A free beginner’s course about installing and using Podman.
Podman’s integration with Kubernetes through the podman kube play command allows users to create pods, containers, and volumes from Kubernetes YAML files. This command reads the structured file and recreates the described resources, starting the containers within a pod and outputting the ID of the new pod or the name of the new volume.
Sometimes you must create your own Podman images. Building your own Podman images allows for greater customization, control, consistency, and organizational efficiency compared to using only public images. The investment upfront can pay dividends in the long run through improved security, consistency, and maintainability of your container infrastructure.

Podman-compose is a script that simplifies the use of Podman to manage multi-container setups. It interprets the docker-compose.yml file and creates a Podman-compatible setup. This means you can use your existing Docker Compose files with Podman, making the transition smoother if you’re moving from Docker to Podman.
Podman volumes allow you to persist data outside of the container’s file system. This is particularly important when you need to ensure that your application data is not lost when a container is stopped, restarted, or removed. In this lesson you will learn the basics of managing Podman volumes in the command line.

Podman, also known as the POD manager, is an open-source tool for developing, managing, and running containers on Linux systems. It was originally developed by Red Hat engineers along with the open-source community. Podman is designed to make it easy to find, run, build, share, and deploy applications using Open Containers Initiative (OCI) Containers and Container Images.
