Test ARM64 architecture - operator and builder pods

[squakez]

We need to test the work done in a ARM64 Kubernetes cluster.

I managed to deploy camel-k 2.0 on an arm64 using camel-k-client-2.0.0-linux-arm64.tar.gz on a Raspberry 4 (with ubuntu server + minikube + docker). My feedback is:

• I could not install with helm chart, but I suspect that's because I don't really know how to configure it
• By default any container image dependency (operator image and base image) pull was a non arm64 one. I had to specify both on install:

kamel install --operator-image apache/camel-k:2.0.0-arm64 --base-image eclipse-temurin:17@sha256:f84e436a00db070dd6df8206b3800b8e7799e13a9f75a96581e425707672d193

This behavior could be the result of an incomplete kubernetes configuration on my minikube. Or it could also be a result of :
1 - For the operator image: we declare by default camel-k:2.0.0, and this tag doesn't exists as an "arm64" arch
2 - For the base image : maybe spectrum has a default configuration for the arch version

Still, with these modifications I managed to run successfully a basic integration.

Working with camel-k 2.0.0, 2.1.0 and 2.2.0nightly on OCI arm64 cluster (Ampere A1 nodes).
Same as above, I had to specify the operator-image and base-image.

kamel install --operator-image=apache/camel-k:2.1.0-arm64 --base-image=docker.io/eclipse-temurin:17.0.9_9-jre@sha256:e530452bd0b0678cdcbb86d2fe86bbee6a2972c723c8040ccc00ca64c76df0ba

Further evidences needed, please let me know, would be happy to share.

Thanks for sharing! @niamR are you using the default publishing strategy (Spectrum) or any other strategy by any chance?

[squakez]

@gansheer maybe the configuration above could be something we should document in the official doc page? we may also have a look at github actions as in https://github.blog/2023-10-02-introducing-the-new-apple-silicon-powered-m1-macos-larger-runner-for-github-actions/ and see if we are able to add a simple smoke test as well.

@squakez Both are great ideas. I'll look into it.

@squakez Only tested with default so far, but I can give a try with buildah as we were using it in earlier versions.

No thanks, buildah was deprecated so it does not make sense. I was speaking with @gansheer right now on fixing the documentation. For now it was good enough you manage to test and provide the feedback it's working, thanks a lot!
