【问题描述】：
我想设置一个 Ingress，它将流量路由到我的底层服务。不幸的是，我在部署 ingress-controller-deployment.yaml 时遇到错误，我不知道为什么...带有 ingress-controller 的 pod 立即崩溃，并显示错误消息“CrashLoopBackOff”。
据我了解，Ingress-Control 必须部署在 Pod 中，并且可以通过 ingress-svc 访问该 pod。 ingress-svc 似乎可以工作，但 Pod 崩溃了。在入口控制器工作后，我需要一个定义路由和所有内容的附加文件。但我看不出没有工作且可部署的入口控制器继续下去的意义。

【问题讨论】：
-
在部署它之前，我创建了一个名为“ingress”的命名空间，并在这个命名空间中创建了 pod 和服务。
-
尝试从 pod 中获取日志？
-
日志显示“未知标志：--admin-backend-svc”，所以我认为这与我的参数有关。你知道它有什么问题吗？
-
你的意思是
--default-backend-service？
