10.3.2. Create a primary user-defined network by using the CLI

Procedure

1. Create a Namespace object as a YAML file similar to the following example:

   apiVersion: v1
   kind: Namespace
   metadata:
     name: my-namespace
     labels:
       k8s.ovn.org/primary-user-defined-network: ""
   # ...

   The k8s.ovn.org/primary-user-defined-network label is required for the namespace to be associated with a UDN. If the namespace is to be used with an existing cluster UDN, you must also add the appropriate labels that are defined in the spec.namespaceSelector field of the ClusterUserDefinedNetwork custom resource.

2. Apply the Namespace manifest by running the following command:

   $ oc apply -f <filename>.yaml
