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

Alright, you win. I have to admit.

I like docker.

We are transferring our infrastructure to Google cloud and Docker. Last week one of our frontend developers tell me:
But it works without Docker!

enabling firewall on a vps to secure my docker containers and forgetting to add openssh to allowed list --> ssh blocked 😃🔫

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...

WHEN DOCKER IMAGE NUMBER TWENTY-MOTHERFUCKING-TRILLION FAILS TO COMPILE /RENDER/WHAT-THE-FUCK-EVER THE GODDAMN DATA WITHOUT PROVIDING SUFFICIENT ERROR/HOWEVER-YOU-FUCKING-CALL-IT DEBUGGING INFORMATION.

I'M DONE. I. AM. SO. FUCKING. DONE.

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

First time seeing software charging me to not update from Docker

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...

Trying to setup a local Overpass API and Nominatim server (OpenStreetMaps data stuff).

The docker overpass image has been downloading a 38gb file for a little more than an hour now and it's coming closer and closer...

3..........
2............
1...............

100% YEAAAA.......

*docker continues to initiate the download of a new file*
"Hmm this can't be THAT bi......"

25gb

D:

Let's wait yet again..... I was so excited :(

WTF?

f.lux is alternative to docker ????

how? why? what?

Since I have started using Docker, I try to build even my local development environments around Docker...

DOCKER ALL THE THINGS!

There's so many cool technologies too look into now a days, but so little time.
-docker
-laravel
-.net
-react
-es6/es7
-elasticsearch
-redis
-unit testing

Where do i download more hours to add to my days?

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.

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.

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`

"Let's create a docker-swarm cluster thingy for this application with horizontal scaling to learn docker and run this application better!"

This stuff is so overwhelming and I don't understand half of how to possibly set this up 😅

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!

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”

I like to come up with superhero names for my docker containers. That makes me feel like the Uber-villain when I run "docker kill elasticman"

Sick leave mail...

Hi team,

I don't feel good and gotta take a sick leave today to see a docker.

Best,
Tammy

Might be nothing for others, but I finally published my Vue website with the following setup:
1. Vue inside docker
2. Nodejs API inside docker
3. MongoDB inside docker
4. Nginx as reverse proxy
5. Let's Encrypt

6. NO I WILL NOT SHARE THE LINK, don't want to be hacked lol and it is for personal use only.

But I'd love to thank devRant members who have helped me reach this point, two months ago I was a complete noob in Vue and a beginner in NodeJs services, now I have my own todo website customized for my needs.
Thank you :)

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'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?

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...

"here s your new server"
*Suse 12*
*Fs Layout is a mess*
*Ext3 everywhere*
*Docker is poorly supported, but supposed to be the heart of the server*
Can i go home please?

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

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!!!!"

Me: We need to allow the team in the newly acquired subsidiary to access our docker image repositories.
Sec Guy: Why?
Me: So they can run our very expensive AI models that we have prepared onto container images.
Sec Guy: There is a ban on sharing cloud resources with the acquired companies.
Me: So how we're supposed to share artifacts?!?
Sec Guy: Can't you just email them the docker files?
Me: Those images contain expensively trained AI models. You can't rebuild it from the docker files.
Sec Guy: Can't you email the images themselves?
Me: Those are a few gigabytes each. Won't fit in an email and won't even fit the Google drive / onedrive / Dropbox single file size limit.
Sec Guy: Can't you store them in a object storage like S3/GCS/Azure storage?
Me: Sure
Proceed to do that.
Can't give access to the storage for shit.
Call the sec guy
Me: I need to share this cloud storage directory.
Sec Guy (with aparent amnesia): Why?
Me: I just told you! So they can access our AI docker images!
Sec Guy: There is a ban on sharing cloud resources with the acquired companies.
Me: Goes insane

Is there a law or something that you must attempt several alternative methods before the sec people will realize that they are the problem?!?! I mean, frankly, one can get an executable artifact by fucking email and run it but can't pull it from a private docker registry? Why the fuck would their call it "security"?

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.

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 🤦‍♂️

A lot of docker containers.

I often have to use docker containers while I don't understand it as well yet and quite some containers literally come with zero documentation or bad docs.

This both as for how to set the containers up and how to debug stuff.

This is one of the big reasons why I'm not as big of a fan of docker yet.

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

She is my "dummy test" for me to make sure that I explain things clearly enough so that anyone could understand. So far, I taught her how Docker, Ansible and CSS work 👌

Our local cyber security team has asked all to remove docker from their laptops, reason they can't track them

Most of our stack is aws fargate with nodejs and java springboot

Developers = wtf ?!!

Installing my company's microsystems architecture to run locally is a pita because it is 60 GB of docker containers. With my 256 GB Macbook, that's a scaling problem for the years to come.

