For each custom subdomain use domains:add
in the Terminal.
heroku domains:add www.example.com
Go to the domain's DNS manager and configure it with a CNAME record pointing the subdomain to your herokuapp.com hostname.
Record | Name | Target |
---|---|---|
CNAME | www | example.herokuapp.com |
To check that this worked correctly run host www.example.com
This will work to have www.example.com forward to www.example.herokuapp.com, but it won't work if a user types example.com into the browser.
To get this to work, go to the GoDaddy domain information and set forwarding to www.example.com.
This saved me a bunch of time futzing with GoDaddy. Thx man!
