I have an OpenShift application with custom domain alias, but it's not working sometimes. I followed their instructions for setting an alias, I added a CNAME record at the root of my domain pointing to my .rhcloud.com domain. I use Cloudflare to host my DNS.
It works fine but sometimes it returns error 404. I configured this domain last week so I don't think it's DNS propagation.
Here's the screenshot http://i.stack.imgur.com/paUge.png (sorry I don't have enough rep to post image).
Looks like you are using an A record to point your domain to your openshift gear, we suggest that you use a CNAME to point to your gear in case your gear is migrated to another node
cdaley-redhat:~ cdaley$ host www.codingpoop.com
www.codingpoop.com is an alias for codingpoop.com.
codingpoop.com has address 54.224.51.84
codingpoop.com mail is handled by 0 codingpoop.com.
You should do the cname for www.codingpoop.com, and then forward the naked domain of codingpoop.com to the cname of www
