          I couldn't get the pod provided to actually work, so I built my own:

          In hind sight, the pod provided might actually work, given the following:
        

        

          
          

        

        

          
          Before attempting to run docker/podman command, ensure you mkdir .cache/ and
        

        

          
          chmod 777, otherwise pod won't be able to write in that directory and things
        

        

          
          break.
