Docker installation

This docker compose file is inspired by the docker compose file created by Jims Garage at Gitea Synapse Jims Garage

Since, I use a centralised caddy reverse proxy plugin for OPNSense I commented out the Traefik labels and the proxy network.

    # Uncomment if not using a proxy. In order to expose Synapse, remove one of the following, 
    # you might for instance expose the TLS port directly:
    ports:
      - 8448:8448/tcp
      - 8008:8008/tcp

    # ... or use a reverse proxy, here is an example for traefik:
