Clarify Alpine version support policy #2072
Description
Activity
Agree that there should be a note, along with #2011.
We only support 2 at the recommendation of the Official Images repo as there is a lot of build required for these images, and there is no upstream support or binaries for Alpine that would reduce that workload if more were added backReacted by Kai and Steffen Schroeder- changed the title
[-]Clarify support policy (for Alpine)?[/-][+]Clarify Alpine version support policy[/+]on May 21, 2026 PR #2530 submitted to add to documentation.
Problem
Specific: We were using
node:18-alpine3.17and surprised to find out, when we wanted to use the latest node version 18.20.2, that the tag had last been updated 5 month ago (src), because support was removed in #2007, even though Alpine 3.17 itself is still supported until 2024-11-22 (src).Following the link chain in the PR to previous PRs it seems the policy has been "support last two minor versions" (of at least Alpine) for some time, but this doesn't seem to be transparent in the docs (or I missed it).
So, currently it's not clear when we need to update the tag to be on a version which still receives updates.
Abstract: Support policy unclear (at least for Alpine)
Solution
Make apparent support policy "last two minor versions" or something alike transparent in the docs, probably in the README.
