使用kubeadm部署k8s集群00-缓存gcr.io镜像
2018/2/7
原因:kubeadm init 时,需要下载一些镜像,但国内网络原因,大家懂的,不容易下载,此时,只能去绕过它。
备注:官方在 1.5 收到阿里一位童鞋的 PR 来允许指定一个第三方的 registry 来解决上述问题,但因为时间所限,并未找到具体的操作方法。
【在国外节点上操作】
针对下述镜像:
gcr.io/google_containers/kube-apiserver-amd64:v1.9.0
gcr.io/google_containers/kube-controller-manager-amd64:v1.9.0
gcr.io/google_containers/kube-scheduler-amd64:v1.9.0

##### 清理中转用到的镜像 tag :
docker rmi $(docker images |grep opera443399 |awk ‘{print $1":"$2}‘)
