Auf meinem für einen ganzen Schwung von Aufgaben dienenden Raspberry Pi laufen Home Assistant, Whoogle, Watchtower und Portainer in Docker-Containern. Kurz- bis mittelfristig werden wohl noch weitere auf dieser Art bereitgestellte Dienste hinzukommen.
Möchte ich da eigentlich mittlerweile unbedingt zu podman wechseln? Oder sollte ich vorher genau recherchieren, in welchen Fällen podman aktuell doch noch nicht so ein passgenaues Drop-In-Replacement darstellt?

I know I’ve posted recently about containers, but I still regret not starting to use them earlier. It was because my hosting was ‘working’ and I did not see the need. But once I started getting more issues with upgrading some applications, I realised the benefits of containers.

Pre-made containers get distributed with just what’s necessary to run the application it contains. With a container engine, like Podman, Docker, or CRI-O, you can run a containerized application without installing it in any traditional sense. Container engines are often cross-platform, so even though containers run Linux, you can launch containers on Linux, macOS, or Windows.

One thing I had to get to grips with, was depending on the image you use to create your container, some just require pulling a new image to update the application, and some require the upgrade to be run as normal within the running application. You also want to be sure to do regular backups of any external volumes, as these contain user data that is not recreated by the container.

Run containers on Linux without sudo in Podman, it is also Docker compatible

Podman has two main advantages over Docker:
* Does not require root privileges to run Docker containers
* Has no single running daemon as a single point of failure

And although it is compatible with running and creating Docker containers, it cannot use Watchtower for automated checking of updates for containers. But with systemd managed containers there is an auto-update option for Podman which is worth looking at.
