Question

In AzureDevops, trying to run a yaml file to trigger a powershell script - how can i assign different environment values to script so that it runs for all environment.

parameters:
  - name: environmentName
    type: string
    default: 'PROD'
  - name: azureSubscription
    type: string
    default: 'ABC-Prod'
    
  - job: ABC
    variables:
      - group: 'ABC-${{ parameters.environmentName }}'
        
    steps:
      - task: AzurePowerShell@5 
        inputs:
          #azureSubscription: 'ABC-nonprod-dev'
          scriptType: 'FilePath'
          azurePowerShellVersion: 'LatestVersion'
          scriptPath: 'src/databricks/ABC.ps1'
        displayName: 'ABC Databrick Job'

Now this job needs to be run in DEV, UAT and PROD and azureSubscription - 'ABC-nonprod-dev','ABC-nonprod-uat' and 'ABC-prod'

How we can run a loop in powershell so that ABC.ps1 script can run for all 3 environments

Answer 1

To create foreach you can use expressions combined with 'each' keyword providing list of environments as a object

parameters:
- name: environments
  type: object
  default:
  - dev
  - prod

steps:     
- ${{ each value in parameters.environments}}:
  - script: echo ${{ value }}
