Hosting the seafile docker image on non-root URL

On the manual there’s a page addressing the option of hosting seafile on a non root URL, but it does not mention doing this with the official docker image. Is this possible with the current seafile image? How can I enable this feature?

It seems like I’m making my own image then, operating system containers suck because of this very reason.

Sorry that I have to say that, but I wouldn’t use the official Docker images anyway. If you want to use Docker I think you currently run way better with your own image.

It might be worth searching GitHub and GitLab for existing images.
