== Using the Node Feature Discovery Operator

The Node Feature Discovery (NFD) Operator orchestrates all resources needed to run the Node-Feature-Discovery daemon set by watching for a `NodeFeatureDiscovery` custom resource (CR). Based on the `NodeFeatureDiscovery` CR, the Operator creates the operand (NFD) components in the selected namespace. You can edit the CR to use another namespace, image, image pull policy, and `nfd-worker-conf` config map, among other options.

As a cluster administrator, you can create a `NodeFeatureDiscovery` CR by using the {oc-first} or the web console.

= Creating a NodeFeatureDiscovery CR by using the CLI in a disconnected environment

As a cluster administrator, you can create a `NodeFeatureDiscovery` CR instance by using the {oc-first}.

.Prerequisites

* You have access to an {product-title} cluster
* You installed the {oc-first}.
* You logged in as a user with `cluster-admin` privileges.
* You installed the the NFD Operator.
* You have access to a mirror registry with the required images.
* You installed the `skopeo` CLI tool.
.Procedure

. Determine the digest of the registry image:

.. Run the following command:
+
[source,terminal]
----
$ skopeo inspect docker://registry.redhat.io/openshift4/ose-node-feature-discovery:<openshift_version>
----
+
.Example command
[source,terminal]
----
$ skopeo inspect docker://registry.redhat.io/openshift4/ose-node-feature-discovery:v4.12
----

.. Inspect the output to identify the image digest:
+
.Example output
[source,terminal]
----
{
...
"Digest": "sha256:1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef",
...
}
----

. Use the `skopeo` CLI tool to copy the image from `registry.redhat.io` to your mirror registry, by running the following command:
+
[source,terminal]
----
skopeo copy docker://registry.redhat.io/openshift4/ose-node-feature-discovery@<image_digest> docker://<mirror_registry>/openshift4/ose-node-feature-discovery@<image_digest>
----
