This alert fires when the hostpath provisioner (HPP) Operator is down.
The HPP Operator deploys and manages the HPP infrastructure components, such as the daemon set that provisions hostpath volumes.
The HPP components might fail to deploy or to remain in the required state. As a result, the HPP installation might not work correctly in the cluster.
Configure the HPP_NAMESPACE environment variable:
$ HPP_NAMESPACE="$(kubectl get deployment -A | grep hostpath-provisioner-operator | awk '{print $1}')"
Check whether the hostpath-provisioner-operator pod is currently running:
$ kubectl -n $HPP_NAMESPACE get pods -l name=hostpath-provisioner-operator
Obtain the details of the hostpath-provisioner-operator pod:
$ kubectl -n $HPP_NAMESPACE describe pods -l name=hostpath-provisioner-operator
Check the log of the hostpath-provisioner-operator pod for errors:
$ kubectl -n $HPP_NAMESPACE logs -l name=hostpath-provisioner-operator
