Name Reservation on Azure Container Registry

Fri, 02 Aug 2024 22:36:28 Z

What's changing? Starting August 1st, Azure Container Registry (ACR) will update its behavior regarding the deletion and re-creation of registries. ACR will prevent the reuse of a subdomain name, e.g. abc123.azurecr.io, for a period after the resource is deleted. This updated behavior enhances security and prevents subdomain takeovers by automatically reserving registry names during the creation of the ACR resource, without requiring any additional action or configuration from customers. Once a resource name is reserved, it remains reserved from the moment of creation and throughout an extended period following the deletion of the resource (referred to as a cooldown period). During this cooldown period, subscriptions not associated with the original Azure AD tenant that created the resource will be unable to use the same name for a new registry. After the cooldown period concludes, the name reservation is lifted, allowing any subscription to create a registry with the previously reserved name. Customer impact Most customers will not be impacted by this update. If you delete a registry, you can create a new one with the same name within the cooldown period, provided the subscription belongs to the same Azure Active Directory (AAD) tenant. This ensures a seamless experience for customers who routinely create --> delete --> recreate resources with the same name within the same AAD tenant for testing and production workflows. The name reservation feature guarantees that customers have exclusive rights to a resource name between its deletion and subsequent recreation, preventing other customers from claiming the same name during this interval.

Announcing support of OCI v1.1 specification in Azure Container Registry

Fri, 28 Jun 2024 02:26:29 Z

The Open Container Initiative (OCI) community recently released OCI Image spec v1.1.0 and Distribution spec v1.1.0. Azure Container Registry (ACR) has supported OCI specifications v1.1.0 since its first release candidate in Jan 2023. Today, we announce support for the latest stable release v1.1.0, which provides a production-ready support for OCI artifacts in addition to container images. ACR has passed the OCI conformance test and is now certified by the OCI community as an OCI-v1.1 compliant registry. The test report is available on the OCI-Conformant Products page. By supporting the new version of OCI, ACR can store, distribute, and discover non-container content as OCI artifacts in addition to container images, which expands the possibilities of what can be stored in a container registry. ACR can now be used for generic content management enabling centralized access control and enhanced supply chain security. How OCI Spec v1.1 support benefits ACR customers Three major capabilities are now supported in ACR: Establish relationships between container images and artifacts. For example, associate supply chain artifacts such as SBOMs, signatures, vulnerability scanning reports with a container image, as shown by the referrers panel in the ACR portal below. Package, store, and distribute generic non-container artifacts as OCI artifacts in ACR, such as Helm Charts, Kubernetes manifest files, WASM modules, OPA bundles, Bicep files. Discover and query artifact relationships. Distribute a graph of artifacts across registries and recursively delete a graph of artifacts. See Listing Referrers concept for details. Enrich Containers Supply Chain Security for ACR OCI Artifacts empower users to publish and store associated content alongside container images in ACR. Containers Secure Supply Chain initiatives require the distribution of supply chain artifacts like signatures, vulnerability reports, SBOMs, and attestations alongside container images in
