安装旧版本docker-ce

安装kubernetes的时候1.10.x, 支持最高版本的docker版本为17.03

现在安装docker-ce的版本为18.x

所以要安装一个旧版本.

但安装的时候报错, github的issue里面有对应的解决方法

下面是引用andrewhsu的回复

A new obsoletes restriction was introduced in docker-ce 17.06.0 and it looks like the yum repo is applying it to all versions of the docker-ce indiscriminately. To work around this when installing older versions of docker-ce, you can pass a flag to ignore obsoletes:

$ yum install -y --setopt=obsoletes=0 \

  docker-ce-17.03.1.ce-1.el7.centos \

  docker-ce-selinux-17.03.1.ce-1.el7.centos
