Setting up Serverless VPC Access on App Engine with variable project name

Question

I have an App Engine app that's attempting to connect to Redis Memcache via a serverless VPC connector. In my app.yaml for my service, I have setup the VPC Access connector block as

vpc_access_connector:
  name: 'projects/<project_name>/locations/<region>/connectors/<connector>'

with the appropriate variables filled in. This works fine for the particular project I'm currently deploying to which is our testing project, but soon I'll need to deploy this to a different project with a different region and a different connector. Is there a way to setup this connection at runtime (when I have access python side to environment variables) rather than in the app.yaml file, or a way to pass environment variables to the name value in the yaml here?

Answer 1

I verified this inquiry in the Github for the python client library but I did not found any way to achieve this. It seems that the only available option is adding the variable in the app.yaml

On the other hand, I would like to let you know that that I raised this Public Issue Tracker requesting this since App engine can use the Admin API to update certain elements from the app.yaml file like automaticScaling.min_idle_instances , manualScaling.instances and automaticScaling.max_total_instances, so I consider a good idea have a similar method to update the vpc_access_connector.
