我是Istio通过 bookinfo 示例应用程序了解的。此时，我正在测试基于内容的路由，作为调试过程的一部分，我必须在Istio-ingresspod 上使用 curl 命令，但它不存在（这很奇怪，因为根据 istio 站点它应该存在）我应该离线安装（不兴奋）还是应该将 pod 连接到互联网？有没有其他方法可以检查VirtualService和DestinationRule是否正常工作？

Kubernetes 版本：1.11.1

印花布版：3.1

Istio 版本：0.8.0

我的意思是我创建了VirtualService但它不起作用，我想知道如何调试它，因为 istio 官方站点中提出的方法使用 curl 命令（在istio-ingresspod 中不存在）

这是输出 kubectl get virtualservices -o yaml
