https://cloud.google.com/deployment-manager/docs/configuration/templates/define-template-properties
--properties is only supported for Jinja templates:
gcloud deployment-manager deployments create a-single-vm --template vm_template.jinja \
--properties zone:us-central1-a
How do I pass properties to Python templates the same way with --config?
Edit
More info about my use case. I have a top level yaml config that pulls in multiple templates and sets properties. I can just create separate top level configs for dev and prod deployments with diff values for those environments but it would be nice to set these via command line.
Also I may need to dynamically change some of these params at deploy time in my deployment automation- for example when users click a button to deploy they are given the option to set some params to change. Is there any native support for transforming configs? I don't want to have to resort to wrapping my configs with a makefile.
