Aug 29, 2017 · docker build is not using it's cache. docker build -f Dockerfile . generates the same output that this does: docker build -f Dockerfile --no-cache . I am modifying the Dockerfile, adding commands at the end of the file. So the previous layers should be cached and valid.
Jun 18, 2020 · The Docker build process may take some time to finish. It may download base images, copy files, and download and install packages, just to mention a few common tasks. This is the reason why docker build uses a cache. In this tutorial, we’ll learn more about the build process and when it’s better to avoid the cache. 2. About the Docker Build ...
May 22, 2020 · If the objective is just to build only one final image, there is no problem because docker will handle by itself. Docker will use caches from each stage to optimize image building. Remember that for each stage, we should avoid cases that trigger docker to rebuild everything (as described in 1 and 2 ). If we want to build both 3 images to reuse.

The --cache-from command line option in the docker command allows you to build a new image using a pre-existing one as the cache source. You will see this in ...
Speed up your Docker builds with –cache-from. Using the Docker cache efficiently can result in significantly faster build times. In some environments though, like CI/CD systems, individual builds happen independent of each other and the build cache is never preserved. Every build starts from zero which can be slow and wasteful.

If we delete the image from the local cache, the subsequent build starts from scratch, since Docker can’t use layers that aren’t there:
To use an image as a cache source, cache metadata needs to be written into the image on creation. This can be done by setting --build-arg BUILDKIT_INLINE_CACHE= ...
