An OpenShift Online route exposes a service at a host name, such as www.example.com, so that external clients can reach it by name.
DNS resolution for a host name is handled separately from routing. Your administrator may have configured a DNS wildcard entry that will resolve to the OpenShift Online node that is running the OpenShift Online router. If you are using a different host name you may need to modify its DNS records independently to resolve to the node that is running the router.
Each route consists of a name (limited to 63 characters), a service selector, and an optional security configuration.
Wildcard routes are disabled in OpenShift Online.
