我有一个奇怪的情况，我有一个 secret.env 文件，我在其中设置了所有环境变量：
秘密.env
export TWITTER_CONSUMER_KEY="something"
export TWITTER_CONSUMER_SECRET="something"
然后我构建了一个 docker 文件来导出所有变量并像这样运行应用程序：
FROM python:3.8-slim-buster
# Set the working directory to /app
WORKDIR /app
# Copy the current directory contents into the container at /app
ADD . /app
# Install the dependencies
RUN pip install -r requirements.txt
RUN find . -name \*.pyc -delete
# Export all variables
RUN /bin/bash -c "source secret.env";
# tell the port number the container should expose
EXPOSE 8083
# run the command
ENTRYPOINT ["python", "run.py"]
但是，这引发了一个关键错误：
$ docker run --name fortweet --rm -i -t fortweet:latest bash
Traceback (most recent call last):
File "run.py", line 1, in <module>
from app import socketio, app
File "/app/app/__init__.py", line 65, in <module>
app = create_app()
File "/app/app/__init__.py", line 38, in create_app
my_settings = settings.TwitterSettings.get_instance()
File "/app/app/setup/settings.py", line 47, in get_instance
TwitterSettings()
File "/app/app/setup/settings.py", line 14, in __init__
self.consumer_key = os.environ["TWITTER_CONSUMER_KEY"]
File "/usr/local/lib/python3.8/os.py", line 675, in __getitem__
raise KeyError(key) from None
KeyError: 'TWITTER_CONSUMER_KEY'
当我在我的 Windows 上运行它时，它工作正常！
有人可以帮我吗？
