docker版本升级

docker的版本变化：

Docker从1.13.x版本开始，版本分为企业版EE和社区版CE，版本号也改为按照时间线来发布，比如17.03就是2017年3月，有点类似于ubuntu的版本发布方式。

企业版自然会提供一些额外的服务，当然肯定也是收费的。企业版说明https://blog.docker.com/2017/03/docker-enterprise-edition/

社区版分为stable和edge两种发布方式。

stable版本是季度发布方式，比如17.03, 17.06, 17.09

edge版本是月份发布方式， 比如17.03, 17.04......

Docker的linux发行版的软件仓库从以前的https://apt.dockerproject.org和https://yum.dockerproject.org变更为目前的https://download.docker.com, 软件包名字改为docker-ce和docker-ee。

docker仓储配置：

sudo yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo yum makecache fast
