Builders contributed by the public are available in the Cloud Builders Community repo.

Each builder includes a cloudbuild.yaml that will push your images to Artifact Registry in addition to Google Container Registry.

The provided cloudbuild.yaml assumes your project has set up a multi-region Artifact Registry Docker repositories called ga and that is setup for us, europe, and asia multi-regions (i.e.,,

To file issues and feature requests against these builder images, create an issue in this repo. If you are experiencing an issue with the Cloud Build service or have a feature request, e-mail or see our Getting support documentation.

Alternative Official Images

Most of the tools in this repo are also available in official community-supported publicly available repositories. Such repos also generally support multiple versions and platforms, available by tag.

The following official community-supported images are compatible with the hosted Cloud Build service and function well as build steps; note that some will require that you specify an entrypoint for the image. Additional details regarding each alternative official image are available in the for the corresponding Cloud Builder.

Future Direction

You may have already noticed that most of the images in this repo now provide notices to the above alternative images. For the hosted Cloud Build service, we are formulating plans surrounding both improved support for existing cloud-builder images and documentation for alternative community-supported images that may be more appropriate for some users. Both this page and the related open issues will be updated with details soon.
