仅仅是执行yum remove docker 后发现还是能执行docker version

    需要执行下方操作才能彻底删除docker

    1. yum remove docker \
    2.                   docker-client \
    3.                   docker-client-latest \
    4.                   docker-common \
    5.                   docker-latest \
    6.                   docker-latest-logrotate \
    7.                   docker-logrotate \
    8.                   docker-selinux \
    9.                   docker-engine-selinux \
    10.                   docker-engine
