Job interview

Oh, Elon.

Apple had great idea... World just wasn't prepared for wireless... 🤔

This week was my Boss's wedding,
So had most of the week off.

Took the free time to solidify my understanding of Docker.

Last night, I was finally able to Dockerize our whole architecture.
Deployed it today morning. Running without hiccups till now :')

Feeling amazing.

Use Docker, it's awesome because you won't need VMs anymore.

Using Win7: You need a VM for running docker. 😫

what if we put docker inside a docker...

I have my reasons that Socrates once tried to understand how Docker works, because I have exactly the same feelings.

So i heard that docker is now a thing and decided to put my servers into containers as well (see image)...but somehow I still don't understand how is this supposed to simplify deployment, vertical scaling and so on...? :D

My every day life

Docker is starting to look like windows...

Devops though

Docker: "Build, Manage and Secure Your Apps Anywhere. Your Way."

Also Docker: "To run Linux in Windows, sacrifice 3 virgins."

Guys, my unfortunately daily rant of my pm

I was told to create a docker env for our team. Good. Document the process so everyone can know what to do. Good.

My PM follows what he wants to instead of step by step and changes whatever he wants to.

I am asked for help because he doesnt know. No prob.

Me: "Do this, do this and.."
PM: "that doesnt matter, trust me, I could change it and.."
Me: "...and it wont work"
PM: "I know suff too, check" *does his changes aaaaaand doesnt work*
* awkward staring*

That happened a while ago.
This week, he crashed his git repo because he was doing things in docker team (including him) decided not to.

Took me more enough time explaining him "you are not supposed to do that in the container" funny fact he wanted to prove that his way was right and even if he did my way it would crash.

Sooooo he did my way just to prove how wrong I was. Everything worked flawlessly. Rage-still-awkward staring.

Plus the "aww that's weird. I dont know how this happened"

F*cking recruiters don't even know the right words to look for matching profiles ...

"Free" 😑

Switched from typing 10 docker commands to docker compose yesterday. It was pure magic.

My boss says "cocker" once (referring to docker) a teammate and I make a meme of that, allways we have to talk about docker we say "dicker" or when we have to talk about git we say "dick" like "dick commit, dick pull, dick push".

senior devops in the school IT dep: "gcc is not working, it keeps telling theres no input files when there is, and its failing most of my builds"

are you sure sir? Give it another go

(Meanwhile my friends managed to sneak a "fixed image")

see? it works.

Senior Devops: " I swear it didn't work"

(we giggle)

check the last build's .bashrc

>alias gcc= (the error message e was referring)

Senior Devops: "MOTHERFUCKERS"

Actually its just your infra that we pushed the image to, school infra is unaffected

I mean it was fun while it lasted.

Have started using Docker since last few weeks.

* Mind Blown *

So this client wanted a demo on Dockers. So I gave the demo with some microservices running on different containers. Later the clients come back and say, "Docker is good. But please fit all the microservices in one container." I say but that defeats the purpose of microservices. But no, the client say. I tried explaining but no is no. Shit!! Fine! Have it your way!!

I thought docker was a shipmaker or shipping company until today....

This time docker got my name right. C'mon Shascha😂😂

I'm a simple developer.. Now wtf is docker...

"Don't install the Docker inside the Docker system, it will break your mind."

Useful docker aliases

alias dstart='docker start "$@"'
alias dstop='docker stop "$@"'
alias drm='docker rm "$@"'
alias dip='docker inspect --format "{{ .NetworkSettings.IPAddress }}" "$@"'
alias dls="docker ps"
alias dlsa="docker ps -a"
alias dps="docker ps"
alias dimg='docker images "$@"'
alias drestart='docker restart "$@"'
alias dcommit='docker commit "$@"'
alias dinspect='docker inspect "$@"'
alias dlogs='docker logs "$@"'
alias dcp='docker cp "$@"'
alias dinfo='docker info'
alias dcompose='docker-compose "$@"'
alias dlogs='docker logs "$@"'
alias drshell='docker exec -it -u 0 "$@"'

Are you using socat?

Any interesting use case you would like to share?

I am using it to create fake / proxy docker containers for network testing.

Docker, Docker everywhere

When you realise there is an docker image for docker.

WHAT THE FUCK IS THIS SHIT?

Just....

So we started looking into docker. As always I needed to do the research and I was fine with it.

We have 4 projects that are sold into one suite so logically I follow the microservices build structure.

