Installing the SR-IOV Network Operator

You can install the Single Root I/O Virtualization (SR-IOV) Network Operator on your cluster to manage SR-IOV network devices and network attachments.

Installing the SR-IOV Network Operator

As a cluster administrator, you can install the Single Root I/O Virtualization (SR-IOV) Network Operator by using the OKD CLI or the web console.

CLI: Installing the SR-IOV Network Operator

As a cluster administrator, you can install the Operator using the CLI.

Prerequisites

• A cluster installed on bare-metal hardware with nodes that have hardware that supports SR-IOV.

• Install the OpenShift CLI (oc).

• An account with cluster-admin privileges.

Procedure

1. To create the openshift-sriov-network-operator namespace, enter the following command:

   $ cat << EOF| oc create -f -
   apiVersion: v1
   kind: Namespace
   metadata:
     name: openshift-sriov-network-operator
     annotations:
       workload.openshift.io/allowed: management
   EOF

2. To create an OperatorGroup CR, enter the following command:

   $ cat << EOF| oc create -f -
   apiVersion: operators.coreos.com/v1
   kind: OperatorGroup
   metadata:
     name: sriov-network-operators
     namespace: openshift-sriov-network-operator
   spec:
     targetNamespaces:
     - openshift-sriov-network-operator
   EOF

3. Subscribe to the SR-IOV Network Operator.

   1. Run the following command to get the OKD major and minor version. It is required for the channel value in the next step.

      $ OC_VERSION=$(oc version -o yaml | grep openshiftVersion | \
          grep -o '[0-9]*[.][0-9]*' | head -1)

   2. To create a Subscription CR for the SR-IOV Network Operator, enter the following command:

      $ cat << EOF| oc create -f -
      apiVersion: operators.coreos.com/v1alpha1
      kind: Subscription
      metadata:
        name: sriov-network-operator-subscription
        namespace: openshift-sriov-network-operator
      spec:
        channel: "${OC_VERSION}"
        name: sriov-network-operator
        source: redhat-operators
        sourceNamespace: openshift-marketplace
      EOF

4. To verify that the Operator is installed, enter the following command:

   $ oc get csv -n openshift-sriov-network-operator \
     -o custom-columns=Name:.metadata.name,Phase:.status.phase

   Example output

   Name                                         Phase
   sriov-network-operator.4.14.0-202310121402   Succeeded

Web console: Installing the SR-IOV Network Operator

As a cluster administrator, you can install the Operator using the web console.

Prerequisites

• A cluster installed on bare-metal hardware with nodes that have hardware that supports SR-IOV.

• Install the OpenShift CLI (oc).

• An account with cluster-admin privileges.

Procedure

1. Install the SR-IOV Network Operator:

   1. In the OKD web console, click Operators → OperatorHub.

   2. Select SR-IOV Network Operator from the list of available Operators, and then click Install.

   3. On the Install Operator page, under Installed Namespace, select Operator recommended Namespace.

   4. Click Install.

2. Verify that the SR-IOV Network Operator is installed successfully:

   1. Navigate to the Operators → Installed Operators page.

   2. Ensure that SR-IOV Network Operator is listed in the openshift-sriov-network-operator project with a Status of InstallSucceeded.

      During installation an Operator might display a Failed status. If the installation later succeeds with an InstallSucceeded message, you can ignore the Failed message.

      If the Operator does not appear as installed, to troubleshoot further:

      • Inspect the Operator Subscriptions and Install Plans tabs for any failure or errors under Status.

      • Navigate to the Workloads → Pods page and check the logs for pods in the openshift-sriov-network-operator project.

      • Check the namespace of the YAML file. If the annotation is missing, you can add the annotation workload.openshift.io/allowed=management to the Operator namespace with the following command:

        $ oc annotate ns/openshift-sriov-network-operator workload.openshift.io/allowed=management

        For single-node OpenShift clusters, the annotation workload.openshift.io/allowed=management is required for the namespace.
