Azure Pipelines

• Azure Pipelines are written in YAML Format.
• YAML is a data representation format with key value (name value) pairs as it basic structure.
• The tool will define th structure
  • Azure DevOps
  • K8s
  • Compose
• YAML represents data in name value

Understanding Azure DevOps Pipeline Concepts

• pipeline structure (First Version)
  
• An Agent i.e. a machine to build can be chosen at
  • Pipeline
  • Stage
  • Job
    
• To Simplify the pipeline
  • If your pipeline has one stage and muliple jobs, then represent pipeline has set of jobs
  • If your pipeline has one stage, one job and multiple steps, then represent pipeline as set of steps

Lets create our first dummy pipeline

• Lets create a pipeline which runs on microsoft hosted agent which will have Windows OS
• It will have 3 stages
  • Build
    • It will have 1 jobs
      • build the code
  • System Test
    • It will have 1 job which starts the selenium tests
  • Deploy
    • It will have 1 job which runs the terraform
• Pool defines the agents. Check for agent names
• This is dummy as it will only print the value but not execute

---
name: dummy
pool: windows-2022
stages:
- stage: build
  jobs:
  - job: build
    steps:
    - script: echo Building
- stage: test
  jobs:
  - job: test
    steps:
    - script: echo testing
- stage: deploy
  jobs:
  - job: deploy
    steps:
    - script: echo deploying

• I have one stage, one job and 3 steps

---
name: dummy
pool: ubuntu-latest
steps:
- script: echo step1
- script: echo step2
- script: echo step3

• Pipeline generated in last session

trigger:
- main

pool:
  vmImage: ubuntu-latest

steps:
- task: Maven@3

    mavenPomFile: 'pom.xml'
    mavenOptions: '-Xmx3072m'
