# 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."
