Podman is a lot like Docker: a tool for running OCI containers. While it maintains backwards compatibility with Dockerfile and docker-compose syntax, it offers a lot of other benefits:

  • daemonless: it can run containers without a daemon process running in the background.
  • Rootless: can run containers without root privileges
  • pods: can group containers into secluded pods, which share resources and network namespace

Podman has other features I haven’t explored yet, like compatibility with Kubernetes yaml file, and being able to run containers as systemd units.

Have you used podman before? What are your thoughts on it?

    Docker has rootless containers, too, although I think Podman has slightly better options for unprivileged uid management.

    I have not used Docker rootless, but I imagine podman has much better and more flexible network configuration as well?

    On systemd, I actually do not use systemd either, hence why I said I never tried those features. It is not a hard requirement at all. Though I have not tried to use any integrations with OpenRC and podman
