Like one of those jobs that demand 12 years of experience with Kubernetes (which was released 6 years ago)

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.

Saw this on LinkedIn

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

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.

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.

Yours truly #stolen

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

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

(cni0 breaks IPv4 routing serverside by containerd)

Me:

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

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

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

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...

Excited for the following upcoming product releases:

Dark Mode GitHub
Dark Mode Jira
Dark Mode Kubernetes
Dark Mode Kafka Streams
Dark Mode WebEx

Don't trust Evangelists when they say product X is easy 85% of the time

Singalong

"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.

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?"

I'm going to throw myself into a pile of used heroin needles and hope i get stuck with whatever the hell this guy has to somehow be a manager while also being this retarded.

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.

Job posts that look for experience in everything! Experience in large scale enterprise kubernetes bullshit! What the fuck is kubernetes, a Greek god?? 4 plus years experience in aws! 5 years experience in cloud infrastructure scaling! 5 years experience in working with stakeholders and collaborating UX design! 5 years experience in React Native! 5 years experience in noSQL! 5 years experience in firebase! 5 years experience in graphics design! 5 years experience in node CSS! And every javascript known to mankind! I would love to meet this legendary developer that every company seems to want! Sick of these ads that ask for god level experience in every development role or tech. It’s like they’re hiring one developer to write their entire system from scratch which would obviously require godly expertise in front back and every fucking end there is to fucking build

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.

I lost sleep because of Kubernetes...

Rancher you fucking cuck you didn't tell me ahead of time OpenEBS can't RWX YA FOKIN WANKER FUCKING DAFT CUNT PIECE OF SHITE BLOODY BELLEND

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?

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 went to this conference to see what’s new in MSSQL 2019, kubernetes container on azure and see what Microsoft has done to embrace open source community.

Speaker is from Microsoft, brings a Mac to the conference which I’m kool wit it,
but shortly after he started, Word crash at launch, PowerPoint freezes when switch between pages, azure cli can’t login properly.
And he goes ”this is awkward. “

I think my server got hacked, yesterday I made a new server on scaleway for the sake of testing I made a user called dev, with password dev. Forgot to change password before I went to bed.

Logged in today to find that load is 5x.x and this (image) in my crontab

Note to self: You are a disgrace, who the hell uses 'dev' as password for ssh on port 22 -_-

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.")

Sometimes I daydream about just selling out and doing the whole diversity and women who code kind of thing. Apply for the big tech companies and work my way towards becoming one of the faces of their bullshit company. I'm gonna get a long wig, tan myself brown, and wear subtle native shit like a carabao brooch or some Cheongsam-inspired work suit. And when there's a big work event or party, I'm gonna go full on White Rose from Mr Robot, smiling and shaking people's hands like I give a shit. Gonna try to look wholesome and innocent, all I really wanted was a chance to get into tech as a humble being.

I'm gonna practice a strong accent and I would tell humble stories about where I came from, that god sent me here, and about all the struggles I had getting into the field as a woman. I'm gonna step up to the podium and say shit like, "Women can do it too, we can kuh-hode!" Then I'm gonna stir up some shit like, "Why is the terminal black?" Gonna make my voice and hands shake from intense emotion (visible anger, almost crying), "Why is something that we use to do our bidding black? Are we not over the years of slavery in the past? What does a terminal represent? Slavery. You know what else is terminal? Cancer. Slavery and racism are the cancers of our society. We must stop this. Terminals should be in all colors and it shouldn't be black by default."

1. Point out a non-malicious thing and add malice to it. The more racist and sexist, the better.
2. Mention something bad that is not related to it at all.
3. Make them seem related in an attempt to make a point.
4. Fail to make a point.
5. Say "we must stop this".

I'm gonna look straight into people's eyes with a serious face while cry-laugh-cringing internally. "As a brown woman, this makes me sad. I have Kubernetes skills, you know and it hurts me." If I catch some people laughing even though I'm also about to fart from internal laughter, I will point at the whitest male of them all. "You, do you think this is funny? Because this is my life, as well as millions of other people like ME!"

