# This script deploys gaby to Cloud Run.
# It takes a single argument, the Firestore database name, which
# is also the suffix of the Cloud Run service name.
#
# Example:
#
#    deploy-cloud-run.sh devel
#
# This command builds a docker container for gaby that refers the Firestore "devel"
# database, and deploys it as the Cloud Run service "gaby-devel".
#
# The script requires the OSCAR_PROJECT environment variable to be set to the project
# ID of the GCP project hosting Oscar.
#
# The script passes false for both the -enablesync and -enablechanges flags to gaby.
# Edit the script to pass true for one or both of them.
#
# You should avoid using this script to deploy to prod unless you know what you are doing.
# And you should avoid deploying anywhere from a workspace with uncommitted files;
# when debugging, it may be impossible to retrieve the exact source that produced the container.
#
# This script requires the following GCP permissions, and possibly others:
#     Cloud Run Developer
