如何将Azure管道变量传递到AzureResourceManagerTemplateDeployment @ 3任务使用的ARM模板？

我正在尝试在计划每晚执行的Azure管道中执行以下2个步骤：

  1. 将自签名证书放入密钥库
  2. 通过ARM模板部署Service Fabric集群，并使用证书指纹和秘密ID作为参数。

在密钥库中创建证书的第一步对我来说很有效：

# import the self-signed certificate ccg-self-signed-cert into the Keyvault
- task: AzurePowerShell@5
  inputs:
    azureSubscription: '${{ parameters.ArmConnection }}'
    ScriptType: 'InlineScript'
    azurePowerShellVersion: '3.1.0'
    Inline: |
      $Pwd = ConvertTo-SecureString -String 'MyPassword' -Force -AsPlainText
      $Base64 = 'MIIKqQ____3000_CHARS_HERE______1ICAgfQ=='
      $Cert = Import-AzKeyVaultCertificate -VaultName $(KeyVaultName) -Name my-self-signed-cert -CertificateString $Base64 -Password $Pwd
      echo "##vso[task.setvariable variable=Thumbprint;isOutput=true]$Cert.Thumbprint"

我想我在echo行设置了管道变量（不太确定，如何验证...）

但是如何在下一个管道任务中将具有cert指纹值的管道变量传递给ARM模板？

# deploy SF cluster by ARM template and use the SF Cluster certificate thumbsprint as admin cert
- task: AzureResourceManagerTemplateDeployment@3
  inputs:
    deploymentScope: 'Resource Group'
    azureResourceManagerConnection: '${{ parameters.ArmConnection }}'
    subscriptionId: 'XXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXX'
    action: 'Create Or Update Resource Group'
    resourceGroupName: '${{ parameters.resourceGroupName }}'
    location: 'West Europe'
    templateLocation: 'Linked artifact'
    csmFile: '$(Build.SourcesDirectory)/pipelines/templates/sfcluster.json'
    csmParametersFile: '$(Build.SourcesDirectory)/pipelines/templates/sfcluster-params.json'
    deploymentMode: 'Incremental'

我正在使用azure-quickstart-template创建SF集群。

如果您查看它，它期望将证书指纹作为参数：

"certificateThumbprint": {
  "type": "string",
  "metadata": {
    "description": "Certificate Thumbprint"
  }
},

"certificateUrlValue": {
  "type": "string",
  "metadata": {
    "description": "Refers to the location URL in your key vault where the certificate was uploaded, it is should be in the format of https://<name of the vault>.vault.azure.net:443/secrets/<exact location>"
  }
},

如何将值从AzurePowerShell @ 5任务传递到后续AzureResourceManagerTemplateDeployment @ 3任务使用的ARM模板？

更新：

我尝试遵循Nilay的建议，并将3个变量放入我的sfcluster.json ARM模板中：

{
    "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
    "contentVersion": "1.0.0.0",
    "parameters": {
        "clusterName": {
            "type": "string",
            "defaultValue": "ccg-sfcluster",
            "minLength": 5,
            "metadata": {
                "description": "Name of the SF cluster"
            }
        },
        "certificateThumbprint": {
            "type": "string",
            "defaultValue": "[$env:THUMBPRINT]",
            "metadata": {
                "description": "Certificate Thumbprint"
            }
        },
        "sourceVaultResourceId": {
            "type": "string",
            "defaultValue": "[$env:KEYVAULTID]",
            "metadata": {
                "description": "Resource Id of the key vault, is should be in the format of /subscriptions/<Sub ID>/resourceGroups/<Resource group name>/providers/Microsoft.KeyVault/vaults/<vault name>"
            }
        },
        "certificateUrlValue": {
            "type": "string",
            "defaultValue": "[$env:SECRETID]",
            "metadata": {
                "description": "Refers to the location URL in your key vault where the certificate was uploaded, it is should be in the format of https://<name of the vault>.vault.azure.net:443/secrets/<exact location>"
            }
        }
    },
    "variables": {

但是我收到语法错误：

如果在

中省略方括号，也会出现类似错误 
"defaultValue": "$env:THUMBPRINT",

3 个答案:

