Container Registry

Azure Container Registry (ACR) is a managed service that enables customers to create and maintain private container registries that are used to store and deploy container images.

A public version of ACR, called Microsoft Artifact Registry, provides a portal through which customers can browse and download public container images and other artifacts, such as tools.

Service Overview 

ACR provides a managed container registry, which can be used to store private container images and related artifacts, such as security scan results. When deploying container-based applications, container images are stored in a registry. The container host retrieves, or pulls, images from a registry when the containers are deployed. (See “Understanding Containers and Kubernetes“.) ACR can be easier to use than creating a private registry from scratch and more secure than using public registries.

ACR can be used by Azure-hosted container services such as Kubernetes Service, Container Instances, Service Fabric, Container Apps, and IoT Edge, and by the Azure Stack HCI OS. It can also be used as a registry for orchestration software such as Kubernetes, DC/OS, and Docker Swarm, whether the hosts are deployed on-premises, in Azure, or in other clouds.
