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?
Podman
- rootless by default
- daemonless
- integration with systemd, made even easier by
podman-generate-systemd
- no third-party APT repository required, follows the same lifecycle as my LTS (Debian) distro
podman
anddocker
command-line are 100% compatible for my use cases
podman-generate-systemd
is outdated. The currently supported way to run podman containers using systemd services would be Quadlet files.https://docs.podman.io/en/latest/markdown/podman-systemd.unit.5.html
Edit: I just saw that you use debian so idk if Quadlets are a thing with the podman version on debian.
