查看创建集群需要的镜像版本
kubeadm config images list [--kubernetes-version <version>]
国内拉取镜像脚本
一般而言，直接使用kubeadm拉取指定仓库地址是可以的
kubeadm config images pull --image-repository registry.aliyuncs.com/google_containers --kubernetes-version v1.18.3
下面这种是我没找到自动拉取时写的，下列脚本与以上不同的地方在于修改了镜像tag ?
#!/bin/bash

# please run kubeadm for get version msg. e.g `kubeadm config images list --kubernetes-version v1.18.3`
# then modified the Version's ENV, Saved and Run.
KUBE_VERSION=v1.18.3
