我可以用一个值列表实例化一个模板管道吗？

Question

我们有以下Azure DevOps管道模板：

- stage: DeployToPreprod
  displayName: 'Deploy to PREPROD'
  dependsOn: PrepareDeployToPreprod
  condition: not(eq(variables['Build.Reason'], 'Schedule'))
  jobs:
    - template: Scripts/deploy.yaml
      parameters:
        targetHost: SRV-SAF
        targetHostDisplayName: SRV_SAF
        targetEnv: PREPROD
    - template: Scripts/deploy.yaml
      parameters:
        targetHost: DT1CTX003
        targetHostDisplayName: DT1CTX003
        targetEnv: PREPROD
    - template: Scripts/deploy.yaml
      parameters:
        targetHost: DT1CTX004
        targetHostDisplayName: DT1CTX004
        targetEnv: PREPROD
    - template: Scripts/deploy.yaml
      parameters:
        targetHost: VDA-PROD-R01
        targetHostDisplayName: VDA_PROD_R01
        targetEnv: PREPROD
    - template: Scripts/deploy.yaml
      parameters:
        targetHost: VDA-PROD-R02
        targetHostDisplayName: VDA_PROD_R02
        targetEnv: PREPROD
    - template: Scripts/deploy.yaml
      parameters:
        targetHost: VDA-PROD-R03
        targetHostDisplayName: VDA_PROD_R03
        targetEnv: PREPROD
    - template: Scripts/deploy.yaml
      parameters:
        targetHost: VDA-PROD-R04
        targetHostDisplayName: VDA_PROD_R04
        targetEnv: PREPROD

可以很容易地看到，这基本上是用一个不同机器名称的列表实例化相同的模板。是否有一种方法可以删除一些重复，并多次实例化模板，给它一个列表？

是否有一种方法可以删除一些重复，并多次实例化模板，给它一个列表？

答案是肯定的。

您可以使用策略与矩阵来解决这个问题：

- stage: DeployToPreprod
  displayName: 'Deploy to PREPROD'
  dependsOn: PrepareDeployToPreprod
  condition: not(eq(variables['Build.Reason'], 'Schedule'))
  jobs:
  - job: Dev
    displayName: Dev
    pool:
     name: MyPrivateAgent

    strategy: 
      matrix:
        dev_1:
          targetHost: SRV-SAF
          targetHostDisplayName: SRV_SAF
          targetEnv: PREPROD
        dev_2:
          targetHost: DT1CTX003
          targetHostDisplayName: DT1CTX003
          targetEnv: PREPROD

     - template: child.yml #change this to your Scripts/deploy.yaml file
       parameters:
         targetHost: $(targetHost)
         targetHostDisplayName: $(targetHostDisplayName)
         targetEnv: $(targetEnv)

The Child.yml

parameters:
- name: targetHost 
  type: string 
  default: false

- name: targetHostDisplayName 
  type: string 
  default: false

- name: targetEnv 
  type: string 
  default: false

steps:
- script: echo ${{ parameters.targetHost }}
  displayName: 'targetHost'

- script: echo ${{ parameters.targetHostDisplayName }}
  displayName: 'targetHostDisplayName'

- script: echo ${{ parameters.targetEnv }}
  displayName: 'targetEnv'

结果：

希望这能有所帮助。
