+# Docker Build Optimization Guide
+
+This document describes the optimizations implemented in our Docker CI/CD pipeline for faster builds and better caching.
+
+## Overview
+
+Our optimized Docker build pipeline includes:
+- Self-hosted runner support with automatic fallback
+- Multi-stage builds for efficient layering
+- Advanced caching strategies
+- Container-based testing
+- Parallel builds for multiple images
+- Security scanning integration
+
+## Self-Hosted Runners
+
+### Configuration
+- **Labels**: `self-hosted, linux, x64, docker`
+- **Usage**: All Docker builds use self-hosted runners for improved performance and caching
+- **Local Cache**: Self-hosted runners maintain Docker layer cache between builds
+- **Fallback**: Manual fallback to GitHub-hosted runners if self-hosted are unavailable
+
+### Runner Setup
+Self-hosted runners provide:
+- Persistent Docker layer cache
+- Faster builds (no image pull overhead)
+- Better network throughput for pushing images
+- Cost savings on GitHub Actions minutes
+
+### Fallback Strategy
+If self-hosted runners are unavailable:
+1. Workflow will queue waiting for runners
+2. Can be manually cancelled and re-run with modified workflow
+3. Consider implementing automatic fallback in future iterations
+
+## Multi-Stage Dockerfile
+
+Our Dockerfile uses multiple stages for optimal caching and smaller images:
+
+1. **Builder Stage**: Compiles TypeScript
+2. **Prod-deps Stage**: Installs production dependencies only
+3. **Test Stage**: Includes dev dependencies and test files
+4. **Production Stage**: Minimal runtime image
+
+### Benefits
+- Parallel builds of independent stages
+- Smaller final image (no build tools or dev dependencies)
+- Test stage can run in CI without affecting production image
+- Better layer caching between builds
+
+## Caching Strategies
+
+### 1. GitHub Actions Cache (GHA)
+```yaml
+cache-from: type=gha,scope=${{ matrix.image }}-prod
+cache-to: type=gha,mode=max,scope=${{ matrix.image }}-prod
+```
+
+### 2. Registry Cache
+```yaml
+cache-from: type=registry,ref=${{ org }}/claude-hub:nightly
+```
+
+### 3. Inline Cache
+```yaml
+build-args: BUILDKIT_INLINE_CACHE=1
+outputs: type=inline
+```
+
+### 4. Layer Ordering
+- Package files copied first (changes less frequently)
+- Source code copied after dependencies
+- Build artifacts cached between stages
+
+## Container-Based Testing
+
+Tests run inside Docker containers for:
+- Consistent environment
+- Parallel test execution
+- Isolation from host system
+- Same environment as production
+
+### Test Execution
+```bash
+# Unit tests in container
+docker run --rm claude-hub:test npm test
+
+# Integration tests with docker-compose
+docker-compose -f docker-compose.test.yml run integration-test
+
+# E2E tests against running services
+docker-compose -f docker-compose.test.yml run e2e-test
+```
+
+## Build Performance Optimizations
+
+### 1. BuildKit Features
+- `DOCKER_BUILDKIT=1` for improved performance
+- `--mount=type=cache` for package manager caches
+- Parallel stage execution
+
+### 2. Docker Buildx
+- Multi-platform builds (amd64, arm64)
+- Advanced caching backends
+- Build-only stages that don't ship to production
+
+### 3. Context Optimization
+- `.dockerignore` excludes unnecessary files
+- Minimal context sent to Docker daemon
+- Faster uploads and builds
+
+### 4. Dependency Caching
+- Separate stage for production dependencies
+- npm ci with --omit=dev for smaller images
+- Cache mount for npm packages
+
+## Workflow Features
+
+### PR Builds
+- Build and test without publishing
+- Single platform (amd64) for speed
+- Container-based test execution
+- Security scanning with Trivy
+
+### Main Branch Builds
+- Multi-platform builds (amd64, arm64)
+- Push to registry with :nightly tag
+- Update cache images
+- Full test suite execution
+
+### Version Tag Builds
+- Semantic versioning tags
+- :latest tag update
+- Multi-platform support
+- Production-ready images
+
+## Security Scanning
+
+### Integrated Scanners
+1. **Trivy**: Vulnerability scanning for Docker images
+2. **Hadolint**: Dockerfile linting
+3. **npm audit**: Dependency vulnerability checks
+4. **SARIF uploads**: Results visible in GitHub Security tab
+
+## Monitoring and Metrics
+
+### Build Performance
+- Build time per stage
+- Cache hit rates
+- Image size tracking
+- Test execution time
+
+### Health Checks
+```yaml
+healthcheck:
+  test: ["CMD", "curl", "-f", "http://localhost:3002/health"]
+  interval: 30s
+  timeout: 10s
+  retries: 3
+```
+
+## Local Development
+
+### Building locally
+```bash
+# Build with BuildKit
+DOCKER_BUILDKIT=1 docker build -t claude-hub:local .
+
+# Build specific stage
+docker build --target test -t claude-hub:test .
+
+# Run tests locally
+docker-compose -f docker-compose.test.yml run test
+```
+
+### Cache Management
+```bash
+# Clear builder cache
+docker builder prune
+
+# Use local cache
+docker build --cache-from claude-hub:local .
+```
+
+## Best Practices
+
+1. **Order Dockerfile commands** from least to most frequently changing
+2. **Use specific versions** for base images and dependencies
+3. **Minimize layers** by combining RUN commands
+4. **Clean up** package manager caches in the same layer
+5. **Use multi-stage builds** to reduce final image size
+6. **Leverage BuildKit** features for better performance
+7. **Test in containers** for consistency across environments
+8. **Monitor build times** and optimize bottlenecks
+
+## Troubleshooting
+
+### Slow Builds
+- Check cache hit rates in build logs
+- Verify .dockerignore is excluding large files
+- Use `--progress=plain` to see detailed timings
+- Consider parallelizing independent stages
+
+### Cache Misses
+- Ensure consistent base image versions
+- Check for unnecessary file changes triggering rebuilds
+- Use cache mounts for package managers
+- Verify registry cache is accessible
+
+### Test Failures in Container
+- Check environment variable differences
+- Verify volume mounts are correct
+- Ensure test dependencies are in test stage
+- Check for hardcoded paths or ports
