What is podman?

Podman is an open-source, Linux-based tool designed to build, run and deploy containers.

Podman is developed by the CoreOs team by keeping Docker in mind so that people familiar with Docker can quickly adopt podman.

Podman containers are OCI(Open Containers Initiative) based and similar to Docker.

Podman containers run as a rootless that provides additional security over docker containers.

All docker commands which developers are familiar with also in podman.

If you have existing scripts that run on a Docker, all you need to do is create a docker alias for podman, and all your scripts should work.

In general, docker pulls the images from dockerhub whereas podman pulls the images from the RedHat repo.

Podman is very well integrated with RedHat's openshift enterprise application offering.

Thank You
