We need to create the necessary objects that require the cluster-admin role. Let's see how to do this:

1. To create objects that require the cluster-admin role, run the following command:

$ linkerd install config | kubectl apply -f -

These objects include ClusterRole, ClusterRoleBinding, CustomResourceDefinition, MutatingWebhookConfiguration, Secret, ServiceAccount, and so on.

2. To validate the objects, run the following command:

$ linkerd check config

Now that the necessary objects have been created, we can install the control plane.
