title: Terragrunt Global Variables
body: <p>So I have a set of like 30 inputs that are shared between all projects. I'm wondering the best way to share them in all the terragrunt.hcl files with out having to copy them a million different places. I currently use yaml files for some overrides. I was wondering what the best practices are. </p>
  
  <pre><code>    locals {
        manager           = "devops"                             # default contact
        company_id        = "moos3"                                 # any string to identify the company for better resources naming. Keep max size of five chars.
        default_yaml_path = find_in_parent_folders("empty.yaml") # terragrunt function. read the file content for better explanation.
        enabled_api_services = [                                 # APIs enabled by default for all projects when created
          "compute.googleapis.com",
          "cloudkms.googleapis.com",
          "cloudresourcemanager.googleapis.com",
          "logging.googleapis.com",
          "monitoring.googleapis.com",
          "serviceusage.googleapis.com",
          "storage-api.googleapis.com",
        ]
        gcp_billing_account    = "*****************" # gcp billing account where projects will be created
        gcp_org_id             = "*****************"         # gcp organization id where resources will be created
        gcp_seed_project_id    = "my-seed"               # initial seed project where terraform state bucket will be created
        region                 = "us-east1"              # default region for shared services
        stack                  = "global"                # architectural stack name
     }
  </code></pre>
  
  <p>It would be nice to just include a module to include those or load them from a centralized path. As these thing won't change often.</p>