答案 0 :(得分：3)

您需要在部署任务上设置替代参数。删除所有添加到模板的defaultValues。您的任务Yaml如下所示：

- task: AzureResourceManagerTemplateDeployment@3
  inputs:
    deploymentScope: 'Resource Group'
    action: 'Create Or Update Resource Group'
    overrideParameters: '-certificateThumbprint $(Thumbprint) -sourceVaultResourceId $(vaultId) -certificateUrlValue $(certUrl)'

$（paren）语法是您在任务定义中引用变量的方式-将其更改为您命名的变量。

答案 1 :(得分：2)

您可以通过在其后执行另一个PowerShell步骤并执行Write-Host来验证变量Thumbprint具有该值。

Write-Host $env:THUMBPRINT

您可以使用$ env：THUMBPRINT引用在ARM模板参数中创建的变量

以下是参考链接：https://docs.microsoft.com/en-us/azure/devops/pipelines/process/variables?view=azure-devops&tabs=yaml%2Cbatch

下面是对我有用的，但是Brian建议使用overrideParameters的建议效果更好，因此我将其设置为可接受的答案。

第一件事是我使用错误的格式设置变量。

要正确地进行字符串外推，我必须两次使用$字符（如$($Cert.Thumbprint)中一样），并且我真的不需要;isOutput=true，因为它是一项工作：

# import the self-signed certificate ccg-self-signed-cert into the Keyvault
- task: AzurePowerShell@5
  inputs:
    azureSubscription: '${{ parameters.ArmConnection }}'
    ScriptType: 'InlineScript'
    azurePowerShellVersion: '3.1.0'
    Inline: |
      $Pwd = ConvertTo-SecureString -String 'MyPassword' -Force -AsPlainText
      $Base64 = 'MIIKqQ____3000_CHARS_HERE______1ICAgfQ=='
      $Cert = Import-AzKeyVaultCertificate -VaultName $(KeyVaultName) -Name my-self-signed-cert -CertificateString $Base64 -Password $Pwd
      echo "##vso[task.setvariable variable=Thumbprint]$($Cert.Thumbprint)"
      echo "##vso[task.setvariable variable=SecretId]$($Cert.SecretId)"

然后我添加了一个任务来替换我需要的3个值：

# replace Thumbprint, SecretId and KeyvaultId in the sfcluster-params.json file
- task: replacetokens@3
  displayName: 'Replace tokens in sfcluster-params.json'
  inputs:
    rootDirectory: '$(Build.SourcesDirectory)/pipelines/templates/'
    targetFiles: '$(Build.SourcesDirectory)/pipelines/templates/sfcluster-params.json'
    encoding: 'auto'
    writeBOM: true
    actionOnMissing: 'fail'
    keepToken: false
    tokenPrefix: '$('
    tokenSuffix: ')'

以下是我的整个sfcluster-params.json文件（KEYVAULTID来自keyvault ARM部署）：

{
    "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentParameters.json#",
    "contentVersion": "1.0.0.0",
    "parameters": {
        "clusterName": {
            "value": "my-sfcluster"
        },
        "certificateThumbprint": {
            "value": "$(THUMBPRINT)"
        },
        "sourceVaultResourceId": {
            "value": "$(KEYVAULTID)"
        },
        "certificateUrlValue": {
            "value": "$(SECRETID)"
        }
    }
}

最后我已经部署了SF集群：

# deploy SF cluster by ARM template and use the SF Cluster certificate thumbsprint as admin cert
- task: AzureResourceManagerTemplateDeployment@3
  inputs:
    deploymentScope: 'Resource Group'
    azureResourceManagerConnection: '${{ parameters.ArmConnection }}'
    subscriptionId: 'XXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXX'
    action: 'Create Or Update Resource Group'
    resourceGroupName: '${{ parameters.resourceGroupName }}'
    location: 'West Europe'
    templateLocation: 'Linked artifact'
    csmFile: '$(Build.SourcesDirectory)/pipelines/templates/sfcluster.json'
    csmParametersFile: '$(Build.SourcesDirectory)/pipelines/templates/sfcluster-params.json'
    deploymentMode: 'Incremental'
