Auto-deploy and auto-heal agent for self-hosted Docker containers
Push to your local registry. Dockward deploys via compose, health-checks the result, and rolls back automatically.
Features
Auto-update
Polls a local Docker registry; redeploys a compose service the moment a new image digest lands.
Rollback
Tags the previous image before every deploy; reverts automatically if the new container fails to become healthy.
Auto-heal
Listens to Docker health events; restarts unhealthy containers with per-service cooldown to prevent restart storms.
Multi-image services
One service entry can track multiple images; a single compose redeploy fires when any image changes.
Heal-only mode
Watch and recover a service without ever touching its image — useful for third-party or pinned containers.
Blocked digest protection
Blocks a known-bad digest in memory; skips it until a new digest is pushed, the service is manually unblocked, or dockward restarts.
Resource alerts
Per-container CPU and memory thresholds with independent cooldowns; fires notifications before a service falls over.
Audit log
Append-only JSONL file of every deploy, rollback, restart, and alert — full trail for post-mortems.
Live web UI
Real-time dashboard over SSE; shows service health, deployed image, container list, and recent events without page reloads.
Prometheus metrics
Counters and gauges for updates, rollbacks, restarts, and failures; drop into any existing Grafana setup.
Notifications
Discord webhook, SMTP email, and arbitrary HTTP webhooks; each event type is independently configurable.
HTTP API
/status, /trigger, /unblock, /audit, /metrics — automate or integrate with any toolchain.
Warden mode
Central aggregator for multi-machine fleets; agents push audit entries over HTTP, warden exposes a unified SSE dashboard.
Single binary
Zero runtime dependencies, ~12 MB; ships as linux/amd64, linux/arm64, and darwin/arm64.
Compose-native
Delegates all deploys to docker compose up -d — no custom orchestration.
Systemd-ready
Ships with service units for both agent and warden modes; systemctl enable dockward and done.
