module-aws-terraform-deploy-fingerprint

We manage a lot of AWS environments across many git repos and sometimes it can be tricky for figure out what version of your code has been applied to an enviroment. A simple way to keeping track of this is to store the git commit id somewhere when a terraform apply gets done.

This module grabs the git commit id from the calling terraform code and makes it avaible as an output of the modle. This output can be stored as a SSM parameter or in your state file.

Example Usage

some_terraform.tf

module "fingerprint" {
   source = "git::https://github.com/phzietsman/module-aws-terraform-deploy-fingerprint.git?ref=master"
}

resource "aws_ssm_parameter" "fingerprint" {
  name  = "infrastructure_fingerprint"
  type  = "String"
  value = "${module.fingerprint.output}"
}
