Reserving an IPv4 Address
Your OpenShift will require DNS records that are configured in advance. We do not provide DNS services directly, so you'll need to able to do that with another service.
Within our portal, you can add IP addresses to your account. Create the following DNS records that point to your IP address.
- app.[Your Cluster Name].yourdomain.com -> Your Slicie IP
- *.apps.[Your Cluster Name].yourdomain.com -> Your Slicie IP
- app-int.[Your Cluster Name].yourdomain.com -> Your Slicie IP
