I have my reasons that Socrates once tried to understand how Docker works, because I have exactly the same feelings.
7 -
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

We are transferring our infrastructure to Google cloud and Docker. Last week one of our frontend developers tell me:
But it works without 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".12

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...

Where do i download more hours to add to my days?16 -
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.

Whatever you do, don't do this.
- a sleep for 300s to avoid full 24 hour rollover (lol)
- sleep 1d instead of cron; so at random times emails will be sent out or they won't at all
- this is a laravel project, there's a thing called task scheduling: https://laravel.com/docs/5.8/...
Git blame: https://github.com/invoiceninja/...
The actual core project docs at least tell you to setup a cron, though not via * * * * * nor task scheduling, which isn't as much of an issue though as their dogshit docker compose: https://invoice-ninja.readthedocs.io/...

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

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'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?18

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 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 all5 -
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"?9 -
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-

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 🤦♂️9 -
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 👌

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.6
-
Learn enough docker to convince my coworker that it is not the solution to EVERY problem, especially not to our problem8
-
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.9 -
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 ?!!1 -
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.3 -
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!

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 ...2 -
that moment when you have to learn Docker at work, so you convince networks teacher to do that in classes.2

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.

I got 4 raspberry pi's with docker next to me. What's the best way to orchestrate them?
Kubernetes, docker swarm, other?19 -
Is this for real?
https://docker.com/company/contact/
Docker sent me an email about some change in their service. I don't use docker and wanted to unsubscribe. There is no unsubscribe. So I reply to the email with the word "unsubscribe". It is returned immediately. Then I go to their website and the contact link. Use the form below it says.
No form. WTF?!
Docker, you close every route of communication and my only recourse to stop emails is to report it as spam?
Not impressed at all. I would not use a service that zero ways to contact. This no accountability service bullshit is a stupid trend.12 -
Why is everything slow in windows even if I have a 16GB memory? Maybe because not SSD? 😑
Slow to open in windows:

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.9 -
Today's the day, I'm learning how to use Docker for local web development. It only took ~4 years to get the gumption.14

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.4

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 system11

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.7 -

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.3

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 :@3 -
Just got our development Laravel docker image down to under 124 MB with alpine linux. The satisfaction...12

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 😍4 -

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.27 -

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.10 -
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.2 -
I’m just in love with Docker.
My enterprise finally accept to give it a try.

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 ClOuD2

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.2 -
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.17 -
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?17 -
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.2 -
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

Docker on Windows Home. Because I only used Windows and didn't want to buy pro. Switched to Linux and everything was fine.
-
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?8 -
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???10 -
Today I managed to set up a working docker project locally. Feels like I'm about to take over the world. Sooo much smoother than installing everything the normal way. And so clutter free :)

Here is my day.
1. Mac wanted to perform an update.
2. I said Okay, Do it.
3. It took sometime, I thought WTF let's force reboot.
4. Shit happened. I am unable to boot as install is corrupted.
5. Reinstalled a fresh copy. I didn't have a backup.
6. Realised that my two days of work is gone since I haven't pushed the code to github.
7. Found out that I made a docker image with all of the latest changes.
8. Now trying to decompile and rewrite the code from the jar in docker image.10 -
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...
10 -
I hate this company so much. I was tasked to write a simple program wrapped in an API. They gave me freedom of choice to use any language and technology because I said it'll be deployed in docker anyway.
Now, when they gave me the server, it's Windows Server 2016, of course, without docker installed (or even supported in any way). The access is done via TeamViewer for which I receive ID and password by calling a guy.
Oh, and everything runs as admin. "It's easier that way and we always do it like this."5 -
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...5
-
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.?

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

Hey peoples,
Have a look at my new project.
https://github.com/thosebeans/...
It's a docker container to deploy a wireguard interface.
Why would you do something like this you ask, well there's actually 2 main reasons.
1. Distributing wireguard configuration over k8s/swarm/whatever.
2. Bringing up wireguard Interfaces automatically, on systems that don't support that normally, eg. Alpinelinux.2 -
I’m currently migrating all my stuff to docker :) working quite well so far but my Webserver (caddy) is driving me crazy10

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.4 -
Last year I switched to a dedicated server with several IPv4 and IPv6 addresses. Getting Docker to direct traffic (both ingress/egress) to specific IP addresses is way more difficult than it should be. I wrote a tutorial for anyone else who's interested:
https://battlepenguin.com/tech/... -
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.12 -

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.9 -
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...5 -

