我正在使用 docker-compose 来构建和运行我的应用程序。
这是 docker-compose.yml：
db:
image: postgres
web:
build: .
command: sh startup.sh
volumes:
- .:/code
ports:
- "8000:8000"
links:
- db
我的 Dockerfile：
FROM python:2.7
ENV PYTHONUNBUFFERED 1
RUN apt-get update && apt-get install -y nginx
RUN mkdir /code
WORKDIR /code
ADD requirements.txt /code/
RUN pip install -r requirements.txt
ADD . /code/
因此，当我转到命令行并执行此操作docker-compose up时，它只是在那里停留Building web...了很长时间，然后最终以错误结束，说它已用完空间。vagrant vm 有 40gb，所以我不确定是什么导致所有空间被占用。

有谁知道最初采取了Building web...这么长时间的步骤？或者为什么它会占用机器上的所有空间。我只安装了几个包和 pip 库。
