Modern web development is fucked. Just absolutely, totally screwed up.

I want to create a simple to do list web app. Look for a tutorial: "OK guys, this is really easy, it just takes five minutes."

First step, install these:
- Git
- NPM
- NodeJS
- Express
- MongoDB
- Docker
- React

Second step, npm install about one million modules. Don't question what they do or why they're there.

Before you know it, six hours have passed and you've got a code base of 3GB and you haven't even _started_ on your app.

FUCK that shit! I can create this web app with Internet Explorer and Notepad.

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. 😫

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

This is so accurate...

(From random twitter post)

Minecraft running in docker. Yessir.

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

My every day life

Docker is starting to look like windows...

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"

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

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

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".

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

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

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

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!!

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

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

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.

WTF?

f.lux is alternative to docker ????

how? why? what?

I tried to build an application in a container, but the build failed with 54 warnings and 86 errors.

My coworker watched the build fail from behind me, and jokingly said "Well... have fun going through all that".

I told him to wait just a second.

I switched out the image for the build step with a slightly altered one.
Build fails with one error.

Coworker just stares at the screen with his mouth open.

I'm starting to appreciate Docker now.

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

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

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!

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

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.

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.

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.

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.

New dev prefers mariadb over postgresql, which is okay.

But his main reason is 'the smaller docker image'

What an argument, wtf

how docker was born...

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'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

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

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 😡

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...

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

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

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

dicker-compose up

But why??

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

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

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

!rant

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

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.

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!

:)

A Docker build times out and returns "unknown blob"

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?

Docker

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

Oh crap. Please no. Anything but that.

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!

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.

Docker + windows containers + Windows 10 = fucking nightmare 😵

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.

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

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*

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.

Docker.

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

No Docker Hub. That's wrong.

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.

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...

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

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

Docker, what the fuck are you storing?

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.

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

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

DOCKER ON WINDOWS</rant>

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

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

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

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

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

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.

KMS

I think I'm starting to like Docker.

What's your experiences with Docker?

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.

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.

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.

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.

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

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.

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

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.

I feel like an idiot... I just realized why my builds were failing.
My entrypoint was setup as to not overwrite a specific file if it was already there. The problem is, the said file is auto-generated, and I need a different configuration for it to work properly in docker. But I forgot this, and the result was a failing build, plus me scratching my head for a few hours. :(

Is there room for docker in an agency environment? Or should it be utilized solely for larger scale application deployment?

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

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

oh .-.

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

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

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.

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?

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.

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 :)

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

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

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.

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

In Swedish the phrase "Jag har lekt med docker hela dagen!" is just one letter from meaning "I have been playing with dolls all day!". This is a pointless observation but I illustrates how happy I am after a whole day of configuring a project in docker. With good progress and learning. Not that I enjoyed playing with dolls as a kid but with with Airfix model airplanes. But I am sure the joy is much the same.

So apparently Docker exposes all the forwarded ports on *all* the interfaces, making all running containers available to the entire internet BY DEFAULT.
I have a question:
WHY???

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.

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. 😎

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

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.

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!

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

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.

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.

!rant

Docker has changed my life.

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.

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...

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.

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.

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

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 :/

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.

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?!

Docker isn’t always the best solution...

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 :/

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...

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

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

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

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

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

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?

WTF docker in windows
Couldn't open my virtualbox

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?

Dear Docker Support,

You suck.

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

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.

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.

After two weeks of struggling with Docker, I can confidently say, this is the worst shit I've ever worked with.

$ php bin/console make:migration
ERROR: php_network_getaddresses: getaddrinfo failed: Name or service not known

Well let's try again...

$ php bin/console make:migration
ERROR: Connection refused

Different error messages for the same commands?! FUCK YOU!!!

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

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...

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!

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....

A good Day to learn something new!

Docker! I'm coming!

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!

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 y u no fucking start...

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.

Holy fucking shit! Almost 5 hours I was trying to make Docker container with PHP 5.4 to work, because I couldnt fucking connect to my fucking localhost DB. After 5 fucking hours of desperation I tried to create DB on my hosting and... IT FUCKING WORKS LIKE CHARM. IF I KNEW SOONER!!!

I suck at DevOps at least as hard as I'm good at front-end/UX. I found out as a result of the local job market starting to get needy for 'full-stack'. Stuck for 2 days on setting up a Docker/ Dockerhub/ DigitalOcean/ Bitbucket pipeline with Nginx/ Node/ MongoDB Cloud & Webpack/ React.

