Readiness gate question

[Maksym Fedchyshyn]

Hello Everyone,

I'm trying to setup readinessGate by following up on this reference: https://github.com/kubernetes-sigs/aws-alb-ingress-controller/blob/master/docs/guide/ingress/pod-conditions.md.

I see a new pod being available in the target group in web UI, however its READINESS GATES value is still zero in CLI output:

```

> kubectl get pod <POD_NAME> -o wide

NAME                                      READY   STATUS    RESTARTS   AGE   IP              NODE                           NOMINATED NODE   READINESS GATES

<POD_NAME>   2/2     Running   0          18m   100.XX.XX.137   ip-100-XX-XX-41.ec2.internal   <none>           0/1

```

the debugging command listed in documentation returns nothing:

kubectl get pod <POD_NAME> -o yaml | grep -B5 'type: target-health'  

I'm running alb-ingress-controller v 1.1.8 and EKS 1.17.

Any advice on how to debug that? 

Thanks!
