BUILD-DOCKER-IMAGE.sh

#!/bin/bash
# Generates a docker image with the relevant settings for the DOCKER_PROJECT.
# Context-sensitive behaviour: If the <user> parameter "gitlab-ci" is used, 
# the script builds the image without trying to download it.
#
# Usage: ./BUILD-DOCKER-IMAGE.bash <optional: user>
#
# @param <user> [optional parameter] for docker container naming during spin-up and to set different behavior.
#                  Default value: $USER - the image is pulled from repo, or built as fallback.
#                  If <user> is "gitlab-ci" the image is directly build from scratch - as if done in gitlab-ci.
