Google App Engine and domain name

Question

Here is the situation:

I own a Google Apps for Business account.

I have two domain names registered :

• mycompany.com which is the principal domain
• myapp.com which is another domain

Note: both domains are validated and active.

I'm working on a Google App Engine web application and I want it to be accessible via myapp.com or www.myapp.com.

What I've done so far :

• I've added the GAE web application as a service in my Google Apps account.
• I've tried to change the url but myapp.com does'nt appear in the dropbox.

This thing starts to drive me mad...

Answer 1

It doesn't seem possible ATM to bind an App Engine application on a Google Apps Secondary Domain (sounds like a bug).

But it works fine on Google Apps Domain Alias.

• Go to https://www.google.com/a/cpanel/yourprimarydomain.com/DomainSettingsDomains
• Click Add a domain alias or a domain
• Select Add a domain alias of yourprimarydomain.com
• Follow instructions to verify your domain
• Go to your App Engine application dashboard
• Go to Application Settings
• Click Add Domain
• Type the domain name of your primary Google Apps domain (not the alias)
• Click Add new URL
• Select your domain alias from the dropdown list
• Click Add
• You will be asked to add a CNAME to ghs.google.com in your DNS configuration

That should work.
