attach_metadata namespace doesn't exist on CRDs

[dudrv]

Documentation at https://docs.victoriametrics.com/victoriametrics/sd_configs/#kubernetes-role-pod states

_meta_kubernetes_namespace_label: Each label from the namespace object. Available when attach_metadata: {namespace: true} is set

But there seems to be no way how to add attach_metadata: {namespace: true} part to any CRD.

The problem I am trying to solve is that I want to scrape pods in namespaces having certain label. After finding out, that I cannot use labelSelector in namespaceSelector I wanted to use metadata to filter out targets, that don't have the label, but as the configuration parameter is not available, i am stuck.

After finding out, that I cannot use labelSelector in namespaceSelector

could you please share configuration you've tried?

I was just reading through documentation and I didn't find any configuration I could use:

1. VMPodScrape has namespaceSelector but that is list of names - i.e. doesn't allow for namespace matching by label
2. vmagent has parameter attach_metadata: {namespace: true}, but that is not exposed via CRD - that way I could work around first problem by dropping targets from namespaces i don't need via relabelConfig.
