Knative services are automatically assigned a default domain name based on your cluster configuration. For example,
<service_name>-<namespace>.example.com. You can customize the domain for your Knative service by mapping a custom domain name that you own to a Knative service.
You can do this by creating a
DomainMapping resource for the service. You can also create multiple
DomainMapping resources to map multiple domains and subdomains to a single service.
