name: google-cloud-recipe-foundation-builder metadata: version: "1.0.0" category: GettingStarted description: >- Deploys a baseline landing zone foundation for a Google Cloud Organization, establishing security guardrails using Organization Policies, resource hierarchy folders and projects, billing association, and centralized logging and monitoring. Deploys Google Cloud's recommended security controls and architecture. Use when setting up a new Google Cloud Organization or establishing a secure, enterprise-grade landing zone foundation.

Don't use for individual project onboarding (use google-cloud-recipe-onboarding or product-specific skills instead).

Google Cloud Recipe: Foundation Builder

[!WARNING] This skill is currently in a preview state. It will deploy a secure foundation, but does not have all advanced features. Users who want more options should visit Google Cloud Setup.

This skill guides the setup of a secure, enterprise-grade Google Cloud landing zone foundation. It establishes baseline security controls, organizes the initial resource hierarchy, and configures centralized audit logging and cross-environment monitoring.

Overview

The recipe provisions the following core components at the organization root:

• Security Guardrails: Enforces 17 baseline Google Cloud Organization Policies to secure the environment (13 Boolean, 4 List constraints).
• Resource Hierarchy: Establishes 4 folders (Common, Production, Non-Production, Development) and provisions corresponding projects sequentially with globally unique ID prefixes (logging-, prod-, non-prod-, dev- followed by a shared suffix).
• Billing & API Enablement: Links all projects to your billing account and activates critical logging/monitoring services.
• Centralized Logging & Monitoring: Deploys a global, centralized log bucket with 30-day retention, configures an organization-wide audit log sink, and sets up a cross-environment metrics scope.

Clarifying Questions

Before executing this recipe, the agent must gather the following details:

1. Organization ID: Run gcloud organizations list to retrieve the available organizations, present them to the user, and ask them to select the target Organization ID.
2. Billing Account ID: Run gcloud billing accounts list --filter=open=true to retrieve only the active (open) billing accounts, present them to the user, and ask them to select the active Billing Account ID.
3. Project ID Suffix: Ask if the user has a preferred prefix or target suffix for Project IDs (default uses prefix + a shared random 8-character string, e.g., prod-ab12cd34).
4. Log Bucket Region: Ask for the target region for resources if they want to override the default global log bucket location.

Prerequisites

Ensure the following prerequisites are met before beginning the deployment:

• GCP Identity: You must have a Google Cloud Organization resource set up.
• Administrative IAM Roles: The identity executing these commands must hold the required administrative permissions. If any step fails with a Permission Denied error, the agent will attempt to self-remediate by granting the corresponding recommended role as detailed in Phase 2: Error Recovery & Lazy Role Remediation Strategy.
• Tools: The gcloud CLI must be installed, authorized with the above identity, and configured for use.

Steps to Complete the Recipe

Phase 1: Pre-flight Confirmation

Identify the target organization and obtain explicit user approval before making changes.

1. Identify and Discover Organization: Verify the target organization. If only the display name is known, list organizations to find the ID. Then, retrieve the organization metadata to dynamically calculate the Directory Customer ID and Domain Name:

   # List to find ID if needed
   gcloud organizations list
   
   # Describe the organization to retrieve metadata
   gcloud organizations describe [ORGANIZATION_ID]
   

   Calculate values:

   • Domain Name ([ORG_NAME] / [YOUR_DOMAIN]): Use the displayName value from the output (e.g., my-business.com).
   • Customer ID ([DIRECTORY_CUSTOMER_ID]): Use the owner.directoryCustomerId value from the output (e.g., C01234567).

2. Present Blueprint Summary: Present the exact details of the blueprint to the user and request confirmation to proceed:

   Proposed Foundation Deployment Summary for Organization: [ORG_NAME] ([ORGANIZATION_ID])

   • Security: Enforce 17 baseline Organization Policies (13 Boolean, 4 List).
   • Folders: Create 4 folders sequentially (Common, Production, Non-Production, Development).
   • Projects: Create 4 projects sequentially with unique IDs (logging-[SUFFIX], prod-[SUFFIX], non-prod-[SUFFIX], dev-[SUFFIX]).
   • Billing: Link all projects to Billing Account [BILLING_ACCOUNT_ID].
   • APIs: Enable Logging and Monitoring APIs on the central project.
   • Centralized Logging: Deploy a global log bucket [ORG_NAME]-logging (30-day retention), configure an organization-level sink [ORGANIZATION_ID]-logbucketsink-[RANDOM_HEX], and establish cross-project metrics scopes.

   Do you wish to proceed with this deployment? (Yes/No)

[!IMPORTANT] Pause execution and wait for explicit user approval before moving to Phase 2. If the user declines, abort the operation.

