kubernetes - 在 Kubernetes 上部署和公开应用程序

问题描述

在 Ubuntu 上，我使用 minikube 在 kubernetes 上部署和公开应用程序。我遇到了如何使用和查看应用程序的问题。

我使用此链接来解决此问题。

minikube service --url $SERVICE

我希望输出显示我在 kubernetes 上部署的应用程序。

当我点击 ubuntu 终端中的链接时，谷歌浏览器的实际输出是：

This site can’t be reached 
192.168.99.108 refused to connect.
Try:
Checking the connection
Checking the proxy and the firewall
ERR_CONNECTION_REFUSED

这是 pod 定义：

解决方案

您需要使用 ip 传递 NodePort 编号才能接收响应。可以试试

kubectl get service $SERVICE --output='jsonpath="{.spec.ports[0].nodePort}"'

获取端口号？
