Implements complete companion agent for Rust servers not on managed panels.
Features:
- NATS integration with token auth and auto-reconnect
- Game server process management (start/stop/restart/monitor)
- File operations (read/write/delete/list) via NATS
- SteamCMD integration for automated updates
- Self-update capability with download and replace
- Heartbeat publishing every 60s with server status
- Graceful shutdown handling (SIGTERM/SIGINT)
- Zombie process prevention via cmd.Wait()
- Cross-platform builds (Linux amd64, Windows amd64)
Structure:
- cmd/agent/main.go: Entry point, config, signal handling
- internal/app/daemon.go: Main loop, NATS subscriptions
- internal/client/nats.go: NATS connection with reconnect
- internal/process/gameserver.go: Process management
- internal/process/steamcmd.go: Steam update execution
- internal/files/operations.go: File system operations
- internal/update/updater.go: Self-update logic
- Makefile: Cross-compilation targets
- README.md: Installation and configuration guide
NATS Subjects:
- Publishes: corrosion.{license_id}.companion.heartbeat
- Publishes: corrosion.{license_id}.files.response
- Subscribes: corrosion.{license_id}.cmd.server
- Subscribes: corrosion.{license_id}.files.{get|put|delete|list}
- Subscribes: corrosion.{license_id}.update.steam
- Subscribes: corrosion.{license_id}.update.companion
