# SkillPatch skill: google-cloud-recipe-foundation-builder

This skill automates the deployment of a secure, enterprise-grade Google Cloud landing zone foundation for a Google Cloud Organization. It enforces baseline Organization Policies, establishes a resource hierarchy with folders and projects, configures billing, and sets up centralized audit logging and cross-environment monitoring. It is intended for initial organization setup, not individual project onboarding.

You (the agent) were given this URL and asked to use this skill. This is a **public** skill — no SkillPatch account, API key, or prior setup is required. Two ways to use it:

**1. Use it right now** — the skill's complete file tree (SKILL.md + all reference files) is inlined below; read `SKILL.md` first, then follow it, consulting the other files as it directs.

**2. Install the exact package onto disk** (recommended if you can run a shell — this reproduces the skill byte-for-byte, including any binary assets that can't be inlined):

```bash
mkdir -p .claude/skills/google-cloud-recipe-foundation-builder
curl -sSL https://skillpatch.dev/install_skill/google-cloud-recipe-foundation-builder | tar -xz -C .claude/skills/
```

(`.claude/skills/` is Claude Code's convention; use whatever directory your agent loads skills from.)

# 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](https://docs.cloud.google.com/docs/enterprise/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**:

    ```bash
    # 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](references/admin-iam.md#core-administrative-groups--roles)
    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](references/admin-iam.md#remediation)
    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](references/org-policies.md) for the exact
    YAML templates for both Boolean and List constraints.
2.  Apply each organization policy sequentially using the `gcloud org-policies`
    tool:

    ```bash
    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.

```bash
# 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 folders list --organization=[ORGANIZATION_ID] --filter="display_name=Production"
# If not present:
gcloud resource-manager folders create --display-name="Production" --organization=[ORGANIZATION_ID]

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

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

#### 2. Project Creation and Billing Link

Check if target projects already exist in the folders by matching their display
names. If not present, generate a shared 8-character random suffix (e.g.,
`ab12cd34`) and create the projects sequentially, linking billing and enabling
APIs immediately:

```bash
# Check if "central-logging-monitoring" project exists in Common folder
gcloud projects list --filter="parent.id=[COMMON_FOLDER_ID] AND parent.type=folder AND name=central-logging-monitoring"

# If not present: Create, link billing, and enable APIs
gcloud projects create logging-[SUFFIX] --name="central-logging-monitoring" --folder=[COMMON_FOLDER_ID]
gcloud billing projects link logging-[SUFFIX] --billing-account=[BILLING_ACCOUNT_ID]
gcloud services enable compute.googleapis.com logging.googleapis.com monitoring.googleapis.com --project=logging-[SUFFIX]

# Check if "production" project exists in Production folder
gcloud projects list --filter="parent.id=[PRODUCTION_FOLDER_ID] AND parent.type=folder AND name=production"

# If not present: Create, link billing, and enable APIs
gcloud projects create prod-[SUFFIX] --name="production" --folder=[PRODUCTION_FOLDER_ID]
gcloud billing projects link prod-[SUFFIX] --billing-account=[BILLING_ACCOUNT_ID]
gcloud services enable compute.googleapis.com run.googleapis.com container.googleapis.com artifactregistry.googleapis.com firestore.googleapis.com pubsub.googleapis.com aiplatform.googleapis.com cloudaicompanion.googleapis.com apphub.googleapis.com designcenter.googleapis.com discoveryengine.googleapis.com iam.googleapis.com config.googleapis.com cloudbuild.googleapis.com cloudasset.googleapis.com cloudkms.googleapis.com cloudresourcemanager.googleapis.com --project=prod-[SUFFIX]

# Check if "non-production" project exists in Non-Production folder
gcloud projects list --filter="parent.id=[NON_PRODUCTION_FOLDER_ID] AND parent.type=folder AND name=non-production"

