Terraform module to create an AWS Application Load Balancer, with listener

terraform_aws_alb

Module terraform_aws_alb creates an AWS Application Load Balancer (ALB), and a matching listener.

The module includes a default target group that can be used to put instances into, however lacks health checks. To take full advantage of this module, it's suggested that you use the companion terraform_aws_asg module found here:

https://github.com/paybyphone/terraform_aws_asg

This module also depends on the terraform_aws_security_group module found here:

https://github.com/paybyphone/terraform_aws_security_group

Finally, you may also be interested in the terraform_aws_vpc module found here:

Usage Example:

module "vpc" {
  source                  = "github.com/paybyphone/terraform_aws_vpc?ref=VERSION"
  vpc_network_address     = "10.0.0.0/24"
  public_subnet_addresses = ["10.0.0.0/25", "10.0.0.128/25"]
  project_path            = "your/project"
}

module "alb" {
  source              = "github.com/paybyphone/terraform_aws_alb?ref=VERSION"
  listener_subnet_ids = ["${module.vpc.public_subnet_ids}"]
  project_path        = "your/project"
}
