podman

Podman is a daemonless container engine for developing, managing, and running OCI Containers on your Linux System. Containers can either be run as root or in rootless mode.

Podman relies on an OCI compliant Container Runtime (runc, crun, runv, etc) to interface with the operating system and create the running containers.

There is a RESTFul API to manage containers. We also have a remote Podman client that can interact with the RESTFul service.

Podman Desktop is an open source graphical tool enabling you to seamlessly work with containers and Kubernetes from your local environment.
