README.md

monitoring kubernetes control plane with plugin prometheus

if your control plane is in pod, for example, you use kubeadm build k8s cluster. Then kube-controller-manager, kube-scheduler and etcd need some extrac work to be discovery.

create service for kube-controller-manager

kubectl apply -f controller-service.yaml
edit /etc/kubernetes/manifests/kube-controller-manager.yaml , modify or add one line - --bind-address=0.0.0.0
wait kube-controller-manager to restart

create service for kube-scheduler

kubectl apply -f scheduler-service.yaml
edit /etc/kubernetes/manifests/kube-scheduler.yaml , modify or add one line - --bind-address=0.0.0.0
wait kube-scheduler to restart

create service for etcd

kubectl apply -f etcd-service-http.yaml
edit /etc/kubernetes/manifests/etcd.yaml , modify - --listen-metrics-urls=http://127.0.0.1:2381 to - --listen-metrics-urls=http://0.0.0.0:2381
wait etcd to restart

create all other objects with deployment

edit deployment.yaml and modify it with your own configure.

i. replace ${CATEGRAF_NAMESPACE} which located in ClusterRoleBinding part

ii. replace ${NSERVER_SERVICE_WITH_PORT} which located in ConfigMap part config.toml and in_cluster_scrape.yaml

if you choose etcd-service.yaml with https mode, then kubectl apply -f etcd-service.yaml.

iii. replace {data of your etcd ca file} {data of your etcd client cert file} {data of your etcd client key file} in ConfigMap etcd-pki.
kubectl apply -f deployment-etcd-http.yaml -n monitoring

Make sure that deployment.yaml always appears with etcd-service.yaml and deployment-etcd-http appears with etcd-service-http.yaml. They cannot be apply at the same time.
