docker-multiarch-build-push

docker-multiarch-build-push GitHub Action

This GitHub Action builds, scans and (optionally) pushes a multi-architecture Docker image using Docker buildx and QEMU.

It also makes use of the GitHub Actions cache to preserve the Docker build cache between runs.

See the action.yml for more information.

Usage

The following job uses this action to build and push a multi-architecture image to GitHub Packages with some standard tags (short-sha and branch name for all commits; tag if ref is a tag):
