app.yaml to send params to Dockerfile

[Seungryul Choi]

Hi,

I am deploying a binary on Google cloud flexible app engine for two different services. So I have {app-service1.yaml, Dockerfile-service1} and {app-service2.yaml, Dockerfile-service2}. And use "gcloud app deploy" command to deploy them.

Is it possible to send a param from app-service[1|2].yaml to a single Dockerfile, so that I can maintain only one Dockerfile?

I tried two things but they didn't work with "gcloud deploy" command:

• "entrypoint:" in app.yaml -- It does not override what is set in CMD in Dockerfile.
  
• "env_variables:" in app.yaml -- Dockerfile's ENV or ARG do not see any variables defined in env_variables:.

I was hoping that gcloud command can send environment variables to a container, but any method of sending parameters to a container would be very useful to me.

Thanks.

This functionality doesn't exist, but you could file a feature request on the google-cloud-sdk issue tracker.
