wget https://yum.dockerproject.org/repo/main/centos/7/Packages/docker-engine-selinux-${DOCKER_VERSION}-1.el7.centos.noarch.rpm

yum install -y libtool-ltdl policycoreutils-python

# 先安装 docker-engine-selinux，再安装 docker-engine-selinux
rpm -ivh docker-engine-selinux-${DOCKER_VERSION}-1.el7.centos.noarch.rpm
rpm -ivh docker-engine-${DOCKER_VERSION}-1.el7.centos.x86_64.rpm
