Consul-Terraform-Sync Module for AWS Application Load Balancer Listener Rules

terraform-aws-listenerrule-nia

This module for Consul Terraform Sync creates a listener rule to be added to an application load balancer. The listener rules offer a way to change weights between blue and green instances of application.

The module register targets by IP address to account for multi-region load balancing.

Note: The module currently parses the DNS name of the node from Consul to register the primary IP address with the target group. This is because instances can have multiple IP addresses on different interfaces. Unless you bind Consul clients to the primary interface or the IP addresses on other interfaces are routable, you might have some connectivity issues. This is particularly the case with EKS.
