🚀 Quick Start

1. Import Pipeline Templates

# azure-pipelines.yml
resources:
  repositories:
    - repository: templates
      type: github
      name: SanjaySundarMurthy/azure-devops-pipelines
      ref: main

trigger:
  branches:
    include:
      - main
      - develop

stages:
  - template: templates/ci/build-dotnet.yml@templates
    parameters:
      projectName: 'MyMicroservice'
      dotnetVersion: '8.0'
      
  - template: templates/cd/deploy-aks.yml@templates
    parameters:
      environment: 'dev'
      aksCluster: 'aks-dev-cluster'

2. Configure Service Connections

Required Azure DevOps service connections:

• Azure Resource Manager (for AKS deployments)
• Docker Registry (for container images)
• SonarQube (for code quality)

🔧 Pipeline Templates
