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

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

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

what if we put docker inside a docker...

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

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

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

Docker is starting to look like windows...

Minecraft running in docker. Yessir.

Ignore the dishes, I'm moving out at the moment.:D

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".

First time seeing software charging me to not update from Docker

Don’t forget to clean up unused docker volumes once in a while...

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

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

WTF?

f.lux is alternative to docker ????

how? why? what?

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

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

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.

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 dcp='docker cp "$@"'
alias dinfo='docker info'
alias dcompose='docker-compose "$@"'
alias dlogs='docker logs "$@"'
alias drshell='docker exec -it -u 0 "$@"'

docker documentation is terrible. Mf'ers seem allergic to giving actual functional examples.

Watch me generate a 1-to-1 copy of the docker compose docs (real & true):

`docker compose --help > docs.html`

Junior dev at my workplace keeps telling me how efficient docker is.

He decided to solve his latest task with a containers in swarm mode.

As expected, things went sideways, and I had the joy of cleaning up behind him.

A couple of days later, I noticed that I was running low on disk space - odd.

Turns out docker was eating up some 60 GB with a bunch dangling images - efficient is a funny term for this.

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

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.

New to devRant. Didn't realise it existed before. What got me here - docker!

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!

Our software needs apache, php, mysql and node of certain versions installed. This is too many dependecies for our customers.

Let's dockerize!

Now they need docker, docker-compose, make, bash and python in a certain version. What an improvement!

I mean yes but hm.

how docker was born...

If someone asks me how I spent my 30s, I'll be like "oh, I waited for the Docker to build"

New dev prefers mariadb over postgresql, which is okay.

But his main reason is 'the smaller docker image'

What an argument, wtf

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

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...

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?

lies...

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

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

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

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

Docker is funny.

I'll try to fire up docker-compose and it will freak out.

Docker Error: "Oh man! Oh man! Something is wrong! It's probably not docker it's YOUR CONTAINER!!!! WTF DUDE!!!"

Me: "Uh docker ... your little systray icon indicates docker itself is broken right now...""

Docker: "No way man, i'm sure it's your fucked up container, must be something wrong with it!!!"

Me: "I'm just gonnna restart you."

Docker: "OK but I'm just say'n th----"

-restarts docker-

-restarts docker-compose-

Docker: "OMG It's up!!!!"

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.

I'm not sure is it a container technology or a zoo...

Docker is Whale
Docker Compose is Squid
Podman is Seal
Linux is Penguin

Are we live in the Arctic?

In my day off I was eager to try overclocking in my pc and this is how it went:

- Fucked up overclocking parameters for cpu and ram speed.

- BIOS is broken, had to take out gpu to do a reset taking out the bios battery.

- BIOS is up again, default values loaded, bla bla

- Did not try to fuck off anymoar with overclocking, just kept playing star wars and went to sleep safe and sound like a baby.

- Gotta work now. docker does not start, closes itself after tried to start, docker panic, I panic, tried to uninstall, tried to update. nothing works

- Then I remember bios default values leaves virtualization off. enables it again, docker still not working. I panic again, restarted pc like 10 times between disabling/enabling hyper-v in windows.

- Docker dies. not gonna change my overclock options again. silly me 🤦‍♂️

Why is this Jenkins instance running a Jenkins docker image on top

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!

:)

I hate Docker. I hate networking with Docker. I hate Hyper-V.

I've spent over a month dealing with problem after problem after problem.

Someone put me out of my misery.

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

!rant

I'm currently reading the Docker docs. This thing seems to be beautiful.

A Docker build times out and returns "unknown blob"

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

Oh crap. Please no. Anything but that.

Finally!
Got my Minecraft server running inside Docker to properly stream logs through Go to this shitty web interface. Fucking hell I didn't think this would be so fucking complicated!

Edit: Forgot the image :)

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

Ok, so I basically spent my weekend trying to work out why the fuck my python docker container would not connect to my mariadb docker container. Tried fucking everything, bridged network, host network, links (even though theyre deprecated), you name it. It would NOT WORK!

