提示：本规划直接使用裸磁盘完成。

1.3 安装glusterfs

# yum -y install centos-release-gluster

# yum -y install glusterfs-server

# systemctl start glusterd

# systemctl enable glusterd

提示：建议所有节点安装。

1.4 添加信任池

[root@k8snode01 ~]# gluster peer probe k8snode02

[root@k8snode01 ~]# gluster peer probe k8snode03

[root@k8snode01 ~]# gluster peer status #查看信任池状态

[root@k8snode01 ~]# gluster pool list #查看信任池列表

提示：仅需要在glusterfs任一节点执行一次即可。

1.5 安装heketi

[root@k8smaster01 ~]# yum -y install heketi heketi-client

5 - --metric-resolution=30s

6 - --kubelet-insecure-tls

7 - --kubelet-preferred-address-types=InternalIP,Hostname,InternalDNS,ExternalDNS,ExternalIP #添加如上command

8 ……

2.3 正式部署

[root@k8smaster01 1.8+]# kubectl apply -f .

[root@k8smaster01 1.8+]# kubectl -n kube-system get pods -l k8s-app=metrics-server
