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 tried a couple of times to get Docker running rootlessly on my local machine, without just granting root-like permissions to the user. Spent a few hours reading just the worst documentation that tells you to do things with absolutely no explanation of why, feeling like an idiot.

    Then I installed Podman. It worked more-or-less out of the box, and I got on with the rest of my project.
