Podman actually works really well. Out-of-the-box virtually-no-configuration-needed rootless containers. It's also usable via docker-compose with a single env variable. (podman-compose wasn't up to par for us)

We've been using it for a couple of years running and managing hundreds of containers per server - no feeling of flakiness whatsoever. It's virtually zeroconf and even supports GPUs for those who need it. It's like docker but better, IMO.

Hope it gets a popularity boost from CNCF. Rooting for it.

Dumb question: is it rootless for users on something like macOS?

I'd love to get the benefits of Docker without the battery drain and the Docker software, but I'm not sure if Podman would help much with either.

On macOS it creates a centos VM to run containers in. Rootless simply means that the root user in a container maps to the runner outside and not as the actual system root.

Edit: .. because the runner is not needing to run as root
