Manually installed kube-prometheus using https://github.com/prometheus-operator/kube-prometheus/tree/main/manifests without using jb.
Rule is firing:
name: KubeControllerManagerDown
expr: absent(up{job="kube-controller-manager"} == 1)
even if I create these services: https://github.com/prometheus-operator/prometheus-operator/issues/1859#issuecomment-437740104
How to debug this issue?
