How is the transition from docker to podman? I'm using two compose scripts and like 10 containers each. And portainer to comfortably restart stuff on the fly
I can only provide my experience; it was a drop-in replacement. I have 7 services running and 3 db containers. I was able to migrate using the Podman official instructions without issue.
from what I can gather its currently recommended to use quadlets to generate systemd units to achieve what compose was doing. podman compose is a thing but IIRC I didn't find that was straight drop in and I had to change the syntax or formatting a bit for it to work and from the brief testing I have put in quadlets seems less hassle, but if you use a non systemd distro then I don't know.
I'd say about 99% is the same.
Two notable things that were different were:
The second one is also documented on the CUDA Container Toolkit site, and very easy to edit a compose file to use CDI instead.
There's also some small differences here and there like podman asking for a preferred remote source instead of defaulting to dockerhub.
