Heroku Subdomain to External Site

Question

I am hosting my rails application on heroku.com

My Goal

I want my site www.example.com to have a subdomain www.blog.example.com that will load my blog at ghost.io

My ghost.io has a different url www.example.ghost.io

I don't want the user redirected to the www.example.ghost.io, I want the ghost blog to be loaded under the blog subdomain.

Is it possible to do this? If so, how could I achieve this? Thanks in advance!

Answer 1

This would be done through the DNS settings of your domain name provider, such as GoDaddy, and not through rails. You would create a subdomain entry www.blog.example.com that points to the IP address of www.example.ghost.io. Here is a guide for GoDaddy; all DNS providers should have a similar guide: https://www.godaddy.com/help/add-a-subdomain-that-points-to-an-ip-address-4080.
