In my opinion the biggest advantage of podman is that it uses pods with basically the same config and behavior as kubernetes does. As long as you just use podman pods instead (or possibly via) compose files you likely just notice that only the pod has one (and not any more) veth interface, that you reach other containers inside a pod via localhost:$port (instead of $service-name:$port) but when you switch later on to kubernetes you are already familiar with some basics.
