Write a Dockerfile for your app
This prompt writes a Dockerfile for your app with a small base image, cached layers, a non-root user and a health check. It adds a docker-compose file for local development and keeps secrets out of the image.
Act as a DevOps engineer. App: [e.g. a FastAPI app with a requirements.txt] How it runs locally: [COMMANDS] Needs: [e.g. Postgres, Redis, env vars for API keys] Write a production-ready Dockerfile with a small base image, a multi-stage build if it helps, a non-root user, cached dependency layers and a health check. Add a docker-compose.yml for local development with the services it needs, and a .dockerignore. Explain each important line briefly, and keep secrets out of the image.
Check the image size with docker images. If it is over 1 GB, ask the AI to make it smaller.
