使用K8s入口与Istio网关？

Question

kind: Deployment
apiVersion: apps/v1
metadata:
  name: echo
spec:
  replicas: 1
  selector:
    matchLabels:
      app: echo
  template:
    metadata:
      labels:
        app: echo
    spec:
      containers:
        - name: echo
          image: mendhak/http-https-echo
          ports:
            - containerPort: 80
---
kind: Service
apiVersion: v1
metadata:
  name: echo
spec:
  type: ClusterIP
  selector:
    app: echo
  ports:
    - port: 80
      name: http

这起作用了

apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: gateway
spec:
  selector:
    istio: ingressgateway
  servers:
    - port:
        number: 80
        name: http
        protocol: HTTP
      hosts:
        - '*.dev.example.com'
---
apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: echo
spec:
  hosts:
    - echo.dev.example.com
  gateways:
    - gateway
  http:
    - route:
        - destination:
            host: echo

这不是

kind: Ingress
apiVersion: extensions/v1beta1
metadata:
  name: echo
spec:
  rules:
    - host: echo.dev.example.com
      http:
        paths:
          - backend:
              serviceName: echo
              servicePort: 80

您的入口需要有一个注释:kubernetes.io/ingres.class:istio。

取决于您正在使用的Istio版本，它可能无论如何都无法工作。目前有一个关于Ingress在最新的驱动程序中不工作的公开问题，听起来它可能已经坏了一段时间。
