1. 国内无法拉去Google镜像资源，导致master容器创建失败

从阿里云下载k8s镜像，并修改tag

  1. #!/bin/bash
  2. url=registry.cn-hangzhou.aliyuncs.com/google_containers
  3. version=v1.21.0
  4. images=(`kubeadm config images list --kubernetes-version=$version|awk -F '/' '{print $2}'`)
  5. for imagename in ${images[@]} ; do
  6.   docker pull $url/$imagename
  7.   docker tag $url/$imagename k8s.gcr.io/$imagename
  8.   docker rmi -f $url/$imagename
  9. done
