Manifest examples missing from VPA documentation

[fireflycons]

It should be deduced from the new CKA domain statement Configure workload autoscaling that both VPA. and HPA can be in scope. The current documentation includes no manifest examples for VPA making any potential questions very hard to solve within the average 6 minutes per question using kubectl explain only.

Please update the docs to include some examples of common VPA scenarios.

@fireflycons you must not reveal details of the questions on any Kubernetes exam.
See https://docs.linuxfoundation.org/tc-docs/certification/lf-cert-agreement#id-2-1-confidentiality

Even if you are speculating or have learned this information from a third party who has breached the candidate agreement, we may need to delete this issue.

The idea of documenting autoscaling better is very welcome. An issue calling for more docs on VPA, without mentioning the relevance, would likely be fine.

@sftim I have not revealed any actual question, nor have I even sat this version of the exam. However you can make the leap from the statement given in the current curriculum and the change of material both in popular course providers and what is provided by Kim Wustkamp that such questions are entirely likely.

All that aside, it would be good in general to have documentation including manifest examples for any new resource that's part of the core distribution.

I have now reworded the original issue, but if you feel you must close this, then I will raise another as you suggest.

Ah, cool. The syllabus is viable grounds to improve our docs.

Aside: VPA is not part of core Kubernetes. It is an optional add-on.
