## About
|
|
|
|
GitHub Action to set up Docker [Buildx](https://github.com/docker/buildx).
|
|
|
|
This action will create and boot a builder that can be used in the following
|
|
steps of your workflow if you're using Buildx or the [`build-push` action](https://github.com/docker/build-push-action/).
|
|
By default, the [`docker-container` driver](https://docs.docker.com/build/building/drivers/docker-container/)
|
|
will be used to be able to build multi-platform images and export cache using
|
|
a [BuildKit](https://github.com/moby/buildkit) container.
