先检查静态文件下面的
kube-controller-manager.yaml kube-scheduler.yaml 文件 里面的是--address=127.0.0.1改成 --address=0.0.0.0
[root@k8s-master my]# ls /etc/kubernetes/manifests/
etcd.yaml kube-apiserver.yaml kube-controller-manager.yaml kube-scheduler.yaml
保存自动更新静态Pod
**但是改完并没有自动发现 **
ServiceMonitor是通过Service来监控的因此添加Service
[root@k8s-master kube-prometheus]# kubectl get svc -n kube-system
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kube-dns ClusterIP 10.96.0.10 <none> 53/UDP,53/TCP,9153/TCP 307d
kubelet ClusterIP None <none> 10250/TCP,10255/TCP,4194/TCP 5d21h
具体可以参照官网的这个图
找到kubernetesControlPlane-serviceMonitorKubeScheduler.yaml 这个文件
