我是Kubernetes的新手，我正试图在我们的内部计算服务系统中使用Kubernete托管一个应用程序。
由于我们的内部计算服务不支持rewrite-target注释，我不得不使用反向代理来处理重写。
所以，我的流程是：VIP->服务->Pod[具有nginx重写的Sidecar]->Pod〔应用程序容器〕
以下是清单：

我正在使用Minikube(在我的本地机器中)，当我试图点击URL时，我得到了"；404未找到"；页
这里的问题是，服务无法连接Pod〔Sidecar〕！
有人能帮忙解决这个问题吗？
提前感谢！
尝试使用：
# MacOS
minikube start --driver=docker
kubectl apply -f file-with-all-the-manifests.yaml
它对我很有用♂️.
来自同一命名空间上的调试pod：
/ # curl reportportal-ui:5000

也适用于Nginx sidecar容器：
/ # curl 127.0.0.1:8080
<!doctype html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

它可能是在您运行的任何环境中建立网络。您的内部计算系统或minikube。查看是否没有吊舱崩溃：
kubectl get pods --all-namespaces