# If not present: Create, link billing, and enable APIs
gcloud projects create non-prod-[SUFFIX] --name="non-production" --folder=[NON_PRODUCTION_FOLDER_ID]
gcloud billing projects link non-prod-[SUFFIX] --billing-account=[BILLING_ACCOUNT_ID]
gcloud services enable compute.googleapis.com run.googleapis.com container.googleapis.com artifactregistry.googleapis.com firestore.googleapis.com pubsub.googleapis.com aiplatform.googleapis.com cloudaicompanion.googleapis.com apphub.googleapis.com designcenter.googleapis.com discoveryengine.googleapis.com iam.googleapis.com config.googleapis.com cloudbuild.googleapis.com cloudasset.googleapis.com cloudkms.googleapis.com cloudresourcemanager.googleapis.com --project=non-prod-[SUFFIX]

# Check if "development" project exists in Development folder
gcloud projects list --filter="parent.id=[DEVELOPMENT_FOLDER_ID] AND parent.type=folder AND name=development"

# If not present: Create, link billing, and enable APIs
gcloud projects create dev-[SUFFIX] --name="development" --folder=[DEVELOPMENT_FOLDER_ID]
gcloud billing projects link dev-[SUFFIX] --billing-account=[BILLING_ACCOUNT_ID]
gcloud services enable compute.googleapis.com run.googleapis.com container.googleapis.com artifactregistry.googleapis.com firestore.googleapis.com pubsub.googleapis.com aiplatform.googleapis.com cloudaicompanion.googleapis.com apphub.googleapis.com designcenter.googleapis.com discoveryengine.googleapis.com iam.googleapis.com config.googleapis.com cloudbuild.googleapis.com cloudasset.googleapis.com cloudkms.googleapis.com cloudresourcemanager.googleapis.com --project=dev-[SUFFIX]
```

> [!NOTE] **Agentic Parallelism Option**: While the manual runbook enforces
> sequential project execution to avoid terminal race conditions, an AI agent
> with multi-agent orchestration capability may optionally spawn subagents to
> provision the 4 projects in parallel once folder IDs are resolved.

### Phase 5: Centralized Logging and Monitoring

Configure centralized audit logging and cross-project monitoring scope in the
`logging-[SUFFIX]` project.

Refer to the
[Centralized Logging and Monitoring Reference](references/logging-monitoring.md)
for the detailed step-by-step commands to:

1.  Create the central log bucket.
2.  Create the organization-wide log sink.
3.  Grant required IAM permissions to the log sink.
4.  Configure the cross-project monitoring metrics scope.

--------------------------------------------------------------------------------

## Validation Logic & Checklist

Evaluate the deployment against the following verification checks:

-   [ ] **Security Policies**: Run `gcloud org-policies list
    --organization=[ORGANIZATION_ID]` and verify all 17 target policies are
    enforced or correctly configured.
-   [ ] **Resource Folders**: Verify folders `Common`, `Production`,
    `Non-Production`, and `Development` exist under the organization root.
-   [ ] **Billing Linkage**: Run `gcloud billing projects list` and assert that
    all 4 newly created projects are linked to your billing account.
-   [ ] **Log Bucket & Retention**: Verify the log bucket `[ORG_NAME]-logging`
    exists in project `logging-[SUFFIX]`, is located in `global`, and has a
    retention period of exactly 30 days.
-   [ ] **Log Sink Routing**: Run `gcloud logging sinks describe` at the
    organization level and confirm the sink routes cloud audit logs to the
    global bucket and holds standard `writerIdentity` credentials.
-   [ ] **Metrics Scope Linkage**: Run `gcloud beta monitoring metrics-scopes
    describe` and assert that the `dev`, `non-prod`, and `prod` projects appear
    in the monitored list of the central `logging` project.

## Core Administrative Groups & Roles

The recipe aligns with Google Cloud's enterprise setup recommendations by
verifying roles belonging to **4 core administrative groups** (Org Admin,
Billing Admin, Logging/Monitoring Admin, and Security Admin):

### 1. Organization Admin Group (9 Roles)

Responsible for broad administrative controls, folder management, project
creation, and billing link permissions:

-   `roles/resourcemanager.organizationAdmin` (Organization Administrator)

-   `roles/resourcemanager.organizationViewer` (Organization Viewer)

### 3. Logging/Monitoring Admin Group (2 Unique Roles)

Configures global logging policies, audit log exports, and centralized metrics
monitoring:

-   `roles/logging.admin` (Logging Administrator)
-   `roles/monitoring.admin` (Monitoring Administrator)

### 4. Security Admin Group (9 Unique Roles)

Audits compliance, sets up security command center, manages keys, and reviews
service accounts:

-   `roles/iam.securityAdmin` (Security Administrator)
-   `roles/iam.securityReviewer` (Security Reviewer)

-   `roles/container.viewer` (Kubernetes Engine Viewer)
-   `roles/compute.viewer` (Compute Viewer)

## Permission-to-Role Mapping Table

If any permissions are missing from the command outputs, they map directly to
specific roles that should be sequentially granted to the deployment identity:

Resource            | Missing Permission                           | Recommended Role to Grant
:------------------ | :------------------------------------------- | :------------------------
**Organization**    | `resourcemanager.organizations.setIamPolicy` | `roles/resourcemanager.organizationAdmin` (Org Admin)
**Organization**    | `resourcemanager.folders.create`             | `roles/resourcemanager.folderAdmin` (Folder Admin)
**Organization**    | `resourcemanager.projects.create`            | `roles/resourcemanager.projectCreator` (Project Creator)
**Organization**    | `iam.roles.create`                           | `roles/iam.organizationRoleAdmin` (IAM Org Role Admin)
**Organization**    | `orgpolicy.policy.set`                       | `roles/orgpolicy.policyAdmin` (Org Policy Admin)

**Billing Account** | `billing.accounts.update`                    | `roles/billing.admin` (Billing Account Administrator)

--------------------------------------------------------------------------------

## Remediation

When a command fails with a `Permission Denied` error, identify the associated
role from the mapping table and determine its **Administrative Group**. Attempt
to sequentially grant **all** roles in that group to the deployment identity.

### 1. Organization Admin Group (9 roles)

If organization, folder, project, or policy creation fails:

