🚀 Quick Start

docker run -d \
  --name drydock \
  -p 3000:3000 \
  -v /var/run/docker.sock:/var/run/docker.sock \
  codeswhat/drydock:latest

The image includes trivy and cosign binaries for local vulnerability scanning and image verification.

See the Quick Start guide for Docker Compose, socket security, reverse proxy, and alternative registries.

✨ Features

Container Monitoring Auto-detect running containers and check for image updates across registries	20 Notification Triggers Slack, Discord, Telegram, Teams, Matrix, SMTP, MQTT, HTTP webhooks, Gotify, NTFY, and more	23 Registry Providers Docker Hub, GHCR, ECR, GCR, GAR, GitLab, Quay, Harbor, Artifactory, Nexus, and more
Docker Compose Updates Auto-pull and recreate services via docker-compose with service-scoped compose image patching	Distributed Agents Monitor remote Docker hosts with SSE-based agent architecture	Audit Log Event-based audit trail with persistent storage, REST API, and Prometheus counter
OIDC Authentication Authelia, Auth0, Authentik — secure your dashboard with OpenID Connect	Prometheus Metrics Built-in /metrics endpoint with optional auth bypass for monitoring stacks	Image Backup & Rollback Automatic pre-update image backup with configurable retention and one-click rollback
Container Actions Start, stop, restart, and update containers from the UI or API with feature-flag control	Webhook API Token-authenticated HTTP endpoints for CI/CD integration to trigger watch cycles and updates	Container Grouping Smart stack detection via compose project or labels with collapsible groups and batch-update
Lifecycle Hooks Pre/post-update shell commands via container labels with configurable timeout and abort control	Auto Rollback Automatic rollback on health check failure with configurable monitoring window and interval	Graceful Self-Update DVD-style animated overlay during drydock's own container update with auto-reconnect
Icon CDN Auto-resolved container icons via selfhst/icons with homarr-labs fallback and bundled selfhst seeds for internetless startup	Mobile Responsive Fully responsive dashboard with optimized mobile breakpoints for all views	Multi-Registry Publishing Available on GHCR, Docker Hub, and Quay.io for flexible deployment

🔌 Supported Integrations

📦 Registries (23)

Docker Hub · GHCR · ECR · ACR · GCR · GAR · GitLab · Quay · LSCR · Harbor · Artifactory · Nexus · Gitea · Forgejo · Codeberg · MAU · TrueForge · Custom · DOCR · DHI · IBM Cloud · Oracle Cloud · Alibaba Cloud

🔔 Triggers (20)

Apprise · Command · Discord · Docker · Docker Compose · Google Chat · Gotify · HTTP · IFTTT · Kafka · Matrix · Mattermost · MQTT · MS Teams · NTFY · Pushover · Rocket.Chat · Slack · SMTP · Telegram

🔐 Authentication

Anonymous (default) · Basic (username + password hash) · OIDC (Authelia, Auth0, Authentik). All auth flows fail closed by default.

API note: POST /api/containers/:id/env/reveal is currently scoped to authentication only (no per-container RBAC yet), so any authenticated user is treated as a trusted operator for secret reveal actions.

🥊 Update Bouncer

Trivy-powered vulnerability scanning blocks unsafe updates before they deploy. Includes cosign signature verification and SBOM generation (CycloneDX & SPDX).

🔄 Migration

Migrating from WUD (What's Up Docker?)

Drop-in replacement — swap the image, restart, done. All WUD_* env vars and wud.* labels are auto-mapped at startup. State file migrates automatically. Use config migrate --dry-run to preview, then config migrate --file .env --file compose.yaml to rewrite config to drydock naming.

---

🗺️ Roadmap

Here's what's coming. WUD WUD_* env vars and wud.* labels remain fully supported at runtime — see 🔄 Migration for details.
