Docker & Containers

Package your AI app for consistent deployment

🔑 Key Concepts

Multi-stage builds — Builder stage installs deps, runtime stage copies only what's needed. Small images = fast deploys.
Docker Compose — API + vector DB + Redis + Postgres in one config. 'docker compose up' runs the full stack.
Health checks — HEALTHCHECK in Dockerfile. Load balancers need this to route traffic away from broken containers.
Secrets — API keys via environment variables, not baked into images. Use Docker secrets or .env files.

💡 Practice: Try implementing each concept yourself before moving on. Reading about RAG and building RAG are very different things.
