kube-scheduler

在每台master节点执行

vim /etc/kubernetes/manifests/kube-scheduler.yaml

将

--bind-address=127.0.0.1

改为

--bind-address=0.0.0.0

kube-controller-manager

vim /etc/kubernetes/manifests/kube-controller-manager.yaml

将

--bind-address=127.0.0.1

改为

--bind-address=0.0.0.0

etcd

vi /etc/kubernetes/manifests/etcd.yaml

将

--listen-metrics-urls=http://127.0.0.1:2381

改为

--listen-metrics-urls=http://127.0.0.1:2381,http://你主机的IP地址（也就是图上serviceMonitor中展示的访问不通的地址）:2381