3 months later after everything has been set up, we get called into a meeting. The whole suite should be a monolith as microservices doesn't make sense to the people planning everything.

Ok pulled my current plans out abd made everything a monolith. Just note I also get pulled away to other Business Units to do work for them.

Get pulled into another meeting 2 months later. Why isn't the docker containers in microservices!? It is stupid running as a monolith and we should've done our jobs better etc...

After the meeting my manager and I just sighed and walked to the office. So basically 5 months doing the the exact same thing we did in 3 weeks.

Now they want to develop other services and want to strip every method into a microservice and bundle it together.

Life of a DevOps engineer right!

Quote from Docker site: "anyone with Docker and an editor installed can build and debug the app in minutes"

Really? I'm two days in and still can't get this damn thing to work. And no solution in sight. Command line tools... sheesh.

Everyone in the office is amazed to discover that VS Code has a UI for Docker... Guys... this is just the "I" in "IDE"...

I fucking ❤️ Docker

You know what? I'm gonna write my own WordPress theme and I'll write it in my own docker compose.

When you spend a few days getting a monolithic LAMP app working in Docker so we don’t have to follow a 12 page install procedure... only to have your senior say “that’s not the way we do things around here”

After 1h of work, research, one ugly hack and 2 unexplained laptop power outages i made it. I shrunk down my docker container from 800MB to astonishingly small... 500MB...

In my defense: the python libraries take up 300MB of space.

i'm now running a docker-container on my home-server just to play minecraft with my girlfriend.

Hey docker

Eat my ass

The project tech lead asks me to add some Docker configuration files sent by the client to a project. He gives me a zip file and I unzip it and add the files to Git. Job done.
Later he checks the commit and starts bitching because I unzipped the file and it should have been added as a zip. After much debate trying to explain to him that Docker wouldn't open the zip file to search for the Dockerfile he just says "Can you just do it? I double checked with the client!". I give up after giving him all the arguments why he is wrong and do it.
The next day the client checks the commit and comments bitching that I included the zip file and not the contents of it.

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'm not knowledgeable when it's about Linux, so when I want to do some stuff I always have to take a f*cking lesson and a half. Could someone please explain to me what Docker is?

Current status: i should have gone to bed hours ago and there are other things i need to do, but right now i'm compiling ffmpeg in a docker container

Took a short break from work to express my feelings through memes

lies...

Oh Docker, why do you give me false hope...

Hey there!

So during my internship I learned a lot about Linux, Docker and servers and I recently switched from a shared hosting to my own VPS. On this VPS I currently have one nginx server running that serves a static ReactJs application. This is temponarily, I SFTP-ed the build files to the server and added a config file for ssl, ciphers and dhparams. I plan to change it later to a nextjs application with a ci/di pipeline etc. I also added a 'runuser' that owns the /srv/web directory in which the webserver files are located. Ssh has passwords disabled and my private keys have passphrases.

Now that I it's been running for a few days I noticed a lot of requests from botnets that tried to access phpmyadmin and adminpanels on my server which gave me quite a scare. Luckily my website does not have a backend and I would never expose phpmyadmin like that if I did have it.

Now my question is:
Do you guys know any good articles or have tips and tricks for securing my server and future projects? Are there any good practices that I should absolutely read and follow? (Like not exposing server details etc., php version, rate limiting). I really want to move forward with my quest for knowledge and feel like I should have a good basis when it comes to managing a server, especially with the current privacy laws in place.

Thanks in advance for enduring my rant and infodump 😅

I didn't really find the usefulness of Docker until I used Docker Compose. Deploying our architecture with a simple 'docker-compose up' FeelsGoodMan.jpg

I have been learning how to dockerize entire projects this week, and I have to say, Docker is the best thing I've come across in a long time.

That is all

I have spent the last 24 hours trying to connect a postgres db and a docker contained application both running on the same vps.

What no one told me was docker applications run on a separate network interface…

I need sleep...

Learn enough docker to convince my coworker that it is not the solution to EVERY problem, especially not to our problem

Where have you been all this time... Docker? 😀

Fuck docker documentation.

Been hearing about Docker being the coolest new thing for 3 years now. Please stop it!

well... I'm not sure...

I HAVE ACTUALLY SEEN A GUY ATTEMPTING TO CREATE A DOCKER IMAGE *INSIDE* ANOTHER DOCKER CONTAINER!

I have considered asking why, but then concluded that not knowing makes it a lot funnier.

