PIPELINE STAGE DETAILS FOLLOW BELOW:-
This is a 3 Stage Pipeline with 2 Runtime Variables - 1) DevOps Environment, and 2) Action To Perform
The Names of the Stages are - 1) PUBLISH_PLAN 2) BUILD, and 3) DEPLOY

PUBLISH_PLAN STAGE PERFORMS BELOW:-
## TASKS
1.
Terraform Installer installed in Azure DevOps Build Agent.
2.

3.
Terraform Validate
4.
Terraform Plan
5.
Publish Terraform Plan in Azure DevOps GUI.

Exit fullscreen mode
EXPLANATION:-
Instead of using TerraformInstaller@0 YAML Task, I have specified the Full Name. This is because I have two Terraform Extensions in my DevOps Organisation and with each of the Terraform Extension, exists the Terraform Install Task
The Names of the Extensions are listed below:-
1. Terraform by Microsoft DevLabs
2. Azure Pipelines Terraform Tasks by Charles Zipp
If Full Name is not provided , then below Error is Encountered :-
Alternatively , below can also be used as Full Name:-

PIPELINE STAGE BUILD EXECUTED SUCCESSFULLY:-
PIPELINE STAGE DEPLOY WAITING APPROVAL:-
PIPELINE STAGE DEPLOY EXECUTED SUCCESSFULLY:-
PIPELINE OVERALL EXECUTION STATUS:-
VALIDATE RESOURCES DEPLOYED IN PORTAL:-
IMPORTANT TO NOTE:-
Terraform Plan are NOT PUBLISHED in Azure DevOps GUI unless there is a change in Infrastructure - ADD , DESTROY or CHANGE
In order to demonstrate, the same pipeline was re-run.