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.4 -

So yesterday i upgraded the packages on my pi, docker being one of them. After that all my containers were down and couldn't be restarted. The error message said the container was already started...
Using the internet i found out other people had that problem too after upgrading to docker 18.02. I ended up removing all containers and searching the bash-history for the docker-run-commands to create new containers.
DOCKER, LISTEN UP. YOU'RE COOL AND SAVED ME A LOT OF TIME. YOU HAVE MINOR ISSUES, BUT THAT'S OK. BUT IF YOU CRASH MY CONTAINERS ONCE MORE I'LL GO CAPTAIN AHAB ON YOU.
Oh, and some more armhf-containers would be nice. WHY CAN I ONLY RUN DOCKER-REGISTRY ON AMD64-ARCHITECTURE? -
Take a few seconds to reflect on the insane amount of human time and effort that goes into making development bearable or just possible on Windows.
A few examples: bash (MINGW & MSYS), make, symlinks, docker (docker-toolbox, WSL), Apache (W/X/LAMP)1 -
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?! -
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.15

Trying to use docker for the first time, and getting nowhere. I think I'm actually unlearning how to use a computer.1

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 101 -
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.2 -
Nothing is as painful as trying to pull, build and push docker images using less than 1 mbps WiFi speed 😭2

Some time ago I was looking for materials regarding Ansible automation tool and realized that most of them suggests setting up the lab environment using virtualization (like VirtualBox). In my opinion that is not the best approach – virtual machines consume lots of resources and take some time to start/kill. So I decided to write a guide for setting up Ansible lab environment using Docker containers. Containers require significantly less resources than vm’s and can be bring up and down really quickly. Additional advantage is easy way of automating whole environment using docker-compose. You can find my guide at github: https://github.com/LMtx/... Any feedback is very welcome :)3

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.6 -

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.1 -
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.1 -

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?13 -

For me, it would be Caddy Server

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/ -

I'm following this fucking tutorial (https://blog.ssdnodes.com/blog/...) and everything goes well, I have docker running, docker compose installed properly, but when I start trying to create the docker-compose.yml and accessing the stupid site using the virtual host domain i set I can't it keep getting "503 Service Temporarily Unavailable" or "502 Bad gateway" what the hell am i doing wrong, I just want to get this working in my VM so i can move it to my damn server and have my own fucking cloud. This damn bullshit is exactly why i went into programming rather than dealing with configuring servers and bullshit like this i know it's outside my level of understanding but I really fucking want my own cloud system but I want it containerized for both isolation and learning purposes.
I have no idea what the hell i'm doing wrong and all the damn articles and links i'm reading aren't helping at all with my level of stupid not allowing me to understand what i'm doing wrong1 -
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?!??3 -
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.

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!5 -
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?6

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.1 -

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

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?7

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?5 -
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!4

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.

Yesterday at 1:20 am, my first docker image build worked.
- I develop my software (a service in a micro-service architecture) in symfony
- I push it to bitbucket, CircleCI pull the code
- builds a new docker image
- Runs phpunit test using docker exec (lxc-exec, their docker exec doesn't work)
- If the test are successful, CircleCI push the image to hub.docker.com.
Took me hours to fix all the bugs and issues with this process. I feel so proud, yet soooooooooo tired fuck sakes.
I'll publish the template for everything,
- the Dockerfile for the perfect symfony2 image IMO (and I'll create a public symfony2 image)
- The circle.yml I used etc.
Give back to the community.
I love my job.5 -
These days I now spend more time each week fucking about with Docker and VMs than I ever did when we were setting up the local environments ourselves.
I love the concept of Docker, but it seems to create more problems than it solves.2 -
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.

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.

3) Realise I'm now further back than I started.
Today has been docker.

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

Okay so.
I have a docker instance with 2 running apps. Normally one of them is just a proxy to the other one, so a http req to app0 is redirected to app1 and the same with response.
This works perfectly on bare machine, i can just rewrite the ip in the config file and it works. Now my boss decided that yeah docker is absolutely needed for this software so i have to containerize it.
Thing is docker seems to break local ips? I cant use localhost/, nor assigned ip. Is there a way i can debug this, or what should i look up??? Im lost, this is devops afaik and im far from devops.2 -

