为什么从 docker 文件构建会占用所有磁盘 space？
Why does building from a docker file take up all the disk space?
我正在使用 docker-compose 构建和 运行 我的应用程序。
这里是 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，它只是在那里停留了很长时间说 Building web... 然后最终以错误说它有 运行 来自 space。 vagrant 虚拟机有 40gb，所以我不确定是什么导致所有 space 被占用。

有谁知道最初 Building web... 的步骤是什么？或者为什么它会占用机器上的所有 space。我只安装了一些包和 pip 库。
在创建 Dockerfile 之前，您是否以 mkdir xxx ; cd xxx 开头？
我想你有消息 "uploading context"。
摘自 https://github.com/docker/docker/issues/2342 "the client is tar/compressing the directory (and all subdirectories) where you executed docker build. Yeah, that's right. If you execute this in your root directory, your whole drive will get tar'd and sent to the docker daemon. "
