Rackspace CloudFiles can be configured using a CNAME DNS record. For more information on this Rackspace provide some documentation here.
- Login to your Cloudflare account.
- From the dropdown on the top right, select your domain.
- Select the DNS settings tab.
- Select CNAME record and add your DNS values.
You may notice that you cannot "Orange Cloud" this record. Because rackcdn is not compatible with Cloudflare, we have removed this functionality.
