错误解决
原因是 containerd.io 软件包版本太低，升级下就好
通过 Docker 官网查找最新版的 containerd.io，进去后找到自己使用的 Linux 发行版本, 我这边是 Centos
https://download.docker.com/linux/
查看右侧最新日期，截至到目前，最新版本为
containerd.io-1.2.13-3.2.el7.x86_64.rpm因为我用的是 Centos8，所以使用如下命令进行安装
dnf install -y https://download.docker.com/linux/centos/7/x86_64/stable/Packages/containerd.io-1.2.13-3.2.el7.x86_64.rpm
重新执行安装脚本即可
正文完
