Unable to create custom DNS + CNAME

[kuldeepaggarwal]

I am trying to create a custom DNS + CNAMe via platform-api gem but still not able to set custom CNAME, e.g.

heroku = PlatformAPI.connect_oauth('API-key')
heroku.domain.create( 'brandnew-advertiser-fe-staging', {"hostname" => 'mediacom.brandnew.in', "kind" => "custom", "cname" => "brandnew-advertiser-fe-staging.herokuapp.com"})

# => {"app"=>{"id"=>"<APP_ID>", "name"=>"brandnew-advertiser-fe-staging"}, "cname"=>"mediacom.brandnew.in.herokudns.com", "created_at"=>"2017-01-13T10:02:40Z", "hostname"=>"mediacom.brandnew.in", "id"=>"<ID>", "kind"=>"custom", "status"=>"pending", "updated_at"=>"2017-01-13T10:02:40Z"}

you can see that cname is not same.

@kuldeepaggarwal cname is a readonly attribute that is set internally by heroku. Sorry that this is not obvious from the platform docs. What you should do is omit cname from the post body when you are generating a custom domain and let heroku generate a cname for you.

When you created your custom domain heroku set up mediacom.brandnew.in.herokudns.com for you to point your DNS CNAME record at. Once DNS is configured properly, this will allow mediacom.brandnew.in to be served by heroku infrastructure.

This appear to have a clear answer now, closing. Please let us know if you have further questions.

Hey Ransombriggs & geemus , I am also stuck on a similar problem where my python app hosted on heroku has a default heroku dns address and I am saving the same entry in NS and keeping CNAME as empty. I am unable to make requests to my domain.

@ayushgangrade11 sorry to hear you are still having issues. If you could file a support ticket on heroku, they should better be able to help you with that specific setup.
