Docker Guide

[@MoAbualruz]

Chris I have watched your videos since years, this is my 1st time commenting today, I just want to say thank you for sharing the knowledge, and doing exciting projects.

[@siljeff2708]

Docker on my NAS is only used for Jellyfin and Pi-hole, and I would love to get more use out of it. This is the perfect video for a Friday!

[@cheebadigga4092]

All distros except Debian Buster (version 18) have a fairly recent up-to-date version in their repos (version 20). Of course you'll get the latest patch release by using the official Docker repos, but they're on-par feature wise. So "these things are NOT bad" and WON'T "turn into a nightmare".

[@Coopertronics]

Yes please do an Alpine video. That system is super fast and robust. As far as I know the host system can't run a hardened kernel while running Docker, but Alpine is security based, so maybe that will negate the problem.

[@sokoloft3]

I re-did my vps earlier in the year using docker/docker images. Really nice having a pre-built package for nginx rtmp ingest with stunnel rtmps. I'll have to look into portainer. Only issues I have with it is maintaining it. Updating the container if a new image becomes available. As well as running commands inside the container.

[@blitzkringe]

Why running commands inside container is an issue? Isn't it as simple as just 'docker exec -it containername bash'?

[@joshua_lee732]

Want to update the container? Just use docker pull to grab the new image than re run the run command use the same container name, it'll recreate the container.

[@blitzkringe]

Docker is so awesome. I strongly believe that not only developers and cloud architects should be familiar with it, but any Linux user if he does any stuff fancier than just launching a web browser.

[@A_G420]

Been wanting to try docker & feel like this is a good video to get started with it. Thanks

[@Jool4832]

Have you checked out Podman?

[@avinashfernandes6612]

This. There is also podman-docker package for docker compatibility

[@ChrisTitusTech]

I need to dive into this, I have a fedora install on the inside rig and would be a perfect starting point.

[@iamrage4753]

@@ChrisTitusTech doing podman would be a great idea, managed with cockpit as no support for podman using portainer or yacht

[@themedleb]

Cockpit is amazing.

[@avinashlp713]

Same thought i had when i saw the title, Podman is so good man! Also, Great video Chris!

[@monad5]

what about the overhead of running every service in a docker container? what are your alternatives? especially when running multiple server services on a low performance machine

[@NachtmahrNebenan]

I use Docker as a kind of package manager when I install things without really installing it (deep into my system). For example databases, npm and the like. Local working files get mounted into the containers.

[@TheLazyJAK]

Please do a video on docker compose! It helped me learn about docker containers and their options etc way easier than those long one line commands. Much cleaner! Also check out rancher :)

[@sagichdirdochnicht4653]

Seriously! Docker-compose is around a billion times easier and more manageable. I mean it doesn't make a big difference for "one time deploys". But AS SOON as one is trying to modify the container, this is soooooo much better. Just modify the yml and up again with the container. LOL. Some people actually use portainer to manually deploy containers. It's like 5-10 Minutes of work for EVERY Container and EVERY time you just wanted to modify like a port or a volume. Docker-compose is just redicolously userfriednly compared to that.

[@C6438911]

If you have the time, you should also take a look or dive into 'distrobox'. its super handy utility to have (multiple) linux distro's inside your main distro your using.

[@CandyCaneChris]

Top things I end up helping people with when they start using docker are: Docker Desktop is only good for testing (use Portainer instead), volume mapping, and user permissions.

[@spookybuk]

One minute into a video saying this is for people like me (who don't know what Docker is) and still I don't know what Docker is :(

[@colinpotatofamine6183]

Docker is fun to mess with and makes running local network services really easy. Currently I have containers for: Transmission, Jupyterlab (this is super cool since I can do stuff anywhere on a super light, low powered laptop and the server is doing the heavy lifting), Homer, Nextcloud, Plex and Photoprism (probably getting rid of this since it seems redundant). Also dabbled with running Phantombot but never really had any use for that in the end.

[@mnhworkdev1652]

Love the fact you like the Inheritance Cycle

[@shubhamchavan757]

Productive Information Chris you should do a series on docker. Thanks buddy

[@thefearlessgeek]

I'm actually using Podman instead of Docker (it came with openSUSE MicroOS), but it's compatible with Docker images. I mostly use it for Distrobox and running Linux containers with that, but also setting up Wordpress development environments. And since I'm using an immutable distro, all my apps are flatpaks, appimages, or in docker containers anyway. So really, I use it for just about everything.

[@vagabondsajib9676]

Hey Titus, can you create a video about how to set up and use distro-box.

[@sherrilltechnology]

Thanks so much Chris such a great video and will help me on my channel as I am learning Docker right now!

[@cxl520]

I like docker compose over cli, it create nice layout. And easy adjust setting.

[@MysteryMan159]

Definitely marking this to watch later!

