You can use
drycc domains to add or remove custom domains to the application:
$ drycc domains:add hello.bacongobbler.com Adding hello.bacongobbler.com to finest-woodshed... done
Once that's done, you can go into a DNS registrar and set up a CNAME from the new appname to the old one:
$ dig hello.dryccapp.com [...] ;; ANSWER SECTION: hello.bacongobbler.com. 1759 IN CNAME finest-woodshed.dryccapp.com. finest-woodshed.dryccapp.com. 270 IN A 172.17.8.100
Setting a CNAME for a root domain can cause issues. Setting an @ record to be a CNAME causes all traffic to go to the other domain, including mail and the SOA ("start-of-authority") records. It is highly recommended that you bind a subdomain to an application, however you can work around this by pointing the @ record to the address of the load balancer (if any).
To add or remove the application from the routing mesh, use
$ drycc routing:disable Disabling routing for finest-woodshed... done
$ drycc routing:enable Enabling routing for finest-woodshed... done
