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?
I switched from Dockerd to K3s. First you get the benefits of the Kubernetes API but also Pod Security Context, Pod Security Admission and Network Policies which help to reduce attack surface while simplifying your setup.
But if you do want to use Podman look into running your containers as read only, drop all capabilities and unprivileged.
