Nginx 502 Плохой шлюз - gcp

2 голосов
/ 20 июня 2020

Я пытаюсь развернуть свой Django веб-сайт в облаке Google с помощью учебника (https://cloud.google.com/python/django/appengine#cloud -console ). Мой веб-сайт работает без сбоев на локальном хосте, а также на Heroku (бесплатно). Но когда я пытаюсь развернуть свой веб-сайт на GCP, развертывание завершается без ошибок. Но доступ к веб-сайту по ссылке, предоставленной GCP, дает мне ошибку 'nginx 502 Bad Gateway'.

Я полагаю, ошибка связана с тем, что он прослушивает 'http://0.0.0.0: 8081 ' . Может ли кто-нибудь помочь.

Ниже мои журналы:

Отслеживание с веб-сайта GCP.

Спасибо Эд. Кенберс, я исправил свою проблему. Ниже приведены шаги по устранению проблемы.

  1. Создайте файл main.py в root каталоге, где присутствует app.yaml, и добавьте, как показано ниже: 

    from <your app name>.wsgi import application
app = application

  2. В файле app.yaml добавьте строку ниже: 

    entrypoint: gunicorn -b :$PORT <your app name>.wsgi

  3. В файле setttings.py в РАЗРЕШЕННЫЕ ХОЗЯЙСТВА добавьте ссылку на свой веб-сайт GCP, которая появится, когда вы разверните приложение, например «Развернутая служба [по умолчанию] на [https: // <имя вашего проекта> .el.r.appspot.com]» 

    ALLOWED_HOSTS = ["< your project name >.el.r.appspot.com",]
