因此，我正在尝试部署一个个人网站应用程序，并将其公开到本地域(目前(，但我总是从我的nginx入口控制器收到一个502坏网关。因此，对于这样的任务，我构建了3个文件：deployment.yaml、service.yaml和ingress.yaml:
apiVersion: apps/v1
kind: Deployment

以下是我的nginx入口控制器的一些日志：

现在我正在使用minikube，因此，我的nginx入口控制器只需将其添加为插件即可进行配置。我怀疑问题出在我的入口配置上，因为我已经通过端口转发了部署的pod，并且网站显示在正确的端口上。
根据要求，以下是我的网站吊舱详细信息：

提前感谢您的帮助。
根据注释；Service清单中的targetPort和Deployment清单中的containerPort需要与容器内的服务器正在侦听的端口匹配
由于nginx默认在端口80上侦听，因此应该将其更改为端口80。否则，容器中的服务器应该更改为在不同的端口上侦听。对于nginx，这可以通过nginx.conf文件或设置NGINX_PORT环境变量来完成。看见https://hub.docker.com/_/nginx详细信息。
通常，每个pod运行一个容器，因此很少需要将端口更改为80以外的端口。
