Azure Pipeline Need to pass the power shell output to Kubernetes config map 似乎 Kubernetes 任务根本没有读取变量

Question

- task: PowerShell@2
    displayName: Save Storage account Secrets to Build Variables
    inputs:
      azureSubscription: 
      targetType: 'inline'
      script: '$outputs = ConvertFrom-Json $($env:STORAGE); foreach ($output in $outputs.PSObject.Properties) { echo $output.Name; echo $output.Value.value; Write-Host ("##vso[task.setvariable variable=$($output.Name);]$($output.Value.value)");}'

- phase: DEVRelease
  dependsOn: Build
  queue: Hosted Ubuntu 1604
  steps:
  - task: Kubernetes@1
    displayName: Apply Kubernetes Deployment
    inputs:
      kubernetesServiceEndpoint: 
      arguments: "-f conf/deploy_local.yaml"
      command: apply
      azureSubscription: 
      azureContainerRegistry: 
      configMapName: myconfig
      forceUpdateConfigMap: true
      configMapArguments: --from-literal=myname=$($env:STORAGEACCOUNTNAME1)

从不读取 $env:STORAGEACCOUNTNAME 变量

由于设置变量的 PowerShell 任务处于构建阶段。您需要在 setvariable 语句中添加 isOutput=true。请查看Set a multi-job output variable

"##vso[task.setvariable variable=$($output.name);isOutput=true]$($output.Value)"

我对您的 yaml 进行了一些更改以进行测试。请检查一下。我有环境变量STORAGE = {'tags':[{'name':'A', 'Value':'1' }, { 'name':'B', 'Value':'2'}]}

phases:
- phase: build
  queue: Hosted Ubuntu 1604
  steps:
  - powershell: |
      $outputs = ConvertFrom-Json $($env:STORAGE)
      foreach ($output in $outputs.tags) { echo $output.name; echo $output.Value; Write-Host ("##vso[task.setvariable variable=$($output.name);isOutput=true]$($output.Value)");}
    name: myvariables
  - powershell: |
      echo "$(myvariables.A)"
      echo "$(myvariables.A)"


- phase: DEVRelease
  dependsOn: Build
  queue: Hosted Ubuntu 1604
  variables: 
    Da: $[ dependencies.build.outputs['myvariables.A'] ]
    Db: $[ dependencies.build.outputs['myvariables.B'] ]

  steps:
  - powershell: |
      echo $(Da)
      echo $(Db)

在上面的脚本中，我通过在语句中添加isOutput=true 在阶段构建中输出变量，并将我的powershell 任务命名为name: myvariables。

我在下一阶段 DEVRelease 中使用语句 $[ dependencies.{dependent phase name}.outputs['{task name}.{variable name}'] ] 引用输出变量并将其分配给 Variables。

然后我可以在阶段 DEVRelease 中成功获取 powershell 任务中的值。
