11.9. Custom Domains and SSL Certificates

Custom domain aliases are designated so that applications can use custom DNS entries rather than the domain generated by the system. Note that a CNAME record with your DNS provider is required for custom aliases to work correctly.
Custom SSL certificates with domain aliases are available for added security to users with upgraded OpenShift Online accounts.
