Azure Container Registry is a managed, private Docker registry service based on the open-source Docker Registry 2.0. Create and maintain Azure container registries to store and manage your private Docker container images and related artifacts.
Use Azure container registries with your existing container development and deployment pipelines, or use Azure Container Registry Tasks to build container images in Azure. Build on demand, or fully automate builds with triggers such as source code commits and base image updates.
ACR Use Cases
Pull images from an Azure container registry to various deployment targets:
Scalable orchestration systems that manage containerized applications across clusters of hosts, including Kubernetes, DC/OS, and Docker Swarm.
Azure services that support building and running applications at scale, including Azure Kubernetes Service (AKS), App Service, Batch, Service Fabric, and others.

ACR SKUs
Azure Container Registry is available in multiple service tiers (also known as SKUs). These tiers provide predictable pricing and several options for aligning to the capacity and usage patterns of your private Docker registry in Azure.
ACR Authentication
There are several ways to authenticate with an Azure container registry, each of which is applicable to one or more registry usage scenarios.
Recommended ways include
· Authenticate to a registry directly via individual login
· Applications and container orchestrators can perform unattended, or "headless," authentication by using an Azure Active Directory (Azure AD) service principal
ACR Cost
ACR have multiple SKUs and all those SKUs have their own pricing.
