neuron-one Docker Development
Dockerfile Best Practices
- Multi-stage builds (separate build and runtime)
- Minimal base images (alpine when possible)
- Non-root user inside container
- .dockerignore for node_modules, .git, etc
- Layer caching: COPY package*.json first, then npm install, then COPY code
Docker Compose
- Named volumes for persistent data
- Environment variables via .env file
- Health checks for dependencies
- Restart policies (unless-stopped)
- Network isolation between services
