Basic docker pipeline

• Basic Pipeline

pool: default
trigger: 
  - master
stages:
  - stage: buildstage
    displayName: Build the application
    jobs:
      - job: dockerbuild
        displayName: docker image build
        pool: default
        steps:
          - task: Docker@2

              repository: shaikkhajaibrahim/nopfromado
              command: 'buildAndPush'
              Dockerfile: "$(dockerfilelocation)"
              tags: "$(Build.BuildId)"

Templates

• Refer Here for templates documentation

lets create a resuable template for java based application

• Create a new folder called as templates with a file maven-template.yaml with following content

steps:
  - task: Maven@4
    inputs:
      mavenPOMFile: pom.xml
      goals: package
      publishJUnitResults: true
      testResultsFiles: '**/TEST-*.xml'
      javaHomeOption: Path
      jdkVersionOption: '1.17'
      jdkDirectory: '/usr/lib/jvm/java-17-openjdk-amd64'
      mavenVersionOption: Path
      mavenDirectory: '/usr/share/maven'

• Now add the following in azure-pipelines.yaml

pool: default

trigger: 
  - main

steps:
  - template: templates/maven-template.yaml

• Now lets build the pipeline
• Lets create template parameters

parameters:
  - name: mavenPomfile
    displayName: pom location 
    type: string
    default: pom.xml
  - name: goals
    displayName: maven goal
    type: string
    default: package
    values:
      - clean
      - compile
      - test
      - package
      - install
      - deploy
  - name: publishJUnitResults
    displayName: pom location 
    type: boolean
    default: true


steps:
  - task: Maven@4
    inputs:
      mavenPOMFile: "${{ parameters.mavenPomfile }}"
      goals: "${{ parameters.goals }}"
      publishJUnitResults: "${{ parameters.publishJUnitResults }}"
      testResultsFiles: '**/TEST-*.xml'
      javaHomeOption: Path
      jdkVersionOption: '1.17'
      jdkDirectory: '/usr/lib/jvm/java-17-openjdk-amd64'
      mavenVersionOption: Path
      mavenDirectory: '/usr/share/maven'

• in azure-devops pipeline call template with parameters values

pool: default

trigger: 
  - main

steps:
  - template: templates/maven-template.yaml
    parameters:
      goals: 'test'

• We have create a stages template
  

Lets create an azure repo with reusable templates

• We have create a git repo of ADO templates
  
• refer the below yaml for usage

---
trigger:
  - master

resources:
  repositories:
    - repository: templates
      name: ADOTemplates
      type: git
      ref: main



stages:
  - template: docker/docker-template.yaml@templates
    parameters:
      containerRegistry: 'mydockerhub'
      vmImage: 'ubuntu-22.04'

Activity

• Create a pipeline for building a node js application
• softwares:
  • git
  • nodejs (20.9.0)
  • npm
