• Exercise: Create an Azure DevOps Organization and create a project called as gameoflife and push the master branch of gameoflife from github into AzureSourceRepo

Writing Azure Pipelines in YAML

• YAML Tutorial Refer Here
• To write the Pipeline in YAML we need to understand the schema from Azure DevOps Refer Here
• Pipeline Schema Refer Here
• Triggers Refer Here
  • For periodic builds equivalent => Scheduled Trigger Refer Here
  • For poll scm equivalent => Push Trigger Refer Here
• Azure Pipleline job needs to run on some node. Azure DevOps uses the term agent to refer it. In Azure DevOps we have two types of agent
  • Microsoft Hosted Agents:
    • These are hosted by Azure/Microsoft
    • Free plan => 1800 minutes per month is free
  • Self Hosted Agents

• For all the tasks Refer Here

• The Azure pipeline which is created in the class

---
trigger:
  - master


variables:
  MVN_GOAL: 'package'

pool:
  name: Azure Pipelines
  vmImage: 'ubuntu-latest'

steps:
  - task: Maven@3
    inputs:
      mavenPomFile: 'pom.xml'
      goals: $(MVN_GOAL)
      jdkVersionOption: 1.8
      testResultsFiles: '**/surefire-reports/TEST-*.xml'

• Equivalent in Jenkins

pipeline {
  agent { label 'ubuntu' }
  triggers {
	pollSCM('* * * * *')
  }
  stages {
     stage('SCM') {
	steps {

		git 'htps:/lksdfskl'
	}
     }
     stage('build') {
	steps {
		sh 'mvn package'
		junit '**/surefire-reports/TEST-*.xml'
	}
     }
  }

}
