NOTES

• Adjust NodeSelector in values.yaml as needed. If you do not wish to use it, just replace with nodeSelector: {}. Otherwise, add a label to a node for ntp:ntp.
• Change IP addres '10.0.8.222' to an IP address within your Load Balancer IP pool range.
• Change 'jh' to whatever namespace you want.
• Spin up/down replicaCount as you see fit.
• Modify ntpServers using your favorite time servers.
