2.	If Node is installed in Microsoft Hosted Linux Build Agent.
3.	If Yarn is installed in Microsoft Hosted Linux Build Agent.
4.	If CDK for Terraform is installed in Microsoft Hosted Linux Build Agent. If not, Pipeline will install and then validate.

REQUIREMENTS:-

1. Azure Subscription.
2. Azure DevOps Organisation and Project.
3. Service Principal with Required RBAC ( Contributor) applied on Subscription or Resource Group(s).

So, here goes the answer:
"No, Terraform and CDK for Terraform DOES NOT come installed by default in Microsoft Hosted Linux Build Agent."

Now, let me explain each part of YAML Pipeline for better understanding.

PART #1:-

BELOW FOLLOWS PIPELINE VARIABLES CODE SNIPPET:-

######################
#DECLARE VARIABLES:-
######################
variables:
  ServiceConnection: amcloud-cicd-service-connection
  BuildAgent_Lin: ubuntu-latest
  envName: NonProd

NOTE:-
1. Please change the values of the variables accordingly.
2. The entire YAML pipeline is build using Variables. No Values are Hardcoded.

PART #2:-

This is a Single Stage Pipeline - TEST_CDK_FOR_TERRAFORM_ON_LINUX (with 1 Pipeline Task):-

stages:

- stage: TEST_CDK_FOR_TERRAFORM_ON_LINUX
  jobs:
  - job: TEST_CDK_FOR_TERRAFORM_ON_LINUX 
    displayName: TEST CDK FOR TERRAFORM ON LINUX
    steps:

PIPELINE TASK #1:-:-
1. Install and validate Terraform.
2. Validate Node.
3. Validate Yarn.
4. Install and validate CDK for Terraform.

          echo "The latest cdktf version installed is: $cdktf_validate_install"
          echo "##########################################################"

NOW ITS TIME TO TEST!!!

TEST CASES:-
1. Pipeline executed successfully.
2. Terraform Installed and Validated Successfully on MS Hosted Linux Build Agent.
3. Node and Yarn version validated Successfully on MS Hosted Linux Build Agent.
4. CDK for Terraform Installed and Validated Successfully on MS Hosted Linux Build Agent.

Hope You Enjoyed the Session!!!
