8.5. Create pods that have IPv6 connectivity on RHOSP

Procedure

1. Define pods that use your IPv6 namespace and the annotation k8s.v1.cni.cncf.io/networks: <additional_network_name>, where <additional_network_name is the name of the additional network. For example, as part of a Deployment object:

   apiVersion: apps/v1
   kind: Deployment
   metadata:
     name: hello-openshift
     namespace: ipv6
   spec:
     affinity:
       podAntiAffinity:
         requiredDuringSchedulingIgnoredDuringExecution:
            - labelSelector:
               matchExpressions:
               - key: app
                 operator: In
                 values:
                 - hello-openshift
     replicas: 2
     selector:
       matchLabels:
         app: hello-openshift
     template:
       metadata:
         labels:
           app: hello-openshift
         annotations:
           k8s.v1.cni.cncf.io/networks: ipv6
       spec:
         securityContext:
           runAsNonRoot: true
           seccompProfile:
             type: RuntimeDefault
         containers:
         - name: hello-openshift
           securityContext:
             allowPrivilegeEscalation: false
             capabilities:
               drop:
               - ALL
           image: quay.io/openshift/origin-hello-openshift
           ports:
           - containerPort: 8080

2. Create the pod. For example, on a command line, enter the following command:

   $ oc create -f <ipv6_enabled_resource> 

   1

   1

   Specify the file that contains your resource definition.
