Podman
A daemonless, Docker-compatible container engine from Red Hat that runs containers rootless by default.
What Is Podman in Linux?
Podman runs containers as direct child processes with no central root daemon, and it accepts nearly the same commands as Docker (alias docker=podman works for most workflows).
It supports pods (groups of containers sharing a network, as in Kubernetes) and integrates with systemd through Quadlet files, making containers first-class system services.
Example
podman run -d -p 8080:80 docker.io/library/nginxLearn more about Podman
- Docker and Podman: Container Basics on Linux An introduction to running containers on Linux with Docker and Podman: images, containers, the core commands you need day to day, and how the two tools differ.
- Podman Quadlet: Containers as Real systemd Services Quadlet turns a short declarative file into a generated systemd unit, so containers get dependency ordering, journal logging, and restart handling from systemd instead of from a container runtime.
- Rootless Containers: Running Podman and Docker Without a Root Daemon Rootless containers run as your ordinary user, so a container escape lands in an unprivileged account rather than as root. Here is how the UID mapping works and which limitations you will actually hit.
