AWS ALB terraform module

Build Status

This module creates AWS Application Load Balancer as per provided parameters.

As some more resources - security-group and listener are required when creating AWS ALB, these are also created (based on passed parameters).

This module will output AWS ALB's dns_name and listener_arn which can be used to integrate with it.

Module Input Variables

  • name - (string) - REQUIRED - The name of the ALB. This name must be unique within your AWS account, can have a maximum of 32 characters, must contain only alphanumeric characters or hyphens, and must not begin or end with a hyphen
  • vpc_id - (string) - REQUIRED - The id of the VPC that the ALB should be placed in
  • subnet_ids - (list) - REQUIRED - A list of subnet IDs to attach to the ALB
  • certificate_domain_name - (string) - REQUIRED - Domain name as used in AWS ACM Certificate - this will be used by Terraform Data Source to resolve the actual certificate ARN
  • default_target_group_arn - (string) - REQUIRED - The ARN of the default Target Group to which to route traffic
  • internal - (bool) - OPTIONAL - If true, the ALB will be internal; default: true
  • extra_security_groups - (list) - OPTIONAL - Extra security groups to be attached to ALB
  • tags - (map) - OPTIONAL - Map of tags to be applied to the resources (just to ALB as ALB Listeners cannot be tagged); default: {} (empty - no tags)

Usage

module "alb_test" {
  source  = "mergermarket/alb/acuris"
  version = "2.0.0"

  # required
  name                     = "foobar-alb"
  vpc_id                   = "vpc-2f09a348"
  subnet_ids               = ["subnet-b46032ec", "subnet-ca4311ef", "subnet-ba881221"]
  default_target_group_arn = "arn:aws:elasticloadbalancing:us-east-1:123456789012:targetgroup/my-targets/73e2d6bc24d8a067"
  certificate_domain_name  = "*.acuris.com"
}

Outputs

  • alb_dns_name - The DNS name of the load balancer
  • alb_listener_arn - The ARN of the load balancer
