# This Cloud Build job prepares and applies Google Cloud Deploy configurations.
# It merges the internal repository and populates stableDeploymentAlertPolicyChecks
# in delivery-pipeline.yaml based on environment-specific configuration files.
#
# To manually trigger a build on GCB, run:
# gcloud builds submit --config release/cloudbuild-clouddeploy.yaml --substitutions \
#   _INTERNAL_REPO_URL=[URL],PROJECT_ID=[PROJECT_ID] ..

steps:
# Check the out internal repo.
