How to configure Grafana without grafana.ini in Synology NAS setup?

[TKASAKAWA]

Hi @alhazmy13,

I'm using your alhazmy13/telegraf-influxdb-grafana image on a Synology NAS (DSM 7.2-72806). Initially, I set it up using Docker, but now Grafana is running as a native installation (PID: 22932, port: 3003). The process indicates it's using /etc/grafana/grafana.ini (/usr/sbin/grafana-server --config=/etc/grafana/grafana.ini), but I cannot find this file when searching the system.

I'm facing a port conflict when setting up a reverse proxy (HTTPS:3003 → HTTP:3003) in DSM's "Login Portal" → "Reverse Proxy" because Grafana is already listening on port 3003. Additionally, Grafana does not appear in DSM's "Services" list.

My questions are:

1. If Grafana is compiled without using grafana.ini, how can I configure settings (e.g., change the port to 3004, enable HTTPS) using environment variables or command-line arguments?
2. What is the recommended way to resolve the port conflict and enable HTTPS on Synology NAS?
3. How can I ensure Grafana appears in DSM's "Services" list?

Any advice on safely configuring this setup would be greatly appreciated. Thank you!
