However, you might have realised that some commands which worked fine in Docker, simply don’t work in Podman doubly so, when SELinux is in charge. You’re tearing your hair out (if you have any). You get all sorts of errors about permissions, and…. you desperately want to avoid disabling SELinux, but you just end up reaching for setenforce 0 and running everything with sudo. In this article I’ll go through how to share a volume from your host machine with podman, when you’re running rootless containers. You need to understand how rootless podman works.I’ll also share a podman command you can use which really helps you in these situations. TLDR Advertisements Rootless podman vs rootful at a glance.Or, you could just run your process as the root user inside the container.Check that the permissions are OK, by listing the directory inside the container.Use podman unshare chown to grant the container user ID permissions to write to your directory.Get the UID of the container user first.How to allow a rootless podman container to write to a volume.podman unshare lets you run a command in the same user namespace as your containers.Rootless containers share the same user namespace.

This table shows you the 4 main rootless/rootful operating modes of Podman, and how they really work in practice. The first column is how you’re running podman.

Do you run the command as the root user (e.g. The second column is the user that the container process is running as.

You can set this with podman using the -u option - e.g. The third column shows who the process is really running as, on the host. The actual UID visible on the host is… root root 0 root non-root 0 non-root root Your UID non-root non-root A non-root UID You need to understand how rootless podman works That is, if you run ps -ef on the host, and find your containerised process, this is the UID that you will see in the process list.
