json - CI 管道失败，即使它正在做它应该做的事情

Question

首先我要说的是，我刚刚开始使用 Azure，绝不是专业人士，并且一直在遵循各种指南。所以，我正在关注this文章通过部署this在我自己的 Azure DevOps 订阅中存储库，在更改资源组、订阅和函数名称后，我构建并运行 CI 管道，然后在“部署 Azure 资源”处我会得到 this即使在管道退出后，资源按照预期的方式创建，我也注意到如果我第二次重新运行相同的管道，它会完美地工作，这令人困惑。这是我修改后的 YAML 模板

name: DeployAzureFunction
variables:
  FunctionAppName: 'test'
  AzureConnection: 'DevOps-Test'
  ResourcegGroupName: 'test'

trigger:
  branches:
    include:
    - '*'  # must quote since "*" is a YAML reserved character; we want a string



stages:

- stage: Build
  jobs:
  - job: Test_FA
    pool:
      vmImage: windows-2019
    steps:
    - task: AzureResourceGroupDeployment@2
      displayName: 'Test ARM Deployment'
      inputs:
        azureSubscription: $(AzureConnection)
        resourceGroupName: $(ResourcegGroupName)
        location: 'East US 2'
        csmFile: Deployment/azuredeploy.json
        deploymentMode: Validation
    - powershell: |
       Install-PackageProvider -Name NuGet -Force -Scope CurrentUser
       Install-Module -Name Pester -Force -Scope CurrentUser -SkipPublisherCheck
       Install-Module -Name PSScriptAnalyzer -Force -Scope CurrentUser
      displayName: 'Install Pester and import module'
   
  - job: Build_FA
    pool:
      vmImage: windows-2019
    steps:
    - task: ArchiveFiles@2
      displayName: 'Archive FunctionApp'
      inputs:
        rootFolderOrFile: FunctionApp
        includeRootFolder: false
        archiveFile: '$(System.DefaultWorkingDirectory)/zip/FunctionApp.zip'
    - task: PublishPipelineArtifact@0
      inputs:
        artifactName: 'zip'
        targetPath: '$(System.DefaultWorkingDirectory)/zip'

- stage: Deploy
  jobs:
  - job: Deploy_ARM
    pool:
      vmImage: windows-2019
    steps:
    - task: AzureResourceGroupDeployment@2
      displayName: 'Deploy Azure Resources'
      continueOnError: true
      inputs:
        azureSubscription: $(AzureConnection)
        resourceGroupName: $(ResourcegGroupName)
        location: 'East US 2'
        csmFile: Deployment/azuredeploy.json
        csmParametersFile: Deployment/azuredeploy.parameters.json
        overrideParameters: '-functionAppName $(FunctionAppName)'
        deploymentMode: Incremental
        deploymentOutputs: DeploymentOutput

这是未修改的 azuredeploy.json，我认为它导致了问题，但不确定原因

        }
    }
}

如果有人能帮我弄清楚为什么我在第一次运行时会遇到该错误，我将不胜感激，谢谢!

资源已创建，但部署操作失败，因为计算输出变量时出现问题。

很可能是由于您尝试访问应用服务的服务主体 ID 的方式所致。 “/providers/Microsoft.ManagedIdentity/Identities/default”部分。

你可能想要这样的东西:

[reference(resourceId('Microsoft.Web/sites', parameters('functionAppName')), '2016-08-01', 'Full').identity.principalId]
