如何编写 Dockerfile 命令来安装下面的 Alpine docker 镜像文件:
The equivalent of apt or apt-get in Alpine is apk
apt
apt-get
apk
A typical Dockerfile will contain, for example:
RUN apk add --no-cache wget
--no-cache is the equivalent to: apk add wget && rm -rf /var/cache/apk/*
--no-cache
apk add wget && rm -rf /var/cache/apk/*
or, before the --no-cache option was available:
RUN apk update && apk add wget
Alpine rm -rf /var/cache/apk/* has the Debian equivalent rm -rf /var/lib/apt/lists/*.
rm -rf /var/cache/apk/*
rm -rf /var/lib/apt/lists/*
See the Alpine comparison with other distros for more details.
