Podman is an open source Open Container Initiative (OCI)-compliant container management tool created by Red Hat used for handling containers, images, volumes, and pods on the Linux operating system, with support for macOS and Microsoft Windows via a virtual machine. Based on the libpod library, it offers APIs for the lifecycle management of containers, pods, images, and volumes. The API is identical to the Docker API.
