[Podman] Re: Python process unable to write files

All, I'm porting a legacy app to containers, and having an issue where apparently it can't write files while running in podman. Is there any reason why a python process, or child process, running as container-root would be unable to write to either the ephemeral filesystem of the container, or to mounted volumes? Basically, here's the situation: - pyhton app with many child processes - all of them run as container-root - app is supposed to write logs to files (yes, I know) - app does not write any logs to any files; in fact, the log-dir initialization appears to fail (no error messages, though, because it's not logging) - one other process which is supposed to write cache to a dir does not do so - all of these directories are under /app/ a directory COPYd into the image definition, not /var/ or home - have tried both with these dirs as local to the container, and as mounted volumes on the host system - if I exec in to the container as container-root, I can write files to those dirs - SELinux denial log on the host does not show any denials It is entirely possible that this is a problem with the legacy app and is not a podman thing at all.  I'm asking here because I want to eliminate podman as a potential cause of the problem.