Gah, I just received this Ubuntu 18.04 VM with 8 cores and 8 gigs of ram, and since it'll be a production server both serving public and "private" networks (yes, shout at me, but projects won't be about hosting sensitive information, I wouldn't put all that on one server), and I'm struggling between my options.
Docker, or not docker?
The server's main use is to host our growing blog and install Varnish, which will hog some ram after a while. I use Laradock for my dev projets, it's really easy to develop with it, but I am unsure if it fits a production environment with performance, security and traffic load in mind :(
I read Docker has stability issues (in 2016-2017), and can bring the machine down with it, I don't know if I should just install the software (nginx, apache, percona/mysql/maria) without "containerizing" it and go for it
I'm lost xD7 -

Anyone know of a good docker backup tool?
I'm working with fairly limited space here so Im looking for a tool to allow me to backup and restore my docker instance without storing easily recreatable data.
That means that what I want to backup are:
- Container specs (inspections or the like)
- Contents of persistent, non-nfs volumes
Since the image and the contents of my nfs volumes are stored elsewhere, and my space is limited, I decided not to back them up. Same for non-persistent (unnamed) volumes since they mostly contain stuff that you don't want to recreate on every container update or recreation but can easily be recreated if needed.
The hope is that this approach should give me a pretty slim backup while still preserving everything I need to recreate my whole docker instance.
Thanks in advance!11 -
Fucking AWS Elastic Beanstalk took a week of work to get fucking mounts set up. They invented their own version of docker compose that is missing half the features so I had to work my way from hacking their scripts to include options they don't support, to restarting the whole fucking docker service on every fucking deployment and now the shit finally works.

Any one running Symfony on a Docker container in production? I currently try to migrate our dev env to a docker compose setup (from a "monolith" vagrant vm). I'm atually not stuck at a Symfony specific thing, but on a, I guess Docker specific one(?), The issue is, I need to read and write with two users to one folder (in my case the /application/var/cache folder). Since I mount my whole code into the docker container (to use an IDE on the local files), I've got a volume (not mounted to the outside world) for that folder. (As far, as good). Now this folder is owned by root and root is also the user I get when I enter the container. When I then run a cli script, that writes to this folder, every thing works (as it's run by root) and the resulting entries in the cache dir are owned by root. Trouble starts when the php fpm process tries to write stuff in there too (as it's run by www-data).
If I add `USER www-data` (or create a new user foobar and add `USER foobar`) the container exits with status 0
So I guess the question is, is anyone running an Symfony app on Docker in Prod, if so how do you solve this? Or another question would be what is the best practice to do this? Sure on dev I could just `chmod 777` the whole folder or run the php-fpm process as root, but if that thing ever goes to prod, I wouldn't sleep very well... -
After exchanging punches with laradock and docker yesterday, I was able to to find a middle ground, it promised to work and I said I would not annihilate it from my machine.
Pretty handy once it works, got now quite some docker-compose commands beaten into me, because of how many times I've up'd and down'd after re-building with different configs. -
I'm not liking docker so far. I assume it gets better later, but I've had a miserable experience using it as part of my dev environment so far. Just now I updated it and it broke my db container, so now I'm looking to either downgrade docker or fix the issue, both beings things that take time away from coding.2

Spent ages building docker containers for all our projects. All worked great and I released it. So someone added a new dependency that required an Ubuntu package to be installed but forgot to tell me. My colleague said "docker isn't very stable is it" when it didn't run due to said dependency. It's a Linux container ffs, see if you blame Virtualbox under the same circumstances you idiot

I love docker, but when it's not working and you're having WSL permission issues on Windows, it is a pain in the ass!
I have no clue exactly why, but I tried debugging and circumventing the same problem for hours, if not days:
Docker keeps crashing due to "unexpected WSL error".
The only thing that seemed to help (sometimes, at least) was to Uninstall Docker, Reboot, Disable all Windows Feature flags that docker needs, rebooting again, enabling them flags again, rebooting, and then installing docker again.. aaaand voilá here it is again, while I almost lost all my nerves >:d
This only happens on my work-computer, which seems to not properly be connected to the ActiveDirectory Domain or something like that, which renders the whole computer basically useless and I can't do anything about it (for example, install a proper os called linux) since IT blocked BIOS access *silent cries of pain*

