wget https://yum.dockerproject.org/repo/main/centos/7/Packages/docker-engine-1.10.3-1.el7.centos.x86_64.rpm wget https://yum.dockerproject.org/repo/main/centos/7/Packages/docker-engine-selinux-1.10.3-1.el7.centos.noarch.rpm yum localinstall -y docker-engine* rm -f docker-engine-1.10.3-1.el7.centos.x86_64.rpm docker-engine-selinux-1.10.3-1.el7.centos.noarch.rpm systemctl start docker