Oh boy, finally something to rant about.

I got hired in a "small" company (not even 2000 people in it), then got "shipped" to a way bigger company. Basically, I work for this company (the french biggest internet / phone service provider) but in the name of my own. And this since last wednesday.

First off, I'm fucking stupid. After leaving the big company that I was in before, I swore to myself that from now on, I would work for smaller companies, mainly because I couldn't stand the inertia that big company have. You ask for something, you get it a month and a half after. The old company has about 6000 employees... This company has 98k people in it. Fuck. My. Life.

Now, to the rant: Orange (the company) decided that they had to move their office somewhere else. They set up a lot of things so that all we needed to do was to put things in boxes, to work somewhere else until next monday, then we could go to the new office on tuesday morning.

Keep in mind that I have been there for 8 days: I keep learning how they do their stuff. For example, if I need a specific docker image, I can't get it from the Docker Hub, the download will fail. However, if I hit an Orange subdomain's registry, I will get this image from a mirror. Because fuck logic.

When we join the company, they give us a Windows laptop ("yeaah we have useless but required Orange softwares that don't run on Linux" "Yeeaaah fuck you") that have a specific VPN allowing us to use the Orange network and, in theory, you can download docker images or clone orange repositories from that network.

In practice, you can simply just go fuck yourself. Why? Because whenever you want to curl, wget or pull anything (or even pip install), your connection keeps being shut down while it waits for the response's header.

The worst part? According to my (new) boss's evasive answers, the way to fix that works with glue, sticks and the power of the Force.

WHY THE FUCK DO YOU ENFORCE US A SHITTY OS FOR DEVELOPMENT, WHEN THE TOOLS YOU SHOVE IN IT WITH A FAKE SMILE DON'T EVEN WORK, AND WE HAVE TO HACK OUR WAY TO FUCKING WORK?

So I've been working a lot with Docker lately (who isn't) and there was this one service always DIEING on me.
Docker logs showed me that it was killed because the container was unhealthy.
I researched for a whole day and couldn't find it...
After I got home it hit me like a hammer...
The healthcheck uses basic Auth and the password was changed yesterday...

How the fuck could I start to try every shit before I even checked if the request done by the healthcheck is working...

FUCK ME I'M SUCH A MORON SOMETIMES

Docker is so fucking infuriating when it doesn’t work, but amazing when it does

Today I built an ASP.NET Core 2.0 Rest-Api within a docker-container.

Then I ran a docker-container with the compiled ASP.NET Core 2.0 app behind a nginx router.

It was purely magic!

:)

dicker-compose up
focker-compose up

But why??

Perfect for continuous ingestion/digestion 😏👌

Teheeheeheee

Hey, we want that devop thing that everyone is talking about!

A Docker build times out and returns "unknown blob"

that moment when you have to learn Docker at work, so you convince networks teacher to do that in classes.

Definitely Docker.
Do whatever you want, whenever you want.
The pinnacle of flexibility.
Try out everything, without installing anything.
Deploy with the same environment you're developing with on your local machine.
It's brilliant!

Docker + windows containers + Windows 10 = fucking nightmare 😵

"Let's migrate the entire environment to Docker."

Oh crap. Please no. Anything but that.

Containerize everything
My containers are too big, let's just remove some useless binaries...
Later
~ $ less /var/log/foobar.log
/bin/sh: less: not found
~ $ cat /var/log/foobar.log
/bin/sh: cat: not found
~ $ ls /var/log/foobar.log
/bin/sh: ls: not found
~ $ su
/bin/sh: su: not found
~ $ exit
/bin/sh: exit: not found

So a friend just told me one of his websites just got hacked and replaced with viagra advertisement.
He basically avoided joomla updates in order not to break something.

On the weekend I'm going to show him how to quickly spin up a docker environment for testing updates.

me: *hosting docker registry for our team*

me: *sets up ssl and cloudflare dns and shit*

me: *tries to push to registry*

my pc: *413 rEQuEst EnTITy tOo LarGe*

me: *spends 4 hours scrutinizing the shit out of my nginx configs*

me: *finally finds cloudflare sitting there rejecting all of the requests... that cheeky bastard*

Docker, what the fuck are you storing?

Tried installing docker on windows today (for an experiment) and after it finally installs and goes to start up i get the hyper-v required, installing will prevent virtualbox from working.

Yea... FUCK NO! There goes that idea 😡

Docker.