```bash
for role in roles/resourcemanager.organizationAdmin roles/resourcemanager.folderAdmin roles/resourcemanager.projectCreator roles/billing.user roles/iam.organizationRoleAdmin roles/orgpolicy.policyAdmin roles/securitycenter.admin roles/cloudsupport.admin roles/pubsub.admin; do
    gcloud organizations add-iam-policy-binding [ORGANIZATION_ID] \
        --member="user:[YOUR_ACCOUNT_EMAIL]" \
        --role="$role"
done
```

### 2. Billing Admin Group (3 roles)

If billing project link fails, grant at the billing account level:

```bash
for role in roles/billing.admin roles/billing.creator roles/resourcemanager.organizationViewer; do
    gcloud billing accounts add-iam-policy-binding [BILLING_ACCOUNT_ID] \
        --member="user:[YOUR_ACCOUNT_EMAIL]" \
        --role="$role"
done
```

And also ensure the active identity has `roles/billing.user` (which is part of
the Organization Admin Group) at the organization level.

### 3. Logging/Monitoring Admin Group (2 roles)

If logging configuration or metrics scope linking fails:

```bash
for role in roles/logging.admin roles/monitoring.admin; do
    gcloud organizations add-iam-policy-binding [ORGANIZATION_ID] \
        --member="user:[YOUR_ACCOUNT_EMAIL]" \
        --role="$role"
done
```

### 4. Security Admin Group (9 roles)

If security reviews or folder IAM failures occur:

```bash
for role in roles/iam.securityAdmin roles/iam.securityReviewer roles/iam.serviceAccountCreator roles/iam.organizationRoleViewer roles/resourcemanager.folderIamAdmin roles/logging.privateLogViewer roles/logging.configWriter roles/container.viewer roles/compute.viewer; do
    gcloud organizations add-iam-policy-binding [ORGANIZATION_ID] \
        --member="user:[YOUR_ACCOUNT_EMAIL]" \
        --role="$role"
done
```

# Centralized Logging and Monitoring

This reference guide details the step-by-step commands to configure centralized
audit logging and cross-project monitoring scope in the central
`logging-[SUFFIX]` project.

### 1. Create Central Log Bucket

Create a log bucket named `[ORG_NAME]-logging` (substituting your organization
name domain, e.g., `example-com-logging`) in the `logging-[SUFFIX]` project. The
default location is `global` and retention is set to 30 days:

```bash
gcloud logging buckets create [ORG_NAME]-logging \
    --project=logging-[SUFFIX] \
    --location=global \
    --retention-days=30 \
    --description="Central logging and monitoring bucket"
```

### 2. Create Organization Log Sink

Create the organization-level audit log sink. Format the sink name as
`[ORGANIZATION_ID]-logbucketsink-[RANDOM_4_HEX]` (replace with a random 4-digit
hex string):

```bash
gcloud logging sinks create [ORGANIZATION_ID]-logbucketsink-[RANDOM_4_HEX] \
    logging.googleapis.com/projects/logging-[SUFFIX]/locations/global/buckets/[ORG_NAME]-logging \
    --organization=[ORGANIZATION_ID] \
    --log-filter='logName: /logs/cloudaudit.googleapis.com%2Factivity OR logName: /logs/cloudaudit.googleapis.com%2Fsystem_event OR logName: /logs/cloudaudit.googleapis.com%2Fdata_access OR logName: /logs/cloudaudit.googleapis.com%2Faccess_transparency'
```

*Save the `writerIdentity` (service account) returned in the command output.*

### 3. Grant IAM Permissions to the Log Sink

> [!IMPORTANT] This step grants security-sensitive bucket writing permissions at
> the project level. Review the service account identity carefully.

Grant the sink's service account the `bucketWriter` role on the logging project:

```bash
gcloud projects add-iam-policy-binding logging-[SUFFIX] \
    --member=[SINK_SERVICE_ACCOUNT_IDENTITY] \
    --role=roles/logging.bucketWriter
```

### 4. Configure Monitoring Metrics Scope

Initialize and link projects to the central monitoring metrics scope. Use
`describe` first to avoid attempting to link already scoped projects:

```bash
# Check existing metrics scope linkages
gcloud beta monitoring metrics-scopes describe locations/global/metricsScopes/logging-[SUFFIX]

# Review the monitoredProjects list. If missing, link the environment projects:

# Link Development project
gcloud beta monitoring metrics-scopes create projects/dev-[SUFFIX] --project=logging-[SUFFIX]

# Link Non-Production project
gcloud beta monitoring metrics-scopes create projects/non-prod-[SUFFIX] --project=logging-[SUFFIX]

# Link Production project
gcloud beta monitoring metrics-scopes create projects/prod-[SUFFIX] --project=logging-[SUFFIX]
```

## Overview of Constraints

The baseline security posture enforces Boolean constraints (set to Enforced) and
List constraints (restricting allowed or denied values).

--------------------------------------------------------------------------------

## Enforced Boolean Constraints

These policies are binary and are set to `enforce: true`.

### Target YAML Structure

For all Boolean constraints, use the following YAML template. Replace
`[ORGANIZATION_ID]` and `[CONSTRAINT_NAME]` accordingly.

