I changed my server setup from docker to podman after upgrading to the new Debian 11. There podman is included in the stable release. But there is an better solution instead of using podman-compose (I had some really annoying bugs using it). There is an additional package in the unstable packe repository named "podman-docker". This package implements the docker socket and translates all commands to podman. So there's the possibility to use the normal docker-compose (apt install docker-compose / pip3 install docker-compose) and things like portainer where the docker socket is needed for.

Will you do a full podman for beginners from scratch course? Do you know if there is one on youtube which you would recommend ? There are many for docker but any video I found about podman were mostly either conference keynote, or someone just comparing podman with docker .

Thank you for the suggestion! But I probably won't do it, because I've done many videos on Docker. I'm also preparing a new Docker Beginner Guide for next week, that will come out. So that should cover anything to get started with containers, Podman is really just another implementation that's very similar to Docker. So I think the videos should cover it. .. hopefully.

I have a big issue with Podman - the inability to modify already created pod. If I want to add a new path to my Jellyfin server, why do I have to create the pod from scratch? Also those arrogant responses on Github when this feature is requested are enough to just don't care about Podman. Arrogant parts of the community are currently the biggest issue of a Linux community. So far the best implementation of container deployment (Docker in this case) for a home lab is in Unraid. There is nothing that comes close to that in terms of ease of use. Being able to manage everything about Docker in a GUI, which actualy works (looking at you TruNAS Scale) is amazing. Nothing stops you from using a terminal, but having choices is actually a good thing.

from another video I read this comment: keep in mind that containers created via docker-compose are not completely native to podman. because of this, it is not possible to create self-sufficient units for systemd and, accordingly, auto-update images will not work. so I would still use podman-compose

Thank you for the tutorial. I tried it out on Debian 11 and encountered many problems… it doesn't feel to be a good solution. First, podman compose wouldn't run with installed podman version so I had to upgrade podman to 3.4 which was not that easy because conflicts with dependencies. I was able to fix that after a while. And now, containers are starting without problems, but the app container can't communicate with the database container. I never had this problems using docker. This is very annoying and all is very unstable. Now I'm thinking about creating all containers manually… because this is working, I already tried it out.

Hey, thanks for your videos. Question about this one though. You pointed NPM to Cockpit via its assigned IP, and inside I had red flags go up. Won't the IP address potentially change especially after restarts and additional containers/services added? Is this a concern from a best-practice perspective? I know docker has internal dns for names of containers that are on the same docker network; is there a way to accomplish this similarly on podman? Thanks for any insight you may have to these questions, perhaps in the 2 yr since you posted this video, maybe you came across these concerns as well..

Hey Christian. hmm... Just wondering, Isn't it better not to give quick and easy access permissions to these ports, since they tend to be very important ports? As IT Specialists I think one of our roles is to try and block the unnecessary access to our server's ports, and be as rigorous as possible, Don't you think so? Is there a way to give Podman access permissions to these specific ports only? Great Collection of Tut. Videos 👌.. Keep it up...