I'm learning docker and I just started a container running a Linux distro.
What was the first command I run in the container?
rm -Rf / --no-preserve-root

Forget about a missing semicolon. I was forwarding Neo4j to port 4747 and calling it in Asp.Net with port 7474 in Docker containers. It took me 6 hours to figure that one out. Lol, It's time for the weekend.

I think I'm getting crazy...
Yesterday evening I finally thought it was a great idea to set up Gitlab CI to let the server build (ng cli) and deploy (via FTP) an Angular5 SPA on commits on the master branch.

BUT...

The npm package "vinyl-ftp" thinks it is pretty fucking funny to just randomly stop in the middle of uploading files or just upload some files with 0 bytes in size.

WHAT THE HELL?

After some hate infested trial and error, it seems that the more parallel channels I set up, the more chance I get that all files are correctly uploaded, but never all.

If anybody here happens to be some kind of mighty byte bender and knows what to do, I'd be thankful. But I will probably try out a different client in the docker image...

How the fuck do I convince my company to use docker?

I am learning about CI/CD and DevOps, and i finally made my first build/deploy/unit test script.

I use arch btw

Other Team: "our builds don't clean up properly"

*docker rm -f $(docker ps -a)*

Other Team: "our builds keep filling up machines"

*docker rmi $(docker images -q)*

Random Team Member: "My builds keep failing on service foo randomly exiting"

Other Random Team Member: "Why is there no caching on our builds"

...

team panics thinking it's their fault as our main job still passes, as it's on another machine.

...

When we find out after tracking build history

KMS

WHAT THE FUCK DOCKER??
WHY ISN'T THE IMAGE SMALLER WHEN I REMOVE APPS?!?! Just don't understand it, but whatever. Still weird.

As you guys may or may not know (or may or may not give a fuck), I'm currently part-time studying to get a diploma and get the fuck out of my country. Since I have to write a 40-pages long "end of study dissertation" about something we personnaly have interest in, I decided to teach myself about DevOps.
In order to prepare it, I decided to get a Raspberry Pi, install Docker and Jenkins (as a container) on it, and handle my multiples websites on it, and build a huge fucking website around which I would write my dissertation about.
But man, I'm starting to loose hope, I get to bed at 2 AM every night because I'm trying to make some basic shit work until I realize that I just CAN'T what I want because of tons of reason, so I try to lower my expectations, and it's frustrating. Yesterday, a Ruby on Rails image I created was perfectly working, tonight MySQL throws an "host not authorized for this mysql server" error, and I don't know what the fuck is happening nor if I can do anything about it.

I love teaching myself new stuff, but I have to admit, it's waaay harder than I expected

I’m just in love with Docker.
My enterprise finally accept to give it a try.

NB : We have tons and tons of VM for nothing.

How are you doung this docker?? 727 commits on just 2 hours??

Tonight, I gave birth to my first fully functional and deployment-ready dockerized application, "lestadium_web_1"!!
The big baby contains a Laravel showcase website with some React already in production! Big bonus with that, it's connected to a database, and I managed to setup some environment variables so nothing too dangerous is built within the image!

Fuck, that was exhausting but I'm so happy to finally understand how to make my stuff work, how they work and how to find some examples to get inspired from 😍

Spend two days struggling with environment variables not being available in python script running on a docker container, tried providing environment variables directly, not working, tried providing a env file, not working
.
.
.
Turns out I was passing variables to the wrong container fml

Can someone explain to me why there are 10M+ downloads for CentOS from docker?

*ssh into server*
*runs 'sudo systemctl start docker'*
*ssh into server again*
> Permission denied

How docker? How are you destroying the ssh servers auth?

Never new setting up a mail server could be a huge pain 😭

Two days still no luck... Let's see how long it takes

Now i COULD create a docker usergroup

And i also could alias docker="sudo docker"

Just got our development Laravel docker image down to under 124 MB with alpine linux. The satisfaction...

Docker is awesome for minimizing environment problems.

Current side project needed a database, a web server with php and a transpiler server running. Before, other people developed using XAMPP on windows. I dockerized the project and have now just one build script setting up everything the app needs, regardless of the underlying operating system.

Being in a university that has an eSports Academy is less exciting when you're part of the team maintaining it weekly... Well, at least the part where we had to set up a local cache server with docker & nginx was fun

Wtaf?

why are there only two of seven characters of the Webservice password, when the request goes out in my docker container?

