安装Docker 1.12

Kubernetes 1.6还没有针对docker 1.13和最新的docker 17.03上做测试和验证，所以这里安装Kubernetes官方推荐的Docker 1.12版本。

yum install -y yum-utilsyum-config-manager \ --add-repo \ https://docs.docker.com/v1.13/engine/installation/linux/repo_files/centos/docker.repoyum makecache fast

查看版本：

yum list docker-engine.x86_64 --showduplicates |sort -rdocker-engine.x86_64 1.13.1-1.el7.centos docker-maindocker-engine.x86_64 1.12.6-1.el7.centos docker-maindocker-engine.x86_64 1.11.2-1.el7.centos docker-main

安装1.12.6：

yum install -y docker-engine-1.12.6systemctl start dockersystemctl enable docker

打包rpm

yum install git -y git clone https://github.com/kubernetes/release && cd release/rpm && ./docker-build.sh
