docker-manifest-action is a simple GitHub action that combines a list of Docker manifests and merges them into one image via the docker buildx imagetools command.

As of docker-manifest-action v1, the API is stable enough to not break at all.

on:
    # ...
jobs:
    docker:
        runs-on: ubuntu-latest
        name: my ci job
        steps:
            - uses: Noelware/docker-manifest-action@v1
              with:
                  inputs: namespace/image:latest
                  images: namespace/image:latest-amd64,namespace:image/latest-arm64
                  push: true

• images was changed to tags to better reflect buildx imagetools create
• base-image was removed, use inputs instead
• extra-images was removed, use tags instead
• amend was renamed to append to better reflect buildx imagetools create

A list of Docker images thdocker buildx imagetoolsat were built from docker build into the merged manifests.

Optionally, it can be a comma-separated list (i.e, image/a:latest-amd64,image/b:latest-amd64) to create multiple final images from the given tags.

A comma-separated list of tags that will be applied into the merged manifest from inputs.

Whether if the action should push the outputs to the Docker registry.

A mapping of annotations to annotate the final, merged manifest.

This is the same syntax as the official Docker GitHub actions handles mappings of label=value.

View the docker buildx imagetools create --annotation documentation on how to format each annotation.

Sets the --append flag, which will add new sources to existing manifests.

Sets the --builder for the buildx command.
