Microsoft›Microsoft› offers Azure Container Registry

Azure Container Registry is a registry of Docker and Open Container Initiative (OCI) images, with support for all OCI artifacts. It lets teams build, store, secure, scan, replicate, and manage container images and artifacts through a fully managed, geo-replicated instance of OCI distribution. The service connects across environments such as Azure Kubernetes Service and Azure Red Hat OpenShift, and across Azure services including Azure App Service, Azure Machine Learning, and Azure Batch.

Capabilities include fast retrieval of private Docker images and related content such as Helm charts and OCI artifacts, Azure Container Registry Tasks for offloading Docker builds and automating base-image updates, multi-master geo-replication, private-network access via Azure Virtual Network integration, Docker Content Trust signing, and vulnerability scanning through Microsoft Defender for Containers. These features make Azure Container Registry a direct competitor to Docker Hub for developers storing and sharing container images.
