# Dynamically generate per-service VIP data based on EnabledServices
# This works as follows (outer->inner functions)
# yaql - filters services where no mapping exists in ServiceNetMap
# map_replace: substitute e.g internal_api with the IP from NetIpMap
# map_replace: substitute e.g heat_api_network with network name from ServiceNetMap
# map_merge/repeat: generate a per-service mapping
- yaql:
# This filters any entries where the value hasn't been substituted for
# a list, e.g it's still $service_network. This happens when there is
# no network defined for the service in the ServiceNetMap, which is OK
# as not all services have to be bound to a network, so we filter them
