在Azure DevOps管道中将对象传递到模板

Question

我是一名有用的翻译助手。需要翻译的内容与IT技术相关。以下是您需要翻译的文本：

我正在尝试重构在大约100个帐户上运行的Azure DevOps作业，目前这些作业是管道中几乎相同的个别任务。它们偶然会调用AWS中的一些Cloud Formation，但这并不重要。

我想在管道中设置一个模板参数，例如：

parameters:
- name: stackparams
  type: object
  default:
    - displayname: AWS Test User Account
      awscredentials: TESTAWS-appaccounttest1-AzureDevOps
      templatefile: ./Test/TestApp/SwitchRolesGroupsPolicies.yml
      templateparametersfile: ./Test/LZTestApp/demoparams.json
    - displayname: Second Account
      awscredentials: TESTAWS-appaccounttest2-AzureDevOps
      templatefile: ./Test/Something/SwitchRolesGroupsPolicies.yml
      templateparametersfile: ./Test/Something/demoparams.json

在模板中，类似以下内容：-

parameters:
- name: stackparams
  type: object

steps:
- ${{ each stackparam in parameters.stackparams }}:
  - checkout: self
  - task: AWSShellScript@1
    inputs:
      awsCredentials: ${{ stackparams.awscredentials }}
      regionName: 'eu-west-1' 
      scriptType: 'inline'
      inlineScript: |
        echo "\$STACKPARAMS_DISPLAYNAME: $STACKPARAMS_DISPLAYNAME"
    displayName: 'This is a test - ${{ stackparams.displayname }}'

然而，我不知道这是否可能，并且关于以这种方式进行操作的文档非常少。目前，我已经将Cloud Formation暂时替换为AWSShellScript，仅仅是为了证明概念的可行性。我目前遇到的错误是：

是可以的。您已经接近成功了。您的模板中有一个小错误。${{ stackparams.awscredentials }}应为${{ stackparam.awscredentials }}。

如果您正在使用相同的源代码库，则循环中不需要包含- checkout: self。因为任务在同一个作业中运行，所以源代码库只需检出一次。请参见以下完整示例：

#azure-pipeline.yaml

parameters:
- name: stackparams
  type: object
  default:
    - displayname: AWS Test User Account
      awscredentials: TESTAWS-appaccounttest1-AzureDevOps
      templatefile: ./Test/TestApp/SwitchRolesGroupsPolicies.yml
      templateparametersfile: ./Test/LZTestApp/demoparams.json
    - displayname: Second Account
      awscredentials: TESTAWS-appaccounttest2-AzureDevOps
      templatefile: ./Test/Something/SwitchRolesGroupsPolicies.yml
      templateparametersfile: ./Test/Something/demoparams.json

trigger: none
pool: 
  vmImage: windows-latest

steps:
- template: stepsTemplate.yml
  parameters:
    stackparams: ${{parameters.stackparams}}  #pass the parameters to template parameters

--

#stepsTemplate.yml

parameters:
- name: stackparams
  type: object

steps:
- ${{ each stackparam in parameters.stackparams }}:
  
  - task: AWSShellScript@1
    inputs:
      awsCredentials: ${{ stackparam.awscredentials }}
      regionName: 'eu-west-1' 
      scriptType: 'inline'
      inlineScript: |
        echo "\$STACKPARAMS_DISPLAYNAME: $STACKPARAMS_DISPLAYNAME"
    displayName: 'This is a test - ${{ stackparam.displayname }}'

谢谢，那个是个愚蠢的错误（就像所有的错误一样，直到你知道答案才明白）。 - Steve Button

我使用参数stackparams传递了-name和默认值。这样不起作用。谢谢你的示例！ - Martin Dekker
