创建Dockerfile
首先，创建目录mongo,用于存放后面的相关东西。
root@web3:~$ mkdir -p ~/mongo ~/mongo/db
db目录将映射为mongo容器配置的/data/db目录,作为mongo数据的存储目录
进入创建的mongo目录，创建Dockerfile

root@web3:~/mongo$ docker build -t mongo:3.2 .创建完成后，我们可以在本地的镜像列表里查找到刚刚创建的镜像
root@web3:~/mongo$ docker images mongo:3.2 REPOSITORY TAG IMAGE ID CREATED SIZE mongo 3.2 282fd552add6 9 days ago 336.1 MB
查找Docker Hub上的mongo镜像
