Is this an advantage of multi-stage builds?

Solution: better caching when building Docker images

Show Suggested Answer Hide Answer
Suggested Answer: B

Better caching when building Docker images is not an advantage of multi-stage builds. Multi-stage builds are a feature that allows you to use multiple FROM statements in a single Dockerfile. Each FROM statement begins a new stage of the build, with its own base image and instructions. You can selectively copy artifacts from one stage to another, leaving behind everything you don't want in the final image. The advantages of multi-stage builds are:

Reducing the size of the final image by removing unnecessary dependencies or intermediate files.

Improving the security of the final image by minimizing the attack surface and avoiding leaking secrets.

Simplifying the development workflow by using different tools or environments in different stages. Better caching when building Docker images is not an advantage of multi-stage builds, as it depends on other factors, such as the order and content of the instructions in each stage, the availability and freshness of the base images and intermediate layers, and the use of build arguments or environment variables that may invalidate the cache.
