Docker Layer Caching
Enable Docker Layer Caching by adding a single line in GitHub Actions. This GitHub Action speeds up the building of docker images in your GitHub Actions workflow.
You can run docker build and docker-compose build in your GitHub Actions workflow using the cache with no special configuration, and it also supports multi-stage builds.
This GitHub Action uses the docker save / docker load command and the @actions/cache library.
The author had not considered a large number of layers to be cached, so those versions process all layers in parallel.
(#12)
Please update to version v0.0.5 with limited concurrency to avoid overloading the cache service.

By default, the cache is separated by the workflow name. You can also set the cache key manually, like the official actions/cache action.
