Setup ACR Service Connection using Devops

Greetings to my fellow Technology Advocates and Specialists.

In this Session, I will demonstrate How to Automate Azure Container Registry (ACR) Service Connection using Devops.

AUTOMATION OBJECTIVES:-
# TOPICS
1. Install Azure Devops CLI Extension in the Build Agent.
2. Validate Azure Devops CLI Extension Installation by running the Help option in the Build Agent.
3. Download Key Vault Secrets.
4. Create Azure Container Registry Service Connection.
5. Grant Access Permission to Azure Container Registry Service Connection for all Pipelines.
IMPORTANT NOTE:-

The YAML Pipeline is tested on WINDOWS BUILD AGENT Only!!!

REQUIREMENTS:-
  1. Azure Subscription.
  2. Azure DevOps Organisation and Project.
  3. Full Access PAT (Personal Access Token).
  4. Service Principal with Required RBAC ( Contributor) applied on Subscription or Resource Group(s).
  5. Azure Resource Manager Service Connection in Azure DevOps.
  6. Azure Container Registry with "Admin" User Enabled.
  7. Key Vault with 3 Secrets stored - 1) Azure Container Registry password, 2) Azure DevOps Project ID, and 3) Azure Devops Personal Access Token (PAT).

NOW ITS TIME TO TEST!!!

TEST CASES:-
1. Pipeline executed successfully.
