Been banging my head on this for a few days now – i am sure its something obvious…. but i am missing it…

What i want to do is to pass a variable called publish defined in the pipeline definition UI into a template called echo.yml from the main pipeline.yml then in the template use the value of the variable as a condition on a task running or not.

So far no success.

Is this actually possible ?

Simplified example below, the real use case is to control whether or not a publish task executes.

echo.yml

parameters:
- name: 'desc'
  type: string
  default: none
- name: 'publish'
  type: string
  default: 'false'

steps:
- task: Bash@3
  condition: ${{ parameters.publish  }}
  inputs:
    targetType: 'inline'
    script: |
      echo desc is ${{ parameters.desc }}
      echo publish is ${{ parameters.publish }}

pipeline.yml

pool:
  vmImage: 'ubuntu-latest'

steps:
- task: Bash@3
  inputs:
    targetType: 'inline'
    script: |
      # Write your commands here
      echo SBN IS $(Build.SourceBranchName)
      echo SB IS $(Build.SourceBranch)

- template: echo.yml
  parameters:
    desc: 'my description'
    publish: ${{ variables.publish }}
