Creating a custom domain mapping by using the Knative CLI

Prerequisites

The OpenShift Serverless Operator and Knative Serving are installed on your cluster.
You have created a Knative service or route, and control a custom domain that you want to map to that CR.

Your custom domain must point to the dns of the OpenShift Container Platform cluster.
You have installed the Knative (kn) CLI.
You have created a project or have access to a project with the appropriate roles and permissions to create applications and other workloads in OpenShift Container Platform.

Procedure

Map a domain to a CR in the current namespace:
```
$ kn domain create <domain_mapping_name> --ref <target_name>
```
Example command
```
$ kn domain create example.com --ref showcase
```
The --ref flag specifies an Addressable target CR for domain mapping.

If a prefix is not provided when using the --ref flag, it is assumed that the target is a Knative service in the current namespace.

Map a domain to a Knative service in a specified namespace:

$ kn domain create <domain_mapping_name> --ref <ksvc:service_name:service_namespace>

Example command

$ kn domain create example.com --ref ksvc:showcase:example-namespace

Map a domain to a Knative route:

$ kn domain create <domain_mapping_name> --ref <kroute:route_name>

Example command

$ kn domain create example.com --ref kroute:example-route

Managing custom domain mappings by using the Knative CLI

After you have created a DomainMapping custom resource (CR), you can list existing CRs, view information about an existing CR, update CRs, or delete CRs by using the Knative (kn) CLI.

Prerequisites

The OpenShift Serverless Operator and Knative Serving are installed on your cluster.
You have created at least one DomainMapping CR.
You have installed the Knative (kn) CLI tool.
You have created a project or have access to a project with the appropriate roles and permissions to create applications and other workloads in OpenShift Container Platform.

Procedure

List existing DomainMapping CRs:

$ kn domain list -n <domain_mapping_namespace>

View details of an existing DomainMapping CR:

$ kn domain describe <domain_mapping_name>

Update a DomainMapping CR to point to a new target:
```
$ kn domain update --ref <target>
```

Delete a DomainMapping CR:

$ kn domain delete <domain_mapping_name>
