Python 烧瓶在使用入口的Minikube垃圾连接上的应用

我有一个在端口5000上运行python flask应用程序的复制pod。下面是我的配置和详细信息

[ec2-user@ip-172-31-1-120 ~]$ cat tree_management/application/*.yml
apiVersion: apps/v1

            name: tree-service
            port:

    app: tree-management
  ports:
    - protocol: TCP
      port: 5000
      targetPort: 5000

应用程序在pod中运行良好，就像我在pod中执行kubectl exec以点击api url一样，然后它会给我输出。 下面是一些kubectl输出

也尝试了下面的卷曲组合，但都失败了

  curl http://local.ec.org:5000
  curl http://local.ec.org
  curl http://local.ec.org/tree
  curl http://local.ec.org/tree -H local.ec.org
  curl http://local.ec.org -H local.ec.org
  curl http://local.ec.org/ -H local.ec.org
  curl http://local.ec.org/tree -H local.ec.org
  curl http://192.168.49.2:5000/tree -H Host:local.ec.org

你能帮我一下吗

更新1 在做了一些配置更改之后，我可以看到我是否点击了下面的URL，然后请求将转到nginx，但不确定它为什么返回502坏网关

curl http://local.ec.org/tree

Nginx上的错误。我不知道为什么nginx无法连接上游

你试过

http://192.168.49.2:31893/tree

？这就是minikube实际给你的URL。@coderanger是的，刚试过，但nginx给出了404..Hi@AshifNataliya，我可以在你的

ingress nginx控制器中看到。您是否使用了
minikube隧道
？如果您想在Minikube中使用ingress控制器，可以通过命令添加：
Minikube插件启用ingress
。启用ingress加载项后，特别说明：
启用加载项后，请运行“minikube tunnel”，您的ingress资源将在“127.0.0.1”上可用。
。看看类似的问题。@MikołajGłodziak是的，我已经启用了ingress插件。我以前没有运行过minikube隧道。我刚试过，但没用。也尝试了127.0.0.1的curl，但仍然失败502意味着没有现成的豆荚。检查吊舱是否在启动时崩溃。
