一、安装与使用nerdctl
containerd虽然可直接提供给终端用户直接使用，也提供了命令行工具(ctr)，但并不是很友好，所以nerdctl应运而生，它也是containerd的命令行工具，支持docker cli关于容器生命周期管理的所有命令，并且支持docker compose (nerdctl compose up)1.1安装nerdctl
下载地址：https://github.com/containerd/nerdctl/releases# 下载
[root@k8s-master ~]# wget https://github.com/containerd/nerdctl/releases/download/v2.1.2/nerdctl-2.1.2-linux-amd64.tar.gz
# 解压
[root@k8s-master ~]# tar -zxvf nerdctl-2.1.2-linux-amd64.tar.gz
nerdctl
containerd-rootless-setuptool.sh
containerd-rootless.sh
# 复制文件
[root@k8s-master ~]# mv nerdctl /usr/bin/
# 配置 nerdctl 参数自动补齐
[root@k8s-master ~]# echo 'source <(nerdctl completion bash)' >> /etc/profile
[root@k8s-master ~]# source /etc/profile
# 验证
[root@k8s-master ~]# nerdctl -v
nerdctl version 2.1.21.2命名空间
这个和K8s的名字空间不是一回事，其中default就是containerd的默认名字空间，http://k8s.io是K8s的名字空间root@k8s-03:~/bin# nerdctl ns ls

# 清理数据，它不是和Docker那样只是把标签为"none"的镜像清理掉，而是把所有没有"正在使用"的镜像清理了
[root@k8s-master ~]# nerdctl system prune -h二、nerdctl+buildkitd构建镜像
2.1buildkit介绍
buildkit 从Docker公司的开源的镜像构建工具包，支持OCI标准的镜像构建
buildkitd组成部分：
buildkitd（服务端），目前支持runc和containerd作为镜像构建环境，默认是runc，可以更换containerd。
buildctl（客户端），负责解析Dockerfile文件、并向服务端buildkitd发出构建请求。
构建镜像并推送至Harbor为例，整个服务调用过程如下：
