Python Client for IAM Policy Troubleshooter

image image image

IAM Policy Troubleshooter makes it easier to understand why a user has access to a resource or doesn’t have permission to call an API. Given an email, resource, and permission, Policy Troubleshooter examines all Identity and Access Management (IAM) policies that apply to the resource. It then reveals whether the member’s roles include the permission on that resource and, if so, which policies bind the member to those roles.

Quick Start

In order to use this library, you first need to go through the following steps:

  1. Select or create a Cloud Platform project.

  2. Enable billing for your project.

  3. Enable the Resource Manager API Service.

  4. Setup Authentication.


Install this library in a virtualenv using pip. virtualenv is a tool to create isolated Python environments. The basic problem it addresses is one of dependencies and versions, and indirectly permissions.

With virtualenv, it’s possible to install this library without needing system install permissions, and without clashing with the installed system dependencies.


pip install virtualenv
virtualenv <your-env>
source <your-env>/bin/activate
<your-env>/bin/pip install google-cloud-policy-troubleshooter


pip install virtualenv
virtualenv <your-env>
<your-env>\Scripts\pip.exe install google-cloud-policy-troubleshooter
