Procedure

1. Install the Ingress Node Firewall Operator:

   1. In the OpenShift Container Platform web console, click Operators OperatorHub.
   2. Select Ingress Node Firewall 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 Ingress Node Firewall Operator is installed successfully:

   1. Navigate to the Operators Installed Operators page.

   2. Ensure that Ingress Node Firewall Operator is listed in the openshift-ingress-node-firewall project with a Status of InstallSucceeded.

      Note

      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 have a Status of InstallSucceeded, troubleshoot using the following steps:

      • Inspect the Operator Subscriptions and Install Plans tabs for any failures or errors under Status.
      • Navigate to the Workloads Pods page and check the logs for pods in the openshift-ingress-node-firewall 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-ingress-node-firewall workload.openshift.io/allowed=management

        Note

        For single-node OpenShift clusters, the openshift-ingress-node-firewall namespace requires the workload.openshift.io/allowed=management annotation.
