Dynamically capturing Rancher LB Ports

1

Hi,

I have a rancher environment stack setup. It’s a typical 3 tier infrastructure. I have Rancher LB’s fronting the containers at each level in the stack. The containers are connected using --links.

I have 2 questions .

  1. For the frontend rancher LB, I’ve exposed a host port - how to I dynamically allocate that to an AWS ELB ?
  2. For the internal Rancher LBs I need to programmatically return the dynamic port that has been assigned for communication within the stack

i.e

         Rancher LB ( Fixed port exposed to host - this will be assigned to an AWS ELB ) 
                |
      Presentation Layer
                | 
    Business Layer Rancher LB ( Dynamic Port exposed to host; how does the presentation layer know which 
                                                port to use )
                | 
     Business Layer
                | 
    Data Tier Rancher LB ( Dynamic Port exposed to host; how does the Business layer know which 
                                                port to use )
                | 
     Data Layer

Thanks in advance
