Releases · docker/build-push-action

v2 of this action includes significant changes and now uses Docker Buildx. It extends the docker build command named buildx with the full support of the features provided by Moby BuildKit builder toolkit. This includes multi-arch build, build-secrets, remote cache, etc. and different builder deployment/namespacing options.

It works with 3 new actions (login, setup-buildx and setup-qemu) that we have created. It's also rewritten as a typescript-action to be as closed as possible of the GitHub Runner during its execution (#71 #92).

Upgrade notes and many usage examples have been added to handle most use cases.
