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.

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!

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.

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".

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.

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.

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 Жыл бұрын

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.

@sokoloft3 Жыл бұрын

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 Жыл бұрын

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

@joshua_lee732 8 ай бұрын

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.

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.

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.

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.

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?

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

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.

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

@MoAbualruz Жыл бұрын

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

@LordHonkInc 9 ай бұрын

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).
