** 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:

    $ kubectl describe svc haproxy --namespace default
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

WARNING: There are "resources" sections in the chart not set. Using "resourcesPreset" is not recommended for production. For production installations, please set the following values according to your workload needs:
