You haven't provided any details as to the version of Red Hat or the error message.  However you are following a howto for Arch linux with a huge amount of added complexity.  Please ditch the howto!  The installation instructions for most distros (dnf/yum install...) are right here:  

https://podman.io/getting-started/installation

Once installed, you should be able to (as user not root):

podmand build -t myimage Dockerfile

podman run -it --name myimage bash
