Question

我正在尝试在minikube中创建一个入口。我已经启用了入口添加并检查了所有相关服务，并且已经添加了pod并且正在运行。

当我创建入口时，我将其指向与入口位于同一名称空间的service.NodePort。但是，当我描述入口时，后端IP地址为<none>

这是我的部署yaml

apiVersion: v1
kind: Namespace
metadata:
  name: proxy
  labels:
   name: proxy
---
apiVersion: apps/v1beta1
kind: Deployment
metadata:
  name: deployment
  namespace: proxy
  labels:
    app: proxy
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: proxy
    spec:
      containers:
      - name: proxy
        image: wildapplications/proxy:latest
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 8080
      imagePullSecrets:
        - name: regsecret
---
apiVersion: v1
kind: Service
metadata:
  name: service
  namespace: proxy
spec:
  type: NodePort
  ports:
  - port: 8080
    targetPort: 8080
  selector:
    app: proxy
  externalName: proxy
---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress
  namespace: proxy
  annotations:
    ingress.kubernetes.io/rewrite-target: /
spec:
  rules:
  - host: echo.example.com
    http:
      paths:
      - path: /test
        backend:
          serviceName: service
          servicePort: 8080

当我描述我得到的入口时

Name:             ingress
Namespace:        proxy
Address:          192.168.99.100
Default backend:  default-http-backend:80 (172.17.0.14:8080)
Rules:
  Host              Path  Backends
  ----              ----  --------
  echo.example.com  
                    /test   service:8080 (<none>)
Annotations:
  rewrite-target:  /
Events:
  Type    Reason  Age   From                Message
  ----    ------  ----  ----                -------
  Normal  CREATE  16m   ingress-controller  Ingress proxy/ingress
  Normal  CREATE  15m   ingress-controller  Ingress proxy/ingress
  Normal  UPDATE  15m   ingress-controller  Ingress proxy/ingress

为什么入口无法解析为其上方直接创建的服务指定的后端，有什么明显的明显之处吗？

我找到了我的问题的解决方案，所以我发布以防其他人遇到类似的事情。

我试图通过我的minikube ip地址（typealias Indexed = (num: Int, index: Int) class Buffer { let ordered = PublishSubject<Int>() private var current = 0 private var buffer: [Int: Int] = [:] func onNext(_ indexed: Indexed) { self.buffer[indexed.index] = indexed.num for index in self.buffer.keys.sorted() { if index == current { ordered.onNext(self.buffer[index]!) self.buffer.remove(at: self.buffer.index(forKey: index)!) current += 1 } } } } let buffer = Buffer() buffer .ordered .subscribe(onNext: { num in print("aaab done \(num)") }) .disposed(by: disposeBag) persistMessageEventBus .mapWithIndex { (num, index) -> Indexed in return (num: num, index: index) } .flatMap({ indexed -> Observable<Indexed> in print("aaab Doing \(indexed.num)") let t2g = Observable.just(indexed).delay(Double(indexed.num), scheduler: MainScheduler.instance).do(onNext: { indexed in print("aaab Done async \(indexed.num)") }) return t2g }) .subscribe(onNext: { indexed in buffer.onNext(indexed) }) .disposed(by: disposeBag) persistMessageEventBus.onNext(2) persistMessageEventBus.onNext(4) persistMessageEventBus.onNext(1)来获取ip）来访问入口，这提供了404，因为我没有使用主机导航到它。

解决我执行的404

minikube ip

然后从浏览器导航到主机网址。

Kubernetes Ingress没有解决后端服务问题
