This file must be a list of <name>=<value> pairs. A parameter reference may appear in any text field inside the template items.

The parameters that we must override are the following

$ cat paramfile
  APPLICATION_NAME=app-Name
  APPLICATION_GROUP_NAME=group-Name
  GIT_URI=Git uri
  GIT_REF=master
  CONTEXT_DIR=/context

The following parameters are optional

$ cat paramfile
  APPLICATION_HOSTNAME=Custom hostname for service routes. Leave blank for default hostname, e.g.: <application-name>.<project>.<default-domain-suffix>,
  # Only for angular
  REST_ENDPOINT_URL=The URL of the backend's REST API endpoint. This can be declared after,
  REST_ENDPOINT_PATTERN=The pattern URL of the backend's REST API endpoint that must be modify by the REST_ENDPOINT_URL variable,
