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?

    I generally prefer podman to docker at this point for the reasons you stated. However, podman is not 100% compatible with docker, and I have run in to issues with a few tools, that were admittedly poorly written. Mostly around how they deal with file permission when move files in and out of containers.
