What is Azure Private Link for Azure Container Registry, and how does it enhance container security? Azure Private Link for Azure Container Registry (ACR) is a feature that enhances the security of container workloads by allowing you to access your container registry over a private and dedicated network connection instead of going over the public internet. It creates a private endpoint within your Azure Virtual Network (VNet) for your ACR instance, ensuring that data traffic between your virtual network and the container registry remains within the Azure backbone network.