Answer:
The password was retrieved via PHP getenv()

Soooo....
If there is a $ in an environment variable, this $ has to be escaped with $$.

fml

Everyday another thingy to learn ^^

xD

Just had one of those days.... totally learned A LOT about how to properly profile a Linux box using Brendan Gregg's( Netflix ) USE method. Only problem is... I didn't make any actual progress on my application project itself. 😩😩😩😭😭😭

Docker is a fuckin bi*ch... build success at #22. What a Friday! Tomowzz gonna be lit if I don't get any calls tonight.

There is this docker guy in our enterprise.
Always, he is told there is a challenge in software operations, he brings up the solution "move it into a docker container and the challenge won‘t be a challenge anymore".

........

Don‘t get me wrong.

I love to use docker as a technology to host my apps.
But for me it is not the golden hammer technology which cures all dread diseases on this planet.

Sometimes it is just overhead for the solution of small challenges.

6 months later
Still don't understand Docker

When you really want to understand Docker but it makes no bloody sense!

docker service scale serviceID=5

If only scaling my bank balance were as simple as docker swarm scaling !

It's so frustrating to see how PHP images for Docker are nicely set up, well documented, come with Apache or Nginx, almost ask you to let them pay your bills, while you get almost nothing from Ruby, and when you think you finally made something that works, it behaves like a fucking drunk irish

Ok tomorrow I'm gonna kidnap one dev or two and I'm gonna release them only when I fully fucking understand how to fucking send an image to a private registry goddamnit

> has 9GB free on 80GB SSD
> runs docker rmi $(docker images -q)
> has 37GB free on SSD

oh .-.

Yes! My SearX instance is working in an Amazon ECS server! It was working out of the box without the need of any extra configuration. But I still would like to know how to configure SSL. I'm currently using port 8888. This was my first contact with Docker, it's very awesome what you can do with it, can you recommend me some nice guide?

URL: wait! I was only testing, I won't pay more for vCPU per hour! No way!

Starting to migrate apps from a messy structure to docker containers. Have not worked a lot with docker before so i'll hope it goes as smooth as people told me

Hi guys,
I want to ask if anyone would like to join a PAAS project I'm starting? From the start it will be opensource and then when it evolves we may consider making a hosted service as well as a enterprise version. No one is going to be payed by entering this project. I'm looking for people that have experience with docker and docker swarm mode or can program in php, make console apps and that can make a UI.

Just submitted my first pull request ever. Now that's exciting (for me at least)

Just installed docker on my windows laptop and booted up a ubuntu image. Worked flawlessly 😍😍😍

Spending hours trying to figure out why the stack just won't work with SSL. Nearly lost my mind as we started feeling dumber than ever. I really started to doubt my skills after it did not even work with the most minimal nginx site config I could imagine.
The next day I discovered that we missed the 443 port mapping in the docker-compose file...it only had port 80 mapped.

Yup, stepping back from a problem and getting some sleep is really worth it sometimes.

Docker daemon: size not found

so I installed nginx on my server this week. I feel like a giddy kid now installing one self hosted app after another. REVERSE PROXY ALL THE THINGS!

Right now I have reviewboard and drone (drone.io) installed. Any of you guys have suggestions for other cool stuff to try out? Mostly interested in something with a web API that can do fun stuff :)

Docker for Mac loves burning my CPU. Even if I delete all images and containers and do a fresh reinstall and JUST have Docker for Mac running, I always see crazy CPU usage on my Late 2016 15" Macbook Pro.

slow in osx as expected

Docker y u no mounting volumes on Windows anymore...?

World y u use Windows at all?

Note to self, y u no problem-solving instead of devrant posting?

You can connect to Docker containers directly via IP in Linux, but not on Mac/Windows (no implementation for the docker0 bridged network adapter).

You can map ports locally, but if you have the same service running, it needs different ports. Furthermore if you run your tests in a container on Jenkins, and you let it launch other containers, it has to connect via IP address because it can't get access to exposed host ports. Also you can't run concurrent tests if you expose host ports.

My boss wanted me to change the tests so it maps the host port and changes from connecting to the IP to localhost if a certain environment variable was present. That's a horrible idea. Tests should be tests and not run differently on different environments. There's no point in having tests otherwise!

Finally found a solution where someone made a container that routed traffic to docker containers via a set of tun adapters and openvpn. It's kinda sad Docker hasn't implemented this natively for Mac/Windows yet.

