配置Alpine源镜像
通过uname -a、cat /etc/issue，确认系统信息；
960ddd5f80cc:/# uname -a
Linux 960ddd5f80cc 4.4.302+ #64570 SMP Tue Jun 13 21:40:17 CST 2023 x86_64 Linux
960ddd5f80cc:/# cat /etc/issue
Welcome to Alpine Linux 3.17
Kernel \r on an \m (\l)
备份配置repositories文件；
960ddd5f80cc:/# cp -a /etc/apk/repositories /etc/apk/repositories.bak
960ddd5f80cc:/# cd /etc/apk/
960ddd5f80cc:/etc/apk# ls
arch keys protected_paths.d repositories repositories.bak world
修改repositories文件，
将https://dl-cdn.alpinelinux.org/替换成https://mirrors.huaweicloud.com/，可以参考如下命令sed -i "s@https://dl-cdn.alpinelinux.org/@https://mirrors.huaweicloud.com/@g" /etc/apk/repositories或者直接注释原来的地址，再添加新镜像域名的地址；
960ddd5f80cc:/etc/apk# vi repositories
960ddd5f80cc:/etc/apk# cat repositories
# https://dl-cdn.alpinelinux.org/alpine/v3.17/main
# https://dl-cdn.alpinelinux.org/alpine/v3.17/community
https://repo.huaweicloud.com/alpine/v3.17/main
https://repo.huaweicloud.com/alpine/v3.17/community
执行apk update更新索引，执行apk search xxx查询软件包，执行apk install xxx安装软件包`
