Django – Docker – 应用程序默认凭证不可用

我想在Docker容器中使用带有Django项目的Google Cloud SDK。 假设我想使用

from google.cloud import vision from google.cloud.vision import types 

当我使用requirements.txt文件安装google-cloud出现如下所示的错误。 在没有容器的本地机器上，它正常工作。 有没有人有一个想法，我怎么能解决这个问题？

django_1 | oauth2client.client.ApplicationDefaultCredentialsError：应用程序默认凭证不可用。 如果在Google Compute Engine中运行，则可以使用它们。 否则，必须定义环境variablesGOOGLE_APPLICATION_CREDENTIALS，指向定义凭据的文件。 有关更多信息，请参阅https://developers.google.com/accounts/docs/application-default-credentials 。

更新我在MacBook上工作，我发现在这个网站上 ：

 docker run --rm -it -v ~/.config/gcloud:/.config/gcloud google/cloud-sdk 

在这一刻，我得到如下所示的错误。 任何想法如何解决这个问题？

问题是你正在挂载文件夹/而不是/root/configuration将被检查

更改

 docker run --rm -it -v ~/.config/gcloud:/.config/gcloud google/cloud-sdk 

至

 docker run --rm -it -v ~/.config/gcloud:/root/.config/gcloud google/cloud-sdk 

如果您使用docker-compose，则将其添加到特定服务器的yaml中

 volumes: - ~/.config/gcloud:/root/.config/gcloud
