Podman support isn't as direct as README may give hints to

[paxcalpt]

Readme says "Podman Support Claude Code Sandbox now supports Podman as an alternative to Docker. The tool automatically detects whether you're using Docker or Podman by checking for available socket paths"

However, after running:

$ podman machine init
$ podman machine start

then:

$claude-sandbox

I get:
