查看创建集群需要的镜像版本
[root@k8s-master-125 ~]# kubeadm config images list
国内拉取镜像脚本
可以直接使用kubeadm拉取指定仓库地址是可以的
[root@k8s-master-125 ~]# kubeadm config images pull –image-repository registry.aliyuncs.com/google_containers –kubernetes-version v1.28.2
下面是自动拉取的脚本，下列脚本与以上不同的地方在于修改了镜像tag
#! /bin/bash
# Script For Quick Pull K8S Docker Images
# please run kubeadm for get version msg. e.g kubeadm config images list --kubernetes-version v1.28.2
# then modified the Version’s ENV, Saved and Run.
KUBE_VERSION=v1.28.2
PAUSE_VERSION=3.9
CORE_DNS_VERSION=1.10.1
ETCD_VERSION=3.5.9-0
