I am not sure that's correct. Documentation seems to hint that multi-stage build help with caching: https://docs.docker.com/build/cache/#use-multi-stage-builds
A. Multi-stage builds in Docker offer better caching mechanisms when building Docker images, which is indeed an advantage. This approach allows Docker to cache the results of individual stages in the build process. If a particular stage hasn't changed (for example, the dependencies installation step), Docker can reuse the cached layer from a previous build instead of executing the instructions again. This can significantly reduce build times, especially for complex builds where certain steps (like installing dependencies) do not change often but take a considerable amount of time to complete.
Multi-stage builds are not primarily designed to improve caching. Docker's layer caching works the same way in both single-stage and multi-stage builds.
Caching can help you improve build times and performance because you only build the layer that changed, not the entire project.
