14.3. Custom domains for Knative services 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.

  注記

  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
