Docker Multi-Stage Builds: Optimize Your Container Images

Building efficient and lightweight Docker images is crucial for performance, especially in production environments. A common problem developers face is unnecessarily large images due to redundant dependencies. Docker multi-stage builds solve this by enabling you to separate the build and runtime environments, significantly reducing image size while maintaining efficiency.

Multi-stage builds allow you to use multiple FROM statements in a Dockerfile, enabling you to: Build the application in one stage Copy only necessary artifacts to a lightweight final image This means that unnecessary dependencies, such as compilers or build tools, are not included in the final image, resulting in a smaller, more secure, and optimized container.

What are Multi-Stage Builds?**

Multi-stage builds allow you to use multiple** FROM** statements in a Dockerfile, enabling you to:

Build the application in one stage

Copy only necessary artifacts to a lightweight final image

This means that unnecessary dependencies, such as compilers or build tools, are not included in the final image, resulting in a smaller, more secure, and optimized container.