*Sigh*

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...

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

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

Docker the company is a mess.

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 😂

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?

Okay... I am more than annoyed. 😵😵😵 I've been trying for days to get 2 small dockerized Spring REST-Services to communicate with each other. Without docker the services work fine with each other. I've tried many tutorials, examples, hints online and so on and none works or does something else. There is so much deprecated stuff or huge tutorials where I have to install 1000 other useless things. I kinda feel like this Microservice Stuff is a myth or I'm just stupid. Even my partner has no clue.

Duck! this sloppy whiny winnfsd.

Yay! Let's use state of the art Docker with a VirtualBox VM on Windows10.

Don't get me wrong.
The Docker containers in this VM doing a great job on performance.

But in the very moment a Docker container uses a mounted folder via the windows network filesystem, all hell is breaking loose.

Building a vendor folder using a composer Docker image with 84 Packages takes about 15 seconds when cache has been warmed up.

The same Docker command pointing on a folder mounted to Windows Filesystem with warmed up cache takes about 10 Minutes!@&&@""+&

And what is the duckin' reason for this delay?
Because every transfer of a teeny tiny file has to establish a connection to fat ass Windows OS and has to pass it's glorious "security" layer.

DUCK it!
For real.

I currently working on a shell script which builds the whole vendor folder on a volume on Docker VM.
After completion, the shell script will compress the folder to one file.
This one file will be transferred over this god damned network filesystem.
Finally the script will unpack the compressed vendor folder in it's destination folder.

*sigh*
What year is it?!??

Trying to port legacy application onto docker. Please kill me

Last weekend I was working on a small project for a friend of mine: a dockerized webapp, plus API backend and DB. I had some problems with the installation on the vps and had to try out different images and never really did a complete setup of my usual dotfiles. Got it running on an Ubuntu distro. Everything great.
It was the first release so I still had to check that every configuration worked ok, like letsencrypt companion container, the reverse proxy and all that stuff, so I decided to clone the whole project on the server tho make the changes there and then commit them from there.
Docker compose, 10 lines of code, change the hosts and password. Boom everything working. Great... Except for the images in the webapp.

WTF? Check the repo, here they are, all ok. I try different build tactics. Nothing. Even building the app on another docker always the same. Checked browser cache, all the correct ports are open. I even though that maybe react was still using some weird websocket I didn't know, but no.
Damn, I spent 5 hours checking why the f*** the server wouldn't make it out.

Then, finally, the realization...

I didn't install the f******* git-lfs plugin and all I was working with were stupid symbolics links! Webpack never even throw an error for any of the stupid images and the browser would only show a corrupted image, when decoding the base64 string.

Literally the solution took 5 minutes.
F*** changes on production, now I do everything on a fully automated CI.

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

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

Currently writing a long-ass new issue to the Docker/CLI repository, to tell them that their online documentation for the manifests is absolute garbage. I mean, a documentation is supposed to tell you how to run commands, not something like "Yeah you try it and maybe it'll work. No it's not the good format, you dumb fuck. Nice, bro, but if you check what changed... That's right, nothing changed. At all. For no reason. Keep trying, it's fun!"

The tech adoption curve

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?

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

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?

So, i'm trying to get linkr (a pretty cool short link service) to work in a docker container since 4 hours now to host it on my server. There is no official container because it needs a working database connection and stuff during installation which can only be done via console and (for whatever reason I couldn't find out yet) need to be done while building the container. The problem is, I can't connect it to the database while building the container so there is no database during installation to create tables and stuff and the build will fail. ARGH.
Why the hell would you do this????? Theyre actually saying in their readme there is no dockerfile because the config options are specific to your configuration...?!?!
The thing is entirely written in python, so reading and parsing configfiles on the fly should not really be a problem.

Of course I could ssh into the container and run the installation script but that's not the point.

Docker is not about being lazy.
It's about portability.
Maybe I don't want to bloat my server with your 39579372639 npm dependencies? Or I don't want to install a freakin apache, because I have every other site on nginx and therefore wouldn't work with apache.

AAAAAAAARRRRRRGGHHGGGGG

in the end, I'm probably going to modify the thing to install tables when running the container and giving the first user admin rights instead of prompting to enter credentials for a new admin user.
And yet I didn't even speak python.

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
