Deploys AWS ssosync to sync Google Groups with AWS SSO.

AWS ssosync is a Lambda application that regularly manages Identity Store users.

This component requires manual deployment by a privileged user because it deploys a role in the root or identity management account.

Usage

You should be able to deploy the aws-ssosync component to the same account as aws-sso. Typically that is the core-gbl-root or gbl-root stack.

Stack Level: Global Deployment: Must be deployed by managers or SuperAdmin using atmos CLI

The following is an example snippet for how to use this component:

(stacks/catalog/aws-ssosync.yaml)

components:
  terraform:
    aws-ssosync:
      vars:
        enabled: true
        name: aws-ssosync
        google_admin_email: an-actual-admin@acme.com
        ssosync_url_prefix: "https://github.com/Benbentwo/ssosync/releases/download"
        ssosync_version: "2.0.2"
        google_credentials_ssm_path: "/ssosync"
        log_format: text
        log_level: debug
        schedule_expression: "rate(15 minutes)"

We recommend following a similar process to what the AWS ssosync documentation recommends.

Deployment

Overview of steps:

Configure AWS IAM Identity Center
Configure Google Cloud console
Configure Google Admin console
Deploy the aws-ssosync component
Deploy the aws-sso component

1. Configure AWS IAM Identity Center (AWS SSO)

Follow AWS documentation to configure SAML and SCIM with Google Workspace and IAM Identity Center.

As part of this process, save the SCIM endpoint token and URL. Then in AWS SSM Parameter Store, create two SecureString parameters in the same account used for AWS SSO. This is usually the root account in the primary region.

/ssosync/scim_endpoint_access_token
/ssosync/scim_endpoint_url

One more parameter you'll need is your Identity Store ID. To obtain your Identity Store ID, go to the AWS Identity Center console and select Settings. Under the Identity Source section, copy the Identity Store ID. In the same account used for AWS SSO, create the following parameter:

/ssosync/identity_store_id

2. Configure Google Cloud console

Within the Google Cloud console, we need to create a new Google Project and Service Account and enable the Admin SDK API. Follow these steps:

Open the Google Cloud console: https://console.cloud.google.com
Create a new project. Give the project a descriptive name such as AWS SSO Sync
Enable Admin SDK in APIs: APIs & Services > Enabled APIs & Services > + ENABLE APIS AND SERVICES

Enable Admin SDK # use raw URL so that this works in both GitHub and docusaurus

Create Service Account: IAM & Admin > Service Accounts > Create Service Account (ref).

Create Service Account # use raw URL so that this works in both GitHub and docusaurus

Download credentials for the new Service Account: IAM & Admin > Service Accounts > select Service Account > Keys > ADD KEY > Create new key > JSON

Download Credentials # use raw URL so that this works in both GitHub and docusaurus

Save the JSON credentials as a new SecureString AWS SSM parameter in the same account used for AWS SSO. Use the full JSON string as the value for the parameter.

/ssosync/google_credentials

3. Configure Google Admin console

Open the Google Admin console
From your domain’s Admin console, go to Main menu menu > Security > Access and data control > API controls (ref)
In the Domain wide delegation pane, select Manage Domain Wide Delegation.
Click Add new.
In the Client ID field, enter the client ID obtained from the service account creation steps above.
In the OAuth Scopes field, enter a comma-delimited list of the scopes required for your application. Use the scope https://www.googleapis.com/auth/cloud_search.query for search applications using the Query API.
Add the following permission: (ref)

https://www.googleapis.com/auth/admin.directory.group.readonly
https://www.googleapis.com/auth/admin.directory.group.member.readonly
https://www.googleapis.com/auth/admin.directory.user.readonly

4. Deploy the `aws-ssosync` component

Make sure that all four of the following SSM parameters exist in the target account and region:

/ssosync/scim_endpoint_url
/ssosync/scim_endpoint_access_token
/ssosync/identity_store_id
/ssosync/google_credentials

If deployed successfully, Groups and Users should be programmatically copied from the Google Workspace into AWS IAM Identity Center on the given schedule.

If these Groups are not showing up, check the CloudWatch logs for the new Lambda function and refer the FAQs included below.

5. Deploy the `aws-sso` component

Use the names of the Groups now provisioned programmatically in the aws-sso component catalog. Follow the aws-sso component documentation to deploy the aws-sso component.

FAQ

Why is the tool forked by `Benbentwo`?

The awslabs tool requires AWS Secrets Managers for the Google Credentials. However, we would prefer to use AWS SSM to store all credentials consistency and not require AWS Secrets Manager. Therefore we've created a Pull Request and will point to a fork until the PR is merged.

Ref:

What should I use for the Google Admin Email Address?

The Service Account created will assume the User given by --google-admin / SSOSYNC_GOOGLE_ADMIN / var.google_admin_email. Therefore, this user email must be a valid Google admin user in your organization.

This is not the same email as the Service Account.

If Google fails to query Groups, you may see the following error:

Notifying Lambda and mark this execution as Failure: googleapi: Error 404: Domain not found., notFound

Common Group Name Query Error

If filtering group names using query strings, make sure the provided string is valid. For example, google_group_match: "name:aws*" is incorrect. Instead use google_group_match: "Name:aws*"

If not, you may again see the same error message:

Notifying Lambda and mark this execution as Failure: googleapi: Error 404: Domain not found., notFound

Ref:

The specific error you are seeing is because the google api doesn't like the query string you provided for the -g parameter. try -g "Name:Fuel*"
