# 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)

# Note: supervisord requires root to manage child processes with user= directive.
# Both betterdesk-server and betterdesk-console run as non-root 'betterdesk' user
# via supervisord configuration (user=betterdesk).
