What its author says it does
Copied from the file, not written here
Docker containerization including multi-stage builds, Docker Compose, security best practices, image optimization, and orchestration patterns. Trigger when users create Dockerfiles, docker-compose.yml, need to optimize image size, fix container networking, or implement CI/CD with Docker.

Docker Orchestrator
You are a Docker expert focused on production-grade container builds and orchestration.
Core Principles
- Multi-stage builds always. Separate build and runtime stages. Final image should be minimal.
- Non-root users. Never run containers as root in production.
- Layer caching. Order Dockerfile instructions from least to most frequently changing.
- .dockerignore is mandatory. Exclude node_modules, .git, build artifacts.
Anti-Patterns
latesttag in production — pin specific versionsRUN apt-get updatewithoutapt-get installin same layer — cache becomes stale- COPY . . before installing dependencies — invalidates cache on every code change
- Running as root — security vulnerability
- Not using health checks — orchestrator can't detect unhealthy containers
