THIS IS AN IMPORTANT ANNOUNCEMENT: Microsoft is now publishing .NET Core container images to Microsoft Container Registry (MCR).

Note that Microsoft will continue to maintain Docker Hub repo pages so that you can discover and learn about .NET Core images. The Docker Hub website URLs you’ve used for Microsoft repos will continue to work, and forward to updated locations on Docker Hub.

Important :

• Microsoft also made other changes to the images we publish, described in this post.
• You will need to change FROM statements in Dockerfile files and docker pull commands as a result of these changes. 3.0 references need to be changed now. Most 1.x and 2.x usages can be changed over time. The new tag scheme is decribed in this post and are provided at the microsoft-dotnet-core repo, Microsoft new home on Docker Hub.
