【中文标题】如何将 Azure 管道变量传递给 AzureResourceManagerTemplateDeployment@3 任务使用的 ARM 模板?【英文标题】:How to pass an Azure pipeline variable to an ARM template used by AzureResourceManagerTemplateDeployment@3 task? 【发布时间】:2020-09-13 18:15:12 【问题描述】:我正在尝试在每天晚上安排的 Azure 管道中执行以下 2 个步骤:
-
将自签名证书放入密钥库
通过 ARM 模板部署 Service Fabric 集群并使用证书指纹和机密 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"
我想我通过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保存证书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 创建一个 SF 集群。
如果您查看它,它需要证书指纹作为参数:
"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 AzurePowerShell@5 任务中的值传递给后续 AzureResourceManagerTemplateDeployment@3 任务使用的 ARM 模板?
更新:
我已尝试遵循 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":
但是我得到了语法错误:
2020-05-27T12:31:54.1327314Z There were errors in your deployment. Error code: InvalidTemplate.
2020-05-27T12:31:54.1354742Z ##[error]Deployment template language expression evaluation failed: 'The language expression '$env:THUMBPRINT' is not valid: the string character ':' at position '4' is not expected.'. Please see https://aka.ms/arm-template-expressions for usage details.
2020-05-27T12:31:54.1361090Z ##[debug]Processed: ##vso[task.issue type=error;]Deployment template language expression evaluation failed: 'The language expression '$env:THUMBPRINT' is not valid: the string character ':' at position '4' is not expected.'. Please see https://aka.ms/arm-template-expressions for usage details.
如果我在
中省略方括号,也会出现类似的错误"defaultValue": "$env:THUMBPRINT",
【问题讨论】:
嗨@Alexander Farber,Nilay 下面的回答是否有助于解决您的问题?检查this rule,如果有帮助,您可以考虑接受它作为答案。这只是一个提醒:) 【参考方案1】:您需要在部署任务上设置覆盖参数。删除您添加到模板中的所有默认值。你的任务 yaml 看起来像:
- 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 - 所以将它们更改为您命名变量的任何名称。
【讨论】:
谢谢布赖恩。我今天终于设法让我的管道正常工作 - 通过调用replacetokens@3
任务(请参阅我自己的答案),但你的建议看起来更好。【参考方案2】:
您可以通过在其后执行另一个 PowerShell 步骤并执行 Write-Host 来验证您的变量 Thumbprint 是否具有该值。
Write-Host $env:THUMBPRINT
您可以使用 $env:THUMBPRINT 引用您在 ARM 模板参数中创建的变量
这是一个参考链接:https://docs.microsoft.com/en-us/azure/devops/pipelines/process/variables?view=azure-devops&tabs=yaml%2Cbatch
【讨论】:
谢谢 Nilay,但是当我在我的 ARM 模板中尝试 ` "defaultValue": "[$env:THUMBPRINT]",` 或"defaultValue": "$env:THUMBPRINT",
时出现语法错误(请参阅我的更新问题)。
@AlexanderFarber bmoore-msft 的建议是正确的做事方式。不要为此使用替换令牌。使用覆盖参数。是的,您可以使用 $(param) 来引用变量。【参考方案3】:
以下是对我有用的方法,但 Brian 建议使用 overrideParameters
效果更好,因此我将其设置为可接受的答案。
首先是我使用了错误的格式来设置变量。
对于正确的字符串外推,我必须使用两次 $
字符(如在 $($Cert.Thumbprint)
中),我真的不需要 ;isOutput=true
,因为它是一个单一的工作:
# 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: ')'
虽然我的整个 sfcluster-params.json 文件如下(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'