```yaml
name: organizations/[ORGANIZATION_ID]/policies/[CONSTRAINT_NAME]
spec:
  rules:
  - enforce: true
```

### List of Boolean Constraints

1.  **Disable Automatic IAM Grants for Default Service Accounts**
    *   **Constraint:** `iam.automaticIamGrantsForDefaultServiceAccounts`
    *   **Description:** Prevents the default App Engine and Compute Engine
        service accounts from automatically being granted the Editor role on
        your projects.
2.  **Public Access Prevention**
    *   **Constraint:** `storage.publicAccessPrevention`
    *   **Description:** Enforces public access prevention on all Cloud Storage
        buckets in the organization, blocking public access via IAM policies.
3.  **Set New Project Default to Zonal DNS Only**
    *   **Constraint:** `compute.setNewProjectDefaultToZonalDNSOnly`
    *   **Description:** Ensures that new projects use only zonal DNS names for
        Compute Engine instances, preventing internal DNS name leakage across
        zones.
4.  **Uniform Bucket-Level Access**
    *   **Constraint:** `storage.uniformBucketLevelAccess`
    *   **Description:** Enforces uniform bucket-level access on all Cloud
        Storage buckets, disabling fine-grained ACLs and relying solely on IAM.
5.  **Restrict Public IP Access for Cloud SQL**
    *   **Constraint:** `sql.restrictPublicIp`
    *   **Description:** Prevents Cloud SQL instances from being created with
        public IP addresses, enforcing private IP connectivity.
6.  **Disable Service Account Key Creation**
    *   **Constraint:** `iam.disableServiceAccountKeyCreation`
    *   **Description:** Prevents users from creating new external service
        account keys, reducing the risk of credential leakage.
7.  **Disable Serial Port Access**
    *   **Constraint:** `compute.disableSerialPortAccess`
    *   **Description:** Disables serial port access to all Compute Engine
        virtual machine instances, securing the console access.
8.  **Restrict Shared VPC Project Lien Removal**
    *   **Constraint:** `compute.restrictXpnProjectLienRemoval`
    *   **Description:** Restricts the removal of liens on host projects for
        Shared VPC, preventing accidental deletion of critical networking
        projects.
9.  **Disable VPC External IPv6**
    *   **Constraint:** `compute.disableVpcExternalIpv6`
    *   **Description:** Prevents the allocation of external IPv6 addresses to
        VPC subnets and resources, limiting external exposure.
10. **Disable Nested Virtualization**
    *   **Constraint:** `compute.disableNestedVirtualization`
    *   **Description:** Disables hardware-assisted nested virtualization on
        Compute Engine VMs, mitigating side-channel attack vectors.
11. **Disable Service Account Key Upload**
    *   **Constraint:** `iam.disableServiceAccountKeyUpload`
    *   **Description:** Prevents users from uploading public keys to service
        accounts, blocking external key association.
12. **Require OS Login**
    *   **Constraint:** `compute.requireOsLogin`
    *   **Description:** Enforces OS Login on all Compute Engine instances,
        linking VM SSH access to the user's Google identity.
13. **Restrict Authorized Networks for Cloud SQL**
    *   **Constraint:** `sql.restrictAuthorizedNetworks`
    *   **Description:** Blocks the addition of non-private IP ranges to the

          - INTERNAL
    ```

### Allowed Policy Member Domains (Allow Customer ID)

*   **Constraint:** `iam.allowedPolicyMemberDomains`
*   **Description:** Restricts the domain identities that can be added to IAM
    policies to your specific Google Workspace or Cloud Identity customer ID.
*   **YAML Template:**

    ```yaml
    name: organizations/[ORGANIZATION_ID]/policies/iam.allowedPolicyMemberDomains
    spec:
      rules:
      - values:
          allowedValues:
          - [DIRECTORY_CUSTOMER_ID] # Replace with your numeric customer ID (e.g., C01234567)
    ```

    *(Note: Alternatively, you can use the principal set format:
    `principalSet://iam.googleapis.com/organizations/[ORGANIZATION_ID]`)*

--------------------------------------------------------------------------------

## Deployment Directive

Apply these policies sequentially using the `gcloud org-policies set-policy`
command:

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

> [!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.