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

Oh crap. Please no. Anything but that.

!rant

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

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

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 :)

I really like Docker. I think that’s the best thing that happened in the dev field for years. Easy shipping and installation of software without messing up dependencies to other software.

You mother fucking piece of shit.

Whoever taught you programming should be removed from history.

And whatever form of intelligence you claim to possess, let me assure you: breathing is the limit of it.

--

Some of the projects I'm working on are really the epitome of "YOLO let's turn the poopomat machine on in diarrhea mode".

The worst: I cannot really give examples.

I've seen the last days everything.

(bash scripting, docker, services like nginx /haproxy/...)

Eval as an template generator in bash...

Declaring an whole environment in an Dockerfile, that should never be used as it is only necessary for building... But not checking if an env file is provided, so the whole thing can blow up spectacularly.

A nearly 1k long bash calculator for system limits, reading out all kinds of stuff from /proc and /sys, seemingly partially stolen from NGINX Docker.

Declaring and starting an own DNS Server to bypass the Docker DNS service inside an docker container.

Mkfifo fun for creating several stdout and stderrs for seemingly no reason...

Actively not using bash, instead of creating shell only functions to emulate bash...

I could go on.

But really. I'm getting too old for this shit.

Two weeks of my life! All of this is on a win10 host with docker for windows. This is Docker running openvpn, and docker running Firefox in another container sharing VPN access from first container and also opens an x11 window port for Firefox GUI. Then x11 window server on Windows host to receive GUI. So left is firefox clearnet running native, right is Firefox over vpn in all containers, simultaneously.

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 ...

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

osu-web devs: we use PHP because it just works *stabs in vagrant*

My webdev friend + my crazy ASP.NET Friend: hold my beer

*proceeds to refactor everything to ASP.NET and stabs in Docker*

welp, thats enough social interaction for today

what the fuck is wrong with boomer professors ?? I enrolled in a front-end development elective at my uni in hopes to just brush up on some little things I may have missed on my self taught education.

this class has been an absolute tragedy. he spends about 1 hr each class trying to figure out how to configure docker... FOR A PROJECT THAT IS JUST BARE HTML CSS JS. WHY??? he is so adamant that we use DOCKER for this class. I don't understand why.

most of the students are BRAND NEW to front end development and know Jack shit. and here this professor is insisting on nuancing the class with docker. it makes absolutely no sense.

Why is everything slow in windows even if I have a 16GB memory? Maybe because not SSD? 😑

Slow to open in windows:
- Docker, Postman, etc

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 thought Docker was supposed to make life easier.... Instead, it's giving me imposter syndrome all over again because I can't seem to wrap my fucking mind around it.

Docker decided to name a container I ran "Cranky_Torvalds" 🤘🤪🤘
This is just perfect

So I use Docker, Gogs, Traefik and Portainer. Maybe it's time to start learning Golang.

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

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

Docker swarm. All i want is a 'zero-downtime' system and everytime i try to set it up there's three damn things missing. Load balencer, service updater, and a good distributed storage. I finally got pissed off and am working on those but fuck it's been how fucking long docker has been out why the hell somebody else hasn't done this yet.

Spent 30 minutes searching for openVPN on my VPS to end up remembering I have it as a docker container and not installed directly on the system :\

Today's the day, I'm learning how to use Docker for local web development. It only took ~4 years to get the gumption.

OH MY GOD DOCKER I JUST WANT NODE TO CONNECT TO THE DAMN MYSQL CONTAINER!

its probably easy but jesus there is so much weird documentation to go through and hope something works...

I think I'm starting to like Docker.

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.

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 😍

i had to learn docker and graphql in 3 days

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.

School group project: Pipeline is done, everything deploys automatically, microservices work in development, https everywhere, Docker is bae, everything works perfectly

Now I have to work on frontend stuff ;_;

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

Docker has taken out 2 of our (6) on prem servers.

It's forked 65k processes to run a health check on 4 stacks...

How's your day going?

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 :@

Golang's standard command line parsing library suuuucckkkkssss. But who the fuck writes command line apps any more? Everything has to be a fucking asynchronous daemon in a docker container orchestrated by kuberwhateverthefuck running in the ClOuD

Upgraded my vpn server to latest ubuntu, forgot that docker has not yet provided support for it T_T

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?

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.

Sad story:
SSHd to a vultr server, downloaded MongoDB docker (approx 170MB) download and extracting 70% of the image was done faster than me navigating from devRan notifs page, to devRant feed page, I need a new internet plan T_T

Anyone who says 'Docker is easy" should burn in hell.

Sure, It took me 5 minutes to run my project in docker container

Took another 25 to run multipl;e comntainers via compose

Now, 3 hours later, can't run compose from multiple Visual Studio solutions. Says "Pull failed"

No doc. No examples. No nothing.

