Multi-Stage Docker file
A multi-stage Docker build is a feature in Docker that allows you to define multiple build stages in a single Dockerfile. This feature is useful for optimizing the final size of the resulting Docker image and improving the security and maintainability of the build process. With multi-stage builds, you can separate the build environment from the runtime environment, and only include the necessary artifacts in the final image. Here's a brief explanation of how multi-stage Docker builds work: Multiple Stages in a Dockerfile: A multi-stage Dockerfile includes multiple FROM statements, each representing a different build stage. Each stage is essentially a separate Docker image layer with its own set of instructions. Building Artifacts: The first stage is typically used for building the application and generating artifacts. For example, you might use a base image with development tools, dependencies, and libraries to compile code and build the application. Copy Artifacts to a Smaller ...
