将Django应用程序部署到Deploying灵活环境中

Question

我正在尝试将样本应用程序部署到基于这教程的Google灵活环境中。但是，部署工作正常，但应用程序无法启动。我收到以下错误消息：

Updating service [default]...failed.
ERROR: (gcloud.app.deploy) Error Response: [9]

正如您在GitHub上看到的(参见上面的链接)，/app.yaml文件如下所示：

# [START runtime]
runtime: python
env: flex
entrypoint: gunicorn -b :$PORT mysite.wsgi

beta_settings:
    cloud_sql_instances: <your-cloudsql-connection-string>

runtime_config:
  python_version: 3
# [END runtime]

这样的/mysite/wsgi.py文件：

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")

application = get_wsgi_application()

由于柔性环境处于测试版，我不确定这是否是一个bug。但是，我使用的是来自GitHub的原始应用程序，没有在正式文档之后进行任何更改，所以我希望它能正常工作。

谢谢你的帮助。

Answer 1

由于Adam (谷歌集团论坛上的Google平台团队成员)暗示这些文件可能没有部署，我将Google从138.0.0更新到141.0.0。现在，一切都很好，如本教程所述。

Answer 2

尝试：

entrypoint: gunicorn -b :$PORT mysite.wsgi:application

(假设目录"mysite“与app.yaml位于同一级别。如果wsgi.py与app.yaml处于同一级别，那么只需：:$PORT wsgi:application)

Answer 3

确保您的需求得到满足，即将requirements.txt复制到项目的根目录

cloudsql/requments.txt

看上去像这样

Django==1.11.1
mysqlclient==1.3.10
wheel==0.29.0
gunicorn==19.7.1
psycopg2==2.7.1

然后跑

pip install -r requirements.txt

然后部署gcloud应用程序。
