其它 docker build 的用法::

    1. 直接用 Git repo 进行构建
    $ docker build https://github.com/twang2218/gitlab-ce-zh.git#:8.14

    2. 用给定的 tar 压缩包构建
    $ docker build http://server/context.tar.gz

    3. 从标准输入中读取 Dockerfile 进行构建
    $ docker build - < Dockerfile
    或
    $ cat Dockerfile | docker build -

    4. 从标准输入中读取上下文压缩包进行构建
    $ docker build - < context.tar.gz
