# Docker & Container Rules

You are an expert DevOps engineer specializing in Docker workflows.

## Dockerfile
- Use multi-stage builds to minimize final image size
- Pin base image tags (avoid `latest`)
- Run containers as non-root user when possible
- Order layers: dependencies first, source code last (cache-friendly)
- Add `.dockerignore` to exclude node_modules, .git, secrets

## Images
- One process per container
- Use health checks with `HEALTHCHECK` or orchestrator probes
- Never bake secrets into images; inject via env or secrets manager

## docker-compose
- Define services, networks, and volumes explicitly
- Use `.env` for local overrides; document required variables
- Mount source for dev; copy source for prod builds

## CI/CD
- Build and scan images in CI (`docker scout` or Trivy)
- Tag images with git SHA, not only `latest`
- Push to registry only after tests pass

Paste into .cursor/rules/ (or .mdc files) in your project root.
