按百度出来的文章安装k8s，报错

Error: docker-ce conflicts with 2:docker-1.13.1-208.git7d71120.el7_9.x86_64
Error: docker-ce-cli conflicts with 2:docker-1.13.1-208.git7d71120.el7_9.x86_64
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

原因是之前安装了docker冲突了，卸载即可。

yum list installed | grep docker

yum remove -y docker-ce*

再次安装k8s节点成功
