= Creating a custom domain mapping
|
|
|
|
You can customize the domain for your Knative service by mapping a custom domain name that you own to a Knative service. To map a custom domain name to a custom resource (CR), you must create a `DomainMapping` CR that maps to an Addressable target CR, such as a Knative service or a Knative route.
|
|
|
|
.Prerequisites
|
|
|
|
* The {ServerlessOperatorName} and Knative Serving are installed on your cluster.
|
|
* Install the OpenShift CLI (`oc`).
|
|
* You have created a project or have access to a project with the appropriate roles and permissions to create applications and other workloads in {product-title}.
|
|
* You have created a Knative service and control a custom domain that you want to map to that service.
|
|

|
|
[NOTE]
|
|
====
|
|
Your custom domain must point to the IP address of the {product-title} cluster.

.Procedure
|
|
|
|
. Create a YAML file containing the `DomainMapping` CR in the same namespace as the target CR you want to map to:
|
|
+
|
|
[source,yaml]
|
|
----
|
|
apiVersion: serving.knative.dev/v1alpha1
|
|
kind: DomainMapping
|
|
metadata:
|
|
name: <domain_name> <1>
|
|
namespace: <namespace> <2>
|
|
spec:
|
|
ref:
|
|
name: <target_name> <3>
|
|
kind: <target_type> <4>
|
|
apiVersion: serving.knative.dev/v1
|
|
----
|
|
<1> The custom domain name that you want to map to the target CR.
|
|
<2> The namespace of both the `DomainMapping` CR and the target CR.
|
|
<3> The name of the target CR to map to the custom domain.
|
|
<4> The type of CR being mapped to the custom domain.
