minikube - 啟動集群時出錯：kubeadm init 錯誤
我的環境：
$ cat /etc/redhat-release CentOS Linux release 7.5.1804 (Core) $ uname -a Linux X.X.X 3.10.0-862.11.6.el7.x86_64 #1 SMP Tue Aug 14 21:49:04 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux $我按照安裝（Linux）然後嘗試啟動它並收到以下錯誤：

請指教。

看起來 Docker 無法從中提取 Kubernetes 映像
k8s.gcr.io我會將它添加到 minikube VM 內的 docker 服務中
--insecure-registry k8s.gcr.io我很驚訝正確的 CA 證書和 docker 配置在 minikube VM 上不起作用。
