Installing the Node Feature Discovery (NFD) Operator

The Node Feature Discovery (NFD) Operator is a prerequisite for the NVIDIA GPU Operator. Install the NFD Operator using the Red Hat OperatorHub catalog in the OpenShift Container Platform web console .

1. Follow the Red Hat documentation guidance in The Node Feature Discovery Operator to install the Node Feature Discovery Operator.

2. Verify the Node Feature Discovery Operator is running:

   $ oc get pods -n openshift-nfd
   

   NAME                                      READY   STATUS    RESTARTS   AGE
   nfd-controller-manager-7f86ccfb58-nqgxm   2/2     Running   0          11m
   

3. When the Node Feature Discovery is installed, create an instance of Node Feature Discovery using the NodeFeatureDiscovery tab.

1. Click Operators > Installed Operators from the side menu.

2. Find the Node Feature Discovery entry.

3. Click NodeFeatureDiscovery under the Provided APIs field.

4. Click Create NodeFeatureDiscovery.

5. In the subsequent screen click Create. This starts the Node Feature Discovery Operator that proceeds to label the nodes in the cluster that have GPUs.

   Note

   The values pre-populated by the OperatorHub are valid for the GPU Operator.

Verify that the Node Feature Discovery Operator is functioning correctly

The Node Feature Discovery Operator uses vendor PCI IDs to identify hardware in a node. NVIDIA uses the PCI ID 10de. Use the OpenShift Container Platform web console or the CLI to verify that the Node Feature Discovery Operator is functioning correctly.

1. In the OpenShift Container Platform web console, click Compute > Nodes from the side menu.

2. Select a worker node that you know contains a GPU.

3. Click the Details tab.

4. Under Node labels verify that the following label is present:

   feature.node.kubernetes.io/pci-10de.present=true
   

   Note

   0x10de is the PCI vendor ID that is assigned to NVIDIA.

5. Verify the GPU device (pci-10de) is discovered on the GPU node:

   $ oc describe node | egrep 'Roles|pci' | grep -v master
   

   Roles:              worker
                       feature.node.kubernetes.io/pci-10de.present=true
                       feature.node.kubernetes.io/pci-1d0f.present=true
   Roles:              worker
                       feature.node.kubernetes.io/pci-1013.present=true
                       feature.node.kubernetes.io/pci-8086.present=true
   Roles:              worker
                       feature.node.kubernetes.io/pci-1013.present=true
                       feature.node.kubernetes.io/pci-8086.present=true
   Roles:              worker
                       feature.node.kubernetes.io/pci-1013.present=true
                       feature.node.kubernetes.io/pci-8086.present=true
