##########################################################################################################################

 This script gets triggered by the automated CI/CD jobs of AppSRE. It builds and pushes '${PROJECT_NAME}' image to the
 'rhoas' organization in 'quay.io' registry(defaults). Quay-organization, Image name and tags are configurable.

 In order to work, it needs the following variables defined in the CI/CD configuration of the project:

 RHOAS_QUAY_USER - The name of the robot account
                   used to push images to 'quay.io'

 RHOAS_QUAY_TOKEN - The token of the robot account
                    used to push images to 'quay.io'

 The machines that run this script need to have access to internet, so that the built images can be pushed.


Usage: $0 [options]
Example: $0 --org rhoas --name srs-service-registry --tag 2.0.0.Final

options include:

-o, --org         The organization the container image will be part of. If not set defaults to 'rhoas'
-t, --tag         The tag of the container image. If not set defaults to 'latest'
-h, --help        This help message
