kubeadm拉取镜像并改名脚本

拉取镜像并改名脚本

#!/bin/bash
images=(
	kube-apiserver:v1.24.3
	kube-controller-manager:v1.24.3
	kube-scheduler:v1.24.3
	kube-proxy:v1.24.3
	pause:3.7
	etcd:3.5.3-0
	coredns:v1.8.6
)
for imageName in ${images[@]} ; do
    docker pull registry.cn-hangzhou.aliyuncs.com/google_containers/$imageName
    docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/$imageName       k8s.gcr.io/$imageName
    docker rmi registry.cn-hangzhou.aliyuncs.com/google_containers/$imageName
done

 第二种场景，由于coredns路径有变化，需要单独定义路径
