$ dotcloud alias add ramen.www www.example.com
dotCloud, thank you for supporting custom domain for free users. I could set up my domain.
And I noted one more thing.
If you want to use your domain at dotCloud, yeah, dotCloud makes it easy for adding your domain. But also you need to add CNAME to your DNS.
When you finished to run the command, you can see like this.
$ dotcloud alias add ramen.www www.example.com Ok. Now please add the following DNS record: www.example.com. IN CNAME gateway.dotcloud.com.
And you can check it by yourself.
$ dotcloud info mologorg www: config: path: / instances: 1 type: static url: http://www.example.com/
I hope that you could see your contents by your domain.