In my despair I finally turned to StackOverflow. There I was told 5min after posting the question that the reason was probably that mysql is a quite heavy service, which takes a bit to start up.

I thought to myself "Oh, get the fuck outta here, that can't be it, shit's way too easy to work!"
I tried it nevertheless by adding a 10sec delay before querying the database AND THE MOTHERFUCKING PIECE OF SHIT ACTUALLY WORKS!! So, I essentially just lost a weekend because I was too impatient... I think I'm gonna punch some trees now.

Docker + windows containers + Windows 10 = fucking nightmare 😵

Docker I don't have time for your bullshit tonight!

You're supposed to be this safe space where my code runs and neither the code or the god damn container changed.

Don't give me some bullshit about the container either, it's pretty clear docker itself is fucked ...

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

No Docker Hub. That's wrong.

Open source mail server?
I'm using Mailu but was thinking if there are other good options?
Also it is better if it has a docker image

So Docker Desktop only runs on Windows 10 Pro. Unfortunate for Windows 10 Home users that comes installed with their laptops like me. Gotta install the legacy Docker Toolbox

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

so, docker in windows looks like a mess, could not set up a laravel environment easily, then my last resort was to use a virtual machine and adios docker from my system

Docker, what the fuck are you storing?

Sad. Laravel Valet uses Nginx. What if your office system is using Apache and is heavy in using .htaccess?

Ok back to MAMP and Docker. I'll just use Valet for simple things.

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.

Dockers JSON output is garbage.

First, you'll get no JSON per se.

You get a JSON string per image, Like this:

{...} LF
{...} LF
{...} LF

Then I tried to parse the labels.

It looked easy: <Key>=<Value> , delimited by comma.

Lil oneliner... Boom.

Turns out that Docker allows comma in the value line and doesn't escape it.

Great.

One liner turns into char by char parser to properly tokenize the Labels based on the last known delimiter.

I thought that this was a 5 min task.

Guess what, Docker sucks and this has turned into try and error...

For fucks sake, I hated Docker before, but this makes me more angry than anything else. Properly returning an parseable API isn't that hard :@

I think I'm starting to like Docker.

DOCKER ON WINDOWS</rant>

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

"Millions of slaves"
"When you kill it, you kill everything."

-- Guy at work doing presentation about docker

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.

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

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

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

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

Build a docker image.
Adds config file .
Build cache ignores new contents.
Hours of trying to figure the shit out.
Bash into it.

GOD DAMN DOCKER HAS CACHED THE VERY FIRST VERSION OF THE FILE.

Hours lost with headcaches and thinking about existence. Fck my life.

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.

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

Don't forget, docker desktop will require paid licenses after 31/1/22

Docker Desktop remains free for small businesses (fewer than 250 employees AND less than $10 million in annual revenue), personal use, education, and non-commercial open source projects.

Just a friendly reminder to fuck docker and migrate to a better solution.

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

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.

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

So with the advent of Docker Desktop going premium we thought we'd buy a couple licenses... What did the HR team say?

"No, you're fine - we can just keep using it - how will they know?"

WHAT??!!! I will NOT be the one who gets brought into a multi-million dollar lawsuit because HR are a bunch of nitwits. I will fight this with everything I have so that when ouch time comes, i can say i didnt participate in the shady bullshit these people are recommending.

Why does Windows have to be so fucking useless when running docker. Everytime i need to make a change to the NGINX container, I have to restart the docker daemon, rather than rebuild and restart the container.

I would be doing this on Ubuntu, if I could install it that is.

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.

Everyone talking about Docker as the next big step in productivity. I still miss why Docker is so useful, to be honest, I see it as a "micro-vm " running your own software.

I have used this technology before but I really struggle to see where I could apply it usefully.

