Comment 2 Junqi Zhao 2021-04-16 01:49:11 UTC
tested with 4.6.0-0.nightly-2021-04-15-200627
pod label exists for kube_pod_info is expected, no instance label for it
search kube_pod_info{namespace="openshift-monitoring"}, result
        "metric": {
          "__name__": "kube_pod_info",
          "container": "kube-rbac-proxy-main",
          "created_by_kind": "StatefulSet",
          "created_by_name": "prometheus-k8s",
          "endpoint": "https-main",
          "host_ip": "",
          "job": "kube-state-metrics",
          "namespace": "openshift-monitoring",
          "node": "qeci-19120-hsqfv-worker-a-rd8dz.c.openshift-qe.internal",
          "pod": "prometheus-k8s-0",
          "pod_ip": "",
          "priority_class": "openshift-user-critical",
          "service": "kube-state-metrics",
          "uid": "169f1be3-de29-4f40-bc67-843b10344140"

kube_pod_info{container="kube-rbac-proxy-main", created_by_kind="DaemonSet", created_by_name="node-exporter", endpoint="https-main", host_ip="", job="kube-state-metrics", namespace="openshift-monitoring", node="ip-10-0-130-185.us-east-2.compute.internal", pod="node-exporter-x2bw5", pod_ip="", priority_class="system-cluster-critical", service="kube-state-metrics", uid="c407cd8e-de07-4c10-b203-935874306853"}

the instance and pod labels are absent for other kube_* metrics, example
        "metric": {
          "__name__": "kube_node_role",
          "container": "kube-rbac-proxy-main",
          "endpoint": "https-main",
          "job": "kube-state-metrics",
          "namespace": "openshift-monitoring",
          "node": "qeci-19120-hsqfv-worker-c-64tjw.c.openshift-qe.internal",
          "role": "worker",
          "service": "kube-state-metrics"
