master ,node1安装后重新启动master,node1,node2机器

Question

我初始化的脚本
kubeadm init --kubernetes-version=1.19.3
–apiserver-advertise-address=192.168.42.101
–image-repository registry.aliyuncs.com/google_containers
–service-cidr=10.1.0.0/16
–pod-network-cidr=10.244.0.0/16
在安装master节点中，我也执行过https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml 主要是dns一直pending,执行了就是正常的了。
第一遍安
装都成功了，后面我就关了vwware虚拟机，重新开启master, node1,node2 3台虚拟机。kubectl get nodes是正常的。kubectl get pods -n kube-system就发现上面的3个pod运行不正常了。

再执行https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml 一下

  执行了。还是一个样，kube-flannel.yml 是直接下载到我本地电脑的。
