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/
所以，当我进入命令行并执行docker-compose up时，它只是在那里停留Building web...很长一段时间，然后终于完成了错误，说它已经用完了空间。流浪者vm有40gb所以我不确定是什么会导致所有的空间被占用。

有谁知道最初采用Building web...步骤的原因是什么？或者为什么它会占用机器上的所有空间。我只安装了一些软件包和pip库。
答案 0 :(得分：2)
在创建Dockerfile之前，您是否以mkdir xxx ; cd xxx开头？
我想你有一条消息“上传上下文”。
从https://github.com/docker/docker/issues/2342中提取“客户端是tar /压缩你执行docker build的目录（和所有子目录）。是的，没错。如果你在你的根目录中执行它，你的整个驱动器将得到tar然后发送到码头守护进程。“
