为什么 Kuberenetes kubeadm init 命令无法从存储库 k8s.gcr.io 中提取镜像

Question

我有 2 个虚拟机，分别运行一个 kubernetes 主节点和一个在本地设置的从节点。到目前为止，一切都工作正常，但当我尝试使用 kubeadm init 命令启动 master 时，突然开始出现错误。我已 cpppied 下面的错误。

shayeeb@ubuntu:~$ sudo kubeadm init
[init] using Kubernetes version: v1.11.1
[preflight] running pre-flight checks

[preflight/images] Pulling images required for setting up a Kubernetes cluster
[preflight/images] This might take a minute or two, depending on the speed of your internet connection
[preflight/images] You can also perform this action in beforehand using 'kubeadm config images pull'
[preflight] Some fatal errors occurred:

[preflight] If you know what you are doing, you can make a check non-fatal with `--ignore-preflight-errors=...`

您还可以运行以下命令而不是编写 yaml，

kubeadm init --kubernetes-version=1.11.0 --apiserver-advertise-address=<public_ip> --apiserver-cert-extra-sans=<private_ip>

如果您使用的是 flannel 网络，请运行以下命令，

kubeadm init --kubernetes-version=1.11.0 --pod-network-cidr=10.244.0.0/16 --apiserver-advertise-address=<public_ip> --apiserver-cert-extra-sans=<internal_ip>
