# The runtime Channel "greeting" in the InteractionTopology, realized as a
# Kubernetes Service that fronts the consumer Pico Pod on port 8080.
#
# Under Phase 7 the Service is the concrete pathway that carries the one
# event (an EventType "hello.greeting" payload) from the producer Pico to
# the consumer Pico. The topology fragment (topology.yaml, and the ConfigMap
# in 04-topology-configmap.yaml) is the declarative truth; this Service is
# how that Channel is realized on the Kubernetes substrate.
#
# The selector points at hello-consumer-pico only: the consumer is the
# subscriber, so the Channel address MUST resolve to its Pod.
