AWS Elastic Load Balancer (ELB) Terraform module

Terraform module which creates ELB resources on AWS.

These types of resources are supported:

• ELB
• ELB Attachment

Root module calls these modules which can also be used separately to create independent resources:

• elb - creates ELB
• elb_attachment - creates ELB attachment

Usage

module "elb_http" {
  source = "terraform-aws-modules/elb/aws"

  name = "elb-example"

  subnets         = ["subnet-12345678", "subnet-87654321"]
  security_groups = ["sg-12345678"]
  internal        = false

  listener = [
    {
      instance_port     = "80"
      instance_protocol = "HTTP"
      lb_port           = "80"
      lb_protocol       = "HTTP"
    },
  ]

  health_check = [
    {
      target              = "HTTP:80/"
      interval            = 30
      healthy_threshold   = 2
      unhealthy_threshold = 2
      timeout             = 5
    },
  ]

  access_logs = [
    {
      bucket = "my-access-logs-bucket"
    },
  ]

  // ELB attachments
  number_of_instances = 2
  instances           = ["i-06ff41a77dfb5349d", "i-4906ff41a77dfb53d"]
  
  tags = {
    Owner       = "user"
    Environment = "dev"
  }
}

Examples

• Complete ELB example

Known Issues/Limitations

• Support for HTTPS is a common requirment for Internet facing ELBs. However, there is a known Terraform limitation with providing a dynamic computed value for the ssl_id_certificate parameter in nested block structures (Refer to: hashicorp/terraform#16582 (comment)).
