在模板中使用管道参数

Question

我在管道YAML文件和模板文件中都定义了参数。如何访问模板中在管道中定义的参数?？

管道文件

    parameters:
    - name: LIQUIBASE_DATABASE_URL
      displayName: JDBC Connection String
      type: string
      default: ''
    
    - name: LIQUIBASE_COMMAND_USERNAME
      displayName: Liquibase user name
      type: string
      default: ''
    
    - name: LIQUIBASE_COMMAND_PASSWORD
      displayName: Liquibase password
      type: string
      default: ''
    
    trigger: none
    
    stages:
      - stage: VersionUpgrade
        jobs:

模板文件

    # File Name : run-upgrade-template.yml
    
    parameters:
    - name: upgradeVersionList
      type: object
      default: [2,3,4]
    
    steps:
    - task: Bash@3
      inputs:
        targetType: 'inline'
        script: |
          echo "changeLogFile: $(Pipeline.Workspace)/database/db-changelog.sql" > liquibase.properties
          echo "url:  ${{ LIQUIBASE_DATABASE_URL }}"  >> liquibase.properties
          echo "username:  ${{ LIQUIBASE_COMMAND_USERNAME }}" >> liquibase.properties
          echo "password:  ${{ LIQUIBASE_COMMAND_PASSWORD }}" >> liquibase.properties
          cat liquibase.properties

我搞错了

pipeline-templates/run-upgrade-template.yml (Line: 12, Col: 13): Unrecognized value: 'LIQUIBASE_DATABASE_URL'. Located at position 264 within expression: format('echo "changeLogFile: $(Pipeline.Workspace)/database/db-changelog.sql" > liquibase.properties
echo "url:  {0}"  >> liquibase.properties
echo "username:  {1}" >> liquibase.properties
echo "password:  {2}" >> liquibase.properties
cat liquibase.properties
', LIQUIBASE_DATABASE_URL, LIQUIBASE_COMMAND_USERNAME, LIQUIBASE_COMMAND_PASSWORD).

感谢解决此问题的任何指示。

这里有很多问题。

1. 您的模板还需要定义这些参数的parameters块，这些参数需要传递给模板.

1. 您访问参数的语法不正确。${{ parameters.LIQUIBASE_COMMAND_USERNAME }}

应该是${{ LIQUIBASE_COMMAND_USERNAME }}
