A Terraform module to create an AWS new style Load Balancer (ALB/NLB) and associated resources.
terraform-aws-alb A Terraform module containing common configurations for an AWS new style Load Balancer (ALB/NLB). Available through the terraform registry. NOTE: There has been significant changes to the upstream module and this README has not been updated yet. | Branch | Build status | | --- | --- | | master |  | | master (upstream) |  | Assumptions You want to create a set of resources for the ALB: namely an associated target group and listener. You've created a Virtual Private Cloud (VPC) + subnets where you intend to put this ALB. You have one or more security groups to attach to the ALB. You want to configure a listener for HTTPS/HTTP You've
