This is no longer the correct repo - see adoptium/containers instead

[cher1705]

ok...I already knew this place...but I can't see alpine / ubi and so on ... that's why I have asked

and thanks for the quick response

Yeah, that repo doesn't appear to have JRE releases or alpine builds just yet. Does that mean that these have been dropped and we cannot get 11.0.12 patch releases to https://hub.docker.com/r/adoptopenjdk/openjdk11/ for now?

It's been a month or so since 11.0.12 was released, and the security baseline version did appear to change at least for the Oracle builds so wondered if there is something critical in there that we need (need to dig a bit deeper, admittedly).

statement on alpine is here: docker-library/official-images#10662 (comment)

@timja Thanks, I have seen that. I suppose my perspective was that it felt a bit disconcerting to me for it to be vague since it seemed to represent an implicit drop in support for patches of an LTS release which were previously supported (well, at least the Docker incarnation of it). Perhaps that's not accurate though, and I just haven't found/read the right info :-)

Anyone found a roadmap/approx timeline for the JRE builds, slim builds and/or alternate distros to come back - and which ones are almost certainly being dropped for now, so people can change directions.

I understand that these things take time to transition though.

I don't think they plan to do that, adoptium/containers#4 (comment)

You're recommended to use one of the existing and then copy it into your distribution, I did this for Jenkins in: jenkinsci/docker#1185

Ahh thanks for that link - that's helpful. We did that multi-stage approach already for a special case AL2 image we had, but I believe Alpine is a bit clunkier due to the need to also have glibc there replacing musl (as was done in the earlier Adopt images); and was trying to avoid having to figure out how to do that the "right" way. Will take a look though.

Yeah, alpine example: jenkinsci/docker#1186

Liberica has the alpine musl port backported as well if that's of interest to you:
https://hub.docker.com/r/bellsoft/liberica-openjdk-alpine
(I've never tried it, it just came up in my searches on this topic)

Might be the lesser of two evils to just switch to adoptopenjdk/openjdk11:jdk-11.0.12_7-alpine - I didn't realise there were actually JDK builds for Alpine published, as means its just the JRE is missing. That's a bit confusing to me - I thought that was what this PR was going to do. 😅

Will keep hunting. Thanks again for sharing!

[chadlwilson]

For anyone who comes across it, I now see most of the relevant info regarding JREs is at adoptium/temurin-build#2683 and adoptium/adoptium-support#333

[karianna]

docker-library/official-images#10779 is the PR for the alpine glibc base images.
