1、rpm -qa | grep docker
docker-1.13.1-53.git774336d.el7.centos.x86_64
docker-client-1.13.1-53.git774336d.el7.centos.x86_64
docker-common-1.13.1-53.git774336d.el7.centos.x86_64
2、使用yum remove卸载软件
yum remove docker-1.13.1-53.git774336d.el7.centos.x86_64
yum remove docker-client-1.13.1-53.git774336d.el7.centos.x86_64
yum remove docker-common-1.13.1-53.git774336d.el7.centos.x86_64
