Google Cloud Artifact Registry is a fully managed, universal package repository for storing, managing, and securing build artefacts and dependencies. It is the successor to Container Registry (GCR) and supports multiple artefact formats — Docker containers, language-specific packages, and OS packages — in a single, unified service.
Artifact Registry replaces the older Container Registry with a more capable and secure service:
| Feature | Container Registry (GCR) | Artifact Registry |
|---|---|---|
| Formats | Docker only | Docker, Maven, npm, Python, Go, Apt, Yum, Helm, KubeFlow |
| Repository model | Per-project, per-region | Named repositories with fine-grained IAM |
| IAM | Bucket-level (GCS-based) | Repository-level and artefact-level |
| Vulnerability scanning | Basic | Integrated with Container Analysis and Binary Authorization |
| Cleanup policies | Manual | Automated cleanup policies |
| Virtual repositories | Not supported | Supported (aggregate multiple repos) |
| Remote repositories | Not supported | Supported (proxy external registries) |
Standard repositories store artefacts that you upload:
# Create a Docker repository
gcloud artifacts repositories create my-docker-repo \
--repository-format=docker \
--location=europe-west1 \
--description="Production Docker images"
