Details

Image tags containing alpine3.20 will no longer be produced. We will not delete existing 3.20 images or tags, but they now contain unsupported builds of Alpine and .NET.

If you are using one of the Alpine 3.20 tags such as 8.0-alpine3.20 or 9.0-alpine3.20, we recommended that you upgrade to Alpine 3.21 (e.g. 8.0-alpine3.21). Alternatively, you can use a floating tag for Alpine such as 8.0-alpine or 9.0-alpine.
