SNS Email Topic Terraform Module

Introduction

Although Terraform supports most of the AWS SNS resource options you'll need sometimes you'll want to set up a notification topic that uses the email or email-json protocols. When using either of those an email is sent to the given address that needs to be confirmed out of bounds, which isn't really the model that Terraform wants, or should, support.

This thin wrapper module creates an SNS email topic using a tiny CloudFormation stack and exposes the topics ARN back to, and through, Terraform

Usage

Use the module in your terraform files:

module "admin-sns-email-topic" {
  source = "github.com/deanwilson/tf_sns_email"

  display_name  = "Example.org Admin Notifications"
  email_address = "admin@example.org"
  owner         = "Example.org:Admin"
  stack_name    = "admin-sns-email"
}

and then run a terraform init to download the module.

Once you've applied it you can check the value with

terraform output -module=admin-sns-email-topic arn

Tagging

You can apply additional tags to CloudFormation stack that terraform creates using the additional_tags input when calling the module.

additional_tags = {
  "RunFrom" = "Jenkins",
  "Level"   = "SENSITIVE"
}
