工作需要，客户想在K8s集群中搭建Greenplum集群，要求操作系统是麒麟V10。虽然数据库不建议安装在k8s中，但客户就是上帝，那就试试吧。本文讲解第一步：制作一个基于麒麟V10的Docker镜像。
- 银行麒麟官网下载镜像。此次下载服务器版。
- 使用麒麟V10的ISO镜像，最小化安装虚拟机。此步很简单，省略。
- 构建镜像文件 3.1 在虚拟机中创建准备目录
mkdir /kylin
mkdir -p /kylin/usr /kylin/dev
3.2 复制相关文件,并创建软链接
cp -a /usr/lib /usr/lib64 /usr/bin /usr/share /kylin/usr/
ln -s /kylin/usr/lib /kylin/lib
ln -s /kylin/usr/lib64 /kylin/lib64
ln -s /kylin/usr/bin /kylin/bin
完成后，显示如下：
[root@localhost kylin]# ll
总用量 0
lrwxrwxrwx 1 root root 8 9月 20 10:14 bin -> /usr/bin
drwxrwxr-x 2 gpadmin gpadmin 6 9月 20 10:07 dev
lrwxrwxrwx 1 root root 7 9月 20 10:13 lib -> usr/lib
lrwxrwxrwx 1 root root 9 9月 20 10:14 lib64 -> usr/lib64
drwxrwxr-x 6 gpadmin gpadmin 54 9月 20 10:09 usr
3.3 复制配置以及root目录
cp -a /etc /root ./
# 完成后目录如下：
[root@localhost kylin]# ll
总用量 12
lrwxrwxrwx 1 root root 8 9月 20 10:14 bin -> /usr/bin
drwxrwxr-x 2 gpadmin gpadmin 6 9月 20 10:07 dev
drwxr-xr-x 142 root root 8192 9月 20 10:15 etc
lrwxrwxrwx 1 root root 7 9月 20 10:13 lib -> usr/lib
lrwxrwxrwx 1 root root 9 9月 20 10:14 lib64 -> usr/lib64
dr-xr-x--- 4 root root 169 9月 20 10:04 root
drwxrwxr-x 6 gpadmin gpadmin 54 9月 20 10:09 usr
3.4 裁剪脚本
rm -rf etc/profile.d/flatpak.sh etc/profile.d/gawk.csh etc/profile.d/gawk.sh etc/profile.d/lang.csh etc/profile.d/lang.sh etc/profile.d/system-info.sh
3.5 测试镜像目录
[root@localhost kylin]# chroot .
[root@localhost /]#
如无问题，可打包：
tar -C kylin-docker-fs/ -z -c . -f kylin-docker.tar.gz
- 构建docker镜像 首先把kylin-docker.tar.gz文件移动到自定目录，用于构建镜像。然后在该目录下，编辑DockerFile，写入内容如下：
FROM scratch
ADD kylin-docker.tar.gz /
LABEL \
org.label-schema.schema-version="1.0" \
org.label-schema.name="Kylin Base Image" \
org.label-schema.vendor="Kylin" \
org.label-schema.license="GPLv2" \
org.label-schema.build-date="20230920" \
org.opencontainers.image.title="Kylin Base Image" \
org.opencontainers.image.vendor="Kylin" \
org.opencontainers.image.licenses="GPL-2.0-only" \
org.opencontainers.image.created="2023-09-20 10:36:00+00:00"
CMD ["/bin/bash"]
保存后，构建镜像测试
