CDK For Terraform: MS Hosted Linux Build Agent

Greetings my fellow Technology Advocates and Specialists.

This is Chapter #4 of my Terraform CDK (Cloud Development Kit) Series.

In this Session, I will walk you through If CDK (Cloud Development Kit) for Terraform is available in Microsoft Hosted Linux Build Agent.

OBJECTIVES:-
# TOPICS
1. If Terraform is installed in Microsoft Hosted Linux Build Agent. If not, Pipeline will install and then validate.
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).
  4. Azure Resource Manager Service Connection in Azure DevOps.

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:-

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

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