Seafile Container + MariaDB Container + Nginx Proxy Manager (NPM) Container

Deploying Seafile via Docker on an Unraid system, pointing to another container running MariaDB. Running internally on HTTP. NPM container sits in front, with a HTTPS reverse proxy for the main site (http://seafile.domain.com).

NPM auto-generates its config I think? I am not sure if you can, let alone best-practice, to edit its config.

Anyone able to get the above combination to work?
