Docker Registry API

Note: Artifact Registry is currently in beta. As the evolution of Container Registry, it supports multiple artifact formats, regional repositories, and more granular access control. After it becomes generally available, Artifact Registry will replace Container Registry. Learn about transitioning to Artifact Registry.

Container Registry implements a Docker protocol so that you can push and pull images directly with Docker clients.

Google Cloud applications that typically integrate with Container Registry are configured by default to push and pull images from repositories in the same project.

In addition, you can push and pull images using:

• The docker command.
• The Docker Registry API
• Third-party applications that use the Docker Registry API to communicate with registries.

To use any of the additional options you must:

• Grant the required permissions to the service account that pushes and pulls images.
• Configure authentication with Docker. How you configure your credentials will depend on the specific client you are using. For examples of CI/CD integrations with Container Registry, see Continuous delivery tool integrations

Note: Container Registry does not support Docker chunked uploads. Some container image tools support uploading large container images with either chunked uploads or a single monolithic upload. You must use monolithic uploads when you push container images to Container Registry.

Refer to the Docker Registry API documentation for details about using the API.
