# For this script to work properly it is required to define some environment variables
# in the CI/CD Env variable declaration, while others should be passed as parameters.
#
#------------------------------------------------------------------------------
# Defined as part of the CD/CI Env Variables:
#
# CD_DOCKER_USERNAME
# A DockerHub username to be used for uploading the build.
#
# CD_DOCKER_PASSWORD
# A DockerHub password to be used for uploading the build.
#
# CD_BUILD_ALL
# As the build is supposed to be done only for master (for a nightly deployments) and for releases
# (like 'release-2.0.5' for production deployments), it is additionally required to include this
# variable in order to build any other brnach, as it may be required for testing or reviewing work
# as part of the development process.
