前言
因为需要安装minikube，其中有Docker版本要求，当前版本太低了，需要升级。

yum安装有可能无法安装最新版本，因为yum库相对官网会滞后一些。
安装最新版本
这种情况下，需要对原有docker进行卸载

sudo yum remove docker.xxxx

================================================================================
To run Docker as a non-privileged user, consider setting up the
Docker daemon in rootless mode for your user:
dockerd-rootless-setuptool.sh install
Visit https://docs.docker.com/go/rootless/ to learn about rootless mode.
To run the Docker daemon as a fully privileged service, but granting non-root
users access, refer to https://docs.docker.com/go/daemon-access/
WARNING: Access to the remote API on a privileged Docker daemon is equivalent
to root access on the host. Refer to the 'Docker daemon attack surface'
documentation for details: https://docs.docker.com/go/attack-surface/
