How do I use a naked/apex domain with App Engine?

Question

How do I serve my App Engine app from a naked domain http://example.com? I don't want to redirect from http://example.com to http://www.example.com. I want serve from http://example.com.

Are there any reverse proxy services that would allow me to do this? I see CloudFlare has just released CNAME flattening specifically to support naked domains. However I have tried to setup a CNAME record for example.com to myapp.appspot.com but it appears not to work. Maybe the new Google Cloud DNS would work?

What have others done to make this work?

Answer 1

I just discovered today (as of 2014-04-11) a new custom domain settings page is available from Google Developers Console:

1. Go to https://console.developers.google.com/project
2. Click on your project
3. On the left click "App Engine"
4. Click "Settings"

There you can have the option to add naked domain directly.
