March 1, 2017

November 29, 2016

Container Registry now supports the Docker V2 image manifest, schema version 2.

August 5, 2016

The Docker client now allows users to specify a credential store, which acts as a delegate to generate the credentials that are used to authenticate requests to repositories. Container Registry's credential helper, docker-credential-gcr, simplifies authentication for all use cases, including working on a developer machine, working on a VM, and using a service account. This means you no longer have to use the Cloud SDK with Container Registry.

July, 2016

Added the Registry API _catalog command. Container Registry now implements the catalog feature as described by the Docker Registry API specification.

June 22, 2016

Container Registry now offers a Docker Hub mirror. When a user adds the --registry-mirror=https://<us|eu|asia>-mirror.gcr.io flag to their Docker daemon, any attempt to pull an image from Docker Hub results in a call to Container Registry. If the image is found in Container Registry's mirror, it is pulled from there, and no call is made to Docker Hub. If the image is not found, the client gets a 404 result and can then make a call to Docker Hub to download the image.

June 13, 2016

The Container Registry user interface now shows Docker Registry V2 image formats and V2 image digests.

November 13, 2015

Implemented V2 of the Docker Registry API. See Docker Registry HTTP API V2.

June 22, 2015

Container Registry moved from Beta to GA.

November 12, 2014

Container Registry Beta

Container Registry is a new service that provides private container repositories for GCP customers to support container development and deployment workflows. Container Registry is currently in Beta; it is suitable for experimentation and is intended to provide an early view of the production service, but customers are strongly encouraged not to run production workloads on it.
