# Slackware Build Node contains compiler toolchains and utils
# required to build software.
# We build it on top of a minimal Slackware i.e. with minimal dependencies.

# Note that ARG is the only keyword that's allowed before FROM:
ARG SL_ARCH="amd64"
ARG SL_ARCHSUFF="64"
ARG SL_VERSION="14.2"
ARG SL_IMAGE="liveslak/slackware:base_${SL_ARCH}_${SL_VERSION}"

FROM "${SL_IMAGE}"

# ARG defined before FROM cannot be used after FROM:
ARG SL_UID="1000"
ARG SL_GID="users"
ARG SL_USER="live"

# Install compiler toolchain and supporting tools.
# Note that not all of these will be available on Slackware < 15.0,
# I made the package list so that it gives you a functional environment
# both on Slackware 14.2 and 15.0:
