+Standalone templates such as `nginx`, `adminer`, `redis`, `portainer`, `mattermost`, `n8n`, `uptime-kuma`, and `vaultwarden` currently define only image and port unless their version config adds explicit environment variables. `rustdesk-server` uses the official all-in-one s6 image and requires `RELAY` to advertise the public relay endpoint; RustDesk clients also require firewall access to TCP `21115`, TCP/UDP `21116`, TCP `21117`, and optional web-client TCP `21118`/`21119`.
