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?

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?
You're viewing a single thread.
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.
