部署

添加启动脚本

[root@lab-26 ctchat]# vi /opt/kubernetes/server/bin/kube-controller-manager.sh

#!/bin/sh
./kube-controller-manager 
  --cluster-cidr 172.152.0.0/16 
  --leader-elect true 
  --log-dir /data/logs/kubernetes/kube-controller-manager 
  --master http://127.0.0.1:8080 
  --service-account-private-key-file ./cert/ca-key.pem 
  --service-cluster-ip-range 192.168.0.0/16 
  --root-ca-file ./cert/ca.pem 
  --v 2

 添加supervisor脚本

 启动服务

[root@lab-26 ctchat]# supervisorctl update
kube-controller-manager-152-106: added process group
[root@lab-26 ctchat]# supervisorctl status
etcd-server-152-106               RUNNING   pid 22579, uptime 3:49:06
