1.安装（安装包分为两种）
参考地址：https://github.com/containerd/nerdctl

1.1 第一种：
Minimal: 仅包含 nerdctl 二进制文件以及 rootless 模式下的辅助安装脚本
适用场景：一般在k8s或者已安装containerd的环境中使用
$ wget https://github.com/containerd/nerdctl/releases/download/v1.4.0/nerdctl-1.4.0-linux-amd64.tar.gz
$ tar zxvf nerdctl-1.4.0-linux-amd64.tar.gz -C /usr/local/bin/
nerdctl
containerd-rootless-setuptool.sh
containerd-rootless.sh
$ nerdctl -v
nerdctl version 1.4.0
1.2 第二种
Full: 看名字就能知道是个全量包，包含containerd、runc、CNI等组件
使用场景：在单机使用 nerdctl 代替 Docker
