I am using kubeadm to deploy single node kubernetes 1.11 cluster. I am unable to find servicemonitor resources.
➜ kube-prometheus git:(master) ✗ kubectl get servicemonitor
error: the server doesn't have a resource type "servicemonitor"
➜ kube-prometheus git:(master) ✗ kubectl create -f manifests/prometheus-serviceMonitor.yaml
error: unable to recognize "manifests/prometheus-serviceMonitor.yaml": no matches for kind "ServiceMonitor" in version "monitoring.coreos.com/v1"How do I enable servicemonitor with kubeadm?
The ServiceMonitor resource not part of Kubernetes itself. It is a custom resource which is part of the Prometheus operator as described here.
Make sure that you have installed the Prometheus operator (including the custom resources) beforehand to enable creating a ServiceMonitor object.
kubectl create -f manifests/prometheus-serviceMonitor.yaml try to create resource type of ServiceMontor for prometheus. But you haven't created that custom resource type yet. So first create CustomResource ServiceMonitor by using this custom resource definition(CRD). you can use following command
kubectl create -f manifests/0prometheus-operator-0servicemonitorCustomResourceDefinition.yaml
But if you are trying to put up kube-prometheus or any other sub project of prometheus-operator. You can deploy the kube-prometheus stack by running all deployments in folder level as below.
kubectl create -f manifests/
