--------------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 <<EOF | bin/istioctl replace -f -
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 <<EOF | bin/istioctl replace -f -
apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
name: ratings
spec:
hosts:

• ratings
  http:
• fault:
  delay:

  percent: 100
  fixedDelay: 2s
  
          
  
            
          
          
          
  
            
  
            AI 代码解读
          
        
        

  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 <<EOF | bin/istioctl replace -f -
apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
name: reviews
spec:
hosts:

• reviews
  http:
• route:
  • destination:
    host: reviews
    subset: v2
    timeout: 1s
    EOF
