# 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 extra work to be discovery.
|
|
|
|
### create service for kube-controller-manager
|
|
1. `kubectl apply -f controller-service.yaml`
|
|
2. edit `/etc/kubernetes/manifests/kube-controller-manager.yaml` , modify or add one line `- --bind-address=0.0.0.0`
|
|
3. wait kube-controller-manager to restart
|
|
|
|
### create service for kube-scheduler
|
|
3. `kubectl apply -f scheduler-service.yaml`
|
|
4. edit `/etc/kubernetes/manifests/kube-scheduler.yaml` , modify or add one line `- --bind-address=0.0.0.0`
|
|
5. wait kube-scheduler to restart
|
|
|
|
### create service for etcd
|
|
6. `kubectl apply -f etcd-service-http.yaml`
|
|
7. 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`
|
|
8. wait etcd to restart
|
|
|
|
### create all other objects with deployment
|
|
9. 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.
|
|
|
|
|
|
10. `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.
