【问题描述】：
我一直在 docker 环境下开发一个 web 应用程序。这样一来，容器中views.py访问其他文件的方法就失败了。以下是名为“web”的容器运行时的日志
而且，demo/demo_app_views.py 是
class TestViews(TemplateView):
template_name='top.html'
with open('usr/src/demo/data/a', 'rb') as data:
b = pickle.load(data)
elder_brother=b['1']
def get_context_data(self, **kwargs):
context=super().get_context_data(**kwargs)
context['brother']=elder_brother
return context
top=TestViews.as_view()
当然，我确认了“web”容器中“data”文件夹中存储的文件“a”
而 Dockerfile 是
FROM python:3.7-alpine
WORKDIR /usr/src/demo
RUN mkdir /usr/src/demo/staticfiles
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1
RUN apk update \ && apk add postgresql-dev gcc python3-dev musl-dev
RUN pip install --upgrade pip
COPY ./requirements.txt .
RUN pip install -r requirements.txt
COPY ./entrypoint.sh .
COPY . .
ENTRYPOINT ["/usr/src/demo/entrypoint.sh"]
和... Docker-compose.yml 是
version: '3.7'
services:
web:
build: ./demo
command: gunicorn demo.wsgi:application --bind 0.0.0.0:8000
volumes:
- ./demo/:/usr/src/demo:cached
- static_volume:/usr/src/demo/staticfiles
expose:
- 8000
env_file:
- ./base.env
depends_on:
- db
db:
image: postgres:11.4-alpine
volumes:
- postgres_data:/var/lib/postgresql/data/
environment:
- POSTGRES_USER=project_demo
- POSTGRES_PASSWORD=project_demo
- POSTGRES_DB=project_demo_dev
nginx:
build: ./nginx
volumes:
- static_volume:/usr/src/demo/staticfiles
ports:
- 1337:80
depends_on:
- web
volumes:
postgres_data:
static_volume:
以及docker-compose up -d --build之后的移位日志

我不擅长docker，所以请告诉我如何访问文件'a'，它是字典类型的文件，而不是数据库
谢谢
【问题讨论】：
-
您能否提供一个minimal reproducible example 来展示您如何构建和运行您的容器？您能否将这些日志和错误消息作为文本而不是终端窗口的屏幕截图提供？
-
对不起，我添加了最少的代码和日志（可以吗？）。我希望你能提供明智的答案。
-
open('usr/src/demo...')没有前导斜杠会将其解释为相对于当前目录，这可能不是您的意思。这在没有 Docker 的普通 Python 虚拟环境中是否有效？ -
感谢大卫。你说的很对，能解决困扰我几天的问题。所以我会发布答案。
