SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Cloud environments often drift into risky configurations because individual projects can enable public IPs, weak IAM practices, or unapproved regions. This Skill provides the commands, Terraform code, and verification steps to enforce organization-wide guardrails in GCP so security policies apply consistently at organization, folder, and project levels.

Core Features & Use Cases

  • Essential Security Constraints: Ready-to-use policies for blocking VM external IPs, restricting resource locations, disabling service account key creation, requiring OS Login, and enforcing uniform bucket-level access.
  • Terraform and gcloud Implementations: Apply constraints via infrastructure-as-code or CLI, including dry-run testing with Policy Intelligence before enforcement.
  • Misconfiguration Detection: Guidance for auditing dry-run-only policies, child overrides that weaken org guardrails, and inverted list constraints using effective-policy queries.
  • Use Case: A security engineer needs to prevent any VM in the organization from receiving a public IP. Use this Skill to set the compute.vmExternalIpAccess deny policy at the org level, test it in dry-run mode, and verify enforcement with Cloud Asset Inventory.

Quick Start

Ask the AI to generate a GCP organization policy that denies external IP addresses on all VMs and show how to verify it is enforced.

Frequently Asked Questions about implementing-gcp-organization-policy-constraints

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I restrict external IP addresses on GCP VMs?▼

Set the compute.vmExternalIpAccess list constraint with allValues set to DENY at the organization level using gcloud org-policies set-policy or a Terraform google_organization_policy resource. Verify enforcement with gcloud org-policies describe using the --effective flag.

How to enforce GCP organization policies with Terraform?▼

Use the google_organization_policy resource with the org_id and constraint name, then define a list_policy or boolean_policy block. Folder-level exceptions use google_folder_organization_policy with specific allowed values.

Why is my GCP organization policy not being enforced?▼

Common causes include the policy existing only as a dry-run spec, a child project overriding it with inheritFromParent set to false, or a boolean constraint declared with enforced set to false. Also allow up to 15 minutes for policy propagation before concluding enforcement failed.

Can I test GCP org policies before enforcing them?▼

Yes, create a dry-run policy by adding dryRunSpec: true to the policy YAML. This logs would-be violations without blocking resources, letting you assess impact with Policy Intelligence tools before live enforcement.

What IAM role is needed to manage GCP organization policies?▼

You need the Organization Policy Administrator role (roles/orgpolicy.policyAdmin) on the organization, plus the gcloud CLI authenticated. Terraform-based management requires equivalent permissions for the service account used.