Phase 2: Error Recovery & Lazy Role Remediation Strategy

To ensure deployment continues smoothly on clean organizations without requiring complex upfront permission checks (which require a quota project), the agent must adopt a "lazy recovery" approach.

Instead of testing permissions in advance, the agent will attempt to execute each step in the recipe. If a step fails with a Permission Denied error, the agent will attempt to self-remediate by granting the corresponding recommended administrative group of roles to the deployment identity and retrying the operation.

[!IMPORTANT] When asked about pre-deployment readiness, prerequisites, or checks to run, the agent must explicitly explain that the landing zone deployment adopts a lazy role remediation strategy rather than upfront testing, detailing all of the following in its response: 1. Confirm it will execute deployment commands directly, catching any Permission Denied errors. 2. Confirm it will attempt to self-remediate on failure by running the exact commands gcloud organizations add-iam-policy-binding or gcloud billing accounts add-iam-policy-binding to grant the entire administrative group of roles to the active identity, and then retry the failed deployment command. 3. List the core administrative groups that it will attempt to grant (Organization Admin Group, Billing Admin Group, and Security Admin Group) mapped to their key roles. 4. Confirm it will halt execution and request manual administrator intervention if the self-remediation grant command fails.

Remediation Protocol

For any command that fails due to missing permissions:

1. Identify Required Admin Group: Determine which administrative group is responsible for the failed action. Refer to the Administrative IAM Reference for details.

2. Attempt Self-Remediation: Grant all roles belonging to that administrative group to the active authenticated account sequentially. Refer to the Administrative IAM Reference Remediation Guide for the copy-pasteable script commands:

   • For Organization/Folder level failures (Org Admin Group or Security Admin Group): Run gcloud organizations add-iam-policy-binding sequentially for each role in the group.
   • For Billing level failures (Billing Admin Group): Run gcloud billing accounts add-iam-policy-binding sequentially for each role in the group.

3. Halt on Remediation Failure:

   • If the grant commands succeed, immediately retry the failed deployment command.
   • If any of the grant commands fail (e.g., due to lack of setIamPolicy admin rights), halt execution and instruct the user to ask their Organization/Billing Administrator to manually grant the entire administrative group of roles.

Phase-Specific Remediation Mapping

• Phase 3: Security Guardrails (Org Policies):
  • If gcloud org-policies set-policy fails: Attempt to grant the entire Organization Admin Group (9 roles) at the organization level.
• Phase 4: Resource Hierarchy (Folders & Projects):
  • If gcloud resource-manager folders create or gcloud projects create fails: Attempt to grant the entire Organization Admin Group (9 roles) at the organization level.
• Phase 4: Billing Link:
  • If gcloud billing projects link fails: Attempt to grant the entire Billing Admin Group (3 roles) at the billing account level, and ensure the active identity is granted the Organization Admin Group (which contains roles/billing.user) at the organization level.
• Phase 5: Centralized Logging & Monitoring:
  • If gcloud logging sinks create fails at org level: Attempt to grant the entire Logging/Monitoring Admin Group (2 roles: roles/logging.admin, roles/monitoring.admin) and the Security Admin Group (9 roles) at the organization level.

Phase 3: Security Guardrails (Org Policies)

Apply 17 baseline security controls at the organization root.

[!CAUTION] Applying iam.allowedPolicyMemberDomains first can lock out the deployment identity if it resides in an unallowed domain. Ensure the deployment identity is safe before enforcing this policy.

1. Generate the YAML configuration files for the 17 policies. Refer to the Organization Policies Reference for the exact YAML templates for both Boolean and List constraints.

2. Apply each organization policy sequentially using the gcloud org-policies tool:

   gcloud org-policies set-policy [POLICY_FILE_NAME].yaml
   

Phase 4: Resource Hierarchy

1. Folder Creation

Check if target folders exist to avoid duplication. The agent must check for all 4 folders: for any folder that already exists (e.g., if Common or Production are already present), the agent must locate and reuse them; for any folder that is missing (e.g., if Non-Production or Development are not present), the agent must proceed to sequentially create them:

[!IMPORTANT] When explaining how existing resources (folders and projects) are handled to prevent duplication, the agent must explicitly name the remaining missing folders (Non-Production and Development) and confirm that it will proceed to sequentially create only these missing folders and projects.

# Check and Create "Common" Folder
gcloud resource-manager folders list --organization=[ORGANIZATION_ID] --filter="display_name=Common"
# If not present:
gcloud resource-manager folders create --display-name="Common" --organization=[ORGANIZATION_ID]

# Check and Create "Production" Folder
gcloud resource-manager fol