Then I'm gonna curse all of the white men who obviously only got into this field through violence. Yes, Mike, I know you pointed a gun at the HR to get in. What else could it be? All you know is violence because testosterone! You don't really know Kubernetes, I do, I set it up all the time for my thousands of hello world applications and yet here you are, just walking in with your white boy genes and your guns and taking all our jobs away. "What do you have to say for yourself? Shame."

Then of course, some hardcore social media "journalists" are gonna capture this on video and people are gonna ruin whoever man I pointed out's life and say shit like, "This big white man laughed at this little brown chick while she was talking. Sexism and racism in one video. This is why tech is so toxic." I'm gonna allow myself to get caught with a boner (big plastic white bottle) and people are gonna talk about how they didn't use a real woman as the face of their women who code thing. "I admit, I was born in a body that did not align with my desires but just because I have a penis doesn't mean I can't wear a Cheongsam. Also, the fact that you're pointing this out is discrimination and I had enough of that in my life. Shame. This is why tech is so toxic. You accept black terminals but not Cheongsam dicks. Fuck you."

I'm gonna keep ranting about big bad white men while dating one. Of course, people will find this out and point it out. I would flip it and say, "See? This is the problem. You look down on people like me because you're all racist. Just because I'm brown doesn't mean I can't date someone who is white. Sexist. Just because I'm a woman doesn't mean I don't have a choice who to date."

I'll keep ranting about all the ridiculous shit, just calling people names every time they speak. Just shame them for no reason then after several years of collecting my diversity money, I'm gonna leak a porn video of me. A compilation of sucking white man dick with voice overs just saying "big bad white men" over and over again. Some really degrading porn kinda shit. "You know what else scales? My ass cluster. Yeah, baby, fill up my containers with your sweet, sweet, love juice."

God bless whoever hires me and make me the face of their company. They will be forever ruined.

Our hiring manager just pronounced k8s as "kuber neatos"

I will never say it properly again

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]

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.'

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? 😀

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

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

Just another normal conversation as a Kubernetes Operator

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

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.

Fuck!

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.

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

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.

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

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?!!!!

Real devs don’t take “time off”. Christmas break means two weeks to catch up on my Robert Martin book, implement that component/service for the side project that I’ve put off and continue that kubernetes course I bought that’s prob out of date by now.

Time offs more like designated training time.

By the way, merry Christmas.
And happy birthday Jesus 🙏

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

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 ✌🏻

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

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

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.

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.

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.

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

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.

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...

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?

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*

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.

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? ;--;

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.

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

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

Friends don't let friends run containers as root.

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!!!

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

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.

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

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?

Learn:

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

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!

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.

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.

Anyone else keep a "free time study" list because they cant keep track of what it is they want to do next ?

Mine is a mess of circuit analysis, personal application work, kubernetes courses, learning piano and re-learning C properly.

My mind wont let me approach only one at a time. Im almost always in this non-complacent rut of wanting to touch on everything as if each topic has its own momentum and ticking interest in my head that I have to keep fed.

And so I literally have an hour at night dedicated to piano, kube courses in the morning, and circuit analysis courses on lunch breaks. On top of my full time programming job.

Feeling hungry as fuck though for constant knowledge. Learn all the things, indulge constantly and never grow satisfied with what I know. I dropped out of college for my career and here I am now, wishing I could sit in classes all day and just do nothing but learn.

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

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

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!

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 unattended

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 working

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.

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

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?

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.

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.

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!

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.

kubectl scale tears --replicas=infinity

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.

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 ....

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

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

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.

What is Kubernetes?

Devrant app cant even open ten rants in a row without crashing. Oh of course you have android inside Kubernetes running on top of arch Linux on your phone and it works fine, please fuck off.

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!

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 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..

I’ve been writing a node.js service that automates kubernete commands so users aren’t having to constantly call for newly generated pod names and then container names and so on so forth.

For instance it would ask you if you want to delete a pod, Exec into a container, fetch logs on a pod. It would list all namespace, pods and containers for those pods for you to pick from by just providing a corresponding number.

With this kind of service assist anybody who is constantly having to restart, delete, fetch logs and delete with Kubernetes?

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!

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

I hate that I don't know how to kubernetes properly.

My works funny man.

Over 12 years we've built out a crazy amount of services utilizing several languages, paradigms and deployment methods.

