Flexible load balancer for Service

[imdkbj]

I want to create one load balancer in one service and then import this in another service and assign there service, port, conditions etc...

So basically, One load balancer to serve all ecs spread over different repo.

abc.com/a1 - Service1>Container1
abc.com/a2 - Service1>Container2
abc.com/a3 - Service2>Container1
abc.com/a4 - Service3>Container1

Routing can be done via path or header
So only one endpoint will be exposed to serve traffic from all micro-service.

Tried
I have tried serviceRegistry for the same but api gateway is throwing random 503 error (INTEGRATION_NETWORK_FAILURE) on high load.
