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?
Rootless Podman :) It requires you to learn a little bit of new syntax, for example, the way you mount volumes and pass environment variables can be slightly different, but there’s nothing that hasn’t worked for me.
I’m using this on uBlue uCore, which I would also strongly recommend for security reasons.
