I have a old site in PHP that is hosted on media temple. but i want to add a admin area in rails hosted on HEROKU.
i am trying to set follower the sub-domain name admin.mysite.com to heroku.
on my media temple account i go to Edit Zone File : mysite.com I add a new row
Name = admin Type = cname data = mysite.herokuapp.com
but when i go to mysite.herokuapp.com it works fine but when i go to admin.mysite.com i get Heroku | No such app
What can i do?
You need to add a custom domain to your Heroku app. See this Dev Center guide, Custom Domains.
Essentially:
$ heroku domains:add admin.mysite.com --app my_app
