# Builds the container from source using Cloud Build and deploys it to
# Cloud Run. Cloud Run sets the PORT env var automatically and auto-scales
# to zero when idle.
#
# Usage:
# ./deploy_cloudrun.sh # Interactive setup
# ./deploy_cloudrun.sh --project=my-project # Explicit project
# ./deploy_cloudrun.sh --region=europe-west1 # Non-default region
