将 Django 应用程序部署到 App Engine 柔性环境

Question

我正在尝试部署 sample app to the Google App Engine Flexible Environment based on this 教程。部署有效，但是应用程序无法启动。我收到以下错误消息：

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

正如您在 GitHub 上看到的（参见上面的 link），/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]

/mysite/wsgi.py 文件如下：

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阶段，我不确定这是否是一个错误。但是，我使用的是 GitHub 的原始应用程序，没有按照官方文档进行任何更改，因此我希望它能正常工作。

感谢您的帮助。

Answer 1

尝试：

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

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

Answer 2

感谢 Adam（Google Group Forum 上的 Google Cloud Platform 团队成员）提示文件可能未部署，我从 138.0 更新了 Google Cloud SDK .0 到 141.0.0。现在一切正常，如教程中所述。

Answer 3

确保满足您的要求，即将 requirements.txt 复制到项目的根目录

https://github.com/GoogleCloudPlatform/python-docs-samples/blob/master/appengine/flexible/django_cloudsql/requirements.txt

看起来像这样

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

和运行

pip install -r requirements.txt

然后 gcloud app deploy
