Azure Container Registry

Part of the Azure suite of products from Microsoft, Azure Container Registry is a registry of Docker and Open Container Initiative (OCI) images, with support for all OCI artifacts. Users can build, store, secure, scan, replicate, and manage container images and artifacts with a fully managed, geo-replicated instance of OCI distribution. Connect across environments, including Azure Kubernetes Service and Azure Red Hat OpenShift, and across Azure services like App Service, Machine Learning, and Batch.

It features:

• Geo-replication to more efficiently manage a single registry across multiple regions
• OCI artifact repository for adding Helm charts, Singularity support, and new OCI artifact-supported formats
• Automated container building and patching including base image updates and task scheduling
• Integrated security with Azure Active Directory (Azure AD) authentication, role-based access control, Docker Content Trust, and virtual network integration

The solution aims to enable fast, scalable retrieval of container workloads. Azure Container Registry handles private Docker container images as well as related content formats, such as Helm charts, OCI artifacts, and images built to the OCI image format specification.
