Dockerized GeoServer micro-services
Podman’s aim is to be a secure open source replacement for Docker and not depending on one daemon with root rights in order to prevent being a single point failure.
A further design goal is being able to run containers with only user privileges.

Additionally Podman can create and play Kubernetes files for easing migration to k8s:

Integration with systemd including dependencies is also a feature of podman.