I'll try for another hour or so, if not, fuck that docker shit. I'll go to Service fabric.

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

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.

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.

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.

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

FML

🤡

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...

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.

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.

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 :)

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???

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 on Windows Home. Because I only used Windows and didn't want to buy pro. Switched to Linux and everything was fine.

Chef- why you be so difficult to install? You make me miss 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.

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

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

I’m currently migrating all my stuff to docker :) working quite well so far but my Webserver (caddy) is driving me crazy

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 :/

I love nginx' docker container, but it always takes me 2 minutest to remember that an idle nginx container does NOT output any logs

So here's my dumbass staring at the log output, thinking something's wrong

Tired of having to swap around projects all the time, so I'ma give Docker some love <3

Docker.
Tried very hard to like it.
Went through every possible option of making it work properly in every situation.
Ever since the licensing bullshit it has really gone to shit.

So I'm trying out docker and see how I can make use of it, current setup:
1. Ubuntu on VM and Mac for Asp.Net core development
2. Windiws for MS only stuff like SQL Server
3. Ubuntu Server on VM and is running docker images: MS image for SQL and Ms image for dinner core.

What I did so far one script which will handle updating SQL Server database on windows with the changes done on docker SQL image
Then publish website from Mac or Ubuntu to docker image. I have yet to find a way to execute scripts remotely on a docker image using bash script from a remote

What should I do next? And for home setup go for Ubuntu server or CentOS? Any recommended packages for server administration? Workflow ..etc.?

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.

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?

I love it when docker just decides to kill my containers 🤪🤪🤪

I will never rant enough about Windows. It is so aged. I have 6TB of storage, 2 SSD of 1To and 1 HDD of 6TB

But windows doesn’t care, it will pack everything in the same disk in this damned AppData no matter where you install your softwares, making main disk full.

Wanted to build a rather big docker image, but yeah, because I guess that the guys from Docker have other things to do than caring of a 90s OS with a fancy UI, they use an emulated ext4 file system, it filled my disk, Docker is crashing because of that, letting me no other choice than removing the emulated disk.

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

Mid handover - my Gmail (GApps) access stops working.

FUDGE NUTS...

Attempting to run a Docker (ECS) deploy from AWS.

ERROR
User: arn:aws:iam::XXXYYYZZZ:user/foobar@screwed.com is not authorized to perform: ecr:DescribeRepositories on resource: *

Hilarious.

As a fresh graduate in Hong Kong, majoring in information engineering. I still don't know how to explain what my major related to... And don't even expect me to know any node , react , angular, docker, etc...

Not moving to docker eariler and waiting for it to mature. Its mature now and i still have to write the same things as i would have 2 years ago

Finally found a way to deploy my Docker image to my VPS with nothing else than GitlabCI. My CI/CD system will soon be perfect.

[ Heavy breathing ]

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.

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 😤😤😤😤😤😤😤

With a large caffeine high and an all day techno stream, I’ve managed to finally “get” docker after 4 years working with it

I was totally unaware of the world of configurations!

Ruby versions, Cocoa Pods versions, Manifest files, Docker files, podspec.yaml, then .lock variants... Jesus Christ and Moohamed...

You need to be devops just to be a programmer

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.

Spent two hours trying to figure out why I couldn't get SSH agent forwarding working in Docker. Turns out I was never granted access to that other obscure GitHub organization we use. 🤦‍♂️

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

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...

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.

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.

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)

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

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

Life is like a box of docker, you don't know which one is going to break.
My name is docker, docker cloud!!!

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

!rant

Try to get Anbox running in a docker container.
May the Force be with me.

Ask me to build a backend system with AWS services, docker containers and ExpressJS/Laravel, I am down with that.

Ask me to move an image to the center of a div, I am tapping out.

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...

Time to get going properly with ansible, consul and docker swarm.

Idea is first to convert tinc to a container, which automatically sets itself up based on previous consul announced tinc nodes.

Consul to keep track of all the nodes with prometheus too and hopefully auto attach to grafana.

Ansible to set up new nodes right with DO API, announce to consul, pull docker images and join the docker swarm master.

A good Day to learn something new!

Docker! I'm coming!

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?!

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?

Pure java person put on a project running micro services on docker.. Cannot understand a thing but good developer ego not letting me ask some1 to explain me.. Weird situation 😅😅😅

Last month, I learnt Docker via the 1 hour crash course of the YouTube video.

Now, I don't remember all the content of that video which made me think that I should start making notes.

I understand the basic fundamentals of the Contanarization and a couple of commands.
But I still feel like I'm lacking the whole picture of the docker.

I wonder what other devs do to learn new tech and also about note taking habit for revisions.

