--------------istio配置案例官方-------------------------------------
1.请求路由：
bin/istioctl create -f samples/bookinfo/routing/route-rule-all-v1.yaml
bin/istioctl replace -f samples/bookinfo/routing/route-rule-reviews-test-v2.yaml
https://istio.io/docs/tasks/traffic-management/request-routing/

2.流量分配：
bin/istioctl replace -f samples/bookinfo/routing/route-rule-reviews-50-v3.yaml
https://istio.io/docs/tasks/traffic-management/traffic-shifting/

3.请求超时：
https://istio.io/docs/tasks/traffic-management/request-timeouts/

将请求路由到reviews服务的v2 ，即调用ratings服务的版本

cat <apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
name: reviews
spec:
hosts:

- reviews

http:

• route:

  • destination:

    host: reviews
    subset: v2

    EOF

复制
为ratings服务调用添加2秒延迟：

cat <apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
name: ratings
spec:
hosts:

• ratings
  http:

• fault:
  delay:

  percent: 100
  fixedDelay: 2s

  route:

  • destination:

    host: ratings
    subset: v1

    EOF

在浏览器中打开Bookinfo URL（http：// $ GATEWAY_URL / productpage）

您应该看到Bookinfo应用程序正常工作（显示评级星标），但每次刷新页面时都会有2秒的延迟。

现在为reviews服务调用添加1秒的请求超时

cat <apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
name: reviews
spec:
hosts:

• reviews
  http:

• route:

  • destination:

    host: reviews
    subset: v2

    timeout: 1s

  EOF
