我是k8s的新手,正在尝试在GKE上设置一个集群。我有它的工作密切,只是服务和nginx内置到前端图像,但路由是不正确的工作,所以在网上看,它明确我应该使用一个入口。我一直在尝试设置nginx入口,但一直收到404响应,我不知道我做错了什么。
我把入口从这里拉出来:

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.1.0/deploy/static/provider/cloud/deploy.yaml

字符串
并将控制器yaml设置为:

我没有错误,图像拉问题,或任何显示在终端或在GKE控制台。

Curling会得到与浏览器相同的响应:

但是ping返回find:

rtt min/avg/max/mdev = 21.119/36.551/206.584/33.645 ms


如果有人能看出我哪里做错了,请告诉我。一直在绕圈子想把我的脑袋弄明白

我认为这里的主要问题是您拼错了Ingress资源上的一些注解。
1.你写了user,你的意思是use。而不是:

nginx.ingress.kubernetes.io/user-regex: "true"

字符串
您需要:

nginx.ingress.kubernetes.io/use-regex: "true"


1.您将kubernetes拼写为kuberenetes。而不是:

nginx.ingress.kuberenetes.io/rewrite-target: /$1


您需要:

nginx.ingress.kubernetes.io/rewrite-target: /$1


有了这两个变化,事情似乎按预期进行。你可以看到我的完整测试here
