1. 前言本文详细介绍如何使用 kylin v10 iso 文件构建出 docker imagedocker 版本为 20.10.7。2. 构建 yum 离线源2.1. 挂载 ISO 文件mount Kylin-Server-V10-GFB-Release-030-ARM64.iso /media2.2. 添加离线 repo 文件在/etc/yum.repos.d/下创建kylin-local.repo并添加如下内容[kylin-local]name Kylin Localbaseurl file:///media/gpgcheck 0enabled 12.3. 生成元数据缓存dnf clean all dnf makecache3. 构建系统环境3.1. 创建系统安装目录mkdir -p /opt/kylin-minimal3.2. 安装最小系统dnf groupinstall Minimal --installroot /opt/kylin-minimal3.3. 验证系统环境执行chroot /opt/kylin-minimal命令进入最小系统的根目录执行ll命令查看目录结构。[rootnode0 /]# lltotal 16lrwxrwxrwx 1 root root 7 Apr 2 2021 bin - usr/bindr-xr-xr-x 7 root root 4096 Jan 3 08:58 bootdrwxr-xr-x 2 root root 42 Jan 3 08:57 devdrwxr-xr-x 88 root root 8192 Jan 3 08:58 etcdrwxr-xr-x 2 root root 6 Apr 2 2021 homelrwxrwxrwx 1 root root 7 Apr 2 2021 lib - usr/liblrwxrwxrwx 1 root root 9 Apr 2 2021 lib64 - usr/lib64drwxr-xr-x 2 root root 6 Apr 2 2021 mediadrwxr-xr-x 2 root root 6 Apr 2 2021 mntdrwxr-xr-x 2 root root 6 Apr 2 2021 optdr-xr-xr-x 2 root root 6 Apr 2 2021 procdr-xr-x--- 2 root root 140 Jan 3 08:59 rootdrwxr-xr-x 16 root root 281 Jan 3 08:56 runlrwxrwxrwx 1 root root 8 Apr 2 2021 sbin - usr/sbindrwxr-xr-x 2 root root 6 Apr 2 2021 srvdr-xr-xr-x 2 root root 6 Apr 2 2021 sysdrwxrwxrwt 2 root root 6 Jan 3 08:58 tmpdrwxr-xr-x 12 root root 192 Jan 3 08:55 usrdrwxr-xr-x 19 root root 332 Jan 3 08:56 var如果显示以上目录结构则说明最小系统环境安装成功。4. 构建 docker 镜像4.1. 打包系统安装目录tar -C /opt/kylin-minimal -cvpf /opt/kylin-minimal.tar .4.2. 创建镜像cat /opt/kylin-minimal.tar | docker import - kylin-minimal:v10根据官方文档介绍从零构建镜像只有 2 种方式FROM scratch和using tar。FROM scratch是构建一个空白的镜像没有任何内容。而using tar是基于 tar 包构建的镜像。上述命令是从 kylin-minimal tar 包构建 docker 镜像。镜像名称为kylin-minimal标签为v10。4.3. 查看镜像docker images ls -a--------------------REPOSITORY TAG IMAGE ID CREATED SIZEkylin-minimal v10 4746e82d9656 1 days ago 2.0GB卦邮瞬赐
