如何在 Azure DevOps 中使用具有阶段依赖性的 DependsOn答案

【问题标题】：How to work with DependsOn having stage dependency in Azure DevOps如何在 Azure DevOps 中使用具有阶段依赖性的 DependsOn
【发布时间】：2021-02-20 01:01:04
【问题描述】：

我有以下进行多阶段部署的模板：

parameters:
- name: Stage
  type: string
- name: Environment
  type: string
- name: Enabled  
  type: boolean
  default: false
- name: WebAppName
  type: string
- name: ArtifactName
  type: string

stages:

- stage: ${{ parameters.Stage }}  
  displayName: '${{ parameters.Stage }} Stage'
  dependsOn: '${{ parameters.DependsOn }}'
  jobs:
   - deployment: ${{ parameters.Environment }} 
     timeoutInMinutes: 70
     environment: '${{ parameters.Environment }} Environment'
     pool:
        vmImage: $(vmImageName)
     strategy:
      runOnce:
        deploy:
          steps:
          - task: DownloadBuildArtifacts@0
            inputs:
              buildType: 'current'
              downloadType: 'single'
              artifactName: ${{ parameters.ArtifactName }}
              downloadPath: '$(System.ArtifactsDirectory)'
          - task: AzureRmWebAppDeployment@4
            inputs:
              ConnectionType: 'AzureRM'
              azureSubscription: 'AzureConnectionSC'
              appType: 'webApp'
              WebAppName: ${{ parameters.WebAppName }}
              package: '$(System.ArtifactsDirectory)/**/*.zip'

从我的管道中，我正在使用模板：

- template: azure-pipelines-multi-stage-release.yml  # Template reference
    parameters:
       Environment: 'Dev'
       Enabled: True
       WebAppName: 'azureappservicehelloworldapp-dev'
       Stage: 'Dev'
       ArtifactName : 'helloWorldArtifact'

  - template: azure-pipelines-multi-stage-release.yml  # Template reference
    parameters:
       Environment: 'UAT'
       Enabled: True
       WebAppName: 'azureappservicehelloworld-uat'
       Stage: 'UAT'
       ArtifactName : 'helloWorldArtifact'

  - template: azure-pipelines-multi-stage-release.yml  # Template reference
    parameters:
       Environment: 'Prod'
       Enabled: True
       WebAppName: 'azureappservicehelloworld'
       Stage: 'Prod'
       ArtifactName : 'helloWorldArtifact'

如何将 DependsOn 传递到模板中，在 dev 中没有阶段依赖，因此它应该直接部署，但 UAT 依赖于 Dev，Prod 依赖于 UAT。如何将值传递给模板，如果没有传递任何内容，它应该继续部署，如果某些内容作为依赖项传递，它应该在安装之前验证该阶段。

你检查过以下回复吗？你的问题解决了吗？
嗨 Cece Don，以下答案有所帮助，但它仍在继续下一步，无需等待依赖，我在环境管道下找到了一个解决方案，点击环境有一个名为批准和检查的设置我们可以在那里添加而不是依赖于.. 我会支持答案谢谢

【解决方案1】：

您在模板中声明了一个DependsOn 对象参数。这将是必需的，但在模板中进行了检查。如果您不想要依赖项，只需传递一个空的 DependsOn。这被设置为一个对象，以便您可以传递阶段列表，以防您有一个依赖于多个阶段的阶段。

这样设置你的管道：

stages:
- template: azure-pipelines-multi-stage-release.yml  # Template reference
  parameters:
      Environment: 'Dev'
      Enabled: True
      WebAppName: 'azureappservicehelloworldapp-dev'
      Stage: Dev
      ArtifactName : 'helloWorldArtifact'
      # empty DependsOn, as Dev depends on nothing
      DependsOn:
- template: azure-pipelines-multi-stage-release.yml  # Template reference
  parameters:
      Environment: 'UAT'
      Enabled: True
      WebAppName: 'azureappservicehelloworld-uat'
      Stage: UAT
      ArtifactName : 'helloWorldArtifact'
      DependsOn:
      - Dev
- template: azure-pipelines-multi-stage-release.yml  # Template reference
  parameters:
      Environment: 'Prod'
      Enabled: True
      WebAppName: 'azureappservicehelloworld'
      Stage: Prod
      ArtifactName : 'helloWorldArtifact'
      DependsOn:
      - UAT

