# DockerfileExtra - Combined Windmill Extra Services
#
# This image extends windmill-slim with three optional Windmill services:
# - LSP (Language Server Protocol) - Port 3001
# - Multiplayer (y-websocket) - Port 3002
# - Debugger (DAP WebSocket) - Port 3003
#
# Each service can be enabled/disabled via environment variables:
# - ENABLE_LSP=true (default: true)
# - ENABLE_MULTIPLAYER=true (default: true)
# - ENABLE_DEBUGGER=true (default: true)
#
# Build:
#   docker build -f docker/DockerfileExtra -t windmill-extra .
#
# Run:
#   docker run -p 3001:3001 -p 3002:3002 -p 3003:3003 windmill-extra
