集成了一百多个最常用的Linux命令的镜像，不到2M，短小精悍我喜欢。
$docker search busybox
官方下完1.22M
$docker pull busybox:latest
运行之后会进入如下所示，可以直接输入命令，exit退出
[root@localhost test]# docker run -it busybox WARNING: IPv4 forwarding is disabled. Networking will not work. / #
一个面向安全的轻量级linux操作系统，大小5M左右，占用资源小，自带BusyBox跟包管理工具apk等。
因为小所以爱可以直接运行自动下载
$docker run alpine echo ‘我很小’
用time查看下载运行需要多久
[root@localhost test]# time docker run alpine echo "我很小" Unable to find image ‘alpine:latest‘ locally latest: Pulling from library/alpine Image docker.io/library/alpine:latest uses outdated schema1 manifest format. Please upgrade to a schema2 image for better future compatibility.