Decide to move to docker for windows from toolbox. Worked well until vpn/s-tunnel all crapped out.
Found out about hyperv, default ethernet, HNS, windows DNS etc etc getting confused.
Removed docker and hyper v, back to working again.
Interface index for adapter selection , really ? -
I've been using Docker for almost two years now, I've to say it's a super powerful tool and allow easy environments deploys, but I keep questioning why people use Docker in production? Even in the place I work they do and they can't explain it very well
I mean, you are creating a container that hosts services in a computer that already have services running, being one of these services the Docker daemon, all this shit doesn't add a lot of overhead to the application?
I mean, it's not better to just install python in Ubuntu instead installing Docker in Ubuntu, run the Docker daemon, start a container with other services and now I run python?
Just saying6 -
Been watching lots of videos about Docker lately, yet I still can't wrap my head around it. Especially that I'm just new to web development.11

stupid docker creators. Why the fuck when something does not work it does no show errors. I had so much anger till idea came to head to ask on google does docker has logs and found it has - docker logs command. And I saw fucking errors and then I knew by them what to fix. Idiots, hide errors when runing docker-compose up, what are they smoking when creating docker.
And even after docker-compose up it showed done !! Done sounds as everthing went without fucking errrors!!!! But when running docker ps there was no such container! Because when running it - it was giving errors.13 -
Is there a way to run docker and virtualbox at the same time? (in windows) Because Docker uses hyperv..13
-
when docker desktop lies to you it updated when you looked to update to latest weeks ago
so you try again and realize there's no fucking progress bar to get any sense of progress -
WSL seems really cool from what i've been toying with it. WSL2 seems like it'll be even better and the integration with docker(another thing i'm toying with) looks interesting. as far as i can find though it's only on windows insider for now, and I don't like having telemetry on my main machine.
So i spent a good chuck of my day just setting up Hyper-v, learning about nested virtualization (so docker will work), setting up a win10pro vm, and i'm now in the process of setting this up to be a virtualized dev machine (not gonna be a one use only system cause i spent way too long on this shit) and setting up docker and wsl
I don't know much about docker or WSL beyond just some random stuff i've learned to toy with to simplify some things i do. but maybe this will give me a cool way to actively learn more about them and maybe use them as more than just boredom toys3 -
[what happens if a Linux user wants to try a game out]
I've created a Docker image that uses Wine for playing Sonic Utopia Demo.
In case you don't know, it's a experimental game that shows how Sonic games should have been from the beginning. (not the official description) I highly recommend playing it.

How much time will it take to learn docker?
I want to containerize python deep learning models, which you tensorflow and mxnet.7 -
Java and scala development:Intellij+gradle
Git: Gitlab + gitkracken
APIs: postman, insomnia
Scripted languages (most favourite to least ): Brackets(#1), Sublime, vscode, Atom
Others: Docker + Portainer, Visual studio (when playing with C#), geany for light works -
hey there
recently I've been thinking about a good way to deploy mass amounts of containers on kubernetes, but before I just go with docker, I want to learn about some alternatives
what are some other container softwares you guys use?2 -
I suppose the modern equivalent to waiting around code compiling is building the bloody Docker images. Vastly exacerbated by the requirement of an X86 image on ARM hardware.
FML 🙃1 -
Have you ever stuck between user permissions, docker, Jenkins and Linux?
Running a docker with a particular user that doesn't have permission to folder inside container. user permissions should be same on host and inside container. When I did that container user does have permission of certain file on the host.
Successfully wasted my day on fucking things.
I have to again start with this tomorrow wish me a luck.4 -
Docker gurus: I am not familiar with docker, any immediate problems stand out about the idea of trying to make customized vim into a redeployable docker image for easy portable usage?
Thought I might side step having to save config and reinstall stuff (still got to pimp it out the first time)11 -
Not sure if this is somehow standard but have a new dev process we need to use to deploy a Docker image to an Openshift container.
(Is an container one node/vm or could be many?)
In the Jenkins build it seems the files are copied to in Docker image.
But they aren't copied to the container/OPENSHIFT deployment image. There's something mentioned about config map but not sure how that's related to file copy...10 -
I just want to say that I am extremely irritated that the question of which webserver to use to serve static files inside a docker container has become political.12

I’m trying to add caching functionality in my scalable spark cluster on Docker. I am able to add redis to my Docker container, but that doesn’t add redis-CLI or any other useful tools that I need. And there are some redis-cache projects on PyPi, but they are very old and not compatible with python3.5

Setting up new version of provided software with docker. Which is new to me - heard about it but never used it before. Took me a hour.
Waiting for license key: more than 1.5h now.3 -
What do the new ARM macbooks mean for developers who don’t exclusively work with Apple platforms? Will they be able to run all the current OSX software like IDEs and Docker?5
-
So, what happened to infrakit/deploykit? They ditched docker machine and I've missed the whole story.2

Django project in a docker container in an ec2 instance of my aws vpc... i did use elastic beanstalk though, but needed to let my media files be uploaded to S3... couldn't figure it out yet...

