Antrea cluster doesnt show in NSX UI

Products

• VMware Container Networking with Antrea

Issue/Introduction

• Antrea NSX integration doesn't show the cluster on the NSX UI. 
• VKr 1.35.2, vSphere 9.0, VKS 3.6.2
• NSX >> Inventory >> Containers >> Cluster >> Blank.

Environment

VCF 9

Cause

VKr1.34 and below used AntreaConfig.yaml, whereas VKr1.35.2 was implemented with AddonConfig.yaml.

Resolution

• If the VKr1.35 and above AddonConfig has to be used for the Antrea NSX integration. 
  
  Sample AddonConfig yaml

apiVersion: addons.kubernetes.vmware.com/v1alpha1
kind: AddonConfig
metadata:
  name: cluster1-antrea
  namespace: workload-clusters
spec:
  addonConfigDefinitionRef:
    name: antrea.tanzu.vmware.com.2.5.1---vmware.2-tkg.1
    namespace: vmware-system-vks-public
  clusterName: cluster1
  values:
    antreaNSX:
      enable: true

• If the VKr1.34 and below AntreaConfig has to be used for the Antrea NSX integration.
  
  Sample AntreaConfig yaml

#AntreaConfig.yaml
apiVersion: cni.tanzu.vmware.com/v1alpha1
kind: AntreaConfig
metadata:
name:tkgs-cluster-name-antrea-package #prefix required
namespace:tkgs-cluster-ns
