About The Project

My opinionated label module.

This Terraform module consumes my terraform-null-context and produces consistent names and tags for all of my resources. It implements a strict naming and tagging convention that follows the format from cloudposse/terraform-null-label.

The Cloud Posse label module provides detailed documentation and reasoning however by itself it has too many knobs and provides more options that I use. This module configures the Cloud Posse label exactly how I like it while taking advantage of my context module to carry standard part of the label around.

Usage

module "context" {
  source    = "bendoerr-terraform-modules/context/null"
  version   = "xxx"
  namespace = "bd"
  role      = "production"
  region    = "us-east-1"
  project   = "example"
}

module "label" {
  source  = "bendoerr-terraform-modules/label/null"
  version = "xxx"
  context = module.context.shared
  name    = "function"
}

resource "aws_lambda_function" "function" {
  function_name = module.label.id   # bd-prd-ue1-example-function
  tags          = module.label.tags # { Name: bd-prd-ue1-example-function,
                                    #   Namespace: bd,
                                    #   Role: production,
                                    #   Region: us-east-1,
                                    #   Project: example,
                                    #   Environment: prod-ue1,
                                    # }
  ...
}

resource "aws_route53_record" "function" {
  name = "${module.label.dns_name}.${vars.zone_name}" # function.ue1.cloud.bendoerr.me
                                                      # assuming vars.zone_name = cloud.bendoerr.me
  ...
}
