Automate Image Updates: Coolify Deployments via Docker Hub & GHCR

Effortlessly Keep Your Coolify Deployments Up-to-Date with Automated Image Checks

Streamline your DevOps processes with our expertly designed n8n workflow that automates the update and deployment of Docker images via Docker Hub and GitHub Container Registry (GHCR). This powerful automation ensures your Coolify services are always running the latest software versions by automatically triggering service restarts whenever new image digests are detected.

What This Workflow Does

• Operates on a customizable schedule that suits your DevOps cycle.
• Monitors specified Docker Hub image tags along with their Coolify service UUIDs to detect any newly released digests.
• Avoids processing previously examined digests, while preparing standard metadata for the newly identified ones.
• Checks defined GHCR image tags, retrieves authentication tokens, and extracts OCI digests from headers to determine new updates.
• Eliminates workflow redundancy by skipping already processed GHCR digests, ensuring focus on fresh updates.
• Seamlessly integrates updates from both Docker Hub and GHCR, making automated API calls to the Coolify “restart service” endpoint for optimal deployment efficiency.

Use Cases

• Continuous Deployment Automation: Ideal for SaaS operators who need to maintain a seamless, up-to-date deployment pipeline without manual intervention.
• Resource Efficiency for Automation Engineers: Enhances productivity by automating routine checks, thus freeing up resources for more critical tasks.
• Optimal for n8n Users: Perfect for those who leverage n8n for automation workflows and wish to integrate continuous deployment in their toolchain.

Technical Details

• Nodes leveraged: set, merge, split out, sticky note, HTTP request, schedule trigger.
• Integrations: Docker Hub, GitHub Container Registry (GHCR), Coolify API.
• Configuration requires: HTTP Bearer Auth credential setup, customizing image tag and service UUID arrays, and schedule interval adjustments.

Keep your Coolify deployments seamlessly up-to-date with this automated n8n workflow, designed for professionals who demand reliable and consistent service execution.
