I'm trying to create .yaml and .jinja files for a full cloud deployment, but have become stuck with deploying Cloud spanner, I am aware that it is a PaaS Application, so how would such application be implemented if it can at all?
I am relatively new to this area and am currently experimenting with cloud technology.
Cloud Spanner does not require a configuration file for deployment. You can create a new Cloud Spanner instance using the Google Cloud Console UI and point your application to it. Follow the instructions in: https://cloud.google.com/spanner/docs/create-manage-instances
