|NO.Z.00031|——————————|^^ 部署 ^^|——|Kubernetes&高可用集群.V05|——|flannel网络|

一、安装集群网络（在vip所在节点上执行部署）

### --- 从官方地址获取到flannel的yaml，在master2上执行

[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

### --- 安装flannel网络

[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

### --- 检查

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

~~~     网络也是显示ready状态，说明正常

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