接下来安装flannel network add-on：

mkdir -p ~/k8s/

wget https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel-rbac.yml

wget https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

kubectl create -f kube-flannel-rbac.yml

kubectl apply -f  kube-flannel.yml

serviceaccount “flannel” created

configmap “kube-flannel-cfg” created

daemonset “kube-flannel-ds” created

重启host后需要重新init
