Managing two instances of the same GAE application

Question

I have an GAE app, and I deploy it on 2 different domains, and they use separate datastores.

However, right now it is done by having two identical folders with different app.yaml configurations.

If I make changes I need to copy all files again. Is there an elegant solution for that, like having two app.yaml files in the same folder?

Answer 1

Use a single application, with namespaces to separate data between domains.

Answer 2

Appcfg.py has a --application command line option that is supposed to override the value in your app.yaml. Using that you could deploy the same directory to two different apps.
