Error: docker-ce-cli conflicts with 2:docker-1.13.1-109.gitcccb291.el7.centos.x86_64

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
原因是因為之前安裝過docker，版本沖突原因，解決方法如下：
查詢安裝docker列表
[root@901-21 ~]# yum list installed | grep docker
containerd.io.x86_64 1.2.13-3.1.el7 @docker-ce-stable
docker-ce.x86_64 3:19.03.8-3.el7 @docker-ce-stable
docker-ce-cli.x86_64 1:19.03.7-3.el7 @docker-ce-stable
卸載
[root@901-22 ~]# yum -y remove containerd.io.x86_64 docker-ce.x86_64 docker-ce-cli.x86_64
重新安裝
