IT & Software → Docker → Multi Stage Builds → Introduction to Multi Stage Builds

Overview

Multi-stage builds in Docker allow you to create smaller and more efficient images by using multiple stages in your Dockerfile. Each stage can have its own base image and dependencies, which helps in separating the build environment from the final runtime environment. This approach not only reduces the image size but also improves security and speeds up deployment. Understanding multi-stage builds is essential for optimizing your Docker workflows.
