Docker官网：https://docs.docker.com/install/overview/
有两个版本：
Docker is available in two editions:
- Community Edition (CE) 是免费的版本
- Enterprise Edition (EE) 是收费的版本
vagrant 安装 centos 7
vagrant + virtualBOX 安装
https://my.oschina.net/cxgphper/blog/1940644
安装Docker
系统centos7
https://docs.docker.com/install/linux/docker-ce/centos/
也可以在vagrantfile中添加安装docker shell
Vagrant up
Docker machine 在本地使用
#docker-machine create demo
Docker-machine ls
Docker-machine ssh demo 进入虚机demo
Docker-machine stop demo1
Docer-machine env demo #print出dome虚机的env
#eval $(docker-machine env demo)
#docker version #可以看到demo的虚机docker版本
搜索docker playground
https://labs.play-with-docker.com/
在 https://www.docker.com/
Docker for windows7/windows10安装 以及Docker id注册
https://blog.****.net/xzxedu/article/details/82012297
参考docker

官方给出image获取的 Docker Hub
https://hub.docker.com/search?q=&type=image
去掉sudo：
把vagrant 添加到组docker 里
#sudo groupadd docker
#sudo gpasswd -a vagrant docker
#docker version 权限还是拒绝
#sudo service docker restart 重启docker服务
#docker version
退出重新登。
#docker image ls
#docker pull hello-world 获取hello-world镜像
