Is your feature request related to a problem? Please describe.

Users report they would like to selectively monitor kubernetes data, be it specific pods, namespaces.

Describe the solution you'd like

The k8sobjects receiver has a neat set of filters that seem to invite a great deal of flexibility and would be reusable with the k8s cluster receiver. The idea would be to reuse the logic and user configuration.

Describe alternatives you've considered

@atoulme I am working on a filtering mechanism for mdatagen which would work k8sclusterreceiver too. Basically:

    receivers:
      k8s_cluster:
        collection_interval: 10s
        node_conditions_to_report: [Ready, MemoryPressure]            
        allocatable_types_to_report: [cpu, memory]                    
        resource_attributes:                                                                      
          k8s.pod.name:
            enabled: true 
            exclude:
              #- strict: "kube-apiserver-kind-control-plane"
              - regexp: "kube-.*"
              - regexp: "coredns-.*"
              - strict: "coredns"
              - strict: "kindnet-mpb2p"

Let me know if this works for you.

Sounds like this enhancement is supported by code owners. Implementation details are still being discussed, but we can remove needs triage.

FYI filtering mechanisms landed a while back, you can now filter like this:

receivers:
  k8s_cluster:
    collection_interval: 10s
    allocatable_types_to_report: [cpu, memory]
    resource_attributes:
      k8s.namespace.name:
        metrics_exclude:
          - regexp: kube-.*
          - strict: default

Let me know if doesn't fit your use case, otherwise we can close this
