Jellyfin can expose metrics in Prometheus format, but this functionality
is disabled by default. To enable it, we must set `EnableMetrics` in
the configuration file. This commit adds a template configuration file
that uses the `jellyfin_enable_metrics` Ansible variable to control this
value.
Expose a virtual host on a separate TCP port that uses the PROXY
protocol. This way, HAProxy can pass the original client IP address to
Jellyfin without terminating the TLS connection.
In order to enable authentication using LDAP over TLS in Jellyfin, we
need to expose the CA certificate that issues the LDAP server
certificates to the container.
Jellyfin is a multimedia library manager. Clients can browse and stream
music, movies, and TV shows from the server and play them locally
(including in the browser).
