lyft flyte在文档之后启动时出现错误？

Question

获取下面的代码，从文档中运行示例。有人知道为什么吗？

看起来像gprc。也许这是相关的？https://github.com/grpc/grpc/issues/15933

我认为问题出在FLYTE_PLATFORM_URL='127.0.0.1:30081'.Minikube运行在on上的VM中。当您运行docker run --network host时，docker守护进程与此主机- https://docs.docker.com/network/host/共享网络名称空间，因此，如果您在同一主机(而不是VM)上运行docker守护进程和Kubernetes，您应该能够使用127.0.0.1引用Kubernetes上的服务(nodeport)或入口。但是，由于minikube在osx上的虚拟机中运行，您将需要使用minikube ip来查找minikube机器的ip地址，然后设置

FLYTE_PLATFORM_URL=':30081‘
