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 think one of the issues I had was trying to run pihole with podman on a raspberry pi. I could not get DNS requests to work by just mapping the right ports. I ended up just running with --net=host and it worked, I didn’t feel like debugging further.

    I had other issues on my NAS but I don’t remember what it was, I have a lot of services on it, qBittorrent, Wireguard, Jellyfin, Jackett, netdata, prometheus, samba, syncthing, pihole (redundant), wsdd all in docker.