Nothing is as painful as trying to pull, build and push docker images using less than 1 mbps WiFi speed 😭

I just spent about 30h desperately trying to figure out why my Qradar API queries were not working while running in docker, but somehow worked when running locally. I was just minimally stressed because it's my bachelor thesis, which I need to turn in in 3 weeks and this basically nuked my whole planning.
So apparently docker requires you to set your own timezone, so my API queries were always querying data from an hour early, when the requested data did not exist yet....
It's 3PM and I need a drink, or maybe 10

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

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

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

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

Starting to work with merge requests, unit testing, a shitload of different environments, Docker, Jira and stuff like that can be overwhelming for the first time, but it sure feels good to finally sit in the table with the big boys

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.

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

Just spent a lot of time on custom building an Ubuntu docker container, and forgot to save the image before I accidentally reset the whole thing to blank

Fuck ruby. I've spent less time learning the ecosystems of java, golang, node, and docker combined compared to the shit ruby is flinging at me like some sort of deranged baboon

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

Setting up docker is so fucking complicated. Theres like a trillion combinations of something going wrong. I have never been able to setup docker right on the first try. Theres always some fucking compilation failure or corrupted images and containers. The thought of using docker frightens me for this reason. But still makes me want to use it because once it's set up it makes dev life 200x easier

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....

!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.

Got a new server that is mainly going to be used for development tools: Gitlab, Docker, and others. Anyone here have any suggestions on how to set it up? Should we virtualize it or use Docker on top of a light OS light Core OS?

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

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?

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?

Me: LOL Docker Desktop asking to update all the time! I'm fine.

-moments later after a reboot-

Also Me: Why is docker always starting up so wonky these days ....

Probably should update I guess ;)

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

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!

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?

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

I love containerization platforms....for eg. Docker....You can do whatever you want to do in the container..., literally blast it....and whamm!! ....within a minute or two, you can recreate it

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?!??

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.

Every fucking three days a group called ITO pushes new software to our development machines and fucks them all up. Gooosfraba.

I then spend two days fixing said fucked up machines and can develop code for one day before the cycle repeats. Usually they fuck up docker so don’t tell me docker is the answer.

Going to try Vagrant now. Spent half of the day deciding which one to start with; Docker or Vagrant. 😯
As Vagrant seems less fancier than Docker, gonna start with that. 😄

For me, it would be Caddy Server

Discovered it while running some researches around GoLang, where I could see that it was really useful when used with Hugo Framework.

It took me something like 10mn to configure it to run (I couldn't believe only 2 lines would make my things work), and 5 more to make it run with Docker and Traefik (another good open source project that I now use everyday).

Now all my projects where I use Docker have Caddy included o/

What's devRant getting into this weekend?

I think I'm going to jump back on algorithms review and finish this deep dive into docker.

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.

So Docker is pretty amazing, but I'm finding myself immensely frustrated at all the stupid shit devs do with their Dockfiles and stacks. Like the surprise of finding out Jenkins clients aren't setup for SSH or stacks opening up 5 public ports when all they really need are a bunch of private ports. Or how Jenkins deployments expect crazy tags so I have to add some really stupid tags to my own nodes.

How is it so hard to comprehend Docker for devs? It's so easy that I'm in utter bliss when I stop trying to use 3rd party stacks.

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

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

PISSED.

Fucking Docker, for no fucking reason (no updates, no changes, etc), I tried booting it up following the morning ritual, and nope, ERR_EMPTY_RESPONSE when connecting to my current project (means I managed to connect but for some reason no data is sent). Nginx container doesn't yell about anything.

Everything around works. Accessing the container works. Even pinging my dev domain works. Why the fuck suddenly fucking Docker just **stops**?!

Restarted Hyper-V, updated laradock, recreated containers, disabled AcrylicDNS. NOPE.

"Fuck you Phlisg, I'm not in the mood today" <lunatic Docker is lunatic>

ARG.

If i use kubernetes that means i don't have to use docker and docker compose. Right? Kubernetes is like docker but on steroids?

I seem to have built my app and tagged it as caddy:alpine by accident. How does this happen and why does Docker allow you to override images without specifying something as obvious as --override-registry-image on the command line?

Think I spent 3 hours today trying to get docker to watch my files

I have concluded that, probably, this feature is too new and buggy and they shouldn't have released it

Maybe my googlefu sucks now idk

Also can the docker docs just get to the point, why do I have to click like 12 links deep and why are there multiple pages saying the same thing. Is Google behind this? Because this reminds me of Google's terrible documentation.

Finished making a snake game in PDF. The standard is deprecated and every other function was broken. Even getting Docker to work in Windows didn't feel as good.

Do any of you have any good resources at hand on good ways of managing Docker deploys? I don't want to use something as overkill as Kubernetes. In the end I want to be able to spin up the application on a $5 DigitalOcean droplet if need be.

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

Thanks

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!

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

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

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