** Please be patient while the chart is being deployed **
1. HAproxy has been started. You can find out the port numbers being used by HAProxy by running:

2. Get HAProxy's load balancer IP/hostname:
NOTE: It may take a few minutes for this to become available.
You can watch the status by running:
$ kubectl get svc haproxy --namespace default -w
Once 'EXTERNAL-IP' is no longer '<pending>':
$ kubectl describe svc haproxy --namespace default | grep Ingress | awk '{print $3}'
3. Configure DNS records corresponding to Kubernetes ingress resources to point to the load balancer IP/hostname found in step 3
