1， docker for windows 安装
2， docker machine安装
3， virtualbox + vagrant 快速搭建
- 安装centos7
mkdir centos
cd centos
#创建Vagrantfile，可以到https://app.vagrantup.com/boxes/search
vagrant init centos/7
vagrant up
vagrant ssh
- centos下安装docker，官网参考
sudo yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-engine
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager -y --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo yum install -y docker-ce docker-ce-cli containerd.io
