How to stop or disable Google App Engine production server?

Question

I have uploaded google app java project to production google app engine (from this tutorial), but I can\'t found any information how to stop or disable the production app engine

Answer 1

For me none of the other solutions were applicable as I was testing AppEngine on a project that already used Firestore, and disabling the app would disable it as well which was not an option.
I contacted Google and this is the solution they gave me:

You can overwrite the default version of your app by redeploying the app with an empty application and create an app.yaml that uses only static files:

module: default
runtime: python27
api_version: '1.0'
threadsafe: true
handlers:
  - url: /
    static_files: index.html
    upload: index.html
manual_scaling:
  instances: 1

a dummy index.html like:

and deploy it using: gcloud app deploy app.yaml

Then you can stop your app using gcloud app versions stop VERSION_ID
