+# Docker setup for PolicyEngine Household API
+
+This repository publishes a hardened Docker image to GitHub Container Registry.
+
+## Features
+
+### Security hardening
+- Multi-stage build to minimize image size
+- Non-root user execution (uid 1000)
+- Read-only root filesystem compatible
+- No unnecessary capabilities
+- Health checks included
+- Regular vulnerability scanning with Trivy and Grype
+
+### CI/CD pipeline
+The GitHub Actions workflow:
+- Builds on push to main and tags
+- Multi-platform support (linux/amd64, linux/arm64)
+- Automatic versioning from git tags
+- SBOM (Software Bill of Materials) generation
+- Vulnerability scanning and reporting
+- Results uploaded to GitHub Security tab
+
+## Using the image
+
+Pull the latest image:
+```bash
+docker pull ghcr.io/policyengine/policyengine-household-api:latest
+```
+
+Run the container:
+```bash
+docker run -p 8080:8080 \
+  -e AUTH0_ADDRESS_NO_DOMAIN=your_auth0_address \
+  -e AUTH0_AUDIENCE_NO_DOMAIN=your_auth0_audience \
+  ghcr.io/policyengine/policyengine-household-api:latest
+```
+
+## Building locally
+
+```bash
+docker build -t policyengine-household-api .
+```
+
+## Environment variables
+
+Required environment variables:
+- `AUTH0_ADDRESS_NO_DOMAIN`: Auth0 domain address
+- `AUTH0_AUDIENCE_NO_DOMAIN`: Auth0 API audience
+- `PORT`: Server port (defaults to 8080)
+
+Optional for database connectivity:
+- `USER_ANALYTICS_DB_USERNAME`
+- `USER_ANALYTICS_DB_PASSWORD`
+- `USER_ANALYTICS_DB_CONNECTION_NAME`
+- `ANTHROPIC_API_KEY`
+
+## Workflows
+
+- **docker-publish.yml**: Builds and publishes images on push to main
+- **security-scan.yml**: Weekly vulnerability scans of the latest image