My work are tight bastards. Docker recently started charging for Docker Desktop and are refusing to pay for SIX licenses.
The amount of money pissed down the drain trying to get mulitpass to work instead has far outweighed the cost of licenses.
No chance of a serious raise in six months if that's how they're playing it -
for some fucked up reason nextjs would not run on my apple silicon machine
had to use nvm, tried node version 14, 20 then back to 16
then i thought of using docker
pretty smooth so far
will be using docker from now on1 -
Disclaimer: I am relatively new to this. Feel free to use a tone you'd otherwise use to explain to a 10yr old.
I am trying to run a rails app on docker. I came across permission errors while I trying to edit some of the files. After a couple of searches, I found out it is because docker, by default, creates files as root. I have been reading for a while now and I can't, for the life of me seem to understand how to implement USER instruction as recommended in the docker documentation.
Here's a link to my dockerfile https://github.com/Melvin1Atieno/....2 -
So I ran a yarn build for a vuejs project in a php7.4 docker container on a raspberry pi 3.
Wasn't as fun as I thought it to be.6 -
Does someone know how to set up plugins for airflow?
In particular do you know how I set the PYTHONPATH env var for the docker container to Import my custom airflow plugin? -
Since a friend of mine owns a domain for an open-source project and manages pretty much everything, including dealing with a db for registered accounts, I'm currently not really able to help when it comes to UI/UX things and frontend, besides the "main editor", which is like the core functionality of the project. I would like to set up smth like docker (on Windows 10 home, which is already not suitable, great start🤦) for some kind of pseudo-db all inclusive functionality thingy to be able to run a working example locally. Also a goal would be to switch to Typescript, include testing, to use webpack and to automate as much as possible.
Sad part is, I don't even know where to start and I'm also 100% sure that I will do almost everything wrong from research to implementation.😐1 -
I need to run wordpress on a Windows server or Windows 10 to be used for a medium sized WooCommerce site for a reason I don't want to state. What is the best way to do this. My best options seem to be :-
Using IIS
Docker with caddy
Linux vm with or without docker9 -
Why the fuck doesn't Docker mount a volume unless the container is privileged? My host is not even Linux. What sort of privilege does a Linux container obtain on Windows when executed with --privileged?
If I was ten years younger I'd start writing my own wrapper for CIFS... Too old to care these days... Gen Z kids can find a way to run a privileged Docker container on AKS for me.1 -
Its annoying. Spent again hour trying to make run my symfony app with docker - and fucking does not work and is not clear why. Why this fucking docker is so unclear? Like does not see autoload.php file but I see it installed. Idiot docker.5

I have two coworkers that discuss every day for hours about anything.
Past month they were discussing about Docker Swarm x Kubernetes and it’s impossible to work without headphones and loud music. -
I spend Way too much time on docker, and this week, rancher !
But totally worth it, it's fun to learn and pretty usefull ^^ -
What's the point of Docker Hub's automated builds? It's often faster to just set up a CI build to do the same thing, and it's the same amount of effort to get going.
It's way too damn slow. -
If someone can shed some light on this behavior, would be appreciated:
I am running a couple of docker containers with lighttpd on my server (lighttpd is also installed on the host server for reverse proxy). Now whenever I kill lighttpd on my host server it also kills ALL the running lighttpd instances in my docker containers. Isn't docker supposed to be, idk, CONTAINERIZED?2 -
My docker container does not have internet access. I tried so many things from multiple places but unable to resolve the issue.
Please help anyone has faced this problem.
Specifications - CentOS 7, docker ce 19.3.016 -
Guys do you use strictly Docker or an alternative, I installed Docker desktop, i tried to install nextcloud-all-in-one but i was getting errors and never got success even through the gui interface, is it a better idea to install it in a docker container or not? and if there is way more simpler alternative then what are those choices?1

Laravel docker ports configuration sucks. There is no fucking documentation in fucking laravel docs how how to fucking configure ports. I have set wrong port, wrong host with my docker setup and it was just giving fucking stupid error where lot of stackoverflow solutions do not help. FInnaly I found the solution here https://stackoverflow.com/questions...
which finally helped. So the host needed to set to the mysql instead of fucking localhost - I had found this in another SO answer but it was not enough. How the fuck can I know. Why it is not written in documentation. https://laravel.com/docs/8.x/...
And then port - it was needed 3306 - how the fuck could I know that I need it instead of 3000 which I have set in docker setup? Wtf.
Finnally when I made query "laravel docker what mysql port to use"
then I found this stackoverflow answer. Why need to make things so hard?
