[Podman] rootless podman run container as user rather than root

Hi All Been looking at this one for a good few days, I think I might have the wrong idea of how it works so I'd like some advice. I created my container image - bioconda that all works nicely, and I can run it from my /home directory as follows: - podman run -v /home/bryan/data:/home/bryan:z -it bioconda This starts it up and I can create Directories and Files ok within it and they retain the correct uid and gid's, however some of my other images warn that you are running as root which I'd like to stop happening. Is it possible to use the userns=keep-uid to do this? I can't seem to make it work correctly if this is the way I'm interpreting it to do so. Thank you Bryan
