二部署Kubernetes
1、下载镜像3台
上传镜像压缩包、在压缩包目录下执行
2.镜像导入
vim image_load.sh 压缩包目录下
#!/bin/bash
image_path=`pwd`
for i in `ls "${image_path}" | grep tar`
do
docker load < $i
done
3台都执行注意路径
3.master节点初始化
重新初始化出错了
rm -rf /etc/cni/net.d
重新初始化
kubeadm init --kubernetes-version=1.23.5 --pod-network-cidr=10.244.0.0/16 --apiserver-advertise-address=192.168.142.151
上传yaml

node-2