My journey into learning Docker, chapter {chapter++}:

Today I learned that when you use a database image in your docker-compose file, and you want to rebuild the whole thing for reasons (say, a big update), then if you change your credentials ("root" to "a_lambda_user" or change the db's password) for more security, and you rebuild and up the whole thing... It won't work. You'll get "access denied".

Because the database (at least mysql and mariadb) will persist somewhere, so you need to run "docker rm -v" even though you didn't use any volumes.

I love loosing my fucking time.

What's your experiences with Docker?

Trying to use docker for the first time, and getting nowhere. I think I'm actually unlearning how to use a computer.

Me and a couple of my friends at the IT dep stationed in the school servers will do something a little interesting for tomorrow

we will alias gcc with the error message you see when the compiler does not recieve any input files in the Docker images in their build CIs.

oh dear

When your the only one who wants to use Docker in your work but your team won't.

Something I stumbled upon. Happy valentines day 😊😊🐳

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

TLDR:
Why can I still access a container after its image is deleted?

I needed to clean up my disk of clutter, many containers and untagged images I created for experiments. So I ran
`docker system prune -a`
That removed all the unused images, stopped containers and those not dangling as expected.
But I still have a running container and I expected that it's image won't have been deleted but it was.

I stopped and restarted the container thinking to myself, this shouldn't work but it does, I can still access the port in my browser.

Can please explain to my beginner brain why that happens?

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.

fascinated by docker and virtualisation.
anything fun to try out? :)

Docker rant, and "learning to code" rant in general:
Fresh install of docker (Mac), pulled latest containers, pulled latest master branch from codebase, shell in to run the test suite. I source env variables, migrate, looks like business as usual, then the test runner kills itself for no (apparent) reason.

Check out console logs from docker, missed heartbeats from celery and some shit about a time warp. wtf is that?

OK whatever, do the normal "restart my laptop, restart docker, try again" and now two hours of me staring at ./manage.py test -v 3 -l DEBUG --keepdb (appname) wondering wtf is wrong here.

Meanwhile I am not a seasoned dev, with 2-3 years of Javascript, the past 6 months I've been learning to dev in Python/Django using docker.

Only colleague on at this hour can't think of anything, so I file a bug report feeling like a dumbass for not knowing wtf broke upstream in the past day/week, and imagining the "real" devs (i'm in the product team, not the engineering team) losing their faith in me that I could be a competent dev someday

Cant shake this feeling of shame of being ignorant, like I should automagically know how to fix this.

I think I'm obsessed with Docker. Started off as a PITA and now I can't seem to do a project with out it :/

Dear Docker for Windows I know you exist to make devs on Windows life easier. But DEAR GOD, with all the firewall/group policy problems..you have been the pain of my existence during this short time developing on Windows.

Literally have a countdown on the time left until I get to no longer do a rain dance for my development environment to work.

Docker broke, swarm was a bloddy house of cards, from the first days of swarm, consul was somewhat bent around that crap
No docs, no one has a clue, no support and got somewhat backstabbed

Well... Maybe i should do something with wood or orchids ...

Just added a group to my user without the -a option....

Result: my user no longer belongs to the sudo group and I do not have access to the root user or sudo.

Hopefully the group I added was docker, time for some container shenanigans to escalate my privilege back.

I love docker, but I must confess that I do not wait for the build looking to the screen 😅

What certifications do you guys have, and which do you recommend having?

I'm currently pursuing AWS Developer Assosiate, and in the future Google certified Android developer and MongoDB developer.

Been thinking about Docker but it costs too much

don't you love that moment when you are trying to set up a test environment but end up spending 3 days trying to get one little service to work?

I can't seem to find any auto dns that works with minimal configuration to use with vagrant or docker...

I'm in the first semester at my third college, working on my B.S. degree. I get a job in the finance and operations IT department doing web development. I get to use lots of tech I've never used before, like Python Flask, Docker, Redis, Azure, Slack, Microsoft VSTS, Portainer, MongoDB, Oracle database (weeeeeeeeeeee), and who knows what else awaits me. It took a week to get me access permissions to various systems but that's fine. I expected that.

* It's the first time I've ever touched Docker. I manage to break it so badly (somehow) that I BSOD my Win10 machine. Everyone in the office congratulates me on such a feat.
* I get assigned to an internal app management site to not only patch because it's currently broken but also improve. Coming from a PHP background, I've seen some nasty code. What I didn't expect was the same exact same anti-patterns and coding "practices" (examples: everything in a single file, all forms on a page POSTing back to itself for submission, sloppy, mostly uncommented, densely packed code) in a Python Flask project. I was told it was thrown together quickly by a previous employee who made this as his first Flask app, but this was not what I envisioned.

