在生产系统中，您应该安装特定版本的 Docker CE，而不是始终使用最新版本。列出可用版本。此示例使用 sort -r 命令按版本号（从最高到最低）对结果进行排序，并且已被截断。
注：此 yum list 命令仅显示二进制软件包。如果还需要显示 源软件包，请从软件包名称中省略 .x86_64。
$ yum list docker-ce.x86_64 --showduplicates | sort -r
docker-ce.x86_64 17.06.0.el7 docker-ce-stable
yum install docker-ce-<VERSION>
systemctl start docker
