Overview
Google Cloud Platform (GCP) offers powerful tools for managing Identity and Access Management (IAM) permissions across projects. This guide explores how to efficiently transfer IAM configurations between GCP projects using the Command Line Interface (CLI), covering export options in YAML and JSON formats, and providing step-by-step instructions for moving and verifying permissions.
Prerequisites for IAM Transfer
Before initiating the IAM permission transfer process, ensure you have the Google Cloud SDK installed and properly initialized on your local machine. For more information on how to set this up, please see my blog post entitled, “How to Set Up the Google Cloud SDK Locally and Authenticate via IAM”! You must also possess sufficient permissions to manage IAM policies in both the source and destination projects. It’s crucial to have the necessary roles, such as “Security Admin” (roles/iam.securityAdmin), to execute get-iam-policy and set-iam-policy commands effectively. Familiarize yourself with the project IDs of both the source and destination projects, as these will be required throughout the transfer process.
Authenticating with Google Cloud CLI
To authenticate with Google Cloud Platform (GCP) using the command line interface (CLI), the primary method is the gcloud auth login command. This command initiates an interactive process that allows users to authorize gcloud to…
