terraform-aws-organization-access-group

Terraform module to create an IAM Group and Policy to grant permissions to delegated IAM users in the Organization's master account to access a member account

https://docs.aws.amazon.com/organizations/latest/userguide/orgs_manage_accounts_access.html

This project is part of our comprehensive "SweetOps" approach towards DevOps.

It's 100% Open Source and licensed under the APACHE2.

We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!

Introduction

By default, when you create a member account as part of your Organization, AWS automatically creates OrganizationAccountAccessRole in the member account.

The role grants admin permissions to access the member account to delegated IAM users in the master account.

In the master account you need to create a Policy to grant permissions to IAM users to assume OrganizationAccountAccessRole in the member account.

This module does the following:

Creates an IAM Group
Adds the provided IAM users to the Group
Creates a Policy to grant permissions to the IAM users in the master account to assume OrganizationAccountAccessRole in the member account
Attaches the Policy to the Group

Users who are members of the Group will be able to assume the role and administer the member account by going here:

(change XXXXXXXXXXXX to the ID of the member account)

https://signin.aws.amazon.com/switchrole
                ?account=XXXXXXXXXXXX
                &roleName=OrganizationAccountAccessRole
                &displayName=Dev

NOTE: Member accounts that you invite to join your Organization (that are not part of your Organization) do not automatically get OrganizationAccountAccessRole created. You can use terraform-aws-organization-access-role module to create OrganizationAccountAccessRole role in an invited member account.

Usage

module "organization_access_group" {
  source            = "git::https://github.com/cloudposse/terraform-aws-organization-access-group.git?ref=master"
  namespace         = "cp"
  stage             = "dev"
  name              = "cluster"
  user_names        = ["User1","User2"]
  role_arns         = {
    "cp@dev" = "arn:aws:iam::XXXXXXXXX:role/OrganizationAccountAccessRole"
  }
  require_mfa       = "true"
}
