+# Dockerfile Language Prompt Snippet
+
+## Key Concepts
+
+- **Multi-Stage Builds**: Multiple `FROM` statements to separate build and runtime stages, reducing image size
+- **Layer Caching**: Each instruction creates a layer; order instructions from least to most frequently changing for cache efficiency
+- **Base Images**: `FROM image:tag` selects the starting image; prefer slim/alpine variants for smaller images
+- **COPY vs ADD**: `COPY` for local files (preferred), `ADD` for URLs and tar extraction
+- **Build Arguments**: `ARG` for build-time variables, `ENV` for runtime environment variables
+- **Health Checks**: `HEALTHCHECK` instruction for container orchestrator readiness probes
+- **Entry Point vs CMD**: `ENTRYPOINT` sets the executable, `CMD` provides default arguments
+- **User Permissions**: `USER` instruction to run as non-root for security
+- **Ignore Patterns**: `.dockerignore` excludes files from the build context (like `.gitignore`)
+
+## Notable File Patterns
+
+- `Dockerfile` — Primary container image definition (at project root)
+- `Dockerfile.dev` / `Dockerfile.prod` — Environment-specific Dockerfiles
+- `docker-compose.yml` — Multi-container application orchestration
+- `docker-compose.override.yml` — Local development overrides
+- `.dockerignore` — Build context exclusion patterns
+
+## Edge Patterns
+
+- Dockerfile `deploys` the application entry point it packages (COPY/CMD target)
+- docker-compose `depends_on` Dockerfile(s) it references for building
+- Dockerfile `depends_on` package manifests (package.json, requirements.txt) it copies for dependency installation
+- docker-compose services create `related` edges between co-deployed components

+## Summary Style
+
+> "Multi-stage Docker build producing a minimal Node.js production image with N build stages."
+> "Docker Compose configuration orchestrating N services with shared networking and persistent volumes."
+> "Development Dockerfile with hot-reload support and mounted source volumes."
