python - google.auth.exceptions.DefaultCredentialsError：在 Docker-compose 中找不到文件 /home/technophile/snap/skype/common/xyz.json

问题描述

我有一个用 python 编写的应用程序，我把它放在一个 dockerfile 和 docker-compose.yml 中。独立运行时的python文件执行完美，但是当我使用'sudo docker-compose up'运行它时，它会导致错误：当文件本身存在时找不到文件。这是我的 Docker-compose

version: '3.7'
services:
  project-name:
    build: ./
    environment:
      GOOGLE_APPLICATION_CREDENTIALS: "${GOOGLE_APPLICATION_CREDENTIALS}"
    command: python3 main.py

这是错误：

Traceback (most recent call last):
project-name_1  |   File "main.py", line 9, in <module>
project-name_1  |     client = storage.Client()
project-name_1  |   File "/usr/local/lib/python3.7/site-packages/google/cloud/storage/client.py", line 126, in __init__

在运行 python 文件之前，我已经导出了这个 xyz.json 文件并且 python 文件运行良好。但是当我尝试使用 docker-compose 运行它时，问题就出现了。我什至创建了环境变量，但这也没有解决。请帮帮我！谢谢

解决方案

所以我终于找到了解决方法。通过将 Json 文件保存在 Dockerfile 所在的同一文件夹中并向 Dockerfile 添加一个COPY xyz.json xyz.json，它就像一个魅力。
