Access YAML variable in inline PowerShell script

Question

If I have a YAML Pipeline;

variables:
- name  : myVariable
  value : 'abcd'

and if I want to run some inline powershell - how can i access that value (abcd) in the powershell script;

I expected this to work - but it didnt;

- task: PowerShell@2
    displayName: "Do the thing"
    inputs:
      targetType: 'inline'
      script: 
        write-host $(myVariable)

Answer 1

we could refer to this doc to specify variables at the pipeline, stage, or job level.

YAML build definition:

pool:
  vmImage: 'vs2017-win2016'

variables:
- name  : myVariable
  value : 'abcd'

steps:

- task: PowerShell@2
  displayName: "Do the thing"
  inputs:
    targetType: 'inline'
    script: 
      write-host $(myVariable)

Result:
