This article describes the installation and usage of Podman. Podman is a Docker replacement primarily driven by RedHat. It shares pretty much shares the syntax and behavior with docker. If you for example alias the docker command to podman (alias docker=podman), the end-user can use Podman in the same way they would use Docker. Podman comes without a daemon. This allows us to use Podman as a normal user with no root authorizations required. It’s fair to say that Podman is some kind of userland Docker with feature-rich developer extensions.
The installation of Podman is pretty much straight forward, simply install it through the package manager and we can use Podman straight away:
> dnf -y install podman
After logging out and log in again as “bofh”, you can now use Docker as a normal operator:
> podman run hello-world
