通过Nginx + Gunicorn（泊坞窗撰写）服务多个Flask应用

Question

G'day 我试图向我的Nginx添加另一个服务“邮件程序”，该服务启动时没有任何错误，但是当我尝试调用我的“邮件程序”服务（http：// nginx_ip / mails / healthcheck）时，我收到了“ 404”第一个作品http：// nginx_ip / v1 / notes / login等...。我确认我的 nginx.conf 文件有一些错误。你有什么主意吗？

这是我的nginx.conf

upstream hello_flask {
    server app:5000;
}

upstream hello_flask2 {
    server mailer:5080;
}

server {

    listen 80;

    location /v1/notes {
        proxy_pass http://hello_flask;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_redirect off;
    }

      location /mails {
        proxy_pass http://hello_flask2;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_redirect off;
    }


}

routes.py

from flask import current_app as app


@app.route('/mails/healthcheck', methods=['GET'])
def healthcheck():
    return "OK", 200
