Add multi-arch builds for hawtio-online-example images

[dale-fu]

Adding multi-arch images for arm64, ppc64le and s390x.

• Rebase to main
• Build multi-arch images for quarkus using quarkus-container-image-jib extension
• Build multi-arch images for springboot using kubernetes-maven-plugin (using ubi9/openjdk-xx images from RH)

@dale-fu Thanks for your contribution! However, there are many unrelated commits, which make it hard to review. I'd expect only 1-2 commits in the pull req. Could you please try rebasing to the latest main again cleanly only with the commits you're really making? Thank you.

This will need to be pushed to quay right? Still not very happy with having to build our own images for building - it should be provided for SB when it's officially supported.

I have switched this request to merge into the main, this should remove all of the extra commits. The multiarch-build branch wasn't synced with main.

I have updated the PR by replacing the default jkube-java-xx with the openjdk s2i image provided by RH which is available on all 4 platforms. This should remove the need to build multiarch versions of jkube-java-xx. I tested the hawtio-online-example-camel-springboot images locally and it seems to "work". But I need assistance with how it interact hawtio test suite before merging as there always seem to be an timeout issue with the test suite regarding the modified springboot image.

@dale-fu Looks great now. Unfortunately, it's diverging from main again. Could you rebase it with main and resolve conflicts?

Rebased and resolved the conflicts, but I will still need assistance with testing the modified springboot image going forward.

Thanks! Looks great to me.

I will still need assistance with testing the modified springboot image going forward.

What should we assist you on this?

@mmuzikar @phantomjinx You might want to review this (again) before merging.

@tadayosi I think the major difference between the jkube-java-xx and Red Hat's openjdk-xx image is probably the missing jolokia agent in the Red Hat images. I would probably need assistance on getting that set up with the modified Spring Boot example image. This could be one of the reason why this image is not working correctly with the OpenShift test suite.

[tadayosi]

If I'm not mistaken, I think @phantomjinx also developed a Spring Boot example for OpenShift. @phantomjinx Do you have an OpenShift example?

I have submitted a camel-quarkus example that uses maven and the quarkus OpenShift deployment extension - here.

I also have created a camel-helloworld example for Springboot, which is directed towards submitting to OpenShift.

Do they help?

I think I'm mostly focusing on multi-arching the hawtio-online-example-camel-springboot as this PR already has the hawtio-online-example-camel-quarkus multi-arched. For this, we need to change the default base image that the spring boot image is using from jkube-java-xx to ubi9/openjdk-xx which is done in this PR. But with this change though, we need to manually set up the jolokia agent similar to how it was done with the quarkus image, this is where I'm stuck for now.

[dale-fu]

I have made changed to the SpringBoot image to use the Red Hat OpenJDK base images that is multi-arch and added the jolokia agent into the container.

Thanks, looks good to me now. Let's merge it.
