setup-docker-caching

Set up Docker Buildkit in GitHub Actions to use the new experimental GitHub Actions cache backend:

• docker/buildx#535
• moby/buildkit#1974

This action won't be necessary once those pull requests are included in official releases of Docker.

Usage

In a GitHub Actions workflow:

jobs:
build:
steps:
- uses: benesch/setup-docker-caching@master
- run: docker buildx build --cache-from type=gha --cache-to type=gha PATH
