Alpine Floating Tags Updated to Alpine 3.23

[lbussell]

In December 2025, Alpine 3.23 container images were published. For today's January 2026 .NET release, all Alpine floating tags have been update to point to Alpine 3.23 instead of Alpine 3.22 according to our tagging policy.

Per the .NET Docker platform support policy, Alpine 3.22 images will no longer be maintained starting on April 14, 2026 (3 months after Alpine 3.23 images were released).

Details

Please review the Alpine 3.23 changelog for more details on changes that were made in this version of Alpine.

The affected floating tags use this naming pattern:

• <version>-alpine (e.g. 10.0-alpine)
• <version>-alpine-<variant> (e.g. 10.0-alpine-extra)
• <version>-alpine-<arch> (e.g. 10.0-alpine-amd64)