Apparently we use to have a massive dev team or something but as of now its like barely 9 (that might include QA so like 6).

We have a deployment repo that manages the entanglement of everything on a kubernetes cluster. There you will be forced to work with python, bash scripts, ruby, some lua, and node.js. And of course alot of yaml files.

Move along to one of our many extensions or servers and you will find yourself needing to know angular 1.x, angular 9.x (right big jump), angular 7.x, Php (no frameworks), node.js (express spaghetti code, likely written when it first got hot), ruby on rails, meteor.js.

Sense theres very few of us and we're over customer engineering (fixing bugs primarily to prevent churn), that means Im crossing each of these domains and needing to understand each enough to understand a mess of code that on average 9+ developers have had their hands on.

Im exhausted. Even coming from an agency environment this is still brutal.

Soo.. Not default?

I called you to generate that file. Could you please do your job

The logo in the left container is Python. What is the logo in the right container?

Kong API Gateway in Kubernetes is a load of balls. Spent half a day trying to stabilise the deployment after I bumped its pod resource requests.

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!

I have never used Docker and/or Kubernetes. Motivate me to use it by telling me how cool it is.
I want to build a complete ci-pipeline but am too lazy to start... there is so much to do, and I don't know where to start.

Attended KubeCon this week in San Diego. Was amazing great speakers great ppl all around.
Its amazing to see an open source community get together to share. I was not expecting there were goin to be more than 12k attendees!!

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*

Sharded Deployments on Kubernetes

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?

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.

I need to figure out a good way of managing, deploying and rolling back a live application. Perhaps just using docker-compose is the way to go. Though I want your ideas.

Thanks

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

Anyone using Kubernetes? Just want to know how much many people actually you it vs the actual hype there is around it

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've been saying Kubernetes and laravel wrong for an entire year. Coober-neats and larvol. Oof

Do you have a good use case to start learning kubernetes using the 300$ Google cloud startup bonus?

I need to build up knowledge because my work doesn't do it, so it could be either docker, or kubernetes. Both has to be done in a cloud platform because I have to do this in my spare time...

So do you have use cases and tasks for someone who's completely new to kubernetes? Or should I start with docker?

Time for an exam about Cloud computing and deploying Microservices to the cloud using kubernetes, followed by another exam about Usage of scientific C libraries. This feels both so disconnected for being part of the same degree.

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

Dockerized mongodb or MongoDB Atlas?
Pros and cons of each.

DevOps hire said kubernetes sucks at scaling Dockerized mongodb. And there's a chance to lose data.

Dockerized mongodb would be faster and cheaper. But I don't wana risk losing data, if that's true.

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 👌

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 :/

"Container design patterns" don't depend on containers

Best Docker Hub alternative? Self hosted or cloud based?

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.

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!! 🙇🏻‍♂️🙇🏻‍♂️

"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...

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

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 😱

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

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.

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

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...

Bought two hp z230 and one hp z210 to setup as a kubernetes cluster at home.
The first two worked as expected to install Ubuntu 18.04 but the z210 just fails installation just at the end of.
I've updated the bios, I've tried different hard drive, (obvious I've turned off secure boot), I've downgraded the bios, I've cursed, spoken harch language at it and sprinkled it with holy water, still it fails.
A Google search the problem, one hit similar to my problem but it did not help me.
Currently I'm on my 5:the glass of wine, if not solved tomorrow I'm hiding it at work until the next "downsizing" and it will have an accedent from the 9:the floor.
I've spent 150$ on it but I have the economy to nurture my mental health... Not all the time but this time it feels worth it!!!

Setting up an IaaS Kubernetes cluster is a real pain.

Running ElasticSearch on Kubernetes :: what are your thoughts?

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.

Anyone attending Kubernetes Forum Bengaluru in India today?

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...)

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!!!

Just a quick rant to express my distaste that the AWS ALB ingress controller for Kubernetes doesnt expose any useful metrics. I just wanna know the target response latency is that too much to ask?

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.

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.

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?

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.

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

Don't know how it works but I am really confused why orgs are so obsessed with kubernetes native infra .and migrating hell all to it

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.

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.

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 love

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

I’ve been assigned a Kubernetes task and I must say I really hate this shite. I’d rather code than be doing this 😑😶😑
