Getting Started with Podman Manage Images, Containers and Volumes

Podman is a container runtime that provides features similar to Docker. It's part of the libpod library and can be used to manage pods, containers, container images, and container volumes. Podman was very different from Docker which uses the client-server architecture and required a docker daemon in order to run, while Podman doesn't require any daemon to run and also can be run flawlessly without root privileges.

In this tutorial, we will show you the basic usage of Podman for managing containers, images, and volumes, and creating container images. In order to complete this guide, you must have podman installed
