Docker tags containing alpine3.11 will no longer be produced. We will not delete existing images or those tags, however, they contain unsupported builds of Alpine and .NET Core.

If you are using one of the .NET Core Alpine 3.11 tags such as 3.1-alpine3.11 or 2.1-alpine3.11, we strongly recommended that you upgrade to use an Alpine 3.12 tag such as 3.1-alpine3.12 and 2.1-alpine3.12. Alternatively you can use a floating tag for Alpine such as 3.1-alpine or 2.1-alpine. By using a floating tag, you will always be using the latest version of Alpine.

The following Docker repos have been updated:

• dotnet/core/sdk
• dotnet/core/aspnet
• dotnet/core/runtime
• dotnet/core/runtime-deps
