About

Terraform module to run AWS ALB

Features:

• A security group to allow incoming connection from Internet and outgoing connection to private subnets

Usage

module "loadbalancer" {
  source             = "github.com/jetbrains-infra/terraform-aws-alb?ref=vX.X.X" // see https://github.com/jetbrains-infra/terraform-aws-alb/releases
  name               = "demo"
  target_cidr_blocks = [local.private_cidr_blocks]
  public_subnets     = [module.vpc.subnet_public_1, module.vpc.subnet_public_2]
  certificate_arn    = module.alb_certificate.arn
}

All params:

module "loadbalancer" {
  source             = "github.com/jetbrains-infra/terraform-aws-alb?ref=vX.X.X" // see https://github.com/jetbrains-infra/terraform-aws-alb/releases
  name               = "demo"
  target_cidr_blocks = [local.private_cidr_blocks]
  https_ports        = [443]
  http_ports         = [80]
  public_subnets     = [module.vpc.subnet_public_1, module.vpc.subnet_public_2]
  idle_timeout       = 60
  certificate_arn    = module.alb_certificate.arn // see https://github.com/jetbrains-infra/terraform-aws-acm-certificate
  access_log_bucket  = module.s3_logs.bucket_id // see https://github.com/jetbrains-infra/terraform-aws-s3-bucket-for-logs
  access_log_prefix  = module.s3_logs.alb_logs_path
  tags = {
    Name   = "FooBar",
    Module = "ECS Cluster"
  }
}

NB! You need to allow the incoming traffic from ALB subnets to targets into a private subnet(s).

Outputs

• arn - load balancer ARN
• dns_name - ALB domain name
• dns_zone_id - ALB domain zone id
