我刚接触GKE和kubernetes，只是想让一个简单的项目启动并运行。下面是我在GKE中在单个集群、单个节点池和单个名称空间中尝试完成的工作：
LoadBalancer服务后面的nginx部署接受端口80上的Http流量，并将其通过端口8000传递到
前端部署（python Django）在ClusterIP服务之后，接受端口8000上的流量。
前端已成功与运行Postgres数据库的StatefulSet通信。在我将其服务从LoadBalancer切换到ClusterIP之前，看到前端成功为Http（gunicorn）提供服务。
我不知道如何正确设置Nginx配置以将流量传递到前端部署的ClusterIP服务。我所拥有的配置不起作用。
如有任何意见/建议，我们将不胜感激。以下是安装文件：
nginx -等/nginx/配置文件d/nginx配置文件

upstream front-end {
    server front-end:8000;
}

server {

    listen 80;
    client_max_body_size 2M;

    location / {
        proxy_pass http://front-end;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_redirect off;
    }

    location /static/ {
        alias /usr/src/app/static/;
    }

}
