Artifact Registry is the evolution of Container Registry. As a fully-managed service with support for both container images and non-container artifacts, Artifact Registry extends the capabilities of Container Registry.
If you currently use Container Registry, use the information on this page to learn about transitioning to Artifact Registry.
Artifact Registry provides the same container management features as Container Registry. You can start transitioning your automation to use Artifact Registry for your containers.
Backwards compatibility and co-existence
You can use both Artifact Registry and Container Registry in the same
project. When you view a list of repositories with
Cloud Console, Artifact Registry also lists Container Registry
repositories in the same project.
Both services will continue to co-exist after Artifact Registry becomes generally available. To take advantage of the expanded capabilities in Artifact Registry, you can transition your containers and your automation to Artifact Registry.
After Artifact Registry becomes generally available, you will have an option to create backwards-compatible repositories. These repositories can help you perform a more gradual update to your automation for builds and deployments with support for:
gcloud container imagescommands
- Referencing the repository with a
To provide compatibility, these repositories will have some feature limitations. In particular, each backwards-compatible repository must be located in the same multi-region as a corresponding Container Registry hostname in your project.
Setting up repositories
In Artifact Registry you must create repositories before you can push images to them. So a key part of moving to Artifact Registry is setting up Artifact Registry repositories and integrating them into your CI/CD automation.
To provide greater flexibility, there are some changes in how Artifact Registry represents repositories.
- Container Registry
Each multi-regional location is associated with a single storage bucket. Organizing your images into repositories under a hostname is optional. Consider the following example that shows the image
webappin three locations:
us.gcr.io/my-project/webapp us.gcr.io/my-project/team1/webapp us.gcr.io/my-project/team2/webapp
Repositories are only an organizing mechanism and do not restrict access. Any user with access to the storage bucket for
us.gcr.ioin this project can access all versions of the
- Artifact Registry
Each repository is a separate resource in your project. Since each repository is a unique resource, you can:
- Give each repository a name, description, and labels
- Create multiple repositories in the same location
- Configure repository-specific permissions
In addition, the location of a repository can be a region or a multi-region.
These changes give you more control over your repositories. For example, if you have teams in São Paulo and Sydney, you can create a repository for each team in a region that is geographically closer than the nearest multi-regional location.
You can then grant each team with permissions to their team repository only.
See the setup guide for instructions to transition to Artifact Registry.
Pushing and pulling images
To help you adapt existing configuration, commands, and documentation designed for Container Registry, the following information compares building, pushing, pulling, and deploying images.
This section summarizes changes and improvements to Container Registry features.

methods as Container Registry. See Setting up authentication for Docker for details.
