kubernetes service discovery for multi-cluster kubernetes and haproxy as GLSB

[cervajs]

Question

i have following use case/scenario

• One main DC (DC1) . center of star network topology
• DC2 to DCX (i.e. 5)
• DCs are connected on L3 layer
• HAProxy in main DC as GSLB
• Consul cluster on VMs in DC1
• One or more Kubernetes clusters in every DC
• web application i.e. webapp1 spread through multiple Kubernetes clusters(DCs) - multiAZ availability
• consul-k8s syncCatalog in every cluster synced to central Consul cluster

example

DC1 subnet 192.168.1.0/24
DC2 subnet 192.168.2.0/24,  kubernetes cluster2 (3 worker nodes)
DC3 subnet 192.168.3.0/24,  kubernetes cluster3 (2 worker nodes)

webapp1 is running in 4 replicas

worker2 (192.168.2.21), worker3(192.168.2.22) in cluster2
worker1(192.168.3.20),worker2(192.168.3.21) in cluster3

so the question is is it possible export Kubernetes webapp1 services with their respective worker IP addresses to consul?
HAProxy can then read it from Consul and route traffic to the right backends.

i.e.
