Question

我正在尝试按照https://cloud.google.com/python/django/flexible-environment上的Google教程

在GCP上部署我的django后端rest apis

我能够成功部署示例应用，但是当我尝试部署我的django应用时，我得到以下错误：

在构建历史中，它显示了成功：

在GCP日志中，它也没有显示错误，但是＆＃34;工作人员无法启动＆＃34;：

当我尝试打开＆＃34; https://bcbackend-200008.appspot.com/＆＃34;我得到了以下信息：

尝试用＆＃34; - verbosity = debug＆＃34;运行它选项及以下是日志：

尝试在app.yaml中将--preload作为参数添加到gunicorn命令。这将在尝试启动工作人员时向您显示错误。这些错误将为您提供部署失败原因的线索。

您的app.yaml应该是这样的：

runtime: python
env: flex
entrypoint: gunicorn --preload -b :$PORT mysite.wsgi

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

runtime_config:
  python_version: 3

在谷歌云上部署Django后端会在控制台上出错，但日志中没有错误
