Install NVIDIA Network Operator (Optional)

Added in version 2.0.

Next, we will install the NVIDIA Network Operator. This only applicable if you worker nodes have NVIDIA Networking. The Network Operator’s goal is to install the host networking components required to enable RDMA and GPUDirect in a Kubernetes cluster. It does so by configuring a high-speed data path for IO intensive workloads on a secondary network in each cluster node.

1. Select Operators > Operator Hub, and search for the NVIDIA Network Operator.

2. Select the NVIDIA Network Operator, and click Install in the first screen and in the subsequent one.

   Note

   For additional information, see the Red Hat OpenShift Container Platform Documentation.

Install NVIDIA Network Operatior via CLI

The NVIDIA Network Operator can also be installed using CLI. The steps are provided for informational purposes.

1. Create a namespace for the Network Operator.

   Create the following Namespace custom resource (CR) that defines the network-operator namespace, and then save the YAML in the network-operator-namespace.yaml file:

   apiVersion: v1
   kind: Namespace
   metadata:
   name: network-operator
   

   Create the namespace by running the following command:

   $ oc create -f network-operator-namespace.yaml
   

2. Install the Network Operator in the namespace you created in the previous step by creating the below objects.

   Run the following command to get the channel value required for the next step:

   $ oc get packagemanifest network-operator -n openshift-marketplace -o jsonpath='{.status.defaultChannel}'
   

3. Example Output:

   stable
   

4. Create the following Subscription CR, and save the YAML in the network-operator-sub.yaml file:

   apiVersion: operators.coreos.com/v1alpha1
   kind: Subscription
   metadata:
       name: network-operator
       namespace: network-operator
   spec:
       channel: "stable"
       installPlanApproval: Manual
       name: network-operator
           sourceNamespace: openshift-marketplace
   

5. Create the subscription object by running the following command:

   $ oc create -f network-operator-sub.yaml
   

6. Change to the network-operator project:

   $ oc project network-operator
   

   To verify that the operator deployment is successful, run:

   $ oc get pods
   

   Example Output:

   NAME                                      READY   STATUS    RESTARTS   AGE
   
   vidia-network-operator-controller-manager-8f8ccf45c-zgfsq    2/2     Running   0          1
   

7. A successful deployment shows a Running status.
