Wondering how to install and use Podman on Ubuntu 20.04 LTS?
Podman is a tool that’s designed for managing pods. It manages Containers of different types, mostly OCI. Podman can also be used to create and develop Containers on your Linux distribution.
Podman distinguishes itself from its competitors by allowing you to run Containers in both root and rootless mode. Additionally, Podman isn’t a running service, meaning that it’s daemonless.
With tempting features like this, Podman may be the solution to all your OCI-based Container problems. This guide is meant to help you learn how to install and use Podman on Ubuntu 20.04 LTS.
We will cover methods to install the service on your system and a basic tutorial on how to use Podman.
