一、安裝叢集網路（在vip所在節點上執行部署）

### --- 從官方地址獲取到flannel的yaml，在master2上執行

[root@k8s-master2 manifests]# mkdir flannel
[root@k8s-master2 manifests]# cd flannel
[root@k8s-master2 flannel]# wget -c https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
 

### --- 安裝flannel網路

[root@k8s-master2 flannel]# kubectl apply -f kube-flannel.yml 
podsecuritypolicy.policy/psp.flannel.unprivileged created
clusterrole.rbac.authorization.k8s.io/flannel created
clusterrolebinding.rbac.authorization.k8s.io/flannel created
serviceaccount/flannel created
configmap/kube-flannel-cfg created
daemonset.apps/kube-flannel-ds created
 

### --- 檢查

[root@k8s-master2 flannel]# kubectl get pods -n kube-system
kube-flannel-ds-lr25d                 1/1     Running   0          76s

~~~     網路也是顯示ready狀態，說明正常

[root@k8s-master2 flannel]# kubectl get nodes   
NAME          STATUS   ROLES    AGE   VERSION
k8s-master2   Ready    master   17m   v1.16.3
