Tenant IPs

• tenant IPs are stored in ips.txt
• These are used to create the number of services and the number of replicas for a statefulset (1 tenantip = 1 pod)

Create Services

• Running ./update-service.sh a for the first time will create the services
• The files ips.txt contains the list of clusterIPs to set, which also creates a label and selector
• Passing an a or b will update the selector to use the pods in group a or b
