Kubernetes SD discovery selectors do not work as expected about prometheus HOT 2 OPEN

Just for reference, I was able to filter out by node name using fields selector instead, i.e.

kubernetes_sd_configs:
  - role: pod
    selectors:
      - role: pod
        field: "spec.nodeName=$K8S_NODE_NAME"

However it worth fixing documentation (or better adding pod role to label selectors for other use-cases, for example AZ sharding).

Hi @xdrus ,
Thanks for your answer and I tried it, it worked, but one question for you - how can you know the $K8S_NODE_NAME value in advance and put it it in your config file? As you know, when you create a pod, k8s will randomly select a node to run it.
