How do I stop Authentik from resetting the permissions in the Docker directory mounts?

[SpencerDub]

I am running Authentik in a Docker container, and on my host machine, Docker runs using the dedicated appuser user.

Every time I restart Authentik, the /media and /templates directories have their permissions returned to a different user and group (my personal user account on the host system), so I have to go in and re-chown them. I also note that the target for the redis /data directory is owned by openmediavault-webgui:root, which is not the appuser:appmgr I want, and the postgresql container's /var/lib/postgresql/data is owned by 70:root on the host system. Also not my preferred user.

This is inconvenient, of course, and I'd really appreciate not having to take this step. Notably, I can't upload images (such as background images for flows) without first fixing these permissions.

I'll attach my Docker Compose file below. What modifications do I need to make so that Authentik can still function, but I don't have to re-chown these directories back to appuser:appmgr every time?
