azure - 您可以将变量组值传递给 yaml 中的子模板吗？

Question

我正在尝试创建一个多级管道，其中为管道的每个阶段定义了变量组。目标是将组中的值作为参数传递给子模板。看来在该阶段定义的组的值没有传递到子模板中。它用空字符串覆盖“DEFAULTVALUE”。

pipeline.yml

trigger:
- none

pool:
  name: 'Azure Pipelines'
  vmImage: windows-latest

stages:
  - stage: DEV
    variables:
      - group: my-group-dev
    jobs:
      - template: sub-template.yml
        parameters:
          env: 'dev'
          subscriptionName: '$(SubscriptionName)' # This reference from the variable group doesn't get passed in
          subscriptionId: '$(SubscriptionId)'

  - stage: TEST
    variables:
      - group: my-group-test
    jobs:
      - template: sub-template.yml
        parameters:
          env: 'test'
          subscriptionName: '$(SubscriptionName)' # This reference from the variable group doesn't get passed in
          subscriptionId: '$(SubscriptionId)'

子模板.yml

parameters:
  env: 'DEFAULTVALUE'
  subscriptionName: 'DEFAULTVALUE'
  subscriptionId: 'DEFAULTVALUE'

jobs:
  - deployment: ResourceDeployment
    displayName: Deploy Resources ${{ parameters.env }}
    environment: ${{ parameters.env }}
    strategy:
      runOnce:
        deploy:
          steps:
            - task: AzureFileCopy@4
              displayName: 'Upload ARM Templates'
              inputs:
                sourcePath: '$(Pipeline.Workspace)/templates'
                azureSubscription: '${{ parameters.subscriptionName }}'
                destination: 'azureBlob'
                storage: 'my-storage-account'
                containerName: 'arm'
              name: AzureFileCopy

            - task: AzureResourceManagerTemplateDeployment@3
              inputs:
                deploymentScope: 'Resource Group'
                azureResourceManagerConnection: '${{ parameters.subscriptionName }}'
                subscriptionId: '${{ parameters.subscriptionId }}'
                action: 'Create Or Update Resource Group'
                resourceGroupName: 'my-resource-group'
                location: 'eastus2'
                templateLocation: 'URL of the file'
                csmFileLink: '$(AzureFileCopy.StorageContainerUri)${{ parameters.env }}/templates/main.json$(AzureFileCopy.StorageContainerSasToken)'

我还尝试在子模板中添加变量组，但这也无法正确解析...

有人知道这是否可行吗？

已知问题是无法在阶段级别定义的变量组中引用服务连接端点。

您可以通过以下解决方法解决此问题:

1、在全局级别定义变量组，而不是阶段级别 见下文:

trigger:
- none

pool:
  name: 'Azure Pipelines'
  vmImage: windows-latest

# define the variable group under global level.

variables:
- group: my-group-dev
- group: my-group-test


stages:
  - stage: DEV
    jobs:
      - template: sub-template.yml
        parameters:
          env: 'dev'
          subscriptionName: '$(SubscriptionName)' # This reference from the variable group doesn't get passed in
          subscriptionId: '$(SubscriptionId)'

  - stage: TEST
    jobs:
      - template: sub-template.yml
        parameters:
          env: 'test'
          subscriptionName: '$(SubscriptionName)' # This reference from the variable group doesn't get passed in
          subscriptionId: '$(SubscriptionId)'

2、在UI页面链接变量组。

在yaml管道编辑页面-->点击3dots-->触发器-->变量选项卡-->链接变量组
