fedora
April 30, 2026
Automatic update for buildah-1.43.1-1.fc42, skopeo-1.22.2-1.fc42, podman-5.8.2-1.fc42
Summary
podman (Pod Manager) is a fully featured container engine that is a simple
daemonless tool. podman provides a Docker-CLI comparable command line that
eases the transition from other container engines and allows the management of
pods, containers and images. Simply put: alias docker=podman.
Most podman commands can be run as a regular user, without requiring
additional privileges.
podman uses Buildah(1) internally to create container images.
Both tools share image (not container) storage, hence each can use or
manipulate images (but not containers) created by the other.
Update Information:
Automatic update for buildah-1.43.1-1.fc42, skopeo-1.22.2-1.fc42,
podman-5.8.2-1.fc42.
