dockerfile命令
1、FROM(指定基础镜像)
FROM < image>:< tag>
2、MAINTAINER(指定镜像创建者信息)
MAINTAINER
3、RUN（运行命令）
RUN可以运行任何被基础image支持的命令。
例如： RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai
4、ENV（设置环境变量）
例如：ENV LANG en_US.UTF-8
5、WORKDIR（切换目录）
相当于cd命令，对RUN,CMD,ENTRYPOINT生效。
6、CMD（设置容器启动时执行的操作）
例如：CMD $CATALINA_HOME/bin/startup.sh && tail -F $CATALINA_HOME/logs/catalina.out
7、EXPOSE（指定容器需要映射到宿主机器的端口）
例如：EXPOSE 8080 9090
8、VOLUME（指定挂载点)
例如：VOLUME $CATALINA_HOME/webapps $CATALINA_HOME/logs $CATALINA_HOME/conf
下面是一些dockfile例子
