Kubernetes Istio bookinfo使minikube暂停任何请求

我一直在尝试在我的开发环境中评估Istio，但到目前为止，我还无法运行bookinfo应用程序。我下载了istio版本0.7.1，安装时没有任何问题

为了验证安装是否正常，我运行了命令watch kubectl get pod--all namespace，输出显示所有pod都正常运行

Every 2.0s: kubectl get pod --all-namespaces                              ubuntu: Tue Apr 24 04:21:00 2018

然后，我运行了命令kubectl create-fminikube的默认内存是2GB，bookinfo需要一个更大的值。尝试以以下方式启动minikube：

minikube start --memory 4096

Node: Ubuntu 17.10 VM (To be clear my laptop is running Windows and I have a VM with Ubuntu with : 8Gb of RAM, 4 Processors and 80Gb of disk)
Istio : version 0.7.1
kubectl version

minikube start --memory 4096
