After successfully deploying a test app using the steps outlined here: http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create_deploy_Python_flask.html
I tried
Add the following to .ebextensions/:
option_settings:
"aws:elasticbeanstalk:container:python":
WSGIPath: myApp/handlers/views.py
Update:
If you don't have .ebextensions directory, please create one for the project. You can find more information of what can be done regarding the container configuration in Customizing and Configuring AWS Elastic Beanstalk Environments guide.
