leoheng-MacBook-Pro:~ leo$ 4. build
命令解释：用于Dockerfile创建镜像
参数
--build-arg=[] :设置镜像创建时的变量；
--cpu-shares :设置 cpu 使用权重；
--cpu-period :限制 CPU CFS周期；
--cpu-quota :限制 CPU CFS配额；
--cpuset-cpus :指定使用的CPU id；
--cpuset-mems :指定使用的内存 id；
--disable-content-trust :忽略校验，默认开启；
-f :指定要使用的Dockerfile路径；
--force-rm :设置镜像过程中删除中间容器；
--isolation :使用容器隔离技术；
--label=[] :设置镜像使用的元数据；
-m :设置内存最大值；
--memory-swap :设置Swap的最大值为内存+swap，"-1"表示不限swap；
--no-cache :创建镜像的过程不使用缓存；
--pull :尝试去更新镜像的新版本；
--quiet, -q :安静模式，成功后只输出镜像 ID；
--rm :设置镜像成功后删除中间容器；
--shm-size :设置/dev/shm的大小，默认值是64M；
--ulimit :Ulimit配置。
--tag, -t: 镜像的名字及标签，通常 name:tag 或者 name 格式；可以在一次构建中为一个镜像设置多个标签。
--network: 默认 default。在构建期间设置RUN指令的网络模式
使用当前目录的 Dockerfile 创建镜像，标签为 runoob/ubuntu:v1。
docker build -t runoob/ubuntu:v1 .使用URL github.com/creack/docker-firefox 的 Dockerfile 创建镜像。
docker build github.com/creack/docker-firefox也可以通过 -f Dockerfile 文件的位置：
docker build -f /path/to/a/Dockerfile .在 Docker 守护进程执行 Dockerfile 中的指令前，首先会对 Dockerfile 进行语法检查，有语法错误时会返回：
$ docker build -t test/myapp .
