+# Docker Setup for Frontier
+
+This directory contains Docker configuration files for running the Frontier template node.
+
+## Quick Start
+
+### Build
+```bash
+# Build and run the production node
+docker compose up --build
+```
+
+### Deploy development node
+```bash
+# Run a development node
+docker run -d   --name frontier-node   -p 9933:9933   -p 9944:9944   frontier-node   --dev   --rpc-cors=all   --rpc-external   --rpc-methods=Unsafe   --rpc-port 9933
+```
+
+## Files
+
+- `Dockerfile` - Production Docker image for the Frontier template node
+- `Dockerfile.dev` - Development Docker image with additional tools
+- `docker-compose.yml` - Production Docker Compose configuration
+- `docker-compose.dev.yml` - Development Docker Compose configuration with hot reloading
+- `.dockerignore` - Files to exclude from Docker build context
+
+## Ports
+
+- `30333` - P2P networking
+- `9933` - RPC endpoint
+- `9944` - WebSocket endpoint
+- `9615` - Prometheus metrics
+- `9090` - Prometheus (development only)
+
+## Volumes
+
+- `frontier_data` - Persistent chain data (production)
+- `frontier_dev_data` - Development build cache
+- `cargo_cache` - Rust cargo cache for faster builds
+
+## Development
+
+The development setup includes:
+- Hot reloading of source code
+- Debug logging enabled
+- Interactive bash shell
+- Cargo cache for faster builds
+- Optional Prometheus monitoring
