12.14. Configuring kube-proxy

Procedure

1. Edit the Network.operator.openshift.io custom resource (CR) by running the following command:

   $ oc edit network.operator.openshift.io cluster

2. Modify the kubeProxyConfig parameter in the CR with your changes to the kube-proxy configuration, such as in the following example CR:

   apiVersion: operator.openshift.io/v1
   kind: Network
   metadata:
     name: cluster
   spec:
     kubeProxyConfig:
       iptablesSyncPeriod: 30s
       proxyArguments:
         iptables-min-sync-period: ["30s"]

3. Save the file and exit the text editor.

   The syntax is validated by the oc command when you save the file and exit the editor. If your modifications contain a syntax error, the editor opens the file and displays an error message.

4. Enter the following command to confirm the configuration update:

   $ oc get networks.operator.openshift.io -o yaml

   Example output

   apiVersion: v1
   items:
   - apiVersion: operator.openshift.io/v1
     kind: Network
     metadata:
       name: cluster
     spec:
       clusterNetwork:
       - cidr: 10.128.0.0/14
         hostPrefix: 23
       defaultNetwork:
         type: OpenShiftSDN
       kubeProxyConfig:
         iptablesSyncPeriod: 30s
         proxyArguments:
           iptables-min-sync-period:
           - 30s
       serviceNetwork:
       - 172.30.0.0/16
     status: {}
   kind: List

5. Optional: Enter the following command to confirm that the Cluster Network Operator accepted the configuration change:

   $ oc get clusteroperator network

   Example output

   NAME      VERSION     AVAILABLE   PROGRESSING   DEGRADED   SINCE
   network   4.1.0-0.9   True        False         False      1m

   The AVAILABLE field is True when the configuration update is applied successfully.
