GCP Assets Inventory

In this example you are going to export some generic information about a GCP organization and all of its assets, to Port.

Here is the complete main.tf file:

To use this example yourself, simply replace the placeholders for domain, client_id, secret and credentials and then run the following commands to setup your new backend, create the new infrastructure and update the software catalog:

# install modules and create an initial state
terraform init
# To view Terraform's planned changes based on your .tf definition file:
terraform plan
# To apply the changes and update the catalog
terraform apply

GCP permissions

To be able to read the organization, folders, projects and assets in this example, you need to use an organization's GCP IAM role with at least the following permissions:

cloudasset.assets.searchAllResources
resourcemanager.folders.get
resourcemanager.folders.list
resourcemanager.organizations.get
resourcemanager.projects.get

Let's break down the definition file and understand the different parts:

Module imports

This part includes importing and setting up the required Terraform providers and modules:

terraform {
  required_providers {
    port = {
      source  = "port-labs/port-labs"
      version = "~> 1.0.0"
    }
    google-beta = {
      source  = "hashicorp/google-beta"
      version = ">= 3.53, < 5.0"
    }
  }
}

locals {
  domain = "GCP_ORGANIZATION_DOMAIN_NAME" # set the organization's domain
}

provider "port" {
  client_id = "PORT_CLIENT_ID"     # or set the env var PORT_CLIENT_ID
  secret    = "PORT_CLIENT_SECRET" # or set the env var PORT_CLIENT_SECRET
}

provider "google-beta" {
  credentials = "GOOGLE_APPLICATION_CREDENTIALS" # or set the env var GOOGLE_APPLICATION_CREDENTIALS
}

Extracting the organization, folders, projects and assets

This part includes defining the datasource for the organization, folders, projects and assets:

data "google_organization" "my_org" {
  provider   = google-beta
  domain = local.domain
}

data "google_cloud_asset_resources_search_all" "my_folder_assets" {
  provider = google-beta
  scope    = "organizations/${data.google_organization.my_org.org_id}"
  asset_types = [
    "cloudresourcemanager.googleapis.com/Folder"
  ]
}

data "google_folder" "my_folders" {
  for_each = {for idx, result in data.google_cloud_asset_resources_search_all.my_folder_assets.results : idx => result}
  folder = "folders/${reverse(split("/", each.value.name))[0]}"
}

data "google_projects" "my_projects" {
  provider   = google-beta
  filter = "parent.id:*"
}

data "google_cloud_asset_resources_search_all" "my_assets" {
  for_each = {for idx, result in data.google_projects.my_projects.projects: idx => result}
  provider = google-beta
  scope    = "projects/${each.value.project_id}"
}

Creating the Organization blueprint and the entity matching the organization

This part includes configuring the organization blueprint and creating an entity for the organization:

resource "port_blueprint" "gcp_org_blueprint" {
  title      = "Organization"
  icon       = "GCP"

  properties = {
    string_props = {
      "link" = {
        type   = "string"
        format = "url"
        title  = "Link"
      }
      "createTime" = {
        type   = "string"
        format = "date-time"
        title  = "Create Time"
      }
    }
  }
}


resource "port_entity" "gcp_org_entity" {
  identifier = data.google_organization.my_org.org_id
  title      = data.google_organization.my_org.domain
  blueprint  = port_blueprint.gcp_org_blueprint.identifier
  properties = {
    string_props = {
      "link"       = "https://console.cloud.google.com/welcome?organizationId=${data.google_organization.my_org.org_id}"
      "createTime" = data.google_organization.my_org.create_time
    }
  }
}

        title  = "Link"
      }
      "createTime" = {
        format = "date-time"
        title  = "Create Time"
      }
    }
  }
  relations = {
    "organization" = {
      title    = "Organization"
      target   = port_blueprint.gcp_org_blueprint.identifier
      required = false
      many     = false
    }
  }
}


resource "port_entity" "gcp_folder_entity" {
  for_each   = { for idx, folder in data.google_folder.my_folders : idx => folder }
  identifier = each.value.folder_id
  title      = each.value.display_name
  blueprint  = port_blueprint.gcp_folder_blueprint.identifier
  properties = {
    string_props = {
      "link"       = "https://console.cloud.google.com/welcome?folder=${each.value.folder_id}"
      "createTime" = each.value.create_time
    }
  }

    }
  }
}

  properties = {
    string_props = {
      "link" = {
        format = "url"
        title  = "Link"
      }
      "createTime" = {

    "folder" = {
      title    = "Folder"
      target   = port_blueprint.gcp_folder_blueprint.identifier
      many     = false
