AWS Network Load Balancer
Configure the AWS Network Load Balancer like this:
The load balancer listens on port 31032 (but it could be another TCP port).
The listeners are configured to forward on to a specific target group. The target group has three worker nodes registered to bind on NodePort 31032. This is specific to the Ingress Controller service port for ODBC. For a basic health check, ping the specified TCP port.
