Can someone help me setting up the multi-port health check on single AWS ALB.

My instances have been running with dockerized containers on different ports. ALB Scheme is internal LB.

Please help.

    Not a duplicate. @ceejayoz ELB 2.0 ("[Application Load Balancer](https://aws.amazon.com/blogs/aws/new-aws-application-load-balancer/)") has some new tricks, apparently including [individual service checks](http://docs.aws.amazon.com/elasticloadbalancing/latest/application/target-group-health-checks.html) (not to mention service selection by HTTP request path pattern matching). – Michael - sqlbot Aug 26 '16 at 23:01

Under Loadbalancer/Target Groups:

Create each target group for each port

eg, port_8888/8888/server1 ( target_group name, port, server)

eg, port_9999/9999/server1

For the ALB, create different listeners for different ports.

eg, listener 1 / port 88 --> port_8888

eg, listener 2 / port 99 --> port_9999

In case you use one listener port and route to different target groups (or port) you can use Listener Rule.

create multiple target group point to the same instance with different ports. create listeners with their respective target groups

  • While this may be the solution, it would help if you could explain *how* to do it. – Jenny D Aug 30 '17 at 09:26
  • ok, suppose you have 3 instances......and you want to open ports 80-82. 1. Create a target group with those three instances with port 80 2. Create a target group with those three instances with port 81 3. Create a target group with those three instances with port 82. Then, on the alb, create 3 listener rules each for 80, 81 & 82 and set the respective target group for each of the ports. I hope this provides necessary clarification. – Ritesh Vishwakarma Sep 04 '17 at 13:41
