Ingress-Nginx 安装
目录配置一个 Web 服务器或者负载均衡器比想象的难。大多数 Web 服务的配置文件非常相似。有些应用需要一些奇怪的需求,但是在大多数的情况下,可以使用相同的逻辑以达到预期的效果。
Ingress 资源体现了这一思想,ingress 控制器处理了上述奇怪的需求。
Ingress 控制器是一个守护进程,作为一个 Pod 部署,它监视 Apiserver 的 ingresses 端点以获取 ingress 资源的更新。

部署测试应用
kubectl apply -f ./
查看 Ingress
kubectl get ingress
# 查看详细信息
kubectl describe ingress nginx-ingress
验证 Ingress
通过外网访问域名加端口,此处为 test.test.com:30080。
