buildctl和nerdctl 安装配置 一、安装与使用nerdctlcontainerd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 NAME CONTAINERS IMAGES VOLUMES LABELS buildkit 0 0 0 buildkit_history 0 0 0 default 0 1

[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：2.2安装buildkit软件包下载地址：https://github.com/moby/buildkit/releases[root@master ~]# wget
