Feature: In-cluster exporter configuration

[hrytsai]

Is your feature request related to a problem? Please describe. We run kor outside of the cluster with option provided below and got expected result: list of unused configmaps,secrets and pvc's in namespace kor configmap,secret,persistentvolumeclaim -n kor-test-namespace And now we want to reproduce this scenario but in cluster with export mode.

Describe the solution you'd like Possibility to configure kor to export prometheus metric only from 1 namespace and reduce list of resources, for example only for: configmap,secret,persistentvolumeclaim in "In cluster" mode ? Something like: kor exporter -n columbus-data-platform-dev -r configmap,secret,persistentvolumeclaim (List of included resources, by default it can be: all)

Describe alternatives you've considered A clear and concise description of any alternative solutions or features you've considered.

Additional context We want use kor in environment where each project is isolated in own Project\Namespace in OpenShift 4.x platform and should keep tracking unused resources separately.

@yonahd can I be assigned to this?

[yonahd]

@Yuni-sa I believe namespaces are already supported, so just resources are missing

[Yuni-sa]

@yonahd ,Yes it seems they do work as intended, I think I would add the functionality using GetUnusedMulti().

what do you think would be better:

kor exporter svc,ing,pod -n namespace or kor exporter -r svc,ing,pod -n namespace

[yonahd]

I actually think the proper setup may be

kor svc, ing -n namespace -exporter

But using our current code we can do it with -r
