Podman

Podman, short for Pod Manager, is a daemonless container engine and a drop-in replacement for Docker. It can be used in both root and non-root mode.

Starting with Red Hat Enterprise 8, Podman replaces Docker.

Pros include:

• No privileged daemon which is both a security risk and a single point of failure
• Works like docker with similar commands
• Docker images are compatible (based on OCI spec)
• Root-less containers
• Built with Kubernetes in mind (generates kube specs)

Cons:

• No docker-compose equivalent.

Changes:

• /var/lib/containers instead of /var/lib/docker
• Images also located at ~/.local/share/containers
