Answer
They split build and runtime stages to create smaller production images, remove build tools, and speed up CI/CD pipelines.
Quick Answer
Multi-stage builds let you use multiple FROM stages in one Dockerfile. Build tools, compilers, and test frameworks run in early stages; only the final artifact gets copied into a clean, minimal final image. Result: production images that are tiny and contain zero build tooling — smaller, faster, more secure.
