您可以将变量组值传递到Yaml中的子模板吗? [英] Can you pass Variable Group values to sub template in yaml?

问题描述

我正在尝试创建一个多阶段管道，该管道具有为管道的每个阶段定义的变量组.目标是将组中的值作为参数传递给子模板.似乎在该阶段定义的Group的价值没有传递到子模板中.它覆盖了"DEFAULTVALUE".带有空字符串.

I'm trying to create a multi-stage pipeline which has Variable Groups defined for each stage of the pipeline. The goal is to pass values from the group as parameters to a sub template. It seems the value of the Group, defined at the stage, is not getting passed in to the sub template. It overrides the "DEFAULTVALUE" with an empty string.

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)'

sub-template.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)'

我也尝试过在子模板中添加变量组，但这也无法正确解析...

I have also tried adding the variable group within the sub-template but that also doesn't parse correctly...

有人知道这是否可能吗?

Does anyone know if this is possible?

推荐答案

一个已知的问题是，不能在阶段级别下定义的变量组中引用服务连接终结点.

It is a known issue that the service connection endpoint cannot be referenced in variable groups defined under stage level.

您可以通过以下解决方法解决此问题:

You can fix this issue by below workarounds:

1，在全局级别而不是阶段级别中定义变量组，如下所示:

1, Define the variable groups in the global level instead of stage level See below:

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页面上链接变量组.

2, Link the variable groups on the UI page.

在yaml管道编辑页面上->点击3点->触发器->变量选项卡->链接变量组

On the yaml pipeline edit page--> Click the 3dots-->Triggers-->Variables Tab-->Link Variable group
