Replaces Watchtower with per-container update policies, pre-update snapshots, automatic rollback, and real-time notifications.\n\n![Dashboard](https://raw.githubusercontent.com/wiki/Will-Luck/Docker-Sentinel/images/dashboard.png)\n\n## Features\n\n- **Per-container update policies** via Docker labels: `auto`, `manual`, or `pinned`\n- **Pre-update snapshots** with automatic rollback if a container fails health checks after updating\n- **Registry checks** with digest comparison for mutable tags and semver tag discovery with constraint pinning\n- **Web dashboard** with SSE live updates, stack grouping, container controls, and mobile-responsive layout\n- **Cluster mode** for monitoring and updating containers across multiple Docker hosts from a single dashboard\n- **11 notification providers** including Gotify, Slack, Discord, Ntfy, Telegram, Pushover, Email, MQTT, Apprise, and webhooks\n- **Authentication** with password, WebAuthn/passkeys, OIDC/SSO, and TOTP/2FA support\n- **Maintenance windows** with time-range expressions and per-container cron schedules\n- **Lifecycle hooks** with Docker-Guardian integration for coordinated maintenance labels\n- **Prometheus metrics** endpoint with an official Grafana dashboard template\n- **Update queue** for reviewing, approving, or rejecting pending updates with inline release notes\n- **Configuration export/import** for full settings backup and restore via the web UI\n\n## Quick Start\n\n```bash\ndocker run -d \\\n  --name docker-sentinel \\\n  --restart unless-stopped \\\n  -v /var/run/docker.sock:/var/run/docker.sock:ro \\\n  -v sentinel-data:/data \\\n  -p 8080:8080 \\\n  -e SENTINEL_POLL_INTERVAL=6h \\\n  willluck/docker-sentinel:latest\n\n# Or from GitHub Container Registry:\n# ghcr.io/will-luck/docker-sentinel:latest\n```\n\nOpen `http://localhost:8080` in your browser. On first visit you will be guided through the setup wizard to create an admin account.\n\n## Container Labels\n\nSet per-container update behaviour with Docker labels like `sentinel.policy`, `sentinel.semver-constraint`, `sentinel.cron`, and others. See the [Docker Labels](https://github.com/Will-Luck/Docker-Sentinel/wiki/Docker-Labels) wiki page for the full reference.\n\n\u003cdetails\u003e\n\u003csummary\u003e\u003cstrong\u003eUpdate Lifecycle\u003c/strong\u003e\u003c/summary\u003e\n\n1. **Scan** containers and check policies\n2. **Check** registries for new digests or semver tags\n3. **Queue** updates (auto-policy proceeds immediately, manual-policy waits for approval)\n4. **Snapshot** the full container config, then pull the new image before stopping anything\n5. **Update** the container: stop, remove, recreate with identical config, start\n6. **Validate** after the grace period, and rollback from the snapshot if the container is unhealthy\n\n\u003c/details\u003e\n\n## Screenshots\n\n| | |\n|---|---|\n| ![Dashboard](https://raw.githubusercontent.com/wiki/Will-Luck/Docker-Sentinel/images/dashboard.png) | ![Manage Mode](https://raw.githubusercontent.com/wiki/Will-Luck/Docker-Sentinel/images/dashboard-manage.png) |\n| ![Container Detail](https://raw.githubusercontent.com/wiki/Will-Luck/Docker-Sentinel/images/container-detail.png) | ![Queue](https://raw.githubusercontent.com/wiki/Will-Luck/Docker-Sentinel/images/queue.png) |\n| ![Cluster](https://raw.githubusercontent.com/wiki/Will-Luck/Docker-Sentinel/images/cluster.png) | ![Connectors](https://raw.githubusercontent.com/wiki/Will-Luck/Docker-Sentinel/images/connectors.png) |\n| ![Images](https://raw.githubusercontent.com/wiki/Will-Luck/Docker-Sentinel/images/images.png) | ![Settings](https://raw.githubusercontent.com/wiki/Will-Luck/Docker-Sentinel/images/settings-scanning.png) |\n\n## Documentation\n\nFull documentation is available in the **[Wiki](https://github.com/Will-Luck/Docker-Sentinel/wiki)**, covering:\n\n- [Installation Guide](https://github.com/Will-Luck/Docker-Sentinel/wiki/Installation)\n- [Configuration Reference](https://github.com/Will-Luck/Docker-Sentinel/wiki/Configuration-Reference)\n- [Docker Labels](https://github.com/Will-Luck/Docker-Sentinel/wiki/Docker-Labels)\n- [Web UI Guide](https://github.com/Will-Luck/Docker-Sentinel/wiki/Web-UI-Guide)\n- [REST API Reference](https://github.com/Will-Luck/Docker-Sentinel/wiki/REST-API-Reference)\n- [Authentication \u0026 Security](https://github.com/Will-Luck/Docker-Sentinel/wiki/Authentication-and-Security)\n- [Notifications](https://github.com/Will-Luck/Docker-Sentinel/wiki/Notifications)\n- [Cluster Mode](https://github.com/Will-Luck/Docker-Sentinel/wiki/Cluster-Mode)\n- [Lifecycle Hooks](https://github.com/Will-Luck/Docker-Sentinel/wiki/Lifecycle-Hooks)\n- [Troubleshooting](https://github.com/Will-Luck/Docker-Sentinel/wiki/Troubleshooting)\n\n## Building from Source\n\n```bash\nmake build      # Build binary to bin/sentinel\nmake frontend   # Build JS/CSS bundles (esbuild)\nmake docker     # Build Docker image\n```\n\nRequires Go 1.24+, Node.js, and Docker.\n\n## Licence\n\nApache Licence 2.0.
