This document discusses the benefits of using multi-stage Docker builds. It notes that traditional Docker builds result in large images containing build tools and files not needed for runtime. Multi-stage builds address this by allowing builders to create multiple stages, each producing a new image, to arrive at a minimal final image containing only what is needed for production. This improves build speed and produces more secure images by removing unnecessary components. Multi-stage builds can be used across many programming languages and are supported in continuous integration/deployment on platforms like Codefresh.
