3.1 开放kiali至集群外部

• 首先将istio-inressateway暴露集群外部;

  在node02的ens33网卡上面有多余的ip地址，将该地址绑定在igressgateway的svc 上面。

  kubectl edit svc istio-ingressgateway -n istio-system
  

  

• 定义kiali的ingress gateway的资源配置清单

  apiVersion: networking.istio.io/v1beta1
  kind: Gateway
  metadata:
    name: kiali-gateway
    namespace: istio-system
  spec:
    selector:
      app: istio-ingressgateway
    servers:
    - hosts:
      - "kiali.icloud2native.com"
      port:
        name: http-kiali
        number: 80
        protocol: HTTP
  ---
  

• 定义kiali的VirtualService清单

    http:
    - match:
      - uri:
          prefix: /
      route:
      - destination:
          host: kiali
          port:
            number: 20001
  

• 定义kiali的DestinationRule清单

  apiVersion: networking.istio.io/v1beta1
  kind: DestinationRule

    name: kiali-dr
    namespace: istio-system
  spec:

        name: http-80
        number: 80
        protocol: HTTP
      hosts:
      - "grafana.icloud2native.com"

          prefix: /
      route:
      - destination:
          host: grafana
          port:
            number: 3000
  

• 定义grafana的dr

  apiVersion: networking.istio.io/v1beta1
  kind: DestinationRule
  metadata:
    name: grafana
    namespace: istio-system
  spec:
    host: grafana
