Terraform Credential Helper With Scalr

##Added scalr-demo.scalr.io as the remote backend##
terraform {
  backend "remote" {
    hostname = "scalr-demo.scalr.io"
    organization = "org-ssccu6d5ch61234"

    workspaces {
      name = "CredHelper"
    }
  }
}

##Added a module that is being pulled from docs.scalr.io##
module "module-ec2" {
	source = "docs.scalr.io/env-t568vsij9i12345/module-ec2/aws"
	version = "0.0.4"

	# Set 1 required variable below.

 	instance_type = "t2.nano"
}

credentials_helper "scalr" {}

The name of the credential does not need to be “scalr”, it can be whatever you want, but it will need to match the name used in the next step when creating the terraform-credentials-<some_name> file.

<workspace>/terraform.d/plugins/terraform-credentials-scalr

In this case, we named terraform-credentials-scalr to match the naming of credentials_helper "scalr" {} in the terraformrc file, but again, any name can be appended to it: terraform-credentials-<some_name>

The contents of terraform-credentials-scalr:

#!/bin/bash
command="$1"
host="$2"
env_token="TF_TOKEN_${host//./_}"
if [ "$command" = "get" ]; then
  if  [ -z "${!env_token}" ]; then
    echo "{}"e
  else
    echo "{ \"token\": \"${!env_token}\" }"
  fi
  exit 0
else
  exit 1
fi

Then, export the token for the module registry where the code will be pulled from, in this case, it is the token from docs.scalr.io. If you notice, the format will always be TF_TOKEN_the_url:

export TF_TOKEN_docs_scalr_io=eyJh…

Initializing modules...
Downloading docs.scalr.io/env-t568vsij9123456/module-ec2/aws 0.0.4 for module-ec2...
- module-ec2 in .terraform/modules/module-ec2

Initializing the backend...

Initializing provider plugins...
- Using previously-installed hashicorp/aws v4.4.0

The following providers do not have any version constraints in configuration,
so the latest version was installed.

To prevent automatic upgrades to new major versions that may contain breaking
changes, we recommend adding version constraints in a required_providers block
in your configuration, with the constraint strings suggested below.

* hashicorp/aws: version = "~> 4.4.0"

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.
