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 typically don’t use podman to build images and you would instead use something like buildah.
Doesn’t podman use buildah under the hood?
