Multi-stage Builds

Multi-stage builds are a technique for creating Docker images that are more efficient and secure. By using multiple stages, you can break down the build process into smaller steps, which can make it easier to troubleshoot and maintain. Additionally, multi-stage builds can help to reduce the size of your final image, which can improve performance and save on storage space.

What are the benefits of using multi-stage builds?

There are several benefits to using multi-stage builds, including:

• Increased efficiency: By breaking the build process into smaller steps, multi-stage builds can make it easier to troubleshoot and maintain. Additionally, multi-stage builds can help to reduce the time it takes to build an image.
• Improved security: By isolating each step of the build process into a separate stage, multi-stage builds can help to improve security. This is because it makes it more difficult for attackers to exploit vulnerabilities in one stage of the build process to gain access to the final image.
• Reduced image size: By only including the necessary files in each stage of the build process, multi-stage builds can help to reduce the size of the final image. This can improve performance and save on storage space.
