Podman or rootless docker?
Podman or rootless docker?
I’m moving to a new machine soon and want to re-evaluate some security practices while I’m doing it. My current server is debian with all apps containerized in docker with root. I’d like to harden some stuff, especially vaultwarden but I’m concerned about transitioning to podman while using complex docker setups like nextcloud-aio. Do you have experience hardening your containers by switching? Is it worth it? How long is a piece of string?

As long as you’re on Linux, podman is superior and will do all of the things you’re asking about. If you need to also support Windows or Mac, Docker is the only thing that will work (although people have told me Rancher isn’t bad now for a couple of years).

podman works on windows hosts, as long as you don't need windows containers
-
And as long as you don’t need simple access to most features such as volumes. The podman implementation on not Linux leaves quite a bit to be desired for anyone trying to do more than just run a binary wrapped in a container. I’m not throwing shade because it’s FOSS and anything is better than Docker. Only Docker will work for a production-capable dev environment on not Linux unless podman’s development has exponentially increased in the last year since I tried to move a shop to podman on not Linux.
