Firstly, funkwhale has an official nginx container you can use as part of their main docker-compose cluster, however I've got a seperate container here so that it can be customised in the future... (I'm going to be adding Caddy to this amongst other things).

• Configure docker-compose.yml with updated paths to your Funkwhale media
• Configure nginx.conf to point to the IP of your Funkwhale API (it's not going to be 127.0.0.1)

docker-compose up -d
