This is a solution designed to automate installation & registration of Workspaces as SSM clients. It also adds Tags to the Managed instance (Workspace ID, Assigned User, Directory ID, Region, Hostname and OS along with the AD groups the user is assigned). The AD tags are Dynamic and change as Users AD group memberships change. These Tags can be used a way to create Target groups for SSM tasks such as Pachting, Package Deloyment and Run Command

With Automated Installation of SSM agent, you can use SSM tools such as Patch Managent, run Command, Automation and Distributor to Patch, deploy software and run compliance checks on your Workspace Fleet. You can also use SSM to Monitor managed node performance for troubleshooting purposes.

The Solution contain the following

• SAM Template that deploys the API Gateway and the Lambda Function
• Powershell Script that is deployed to the Workspace Image that automates SSM Agent download, install and configuration

Deploy Server Side Stack

• Clone the Repo to a machine that is configured to deploy resources in AWS.

• Setup AWS SAM CLI Make sure to follow the steps on installing Docker based on the OS of your choice as we use Docker images

• Build and deploy the SAM application

    sam build
    sam deploy --guided
  

• Provide the Parameters for Region, DNS IP of the AD server, Subnet and security groups for the Lambda function to be created.

• The Lambda script that adds Users AD groups as Tags to the Managed instance needs AD credentials to make LDAP calls. Create a AD user with rights to get users group membership. The template prompts to enter the AD Username.

• Save the AD password as a Secret of type 'Plaintext' in AWS Secrets Manager as explained here

• In the Stack output, you get the API Gateway endpoint thats needed for the Powershell script configuration.

Deploy Script on Workspace

The client side script is written in Powershell that works on both windows and Linux. Install Powershell 7 on a workspace before continuing.

Steps to install powershell on windows

Steps to install powershell on Amazon Linux

• Clone the Repo to the workspace that is going to have the script installed and be used for Imaging

• Open Powershell 7 command Prompt as Administrator

• Follow the steps below

    cd workspaces-ssm-install
    cd clientscripts
    ./createscript.ps1
  

The script prompts to enter the API endpoint URL that was created in the Previous step

• The script does the following based on the OS

  Windows

  • copies the script to C:\ProgramData\ssm_script
  • Creates a scheduled Task to run the script on startup and on schedule

  Linux

  • copies the script to /usr/local/bin
  • creates systemd service and timer
