Docker builds, dropping java 8 and other proposals

Actually from my screenshot in the previous post I’ve misread it, those are all Java 21 JDK images (jdk21-openjdk) which we can’t use so our original issue still stands.

I’ve trawled through the tags on the Docker Hub page and the main readme seems to be correct…

Debian is only used for for JDK21 images
Ubuntu (Jammy and Focal) are used for the JRE11 images
Ubuntu (Jammy and Focal) and Amazon Linux w/ Corretto are used for the JDK11 images

There’s a GitHub issue that says the OpenJDK base images for Java versions <=17 are no longer available for them to use, which is a little strange considering Java 11 is LTS, but that’s the current state of things

Why were the Debian+JDK17 images removed in v9.0.63?

question

Hi, prior to version 9.0.63 we had images based on Debian Buster/Bullseye in com…bination with JDK17, e.g. _9.0.62-jdk17-openjdk-bullseye_. Commit 3d32b80239bf108ed9fa313d151fe7cd1943f77a removed these variants leaving only Ubuntu based variants with JDK17. Why were these variants removed? The Debian-based variants with JDK11 are still present, e.g. _9.0.63-jdk11-openjdk-bullseye_. We can't use them, however, due to an issue with cgroups v2 and Kubernetes. Will the official Debian+JDK17 images be available again or do we have to build our own?

Short version; we will have to use the Ubuntu images for the foreseeable future. I’m going to provide both versions as a choice, along with JRE and JDK for the best flexibility (size vs features).
