Installing the SR-IOV Network Operator

To manage SR-IOV network devices and network attachments on your cluster, install the Single Root I/O Virtualization (SR-IOV) Network Operator. By using this Operator, you can centralize the configuration and lifecycle management of your SR-IOV resources.

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.

Using the CLI to install the SR-IOV Network Operator

You can use the CLI to install the SR-IOV Network Operator. By using the CLI, you can deploy the Operator directly from your terminal to manage SR-IOV network devices and attachments without navigating the web console.

Prerequisites

  • You installed the OpenShift CLI (oc).

  • You have an account with cluster-admin privileges.

  • You installed a cluster on bare-metal hardware, and you ensured that cluster nodes have hardware that supports SR-IOV.

Procedure

  1. Create the openshift-sriov-network-operator namespace by entering 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. Create an OperatorGroup custom resource (CR) by entering 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. Create a Subscription CR for the SR-IOV Network Operator by entering 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: stable
  name: sriov-network-operator
  source: redhat-operators
  sourceNamespace: openshift-marketplace
EOF

  4. Create an SriovoperatorConfig resource by entering the following command:

    $ cat <<EOF | oc create -f -
apiVersion: sriovnetwork.openshift.io/v1
kind: SriovOperatorConfig
metadata:
  name: default
  namespace: openshift-sriov-network-operator
spec:
  enableInjector: true
  enableOperatorWebhook: true
  logLevel: 2
  disableDrain: false
EOF
Verification

  • To verify that the Operator is installed, enter the following command and then check that the output shows Succeeded for the Operator:

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

Using the web console to install the SR-IOV Network Operator

To install the SR-IOV Network Operator, use the web console. By using the web console, you can deploy the Operator and manage SR-IOV network devices and attachments directly from a graphical interface without having to the CLI.

Prerequisites

  • You have an account with cluster-admin privileges.

  • You installed a cluster on bare-metal hardware, and you ensured that cluster nodes have hardware that supports SR-IOV.

Procedure

  1. Install the SR-IOV Network Operator:

    1. In the OKD web console, click Ecosystem → Software Catalog.

    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.

Verification

  1. Navigate to the Ecosystem → 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.

  3. If the Operator does not show as installed, complete any of the following steps to troubleshoot the issue:

    • 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.
