AWS ALB terraform module

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
