Multi-Stage Build
Multi-Stage Docker Build
Definition
A multi-stage Docker build uses multiple FROM statements in a single Dockerfile to separate build-time dependencies from the final runtime image. Build tools, compilers, and test dependencies exist only in intermediate stages and are discarded in the final image.
This produces minimal, secure production images without complex external build scripts.
Can this ship? Are we exposed? Can you prove it?
Every CISO is asking these three questions. We answer them with facts, not guesses, from repository to runtime.
