[Bug?]: removal of bash breaks downstream images

[josephlbarnett]

Please add the exact image (with tag) that you are using

eclipse-temurin:11-jre-alpine

Please add the version of Docker you are running

Docker version 24.0.6, build ed223bc

What happened?

Rebuilt an image that was based FROM eclipse-temurin:11-jre-alpine and started to get the attached failure.
Was able to work around this by changing a bash to an sh in our CMD, but did not expect this to disappear from beneath us. Are these sorts of changes things we should expect and we should pin to a more specific upstream tag, or is there a better recommended way of handling them (are there release notes we can subscribe to somewhere that would list out potentially breaking changes like this?)?

Thanks, appreciate what you do!

Relevant log output

/__cacert_entrypoint.sh: exec: line 30: bash: not found

Came from https://github.com/adoptium/containers/pull/460/files - that change should have been release note'd but not sure where: @gdams do you know where we output change notes like that?

Yup, also took me by surprise just now.

@gdams Is there a pull request you could link perhaps? Or another issue?
