In my previous article I described the Docker image cache and how Docker decides that a particular layer needs to be rebuilt when you do a docker build .
Using the Docker cache efficiently can result in significantly faster build times. In some environments though, like CI/CD systems, individual builds happen ...
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= ...

--cache-from is able to solve layer caching reliably in Drone.io even when using the plugins/docker plugin to build Docker images. As a closing thought I include this oldie from xkcd. If you can save five minutes on a build that is running five times a day, you can easily spend a day or two optimizing it with --cache-from .

On a hosted agent, that build cache will be empty, as a new host is spun up for every request. The --cache-from argument allows you to tell Docker to also consider a specific image as part of it's build cache.
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 …
