Welcome to the Podman playground. Its purpose is to allow readers to learn Podman by doing Podman.
What is Podman?
According to podman.io:
"Podman is a daemonless, open source, Linux native tool designed to make it easy to find, run, build, share and deploy applications using Open Containers Initiative (OCI) Containers and Container Images. Podman provides a command line interface (CLI) familiar to anyone who has used the Docker Container Engine. Most users can simply alias Docker to Podman (alias docker=podman) without any problems. Similar to other common Container Engines (Docker, CRI-O, containerd), Podman relies on an OCI compliant Container Runtime (runc, crun, runv, etc) to interface with the operating system and create the running containers. This makes the running containers created by Podman nearly indistinguishable from those created by any other common container engine."
In short, Podman is a container management technology that provides a good many features that go well beyond simply creating and destroying containers. In fact, you can use Podman to create a pod. A pod is a technique for organizing containers in a way that is similar to the way that Kubernetes organizes containers.
Executing command line instructions
This scenario is completely interactive. The instructions you'll be given will be executed directly in the terminal window that is embedded in the Katacoda interactive learning environment. When you see a command line instruction against a black background and check mark at the end, like so:
just click on it and the command will execute in the interactive terminal window.
Click the START SCENARIO button to start.
