Provision and update accounts using automation
You can provision or update individual accounts in AWS Control Tower by several methods:
-
You can provision and customize accounts with AWS Control Tower Account Factory for Terraform (AFT). For more information, see Overview of AWS Control Tower Account Factory for Terraform (AFT).
-
You can update accounts with Customizations for AWS Control Tower (CfCT). For more information, see Customizations for AWS Control Tower (CfCT) overview .
-
Script automation: If you prefer to use an API approach, you can update accounts using the API framework of Service Catalog and the AWS CLI to update the accounts in a batch process. You'd call the
UpdateProvisionedProductAPI of Service Catalog for each account. You can write a script to update the accounts, one by one, with this API. More information about this approach, when adding Regions for governance, is available in a blog post, Enabling guardrails in new AWS Regions. You can update as many as five (5) accounts at a time. You must wait for at least one account update to succeed before beginning the next account update. Therefore, the process may take a long time if you have a lot of accounts, but it is not complicated. For more information about this approach, see the Walkthrough: Automate Account Provisioning in AWS Control Tower by Service Catalog APIs.
Video walkthrough
The Video Walkthrough is designed for automated account
provisioning with a script, but the steps also apply to account updating. Use the
UpdateProvisionedProduct API instead of the ProvisionProduct
API.
A further step of automation by script is to check for Succeed status
of the AWS Control Tower UpdateLandingZone lifecycle event. Use it as a trigger to begin
updating individual accounts as described in the video. A lifecycle event marks the completion
of a sequence of activities, so the occurrence of this event means that a landing zone update
is complete. The landing zone update must be complete before account updates begin. For more
information about working with lifecycle events, see Lifecycle Events.
