• Terraform
  • This module was created using Terraform 0.11.6 on 2018/04/10
  • The latest stable version of Terraform which this module tested working is Terraform 0.12.0 on 2019/05/28

For most of the resources, AWS does not allow us to create multiple resources with the same name. That is the reason why we need to make them unique.

This module will help you to generate a unique resource name by adding random_id value as a suffix to the name prefix you specified. Not just adding, but this module will also calculate how many random characters should be added to the prefix so it will not exceed maximum character allowed from AWS. Check the list below for AWS services supported by this module.

Notes:

• If character length of your name prefix already exceeds maximum character allowed from AWS, this module will not do anything about it. Executing terraform apply will most likely to fail.

You need to know what resource you want to provision (resource_type) and what the name prefix (name_prefix) is. Then provide the information to this module's variables:

provider "random" {
  version = ">= 1.2.0, < 3.0.0"
}

module "aws-resource-naming_lambda_role" {
  source        = "github.com/traveloka/terraform-aws-resource-naming"
  version       = "v0.17.1"
  name_prefix   = "LambdaRole_DailyScheduler"
  resource_type = "iam_role"
}

resource "aws_iam_role" "lambda_role" {
  name        = "${module.aws-resource-naming_lambda_role.name}"
  path        = "/lambda-role/"                                       
  description = "Lambda Role for Daily Scheduler"

  assume_role_policy   = "${data.aws_iam_policy_document.lambda_assume_role_policy.json}"
}

data "aws_iam_policy_document" "lambda_assume_role_policy" {
  statement = {
    actions = ["sts:AssumeRole"]
    effect  = "Allow"

    principals = {
      type        = "Service"
      identifiers = ["lambda.amazonaws.com"]
    }
  }
}
