to the cloud.

Same was with fucking kubernetes

Fucking software dependency hell

It’s worse then ever before.

Fuck ....

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!

I'd like to Dockerize our Node.js webapp at work, though I've never worked with any form of containerization software. Has anyone got any good resources for learning it? Should I also be learning Kubernetes?

I'm getting sick of team leads and cto's who think you're wrong just because you're biased not the way they are or because you don't have any bias at all.

It goes like "Oh, you don't like Kubernetes? You're should be wrong because I think Kubernetes is the best thing ever done".

Ehhh
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 butter

Soo.. Not default?

You must've heard of recent unfamous CVE-2019-5736 vulnerability. This morning one of my hosting providers forcefully updated k8s version because of that. They also provide terraform module for k8s, which has "version" field required.

So during regular CI/CD process, TF decided it wants to recreate all existing clusters on that provider, basically wiping out everything there is.

No dataloss or operations disruption was registered, but a day was ruined. Guess nobody to blame except me.

That moment when you are so impressed about someone or something and interested and want to talk about it but you dont know how to even string two sentances about it even after you just spoke to someone that got you interested in it.

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 👌

When a CS student asks me (business IT student) how he can get kubernetes to work in PHP.
(No, I did not swap those two)
*facepalm*

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.

I fucking hate the Nginx Ingress Controller for Kubernetes. Fucking piece of shit. You fucking can't do a fucking simple rewrite and proxy pass???? Fucccck!

"This service runs outside of k8s so it can only be accessed from other services in prod"

Yay... Don't you love it when things can't be run outside of prod...

Should I be delighted or worried that I need to learn Kubernetes?

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.

Does anyone of you guys use Kubernetes? If yes, what setup do you have?

Hello, there is some good tutorial about kubernetes?

Thanks

spends almost 5 weeks trying to get CI/CD to work with Kubernetes (including installing Kubernetes itself).
Decides that he might go see if Nomad is a better thing for him...
Man, if only I discover stuff sooner...

Learn Scala, Akka, C#, Kubernetes, and improve my Python.

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 :/

Best book/source for learning everything devops'y'/kubernetes?

(Given that I have some sort of experience in Dockers, hosting websites and know a fracture of aws archeticture, but lack in good "cloud" thinking skills, scalability, understanding costs for production applications, cluster size, etc...)

Why is it so hard to setup and learn Kubernetes? :c

So I have a major deployment to do tomorrow. 8 repos. So 8 seperate deploys. Wish me luck.

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?

"Container design patterns" don't depend on containers

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.

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.

Learning to like manjaro, a lot, setting up i3 for a workstation and kubernetes cluster with a couple of manjaro workstations with just the cli installed... few gotchas on the way, get Hyper-V enhanced mode working but get a message session error on dbus launch - easy fix it is already launched by lightdm, the cli install doesn't start the network driver by default but can get a whole 3 node k8s cluster running in under an hour from scratch and forward i3 to a nice, fast, little windows x-server that I got for free with Microsoft reward points.. winning!

I'm all for the awesome stuff Microsoft is doing on the Azure stack, but it's laughable how their subscription management system on their portal is more complicated than spawning Kubernetes clusters and load balancers via terminal.

I mean c'mon!!!

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?

Started openshift to make send some of apps to cloud, damn it is too annoying. Everything is like 4x time consuming and hard, documentation really lacks, you google some errors? well answer is in red hat site and you can only see that if you are paid subscriber, issues in github are closed randomly(generally like we are going to fix this so no open issues??-written in 2017). If i had any other chance i would take it, like instantly.

I got these for under $2

Still working on setting up my Kubernetes cluster. Jesus Fuck this is complicated

+ Taste Dartlang and Flutter
+ Do something with WebXR and/or WebAssembly
+ Start some lil projects
+ Learn more about Kubernetes and monitoring services

*tries to build a Kubernetes cluster*
*gets error while trying to install Flannel*

crap...

AKS randomly fails preventing access to clusters. Is it just me or is AKS totally unreliable?!

Cloudfoundry Docker Diego Kubernetes. Loved working on the set. What about alternatives?

Hello guys,

is it good for every use-case to have a own ecs / kubernetes cluster?
It thinks yes, whats your opinion?
