Java 17 LTS - Eclipse Temurin support possible?

[wyaeld]

AdoptOpenJDK has migrated to Eclipse foundation, and the new distribution of Java is called Temurin
https://blog.adoptopenjdk.net/2021/03/transition-to-eclipse-an-update/

This is TCK certified
https://www.infoq.com/news/2021/10/adoptium-releases-temurin-jdk/

It has debian packages
https://blog.adoptium.net/2021/12/eclipse-temurin-linux-installers-available/

It has major vendor support

Founding organizations of the Adoptium Working Group include Alibaba Cloud, Huawei, IBM, iJUG, Karakun AG, Microsoft, New Relic and Red Hat. Two representatives from each organization comprise the Adoptium Steering Committee.

I would like to know if we can get support for this in distroless or not?

@loosebazooka Appu do you have an opinion on this?

[loosebazooka]

Yeah sounds good to me. Feel free to create a pr. Fyi, I'm on vacation all week and won't be able to look at anything till Feb 28th.

Ah, yeah so these don't come from debian directly yet. It's possible that there is a solution that just defines this as an external repository, but that's a lower priority for us right now.

[wyaeld]

Yes, I had noticed that, and looked into what it would take for a PR, but my unfamiliarity with the build chain here was proving difficult.

Any updates regarding this issue?

Shameless plug, the Wolfi-based java images here are built with temurin 17: https://github.com/chainguard-images/jdk/blob/main/melange.yaml#L31

Feel free to give those a try.

[rfan-debug]

Any updates regarding this issue? It seems to be a pretty legitimate ask.

What would be even more useful is to make it easy to create a smaller image using jlink and jdeps

[NikolayMetchev]

I have a working solution with the following Dockerfile:

FROM debian:stable-slim AS jre-build
WORKDIR /app

# copy the dependencies into the docker image
COPY ./build/dockerRuntimeLibs/* build/lib/
COPY ./build/classes/kotlin/main/ build/classes/
COPY ./build/classes/java/main/ build/classes/

RUN apt-get update
RUN apt-get install -y wget apt-transport-https gnupg
RUN wget -O - https://packages.adoptium.net/artifactory/api/gpg/key/public | apt-key add -
RUN echo "deb https://packages.adoptium.net/artifactory/deb $(awk -F= '/^VERSION_CODENAME/{print$2}' /etc/os-release) main" | tee /etc/apt/sources.list.d/adoptium.list
RUN apt-get update
RUN apt-get install -y temurin-17-jdk=17.0.7.0.0+7

RUN jdeps \
--ignore-missing-deps \
-q \
--multi-release 17 \
--print-module-deps \
-cp "build/lib/*" \
build/classes/com/paxos/messaging/pes/service/ApplicationKt.class > jre-deps.info

RUN jlink --verbose \
--compress 2 \
--strip-java-debug-attributes \
--no-header-files \
--no-man-pages \
--output jre \
--add-modules $(cat jre-deps.info)

# take a smaller runtime image for the final output
FROM gcr.io/distroless/java-base-debian11:nonroot

WORKDIR /app

COPY --from=jre-build /app/jre jre

COPY --from=jre-build /app/build/lib/* ./lib/

COPY ./build/dockerRuntimeLibs/ ./libs/
COPY ./build/classes/kotlin/main/ ./classes/
