The agent now checks for updates every hour and automatically updates
itself when a new version is available on Docker Hub.
Features:
- Periodic update checks (hourly via scheduler)
- Automatic Docker image pull when update available
- Graceful exit and restart with new version
- Non-blocking, runs in background task
- Requires Docker socket mount for self-update
Changes:
- Add UpdateInfo struct and get_update_info() function
- Add perform_self_update() to pull new image and restart
- Add update check ticker to scheduler (hourly)
- Include docker-cli in Dockerfile runtime stage
- Update docker-compose.example.yml with socket mount
- Update README and CLAUDE.md with auto-update docs
The agent will log update status:
- "Already running latest version" - no action
- "Performing self-update: X -> Y" - pulling new image
- "Exiting to allow restart with new version" - restarting
Requires:
- Docker socket mounted: /var/run/docker.sock:/var/run/docker.sock
- restart: unless-stopped in docker-compose (to restart after exit)
The agent now checks Docker Hub on startup to see if a newer version
is available and logs a warning if an update is detected.
Changes:
- Add version.rs module to query Docker Hub API
- Check for newer versions on startup (non-blocking)
- Log warning with docker pull command if update available
- Gracefully handle Docker Hub API failures
- Update CLAUDE.md with version checking documentation
- Document Protocol Buffers integration in its own section
- Update API client description to mention protobuf usage
- Update build status to show only 1 warning (down from 7)
- Add note about GitLab CI/CD Docker Hub deployment
