Container Registry is deprecated. Effective March 18, 2025, Container Registry is shut down and writing images to Container Registry is unavailable.
gcr.io URLs hosted on Artifact Registry, including Google-owned images
with gcr.io URLs, are not affected by the Container Registry shutdown.
For more details about the Container Registry deprecation and how to migrate to Artifact Registry, see Container Registry deprecation.
Artifact Registry is the recommended service for container image storage and management on Google Cloud. Artifact Registry provides the same container management features as Container Registry and includes additional features and benefits. As a fully-managed service with support for both container images and non-container artifacts, Artifact Registry extends the capabilities of Container Registry.
Summary of new features
Artifact Registry extends the capabilities of Container Registry with the following features:
- Repository-level access control.
- Hosting artifacts in regions to reduce latency and data transfer costs, and to comply with data residency requirements.
- Streaming images to Google Kubernetes Engine and Google Cloud Serverless for Apache Spark to reduce workload startup times.
- Deploying to Cloud Run from source.
- Audit logging for repository activity.
- Enforcement of organization policy, including encryption with customer-managed encryption keys (CMEK) and location constraints.
- Scanning for OS and language package vulnerabilities in containers.
- Virtual repositories that aggregate multiple repositories behind a single host.
- Remote repositories that cache artifacts from upstream sources such as Docker Hub or Maven Central.
See the feature comparison for more details about these features.
Existing Container Registry images maintained by Google
Most Google-owned images previously hosted on Container Registry are now hosted
on Artifact Registry in gcr.io repositories. You don't need to change
the URLs to pull these images. For example, you can still use the
Cloud Build official builder images.
Cached Docker Hub images on mirror.gcr.io
Artifact Registry caches frequently-accessed public Docker Hub images on
mirror.gcr.io. For more information on using mirror.gcr.io, see
Pull cached Docker Hub images.
Feature comparison
The following table summarizes differences between Container Registry and Artifact Registry.
| Feature | Container Registry | Artifact Registry |
|---|---|---|
| Supported formats | Container images only | Multiple artifact formats, including container images, language packages, and OS packages. |
| Domain name | gcr.io |
pkg.dev
Artifact Registry can also store images for the |
| Repository modes | Not applicable |
|
| Registry creation | You create a registry host by pushing the first image to it.
Container Registry stores images in Cloud Storage buckets in your Google Cloud project and actions such as granting registry-specific permissions must be applied directly to a bucket. |
Creating a repository is a separate operation from pushing and pulling
to clearly separate repository administration from repository usage.
In Artifact Registry, there are no Cloud Storage buckets to manage in your Google Cloud projects. You perform image management actions directly on a repository. |
| Registry location | Only four multi-regional registry hosts are available in a Google Cloud project. | Create multiple, separately-controlled repositories in region or multi-region. |
| Access control |
|
|
| Authentication | Provides several authentication methods for pushing and pulling images with a third-party client. | Artifact Registry supports the same authentication methods as Container Registry. See Setting up authentication for Docker for details. |
| Customer-managed encryption keys (CMEK) | Use CMEK to encrypt the storage buckets that contain your images. | Use CMEK to encrypt individual repositories. |
| Using Google Cloud console | View and manage Container Registry images from the Container Registry section of Google Cloud console. | View a list of your Artifact Registry and Container Registry
repositories in the Artifact Registry
section of Google Cloud console. Manage your Artifact Registry
repositories and images from this page.
If you click a Container Registry repository, you are directed to the list of images in the Container Registry section of the Google Cloud console. |
| Using gcloud CLI and API commands | Uses gcloud container images commands. Commands support shortened digests. If you don't specify the
full digest string, Container Registry attempts to locate the correct image
based on the partial string.
There is no REST or RPC API for Container Registry. |
Uses gcloud artifacts docker commands. Commands don't support shortened digests.
For a comparison of Container Registry and Artifact Registry gcloud CLI commands, see the gcloud CLI command comparison. Artifact Registry provides a REST and RPC API for managing repositories and artifacts. |
| Pub/Sub notifications | Publishes changes to the gcr topic. |
Publishes changes to the gcr topic. If you create repositories
in the same project as your existing Container Registry service, your
existing Pub/Sub configuration works automatically.
To learn more, see Configuring Pub/Sub notifications. |
| Audit logging | Container Registry does not provide audit logs for registry activity. | Use Cloud Logging to track changes to your repositories. |
| Cached Docker Hub images | mirror.gcr.io is a pull-through cache that stores
the most frequently requested Docker Hub images across all users.
mirror.gcr.io is in now
hosted on Artifact Registry. |
mirror.gcr.io is in now
hosted on Artifact Registry. No action is required unless you are using
mirror.gcr.io in a VPC Service Controls perimeter. For more
information on using mirror.gcr.io in a VPC Service Controls
perimeter, see
Use Artifact Registry with VPC Service Controls. |
| VPC Service Controls | You can add Container Registry to a service perimeter. | You can add Artifact Registry to a service perimeter. |
| Metadata storage and analysis with Artifact Analysis | Scans for OS and language package vulnerabiities with on-demand scanning
in images with a supported OS. Automatic scanning only returns OS
vulnerability information.

scanning.
|
Scans for OS and lanaguage package vulnerabiities with both on-demand and
automatic scanning.

scanning.
|
| Image streaming | Unavailable | Stream images in Artifact Registry to GKE or Google Cloud Serverless for Apache Spark for faster autoscaling, faster pod startup, and reduced latency when pulling large images. |
| Cloud Run source deployment | Unavailable | Source deployment lets you use a single gcloud CLI command to build a container image from your source code, store the image in Artifact Registry, and deploy it to Cloud Run. |
| Pricing | Container Registry pricing is based on Cloud Storage usage, including storage and network data transfer. Since registry hosts are only available in multi-regions, data transfer costs include deploying images to Google Cloud | Artifact Registry has its own pricing, based on storage and network data transfer. |
| Quota | Container Registry has fixed request limits. Cloud Storage quotas also apply. For details, see the quota and limits documentation. | Artifact Registry has per-project and per-user quotas. Per-user quota is unlimited by default, but you can configure a per-user cap so that a single user does not consume too much of the project-level quota. |
