SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill simplifies the complex task of managing Google Cloud Platform (GCP) Identity and Access Management (IAM) policies, ensuring that users and services have only the necessary permissions to perform their functions.

Core Features & Use Cases

  • Policy Generation: Creates least-privilege IAM policy bindings for projects, folders, and organizations.
  • Role Management: Assists in defining and creating custom IAM roles with specific permissions.
  • Service Account Management: Facilitates the creation and management of service accounts and their associated permissions.
  • Workload Identity Federation: Configures secure access for external workloads (e.g., GitHub Actions, AWS) to GCP resources.
  • IAM Conditions: Implements granular access control using conditions based on time, resource attributes, or IP addresses.
  • Deny Policies: Establishes explicit denials for specific actions or principals to enforce security guardrails.
  • Use Case: You need to grant a new CI/CD pipeline read-only access to a specific Cloud Storage bucket in your project without granting broader permissions. This Skill can generate the precise IAM policy binding and condition required.

Quick Start

Use the gcp-iam skill to generate a project-level IAM policy binding that grants the 'roles/viewer' role to the service account '[email protected]' on project 'my-project'.

Frequently Asked Questions about gcp-iam

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

FAQPage Schema
How do I generate least-privilege IAM policies for a GCP service account?▼

To generate least-privilege IAM policies for a GCP service account, this tool creates precise role bindings and IAM conditions that restrict access to only necessary resources. It configures project-level permissions without granting broader access.

What is the best way to configure workload identity federation for external workloads accessing GCP?▼

Configuring workload identity federation for external workloads accessing GCP is handled by generating secure IAM bindings that connect external identity providers like GitHub Actions to GCP resources. This establishes authenticated access without managing long-lived keys.

Can I create custom GCP IAM roles with specific permissions?▼

Yes, you can create custom GCP IAM roles with specific permissions. The tool assists in defining and generating custom roles tailored to your exact requirements, ensuring granular access control for your principals.

How do I use IAM conditions to restrict access based on IP address or time?▼

To use IAM conditions to restrict access based on IP address or time, the tool implements granular access control policies. It generates conditional bindings that evaluate resource attributes, time constraints, or IP addresses before authorizing requests.

Can I establish explicit deny policies in GCP IAM to enforce security guardrails?▼

Yes, you can establish explicit deny policies in GCP IAM to enforce security guardrails. The tool generates deny policies that explicitly block specific actions or principals, overriding default allow permissions to maintain strict security boundaries.

How do I grant a CI/CD pipeline read-only access to a specific Cloud Storage bucket?▼

To grant a CI/CD pipeline read-only access to a specific Cloud Storage bucket, the tool generates a precise IAM policy binding with the required roles and conditions. This restricts the service account to only the specified bucket without broader project access.
