I am trying to install PostgreSQL_Alpine (I'm following the Ibracorp video on Authentik install). I get the following error message when it tries to install.

Diagnostic is also attached

Please look for the support thread for that container:

There doesn't seem to be forum thread for this application. I posted on the Github. Was hoping someone in the Unraid Forum might have an idea.

On further inspection of the github, it might be a bug.

If this is Postgres 18, they changed the mount point. The container path should be "/var/lib/postgresql".

How would I do this in unraid?

I just encountered this and it's an issue with the official template. To resolve the issue with the error (for those who may be searching like me):

docker: Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error mounting "/mnt/cache/appdata/postgresql_alpine" to rootfs at "/var/lib/postgresql/data": change mount propagation through procfd: open o_path procfd: open /var/lib/docker/btrfs/subvolumes/<uniquekey>/var/lib/postgresql/data: no such file or directory: unknown.

You just need to edit the Docker configuration as follows:

1) Edit the "Database Storage Path" path.

2) Change the "Container Path" from /var/lib/postgresql/data to /var/lib/postgresql

3) Apply

That error should go away as the path is now mapped correctly in the container.