It's as if everything I do in my career is to prepare me to untangle the next monster code base I come across. I feel like the universe is mocking me.

That's cool. Bring it on. I'm ready. I'm enjoying this job anyway. 😎

WHY NEXTCLOUD, WHY DOES IT HAVE TO BE SO FUCKING COMPLICATED TO UPGRADE YOU TO THE LATEST VERSION??????

NOT ONLY DID THE DATABASE MIGRATIONS NOT RUN, YOU DIDN'T HAVE THE UPDATED VERSION OF THE FUCKING AUTHENTICATTION PROCESSOR IN THE OFFICIAL SERVER DOWNLOAD SO THE WHOLE THING WAS BROKEN AFTERWARDS.

I'VE WASTED 4 HOURS ON THIS FUCKING UPGRADE 😤😤😤😤😤😤😤

Forget about everything I could say these last 2 days: I'm having as much fun with Docker than when I first discovered Ruby on Rails 3 years ago 😍
I still don't understand everything with docker-compose & shit but so much things are way more clear when you try them out!

Today I finally solved a docker problem I was stuck with for 2 days.
For some reason it didnt want to download the needed images although colleagues could download the same images. Every time I tried it resulted in a Python IO error.
Today I had enough of it so asked if I could join another project. I had to download the exact same image for that project and it worked... Setting up the first project worked as well since I had these images already.

I still dont know why it didnt and later did work, but that is the life of devs.

Dear Docker Support,

You suck.

I just noticed there are loads of docker memes out there on the web 😋 amusing

Haha, Docker just got a shit ton of negative PR for hiding the download behind a login. The hackernews post is ranked place 2 right now and if you haven't before you now know about this dick move of these shitheads too.

Docker has changed my life.

Fucking docker swarm. Why the hell do they have to change the way it works so damn often. Find a good workthough and its not fucking valid anymore cause swarm doesnt use consul to catalog swarm nodes anymore. Well fuck thanks docker now i have to rethink my architecture cause you fuckers wanted to do something half assed.

Sad fucking thing is the change that made you do that shit in the first place doesn't work right for ssl so your damn mesh network is fucking useless for any real world uses unless people like me rig the fucking hell out off it.

Another fucking thing how the hell haven't these fucktards added a shared storage yet, come the fuck on.

When your VM crashes while running CDC tests before you have a chance to push. Porque

In the world full of VMs be someones container <3.

Everytime i think im going to learn about docker, someone comes along with another comment about how docker isnt so great.

It took me an entire hour to figure out why my https gave me a Connection Refused error in my browser. Apparently I had configured port 433 to be published instead of 443, another hour wasted.

I realise the latest trend is to leave GitHub, but I will be keeping my Repo's on there for the foreseeable future, or at least until GitLab can get their shit together.

They seem incapable of hosting their own data, and having just wasted 8 hours of my life trying to install this POS I'm unable to trust the platform as a self-hosted model either!

Just got to know how awesome Docker is! LearnUps are turning out to be awesome!

So yesterday i upgraded the packages on my pi, docker being one of them. After that all my containers were down and couldn't be restarted. The error message said the container was already started...

Using the internet i found out other people had that problem too after upgrading to docker 18.02. I ended up removing all containers and searching the bash-history for the docker-run-commands to create new containers.

DOCKER, LISTEN UP. YOU'RE COOL AND SAVED ME A LOT OF TIME. YOU HAVE MINOR ISSUES, BUT THAT'S OK. BUT IF YOU CRASH MY CONTAINERS ONCE MORE I'LL GO CAPTAIN AHAB ON YOU.

Oh, and some more armhf-containers would be nice. WHY CAN I ONLY RUN DOCKER-REGISTRY ON AMD64-ARCHITECTURE?

Installed celery...
ran my code...
error...
module 'celery' not found...
wondered why...
reviewed...
didn't install it properly in Docker...

end of story

Let's see if CoreOS can give me better container performance than Ubuntu...

Spent the weekend geeking out getting my head around a proper Docker based environment for my development env at home and for the team... 90% done and I couldn't figure out why I couldn't start my Splunk instance up.... I'd set the default logging to Splunk.... Chicken & Egg probs!

