# 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_DOCKER_REPO
|
|
# A DockerHub repository. By default the CD_REF_SLUG is also used as the docker repo.
|
|
#
|
|
# 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.
