How do I write Dockerfile commands to install the following in alpine docker image:
The equivalent of apt
or apt-get
in Alpine is 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/*
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/*
.
See the Alpine comparison with other distros for more details.
