在AWS Elasticbeanstalk上的Rails 3中设置子域

Question

My rails app has the following subdomains: my, admins, locations

I have set up my routes file as follows:

routes.rb

match '/' => 'admins#index', :constraints => { :subdomain => "admins" }
match '/' => ‘users#index', :constraints => { :subdomain => "my" }
match '/' => ‘locations#index', :constraints => { :subdomain => “locations” }

Locally, this works fine…If I point to admins.lvh.me, or my.lvh.me, it points to the right page.

My issue is when I deploy it to AWS ElasticBeanstalk. Elasticbeanstalk makes my app accessible at aws_assigned_name.elasticbeanstalk.com. So I added a CNAME to my DNS as follows:

my.mydomain.com CNAME aws_assigned_name.elasticbeanstalk.com

Can I do this multiple times, one for each subdomain? So my DNS would look like:

my.mydomain.com CNAME aws_eb_assigned_name.elasticbeanstalk.com
admins.mydomain.com CNAME aws_eb_assigned_name.elasticbeanstalk.com
locations.mydomain.com CNAME aws_eb_assigned_name.elasticbeanstalk.com

Or what is the generally accepted method to handle this?

Answer 1

You can add a wildcard CNAME. This will redirect all your subdomains.

*.mydomain.com CNAME aws_eb_assigned_name.elasticbeanstalk.com
