This demo shows how to enable sticky learn session persistence for an Ingress resource with the sessions shared among multiple NGINX Plus Ingress Controller pods.
- Deploy the Ingress Controller as a deployment -- https://github.com/nginxinc/kubernetes-ingress/blob/master/docs/installation.md
- Deploy a headless service for the Ingress Controller that will be used for zone synchronization:
$ kubectl apply -f nginx-ingress-zonesync.yaml
