A lot of people are interested in rootless Podman. This tool lets you build, install, and play with containers without requiring users to run as root, or have a big root-running daemon on their systems. Instead, Podman (by default) stores container images in the user’s home directory. Podman takes advantage of user namespaces in order to do this since most container images have more than one UID in the image.
Using rootless Podman with NFS requires a bit of extra work, but it can be done!
