Timeout控制

为了避免按照程序本身的默认超时时间等待，可以加入 timeout

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: nginx-default-v2
  namespace: lizhe
spec: 
  hosts:
  - nginx-service
  http:
  - match:
    - headers:
        ver: 
          exact: v2
    timeout: 3s
    route: 
    - destination:
        host: nginx-service
        subset: v2
  - match:
    - headers:
        ver: 
          exact: v3
    redirect:
      uri: /index.html
  - route: 
    - destination: 
        host: nginx-service
        subset: v1
    timeout: 3s