[@dimitristsoutsouras2712]

At 11.07 you omit to mention option -d which runs it s a daemon. I don t know how else it could have run but i see it with the -d parameter all the time. Another thing that makes me wonder is why the installation of docker is with the .io version, while the portainer with the .ce I f I can recall .ce has the latest images and not the .io

[@send2gl]

That was an interesting video. Got a bit confused with last yaml file creation but maybe if I watch again it will make more sense.

[@richardtwyning]

Wow, Portainer! So easy to set up! Thank you 🙂

[@kj2w]

I tend to use Docker only at home (work won't let us install Docker due to the daemon needed) and being a software engineer I will use it to run something like SQL Server to connect my apps to. Or another service like Redis for learning about cache.

[@diazepamkit]

its pretty nice to re cover the docker guide gg

[@Daggenthal]

Curious about your thoughts on Podman for RedHat, as you mentioned Kubernetes. Studying for my RHCSA at the moment and am learning Podman as well :)

[@bitterrotten]

Your cheat sheet is missing two things: - The keystroke to exit the container you exec'ed into. - docker system prune -a --volumes

[@JRVerster]

Excellent video, when are you going to do the Alpine video?

[@johnworoniuk477]

Very good tutorial. Thank you

[@dolvur]

Does anyone know what desktop environment or tiling manager he is using?

[@marek7673]

can you make tutorial about nexcloud or other NAS on docker?

[@carsondesignsstuff]

Chris wanted to ask your opinion on Windows N versions is this something worth using or regular versions of windows?

[@nicolasotero6424]

Nice video!! However, there are a lot of videos about standard docker. It could be a very interesting contribution a video about podman or rootless docker with the purpose of increasing the standard security. Another interesting idea would be how to work with Docker+firewalls.

[@BrotherPatrix]

I love Podman!

[@scudsturm1]

i have a question chris do i always need the latest kernel or is the one in mint 21 version 5.15 sufficient? i have a lenovo legion 5 with a Ryzen 5600H and an asrock deskmini a300 with a Ryzen 3200g i was wondering because wikipedia already shows kernel 6.0

[@badpickle2347]

How effective /efficient is docker inside proxmox? - - Also what is alpine Linux?

[@FHB71]

I am torn between Docker and K8s. Once you have managed all the housekeeping of K8s and are using Helm, K8s is IMHO much easier than Docker. But that hurdle has to be crossed first. You will get quicker results with Docker. In the end it doesn't matter. However for both the main disappointment is that neither is supported by Windows Server and I cannot understand why MS has stopped its path that was started a few years ago.

[@neon_Nomad]

Not docker related but recently found a ps script for a one click pihole wsl container created by the github user desktopEcho

[@13thravenpurple94]

Great video Thank you

[@billc3114]

What kind of development do you do Chris? Any Linux devel?

[@johnrussell6971]

I couldn't install the debian package (docker-desktop), it said that it couldn't install docker-ce-cli, a dependency.

[@007kowalski]

which desktop environment are you using here?

[@Patricia-kk8tr]

I have a 8gb mac mini 2014 1tb nvme, and want to stream and have pi-hole on the mac. Portainter hasn't been developed since Mojave so docker-compose was suggested in the comments. Does that support a low power system like mine? Does docker-compose have same access to images for alpine, Ubuntu server edition with script for LMS music streaming, and abcde ripper?

[@marang33]

Hey Chris, awesome video. Can you make a Windows version? I don't have Ubuntu.

[@blitzkringe]

Docker for Windows is a joke.

[@Lordofrimgs]

OMG omg here comes the life saving video..

[@robxlove]

What about the Dockerfile?

[@RandomPickles]

nvidia docker container toolkit on LMDE6 is a nightmare. Wont let me get it running no matter what.

[@whoismab]

Can you make review video on FYDEOS…

[@jeremiassamuelzitnik]

But why would u use docker instead od VM?

[@blitzkringe]

Because of performance overhead. Running an app in a container is as fast as running it on a bare host system.

[@jeremiassamuelzitnik]

@@blitzkringe nice

[@danielc.6644]

But is this explosed to the outside? I only want to use it in localhost

[@LordHonkInc]

TL;DR: You can use dockers for localhost-only things, yes. I give this information from experience but without warranty: docker containers are limited to your local machine unless and until you give them access to the local machine's network (for example by port-forwarding into/out of the container). I use local docker instances and am reasonably sure they're not communicating to the outside world (which I tested by unplugging my router from the internet and seeing that my containers didn't notice the difference).

[@betterstack]

Great stuff Chris! 🚀If anyone’s looking for more Docker videos, we’ve released a web-based Docker viewer and a logging tutorial to help the community too 💪

[@carlosdantenicolasdelafuen1293]

👏👏👏 Gracias 👍

[@prakhars962]

For people working on HPC clusters/supercomputers Docker is useless. We use Apptainer.

[@MoAbualruz]

Not totally true, it is much easier to use Apptainer or Kubernates or whatever more scalability minded engines, but if you have proper scripts and pipelines and checks, preferably with some automation with ansible or any automation tool of your choice you can get all what you want from plain docker. So I would not call it useless I would call it less optimal
