# BetterDesk — Single Container Image
|
|
# =====================================
|
|
# Combines Go server (signal + relay + API) and Node.js web console
|
|
# into a single container using supervisord as process manager.
|
|
#
|
|
# Build: docker build -t betterdesk:local .
|
|
# Run: docker compose up -d
|
|
#
|
|
# Ports:
|
|
# 21121 - HTTP API (Go server: RustDesk client API + REST)
|
|
# 21115 - NAT type test
|
|
# 21116 - Signal TCP/UDP
|
|
# 21117 - Relay TCP
|
|
# 21118 - WebSocket Signal
|
|
# 21119 - WebSocket Relay
|
|
# 5000 - Web Console (Node.js admin panel)
|
