【学习随手记】kubeadm 查看创建集群需要的镜像版本，附拉取镜像脚本

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 😃

# Script For Quick Pull K8S Docker Images

# 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
PAUSE_VERSION=3.2
CORE_DNS_VERSION=1.6.7

某些比较新的版本可能会没有，阿里云更新比较慢，可以去hub.docker.com去搜下图的用户上传的使用