At this point, I'm thinking I'm just too naive about the issues it solves. So lemme go straight to the point:

1. How does Docker speed up your productivity?
2. How do you use it?

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.

here i go again, trying to convert my entire backend infrastructure to docker images on a sunday

FML

🤡

What's your experiences with Docker?

We have a customer that doesn't have a SINGLE linux admin. So now I have to fight with Docker EE on Windows Server 2019 (linux containers). Just fucking kill me already. Nothing works and when it does it just seems so shaky. Not like I didn't try to tell my team that linux containers on Docker EE for windows aren't officially supported and highly experimental.

But wtf do I expect from someone that STILL sells SAP and from someone that is stupid enough to buy it.

At work everybody uses Windows 10. We recently switched from Vagrant to Docker. It's bad enough I have to use Windows, it's even worse to use Docker for Windows. If God forbid, you're ever in this situation and have to choose, pick Vagrant. It's way better than whatever Docker is doing... So upon installing version 2.2.0.0 of Docker for Windows I found myself in the situation where my volumes would randomly unmount themselves and I was going crazy as to why my assets were not loading. I tried 'docker-compose restart' or 'down' and 'up -d', I went into Portainer to check and manually start containers and at some point it works again but it doesn't last long before it breaks. I checked my yml config and asked my colleagues to take a look. They also experience different problems but not like mine. There is nothing wrong with the configuration. I went to check their github page and I saw there were a lot of issues opened on the same subject, I also opened one. Its over a week and I found no solution to this problem. I tried installing an older version but it still didn't work. Also I think it might've bricked my computer as today when I turned on my PC I got greeted by a BSOD right at system start up... I tried startup repair, boot into safe mode, system restore, reset PC, nothing works anymore it just doesn't boots into windows... I had to use a live USB with Linux Mint to grab my work files. I was thinking that my SSD might have reached its EoL as it is kinda old but I didn't find any corrupt files, everything is still there. I can't help but point my finger at Docker since I did nothing with this machine except tinkering with Docker and trying to make it work as it should... When we used Vagrant it also had its problems but none were of this magnitude... And I can't really go back to Vagrant unless my team also does so...

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

I’ve got to say, I used to blow off Docker as some trendy, hipster technology that people only use for the cool factor but ever since I tried it out, I’ve used it for about 80% of my personal projects...

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 ...

I hate this company so much. I was tasked to write a simple program wrapped in an API. They gave me freedom of choice to use any language and technology because I said it'll be deployed in docker anyway.

Now, when they gave me the server, it's Windows Server 2016, of course, without docker installed (or even supported in any way). The access is done via TeamViewer for which I receive ID and password by calling a guy.
Oh, and everything runs as admin. "It's easier that way and we always do it like this."

Today I managed to set up a working docker project locally. Feels like I'm about to take over the world. Sooo much smoother than installing everything the normal way. And so clutter free :)

Here is my day.
1. Mac wanted to perform an update.
2. I said Okay, Do it.
3. It took sometime, I thought WTF let's force reboot.
4. Shit happened. I am unable to boot as install is corrupted.
5. Reinstalled a fresh copy. I didn't have a backup.
6. Realised that my two days of work is gone since I haven't pushed the code to github.
7. Found out that I made a docker image with all of the latest changes.
8. Now trying to decompile and rewrite the code from the jar in docker image.

- Use docker so it works on any machine
- The server only starts on Linux

How the heck is that possible

docker, i don't have time to fuck around this morning

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

oh .-.

docker service scale serviceID=5

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

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

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?

Docker. That shit was too much for me when I tried it first.

I am unable to learn Docker & Kubernetes yet. It's been 3 years I am working as a backend engineer. 🥺 I don't know why I find it hard to grasp those.

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

I would like to call out the moron who decided to control docker through HTTP when the maximum time the server can take to finish the task is longer than the HTTP timeout.
If you expect things might time out, you don't use a HTTP request. You use a resource and poll it, or Websockets, or possibly SSE.
Shoehorning your API into a frame that obviously doesn't fit doesn't help anyone. Just admit that you don't know what HTTP is and use a regular TCP socket with regular pings.

