If this solution doesnt helps change the docker version from docker to docker-ce

rpm -e docker-common-1.13.1-209.git7d71120.el7.centos.x86_64 docker-1.13.1-209.git7d71120.el7.centos.x86_64 docker-client-1.13.1-209.git7d71120.el7.centos.x86_64
sudo yum-config-manager –add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo yum install docker-ce

systemctl start docker