But how awesome is docker with portainer and app templates eh?!

I'm getting really astounded by how little my co-workers know about anything about server setups. I've created a local Docker environment that is to be used by everyone to help manage the applications, but NO ONE seems to understand what I made let alone know what Docker is. For some reason they see it as another VM.

They're just content with it works, I can run my PHP application, and if they have a problem, rather than try and find out themselves, they just come straight to me.

I can pretty much tell that this team is going to be screwed when I move onto my next role.

Docker pisses you off? Everything worked fine and suddenly doesn't?

$ docker system purge

Reset Docker

Reinstall containers.

Profit.

Spent about 5 hours trying to figure out why php-fpm 7.2 was sending a timeout to nginx inside a CentOS 7 container. In the end I couldn't figure it out, downgraded to PHP 7.1 and then everything start working fine. I really hate using CentOS for containers since it also requires privileged mode to be able to start services. Hopefully I can move away from using CentOS for containers soon since the base image is also quite fat.

Docker the company is a mess.

A good Day to learn something new!

Docker! I'm coming!

So, right now we upload production code by means of FTP.
I said it would be better to use continuous deployment using Docker, but they said it was overkill (I work at a small company).

Because manually uploading by means of FTP is so much better right...

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!

docker y u no fucking start...

Been trying to learn Docker when I hit a brick wall. How do I use nginx reverse proxy + letsencrypt with multiple containers? I only managed to do it with a single container. Using docker-compose or stuff like that I guess?

TFW when you've been trying to figure out why your apparently flawless JPA database query won't return anything and realize you forgot to populate the database after setting up the docker-image....

Always spend an hour debugging your container services before you think to clear the browser cache.

This more of a tifu but to be short and concise..

4 months into the job, still learning the hang of docker, exposed a critical port that collided with a node, crashed our entire internal docker ecosystem. What a day...

ive never been so stoked on a hello world before.
reverse proxy to a remote server parsing php.

First time working with docker: now I'm in love with him.

Since some started posting pics of their work machines. Here's mine: an Asus ZenBook 3 deluxe. Nodejs dev.

Having a shit of a time trying to figure out why Docker containers are not accessing other containers via domain names as they should technically be going through the jwilder nginx proxy container.

Why can't environment setups ever be simple?

Has anyone noticed that all this microsoft "open source" thing is about docker?

My standard pattern for using 'time saving' things (frameworks, scripts, new technologies) seems to be:
1) Get excited by how easy <new thing> is to use.
2) Spend the next 12 hours trying to work out how to work with this new shit.
3) Realise I'm now further back than I started.

Today has been docker.

Easy to run my new Wildfly docker container.... can I find the IP address to connect to? Can I fuck.

Did you ever forgot the dot at the very end of docker build command, when the Dockerfile is in the current directory? Best circumstamces when it happens in travis.yml (yeah, forgott a dot here as well) and like always the first build there fails :D

Did ever the first build in a CI worked out for you?

Why is Docker + SSL certificates so confusing? Or do I just have bad resources?

I just want to know how to compose an Docker, Nginx setup with encryption.

Boss told me to create a Docker Container for my Selenium Tests...

Mission Failed, my boss gave me a 32bit Windows mashine...

Probably i should install a new OS...

Just started experimenting with docker my god this is weird running Linux in powershell

Not much of a rant, just laughing at myself. Typed in docker run android instead of cordova run android and sat there waiting for a minute or 2 😂

installing oracle 11gr2 database via docker is so easy and quick rather installing to the system
Totally saved my time, now I can have more time for learnig

Question about permission in `docker-compose`

So far, I've usually used vagrant for local dev. It was nice, as I was able to specify `wack:wack` as owner of all files. However with docker compose, if I connect with exec and use `/bin/bash` I'm logged in as `root`. When I then run composer, it kind of fucks with the file permissions, as after it all new files are owned by root and thus can't be edited with an ide on the "host" system.

One hack that I found suggested creating an user and a group with same uid as on the host and use that instead of root. This just doesn't sound right to me. Any advice on how to handle this situation?

The problem with moving Docker containers from your decked-out dev machine to a VM on AWS when your boss has told you to keep costs down:

1. Start Micro instance, 1++ gig memory
2. Get Out of Memory error from app after 30 minutes
3. Goto 1

The tech adoption curve

docker is shit. It fills up the disk on its own whim and then crashes the server, and they claim it to be production ready. Stupid piece of software!