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 :/

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

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

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.

Docker.

Even the getting started tutorial didn't worked correctly. It basicly ask you to run commands and fails to execute. I also banged my head to wall few times while trying to connect my dockerized application to database container.

when you mistype "docker"...

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.

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.

Have spent now about 8h trying to install nodejs, npm and less inside a Docker machine :/

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!

Just started learning Docker. The thing that seemed complex a week ago has started to unwrap the wonders it holds. Hope to make it work to ease up some of the team's deployment headache. Though there were hurdles related to firewall, company intranet, network antivirus, domain sharing etc. But managed to resolve it today.

We heard you like security so we put antivirals in your docker containers despite the fact that we made you have antivirals on your machines running the docker containers.
And we won't allow to use root just in case you want to disable the av. And we don't care you need it for the docker 😂

This is how I was played when wanted to use docker containers to avoid dealing with OPS.

Some time passes, my team is going to have independent cloud infrastructure.
Doing corporate politics is challenging...

I just woke up and on my computer screen there’s big announcement.
Github launching code package registry beta program.
Available repositories: npm, gem, mvn, docker, nuget.

Dear Docker Support,

You suck.

User with unanswered ticket for a month (and not the first time)

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...

With new terms of service docker desktop is becoming winrar - everyone use it but nobody pays for it

I deployed docker on a VPS a few weeks ago as a sort of learning experience since I haven't really worked with containers much before. Today I learned that docker doesn't like firewalls.

Or, to be more specific, it adds rules to iptables that are applied prior to ufw rules, allowing external connections that I really didn't want to allow. If I don't explicitly specify that a port is to be published only to localhost, then it punches a hole through my firewall without telling me.

Which means that all of my containers running behind an nginx reverse proxy that auto-redirects to HTTPS... were also accessible directly via HTTP.

I'm... trying to think of a reason why this kind of default behavior was a good idea, but I'm drawing a blank.

Fucking Docker.

Does anyone here uses Docker for all the environments (dev, qual, prod)?

If yes, how do you feel about it? How it is?

Okay I give up. I just don't get this docker networking stuff. I need someone to save me these sleepless nights and get on a call with me. A docker expert please. I am dying and my make believe devops engineer persona is crashing on me.

Guess who just spent the entire day before launch debugging why compose doesn't work on an ec2 instance where I DIDN"T INSTALL FUCKING DOCKER

I guess this is the key difference between me and seniors. Seniors know where to look where shit breaks because they have been breaking it for at least 5 years.

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?!

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

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?

Take a few seconds to reflect on the insane amount of human time and effort that goes into making development bearable or just possible on Windows.

A few examples: bash (MINGW & MSYS), make, symlinks, docker (docker-toolbox, WSL), Apache (W/X/LAMP)

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

If you ever wanted to, or needed to, fuck thyself over... Use the ros docker.

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

end of story

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...

WTF docker in windows
Couldn't open my virtualbox

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

"this environment is externally managed"

yes, i know it is, please fucking install it

fuck you python and fuck you docker

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

Holy pizza on ananas, docker is more amazing, than I anticipated!

Docker has changed my life.

Containers, specifically Docker and Compose. It's a beautiful model and it solves a ton of real problems, but the list of unforeseen footguns never ends.

So I can't prune a private docker registry to free up space, because there is no space left 🤦🏽‍♂️

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

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

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.

Docker isn’t always the best solution...

Docker the company is a mess.

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?

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...

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 😂

I had to argue with my lead today, to prove that docker is actually a container technology and not a CI CD pipeline -_-
That too in the team meeting.

P.S. Not much of his fault though, as ours is a mobile app development team :/

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?

me: *opens dev env using Docker*
me: *makes changes*
project: *permission error*
me: *fixes permissions*
Git: *Can't find a compatible repo*

I see a lot of comments on here about how people hate one OS versus another. Everyone has a gripe with <pick your OS>. Do devs need an OS made for them? Is Linux that OS or are we still waiting for the One True Dev OS?

