Chapter 8. Configuring the node port service range

Procedure

1. To expand the node port range, enter the following command. Replace <port> with the largest port number in the new range.

   $ oc patch network.config.openshift.io cluster --type=merge -p \
     '{
       "spec":
         { "serviceNodePortRange": "30000-<port>" }
     }'

   Tip

   You can alternatively apply the following YAML to update the node port range:

   apiVersion: config.openshift.io/v1
   kind: Network
   metadata:
     name: cluster
   spec:
     serviceNodePortRange: "30000-<port>"

2. To confirm that the configuration is active, enter the following command. It can take several minutes for the update to apply.

   $ oc get configmaps -n openshift-kube-apiserver config \
     -o jsonpath="{.data['config\.yaml']}" | \
     grep -Eo '"service-node-port-range":["[[:digit:]]+-[[:digit:]]+"]'