你的模板是这样的：

parameters:
- name: Stage
  type: string
- name: Environment
  type: string
- name: Enabled  
  type: boolean
  default: false
- name: WebAppName
  type: string
- name: ArtifactName
  type: string
- name: DependsOn
  type: object

stages:
- stage: ${{ parameters.Stage }}  
  displayName: '${{ parameters.Stage }} Stage'
  # only include the DependsOn parameter if provided
  ${{ if parameters.DependsOn }}:
    dependsOn: '${{ parameters.DependsOn }}'
  jobs:
   - deployment: ${{ parameters.Environment }} 
     timeoutInMinutes: 70
     environment: '${{ parameters.Environment }} Environment'
     pool:
        vmImage: $(vmImageName)
     strategy:
      runOnce:
        deploy:
          steps:
          - task: DownloadBuildArtifacts@0
            inputs:
              buildType: 'current'
              downloadType: 'single'
              artifactName: ${{ parameters.ArtifactName }}
              downloadPath: '$(System.ArtifactsDirectory)'
          - task: AzureRmWebAppDeployment@4
            inputs:
              ConnectionType: 'AzureRM'
              azureSubscription: 'AzureConnectionSC'
              appType: 'webApp'
              WebAppName: ${{ parameters.WebAppName }}
              package: '$(System.ArtifactsDirectory)/**/*.zip'

您的管道将扩展到：

stages:
- stage: Dev
  displayName: Dev Stage
  jobs:
  - deployment: Dev
    timeoutInMinutes: 70
    environment:
      name: Dev Environment
    pool:
      vmImage: $(vmImageName)
    strategy:
      runOnce:
        deploy:
          steps:
          - task: DownloadBuildArtifacts@0
            inputs:
              buildType: 'current'
              downloadType: 'single'
              artifactName: helloWorldArtifact
              downloadPath: '$(System.ArtifactsDirectory)'
          - task: AzureRmWebAppDeployment@4
            inputs:
              ConnectionType: 'AzureRM'
              azureSubscription: 'AzureConnectionSC'
              appType: 'webApp'
              WebAppName: azureappservicehelloworldapp-dev
              package: '$(System.ArtifactsDirectory)/**/*.zip'
- stage: UAT
  displayName: UAT Stage
  dependsOn:
  - Dev
  jobs:
  - deployment: UAT
    timeoutInMinutes: 70
    environment:
      name: UAT Environment
    pool:
      vmImage: $(vmImageName)
    strategy:
      runOnce:
        deploy:
          steps:
          - task: DownloadBuildArtifacts@0
            inputs:
              buildType: 'current'
              downloadType: 'single'
              artifactName: helloWorldArtifact
              downloadPath: '$(System.ArtifactsDirectory)'
          - task: AzureRmWebAppDeployment@4
            inputs:
              ConnectionType: 'AzureRM'
              azureSubscription: 'AzureConnectionSC'
              appType: 'webApp'
              WebAppName: azureappservicehelloworld-uat
              package: '$(System.ArtifactsDirectory)/**/*.zip'
- stage: Prod
  displayName: Prod Stage
  dependsOn:
  - UAT
  jobs:
  - deployment: Prod
    timeoutInMinutes: 70
    environment:
      name: Prod Environment
    pool:
      vmImage: $(vmImageName)
    strategy:
      runOnce:
        deploy:
          steps:
          - task: DownloadBuildArtifacts@0
            inputs:
              buildType: 'current'
              downloadType: 'single'
              artifactName: helloWorldArtifact
              downloadPath: '$(System.ArtifactsDirectory)'
          - task: AzureRmWebAppDeployment@4
            inputs:
              ConnectionType: 'AzureRM'
              azureSubscription: 'AzureConnectionSC'
              appType: 'webApp'
              WebAppName: azureappservicehelloworld
              package: '$(System.ArtifactsDirectory)/**/*.zip'

【解决方案2】：

您可以使用dependsOn 块的条件插入：

${{ if ne(parameters.DependsOn, '')}}:
  dependsOn: ${{ parameters.DependsOn }}

您显然还必须为您的模板声明一个DependsOn 参数。
