我正在学习kubernetes,目前正在尝试创建一个带有两个路径的入口,一个在名为“java-app-service”的服务上,另一个在“test-service”上。我可以访问java-app-service,但我在测试应用程序上得到了Bad Gatheway,为什么?这里是java-app-service:

apiVersion: v1
kind: Service
metadata:
  labels:
    app: java-app
  name: java-app-service
spec:
  selector:
    app: java-app
  ports:
    - protocol: TCP
      port: 80
      targetPort: 8080
  type: NodePort

测试服务:

apiVersion: v1
kind: Service
metadata:
  labels:
    app: test-app
  name: test-service
spec:
  selector:
    app: test-app
  ports:
    - protocol: TCP
      port: 80
      targetPort: 3000
  type: NodePort

我的入口:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: java-app-ingress
status:
  loadBalancer:
    ingress:
      - hostname: my-app
spec:
  ingressClassName: nginx
  rules:
    - host: my-app
      http:
        paths:
          - path: /
            pathType: Prefix
            backend:
              service:
                name: java-app-service
                port:
                  number: 80
          - path: /test/
            pathType: Prefix
            backend:
              service:
                name: test-service
                port:
                  number: 80

服务都在这里,加上我的java-app部署:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: java-app-deployment
spec:
  replicas: 3
  selector:
    matchLabels:
      app: java-app
  template:
    metadata:
      labels:
        app: java-app
    spec:
      containers:
        - name: java-app
          image: aquatrale/demo2
          ports:
            - containerPort: 8080

test-app:

apiVersion: apps/v1
kind: Deployment
metadata:
  namespace: default
  name: test-deployment
spec:
  replicas: 5
  selector:
    matchLabels:
      app: test-app
  template:
    metadata:
      name: test-pod
      namespace: default
      labels:
        app: test-app
    spec:
      containers:
        - name: test-app
          image: aquatrale/test:latest
          imagePullPolicy: IfNotPresent
          ports:
            - containerPort: 3000

我错过了什么?

尝试1:

尝试在Services上为端口设置名称:

apiVersion: v1
kind: Service
metadata:
  name: my-app
  ...
spec:
  ports:
  - name: my-app-port
    port: 80
    targetPort: 8080

并从Ingresss中引用它的名称:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ...
  annotations:
    kubernetes.io/ingress.class: nginx
spec:
  rules:
  - host: ...
    http:
      paths:
      - path: ...
        backend:
          service:
            name: my-app
            port:
              name: my-app-port

尝试2:

尝试从第二个路径(/test/)中删除尾随的/
根据这个文档,它还应该匹配第二个服务的所有子路径,包括“主”路径(没有尾随斜杠)。
