- Added custom logging macros (log_error!, log_warn!, log_info!, log_debug!)
- Implemented LogLevel enum and LOG_LEVEL static for runtime level control
- Exported macros with #[macro_export] for use across all modules
- Replaced all log:: calls in websocket_client.rs, health.rs, and version.rs
- Removed obsolete test code referencing old log crate
- Removed log dependency from Cargo.toml
- Fixed useless comparison warning in test
- Binary size: still 1.5M (no change - log was lightweight)
- Tests: 65 passing, 0 warnings
This completes the removal of 9 dependencies (thiserror, hostname, chrono,
base64, rand, ureq, tiny_http, anyhow, log). Dependency count: 19 → 10.

Features:
- Parse and compare semantic versions from Docker Hub
- Check if current version is outdated on startup
- Only pull updates when newer version is available
- GitLab CI now tags images with Cargo.toml version
- Created bump-version.sh script for easy version bumping
How it works:
1. Cargo.toml contains source of truth version (0.1.0)
2. GitLab CI extracts version and tags Docker images with it
3. Agent queries Docker Hub for all semver tags
4. Compares current version against latest available
5. Only pulls and restarts if newer version exists
Version bumping workflow:
./scripts/bump-version.sh patch # 0.1.0 -> 0.1.1
./scripts/bump-version.sh minor # 0.1.0 -> 0.2.0
./scripts/bump-version.sh major # 0.1.0 -> 1.0.0
This creates git commit and tag, ready to push.
The previous version checking didn't work because:
- GitLab CI only creates semver tags when pushing Git tags
- Most builds use SHA hash tags, not version tags
- Comparing versions was unreliable
New approach:
- Simply pulls latest tag every hour
- Checks docker pull output to see if image changed
- Only restarts if a new image was actually pulled
- Logs the last_updated timestamp from Docker Hub for visibility
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
