# TODO(Dobroslaw): move this script to monasca-common/docker folder
# and leave here small script to download it and execute using env variables
# to minimize code duplication.
set -x # Print each script step.
set -eo pipefail # Exit the script if any statement returns error.
# This script is used for building Docker image with proper labels
# and proper version of monasca-common.
#
# Example usage:
# $ ./build_image.sh <repository_version> <upper_constains_branch> <common_version>
#
# Everything after `./build_image.sh` is optional and by default configured
# to get versions from `Dockerfile`.
#
# To build from master branch (default):
# $ ./build_image.sh
# To build specific version run this script in the following way:
# $ ./build_image.sh stable/queens
# Building from specific commit:
# $ ./build_image.sh cb7f226
# When building from a tag monasca-common will be used in version available
# in upper constraint file:
# $ ./build_image.sh 2.5.0
# To build image from Gerrit patch sets that is targeting branch stable/queens:
# $ ./build_image.sh refs/changes/51/558751/1 stable/queens
#
# If you want to build image with custom monasca-common version you need
# to provide it as in the following example:
# $ ./build_image.sh master master refs/changes/19/595719/3
# Go to folder with Docker files.
