yum -y install kubernetes
报错
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
原因是因为之前安装过docker，版本冲突原因，解决方法如下：
查询安装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
卸载
[root@901-22 ~]# yum -y remove containerd.io.x86_64 docker-ce.x86_64 docker-ce-cli.x86_64
重新安装
