既然 `RUN` 就像 Shell 脚本一样可以执行命令，那么我们是否就可以像 Shell 脚本一样把每个命令对应一个 RUN 呢？比如这样：
```dockerfile
FROM debian:jessie
FROM debian:stretch
RUN apt-get update
RUN apt-get install -y gcc libc6-dev make
RUN wget -O redis.tar.gz "http://download.redis.io/releases/redis-3.2.5.tar.gz"
RUN apt-get install -y gcc libc6-dev make wget
RUN wget -O redis.tar.gz "http://download.redis.io/releases/redis-5.0.3.tar.gz"
RUN mkdir -p /usr/src/redis
RUN tar -xzf redis.tar.gz -C /usr/src/redis --strip-components=1
RUN make -C /usr/src/redis

上面的 `Dockerfile` 正确的写法应该是这样：
```dockerfile
FROM debian:jessie
FROM debian:stretch
RUN buildDeps='gcc libc6-dev make' \
RUN buildDeps='gcc libc6-dev make wget' \
&& apt-get update \
&& apt-get install -y $buildDeps \
&& wget -O redis.tar.gz "http://download.redis.io/releases/redis-3.2.5.tar.gz" \

&& tar -xzf redis.tar.gz -C /usr/src/redis --strip-components=1 \
&& make -C /usr/src/redis \

或许你已经注意到了，`docker build` 还支持从 URL 构建，比如可以直接从 Git repo 中构建：
```bash
$ docker build https://github.com/twang2218/gitlab-ce-zh.git#:8.14
docker build https://github.com/twang2218/gitlab-ce-zh.git\#:8.14
$ docker build https://github.com/twang2218/gitlab-ce-zh.git#:11.1

这行命令指定了构建所需的 Git repo，并且指定默认的 `master` 分支，构建目录为 `/8.14/`，然后 Docker 就会自己去 `git clone` 这个项目、切换到指定分支、并进入到指定目录后开始构建。
