Features:
- Health endpoint now returns git_commit SHA and version
- Auto-detects git commit during Docker build
- Falls back to 'unknown' if git info unavailable
- Allows AI agents to verify deployed version
Changes:
1. server.js: Add git_commit and version to /health response
2. Dockerfile: Add git installation and commit detection
3. Dockerfile: Accept GIT_COMMIT and APP_VERSION build args
4. docker-compose.yml: Pass build args and env vars for versioning
5. README.md: Document version tracking in health endpoint
Example response:
{
"status": "healthy",
"postgres": "connected",
"redis": "connected",
"timestamp": "2026-02-14T10:30:00.000Z",
"git_commit": "eb6b6e0a1b2c3d4e5f6g7h8i9j0k1l2m3n4o5p6q",
"version": "1.0.0"
}
