Microsoft is committed to making Azure Container Registry (ACR) best-in-class for the storage and distribution of container images. Following this commitment, we’re excited to announce the public preview of Caching for ACR. Once configured, Caching for ACR allows you to cache container images from Docker Hub and Microsoft Artifact Registry in your own ACR instance. This helps you continue using the best in public content and add the speed and reliability of using it from your own networks.
Caching for ACR is a new feature added to Azure Container Registry (ACR) currently in preview that allows users to cache container images from Microsoft Artifact Registry and Docker Hub.
Caching container images have three main benefits:
Caching for ACR is part of a larger solution to make your upstream content more performant and reliable, and part of your larger secure software supply chain work. If you’d like to learn more about proper usage of upstream artifacts in your infrastructure, see Manage Public Content with Azure Container Registry. In addition to using Caching for ACR, Microsoft suggests you use authenticated pulls for upstream content in line with the industry move to a stronger set of relationships across your supply chain. You can also learn more about Docker Hub and Docker Official images here, and Docker Rate limits here.
The Public Preview for Caching for ACR is currently only available in the Azure Portal. The CLI version of Caching for ACR will be available in March of 2023. Caching for ACR supports both authenticated and unauthenticated pulls. If you’d like to try out Caching for ACR, please visit our documents page here.
