Podman might have a “more secure” design but you can run the docker daemon as rootless. Podman itself is not immune to vulnerabilities and will not solve all your security problems.
Don’t let perfection be the enemy of good. Security is not all or nothing. Reducing the attack surface is still important.
Can you elaborate on running docker daemon as rootless? It’s my understanding that you can add your account to a group to access the docker daemon rootless, but the containers are still running as root, as the daemon itself raises the access to root.

No. The daemon can run without root, as such the containers don’t have root. My docker install doesn’t have root access. None of my stacks / containers need any root access tbh. I don’t have any troubles with deplyong stuff.
Not sure relying on podman alone as a security tool might be advisable. Podman is a container technology first, security is not the main goal.

I never said I was relying on it alone. Not sure why you think that.
That’s a great link. Thank you for sharing. It’s good that docker supports this functionality now.
