Podman is a daemon-less alternative to Docker, but with Rootless containers, grouping containers in pods, and systemd integration. What do you think of it? (lemmy.ml)

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?

Ahh, I had skimmed over and didn't see you were running it on k8s (so kubernetes executor makes sense. ;) )

This is good to know though. I actually just stood up a podman runner and it is vastly improved over what I had to do even a year ago if I remember. I'll need to look into Testcontainers though too as we do use that. Good to know it's at least progressing pretty well. Thanks!
