Step-by-step shell snippets how to build gateleen
=================================================


## Alpine

  && PKGS_TO_ADD="curl maven nodejs npm redis openjdk11-jre-headless" \
  && SUDO="${HOME:?}/.local/bin/mysudo" \
  && PKGINIT=true \
  && PKGADD="$SUDO apk add" \
  && PKGCLEAN=true \
  && mkdir -p "${HOME:?}/.local/bin" \
  && printf '%s\n' '#!/bin/sh' 'printf "Sudo "' 'su root -c "$(echo "$@")"' > "${HOME:?}/.local/bin/mysudo" \
  && chmod u+x "${HOME:?}/.local/bin/mysudo" \


## Generic

  && GATELEEN_GIT_TAG="v1.3.28" \
  && WORKDIR="/${HOME:?}/work" \
  && CACHE_DIR="/var/tmp" \


## Setup Dependencies & get sources

  && ${PKGINIT:?} && ${PKGADD:?} $PKGS_TO_ADD \
  \
  && curl -sSL https://github.com/swisspush/gateleen/archive/refs/tags/"${GATELEEN_GIT_TAG:?}".tar.gz > "${CACHE_DIR:?}/gateleen-${GATELEEN_GIT_TAG:?}.tgz" \


## Corporation specific setup

- Configure proxy if needed.
- Configure "/home/user/.npmrc" if needed.
- Configure "/home/user/.m2/settings.xml" if needed.
