基于系统iso构建docker基础镜像

确定宿主机器(linux)

[root@kylin ~]# cat /etc/kylin-release
Kylin Linux Advanced Server release V10 (Tercel)
[root@kylin ~]# uname -a
Linux kylin 4.19.90-23.8.v2101.ky10.x86_64 #1 SMP Mon May 17 17:08:34 CST 2021 x86_64 x86_64 x86_64 GNU/Linux
[root@kylin ~]#

编辑repo

[root@kylin ~]# cat /etc/yum.repos.d/kylin_x86_64.repo 
###Kylin Linux Advanced Server 10 - os repo###

构建docker镜像

在指定目录中生成根目录文件

[root@kylin ~]# cd / 
[root@kylin ~]# mkdir /ky10-docker-server 
[root@kylin ~]# yum -y --installroot=/ky10-docker-server install yum

验证和更新/ky10-docker-server目录下的软件配置

[root@kylin ~]# chroot /ky10-docker-server
bash-5.0# pwd
/
bash-5.0# ls
bin  boot  dev  etc  home  lib  lib64  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var
bash-5.0# exit

将/ky10-docker-server目录打包成docker基础镜像

[root@kylin ~]# cd /ky10-docker-server/ 
[root@kylin ~]# tar -cvpf /root/system.tar --directory=/ky10-docker-server/ --exclude=proc --exclude=sys --exclude=dev --exclude=run --exclude=boot .

docker测试

将docker基础镜像导入docker服务

[local ~]# cat system.tar | docker import - kylin-diy:v10.1.0.0

检查docker基础镜像情况

[local ~]# docker images
REPOSITORY   TAG         IMAGE ID       CREATED          SIZE
kylin-diy    v10.1.0.0   6712a70e2066   15 minutes ago   783MB

运行docker基础镜像

[local ~]#  docker ps
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES

[local ~]#  docker run -itd --privileged --name kylinv10 kylin-diy:v10.1.0.0 /usr/sbin/init
