Kubernetes入口控制器-错误：ImagePullBackOff

我无法让控制器工作。尝试了很多次，但仍然得到

错误：ImagePullBackOff

我有没有别的选择，或者知道为什么失败了

    kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/nginx-0.27.0/deploy/static/mandatory.yaml

它失败是因为kubernetes无法下载指定的映像。查看事件部分

警告失败3s kubelet未能提取映像“quay.io/kubernetes入口控制器/nginx入口控制器：主”：rpc错误：代码=未知描述=来自守护程序的错误响应：Gethttps://quay.io/v2/: net/http：在等待连接时取消了请求（在等待标头时超出了Client.Timeout）

可能您没有internet连接，或者此映像不存在。您可以尝试从您的计算机运行

docker pull quay.io/kubernetes ingress controller/nginx ingress controller:master

，

我必须为专用子网创建一个nat网关，然后它开始工作
