Alpine
Alpine
Alpine 是一个仅 5 MB 的最小 Linux 发行版,使用 apk 作为包管理工具。
遇到的问题
切换镜像源
如果不想备份原文件,可以直接 sed -i
。
原文件内容:
http://dl-cdn.alpinelinux.org/alpine/v3.11/main
http://dl-cdn.alpinelinux.org/alpine/v3.11/community
修改后的文件内容:
设置时区
apk add --no-cache tzdata \
&& ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
&& echo "Asia/Shanghai" > /etc/timezon
找不到包
包的搜索地址:
<https://pkgs.alpinelinux.org/packages >
只需要加入对应的 branch 和 repository 到 /etc/apk/repositories
中。
避免安装缓存
apk 提供了两个参数非常实用:--no-cache
、--virtual
使用 --no-cache
不会保存缓存的安装包,无需手动清理缓存。
使用 --virtual
不会添加软件包到全局软件包中,这种变化可以很容易回滚。
注意:同一个 --virtual
参数会覆盖之前的所有安装包。
比如同时执行了:
apk add --no-cache --virtual .ruby-builddeps \
gcc \
dpkg
apk add --no-cache --virtual .ruby-builddeps \
gcc
实际上只安装了 gcc 到 .ruby-builddeps
