2.5. Resetting the IP family policy for application pods and services

Procedure

1. Set the spec.ipFamilyPolicy field to a valid value for dual-stack networking in your service or pod by using the following example:

   Example dual-stack network configuration for a service

   kind: Service
   apiVersion: v1
   metadata:
     name: microshift-new-service
     labels: app: microshift-application
   spec:
     type: NodePort
     ipFamilyPolicy: `PreferDualStack`

   # ...

   Required. Valid values for dual-stack networking are PreferDualStack and RequireDualStack. The value you set depends on the requirements of your application. PreferSingleStack is the default value for the ipFamilyPolicy field.

2. Restart any application pods that do not have a hostNetwork defined. Pods that do have a hostNetwork defined do not need to be restarted to update the ipFamilyPolicy value.
