我有一个简单的 k3s 集群，根据文档安装了 Ambassador 入口控制器

当我尝试通过浏览器访问该服务时，我只会收到一条“上游不健康”的消息。

这些是我的配置：

$ kubectl describe svc web-test-service
Name:              web-test-service
Namespace:         default
Labels:            app=web-test

$ kubectl describe svc ambassador

$ kubectl get po

ambassador-58b444b8-wfclj   1/1     Running   0          24m

我检查了服务日志，应用程序已启动并正在运行并正在侦听端口 8080。
