This repository contains a GitHub Actions workflow that automatically builds and pushes multi-architecture n8n Docker images to GitHub Container Registry (GHCR).

The workflow (build.yml) performs the following steps:

1. Clone n8n Repository: Clones the official n8n repository from https://github.com/n8n-io/n8n
2. Setup Environment: Installs Node.js 22 and pnpm package manager
3. Install Dependencies: Runs pnpm install --frozen-lockfile
4. Build Project: Executes pnpm run build
5. Multi-Platform Docker Build: Builds Docker images for both AMD64 and ARM64 architectures using Docker Buildx
6. Create Multi-Arch Manifests: Combines platform-specific images into multi-architecture manifests
7. Push to GHCR: Tags and pushes the images to ghcr.io/mroplus/n8n:enterprise

The workflow runs on:

• Push to master branch
• Pull requests to master branch
• Manual trigger via GitHub Actions UI (workflow_dispatch)

The workflow creates multiple tags for the Docker image:

• ghcr.io/mroplus/n8n:enterprise - Main enterprise tag (multi-arch)
• ghcr.io/mroplus/n8n:latest - Latest build (multi-arch, only on master branch)
• ghcr.io/mroplus/n8n:<commit-sha> - Specific commit version from this repository (multi-arch)
• ghcr.io/mroplus/n8n:n8n-<n8n-commit-hash> - Specific n8n source repository commit version (multi-arch)

Platform-specific tags are also available:

• ghcr.io/mroplus/n8n:enterprise-amd64 - AMD64 specific image
• ghcr.io/mroplus/n8n:enterprise-arm64 - ARM64 specific image

The Docker images are built for multiple architectures:

• linux/amd64 - x86_64 processors (Intel/AMD)
• linux/arm64 - ARM64 processors (Apple Silicon, ARM servers)

The workflow uses Docker Buildx to create native builds for each platform, ensuring optimal performance on both architectures.

The workflow requires the following permissions (already configured):

• contents: read - To checkout the repository
• packages: write - To push Docker images to GHCR

The workflow uses the GITHUB_TOKEN automatically provided by GitHub Actions. No additional secrets need to be configured for GHCR access.

1. Push changes to the master branch or create a pull request
2. The workflow will automatically trigger and build the n8n Docker image
3. On successful completion, the image will be available at ghcr.io/mroplus/n8n:enterprise

To use the built Docker image:

# Pull the multi-architecture image (will automatically select the correct architecture)
docker pull ghcr.io/mroplus/n8n:enterprise
docker run -d --name n8n -p 5678:5678 ghcr.io/mroplus/n8n:enterprise

# Or pull a specific architecture if needed
docker pull ghcr.io/mroplus/n8n:enterprise-amd64  # For x86_64 systems
docker pull ghcr.io/mroplus/n8n:enterprise-arm64  # For ARM64 systems

• Check the Actions tab in your GitHub repository for build logs
• Ensure your repository has Actions enabled
• Verify that the GitHub Container Registry is accessible from your account
• Make sure the repository visibility allows package publishing

The workflow includes cleanup steps to prevent disk space issues and provides detailed logging for each build step.
