安装docker-machine

版本号更加情况修改，我使用V0.16.0

base=https://github.com/docker/machine/releases/download/v0.16.0 &&
curl -L $base/docker-machine-$(uname -s)-$(uname -m) >/tmp/docker-machine &&
install /tmp/docker-machine /usr/local/bin/docker-machine

创建虚拟机


docker-machine create --driver virtualbox default

[root@localhost ~]# docker-machine ls