I got to thinking something that is based around the Docker concept. Where every app runs in its own world. Would this be terrible?

I have no experience with docker so I don't know the technical issues. I know Docker exists on top of OSes, but could it be useful at a lower level?

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

Use docker they said...
Glorious containers they said...

Why no docker on windows 10 home ??? Why why why ???

When you're the only one who likes docker in your team and they're still insisting on using WAMP/XAMPP. Fixing docker bugs and trying to make it work. Push! This is war!

Have you ever tried using sqlite3 from npm inside a docker container?
Yeah, it doesn't build on Alpine, despite being among the most popular Linux distros thanks to Docker.

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?

FUCKING docker-for-windows, I HATE you, random freezes, "function not implemented"... the worst is that a restart works, but every 2 hours it's FUCKING UNBEARABLE FUCK YOU DOCKER CORP !

Does anyone here use docker? Curious to hear their workflows.

Then suddenly my boss wants me to handle servers and the environment etc... can anybody suggest me some site tutorials about Docker, Dockerhub, Celery and RabbitMQ?

Amazon S3 down: Cant pull any docker images >:/ ....but I wanted to update my GitLab instance. So good that I deleted the old container and image. FML

!rant. Doing some great new stuff at work to make our dev team's live easier. Finding out how to use Docker for our automated test setup, that's killing 2 birds with 1 stone.

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

Hell of a Docker

One application in c++. 4 in c# targeting Linux. Several logging places, Several configuration files , dozens of different folders to access (read/write). Many applications being called from just one that orchestrates everything.

OS is Linux. Installation is to be made inside a docker image and later placed in a container by means of several bash files and python scripts. All these are part of a legacy set of applications.

They’ve asked me to just comment out one line which took 3 days to find out because they didn’t remember where it was and in which application it was and what was in that line.

After changing it, I was asked to create a test environment which must have resemblance to the current server in production. 12 days later And many errors, headaches, problems with docker, I got it done.

Test starts and then, problems with docker volumes, network, images, docker-composer, config files and applications, started to appear.

1 month later, I still have problems and can’t run all applications at least once completely using the whole set.

Just one simple task of deploying locally some applications, which would take one or two days, is becoming a nightmare.

Conclusion: While still trying to figure out why an infinite loop was caused by some DB connection attempt in an application, I am collecting a great amount of hate for docker. It might be good for something, that’s for sure, but in my experience so far, it is far worse than any expectations I had before using it.

Lesson learned: Must run away from tasks involving that shit!

I finally got Docker to fully work...my final problem was a missing } in the nginx.conf and I needed someone else to find it, I stg i'm the worst at networking

It's quite a challenge to try and get a Docker image build as small as possible. But the worst bloat is coming from having to use CentOS 7 as a base image.

I can't believe the shitstorm that occured because someone didn't know the difference between a Docker Registry and a Docker Repository !!!

Docker is about handing over the weight of your incompetence in managing dependencies to your customer.

I wanted to create and use Docker from scratch but I have little time so I'll just use Laradock. Will just study the details of docker as create my project. And while typing this lining in a supermarket cashier I feel the urge to poop damn. Good to thing my condo is just near.

Poop = progressive object oriented programming

First time getting my hands wet with docker. Ended up fully containerizing my company's project. Never been more proud of miself.

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

Docker compose switches users but doesn't update the home directory. Both switching users and not touching envvars are very sensible default behavior, but the result is that the running service has no write access to $HOME - and many programs don't provide sensible error messages for this rather unlikely scenario.

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!

When your docker project finally runs on Linux containers after two days of debugging because Visual Studio added a \ instead of a / to docker-compose 🙄😅

So, is it a bad/good idea to run *every* service I want to use on my root server in docker containers?

Docker LAMP on CoreOS > LAMP

If you love docker, you should try css container.
