练习 - 向部署脚本添加参数

  • 8 分钟

现在你已使用部署脚本将一些手动工作迁移到 Azure 资源管理器 (ARM) 模板中，组织中的另一个合作伙伴应用程序团队已向你请求帮助。

该团队的流程有类似的要求，但他们需要将多个文件部署到其存储帐户。 该团队有一个 PowerShell 脚本可将文件列表作为参数上传，类似于已在模板中使用的脚本。

在本练习中，你将以之前的模板作为起点，并更新 PowerShell 脚本以使用合作伙伴团队提供的模板。 然后，将添加一种方法，使部署模板的人员能够指定要部署的配置文件（一个或多个）。

在此过程中，你将：

  • 更新部署脚本。
  • 添加环境变量和模板参数，并将其传递给部署脚本。
  • 将输出添加到部署脚本。
  • 添加参数文件。
  • 部署模板，并验证结果。

创建共享模板

可以从在上一练习中创建的模板入手。

  1. 打开 Visual Studio Code 并创建名为 azuredeploy.json 的新文件。

  2. 将以下起始模板复制到 azuredeploy.json 中。

    {
    "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
    "contentVersion": "1.0.0.1",

            ],
            "properties": {
                "publicAccess": "Blob"
            }
        },
        {
            "type": "Microsoft.ManagedIdentity/userAssignedIdentities",
            "apiVersion": "2018-11-30",

                "scope": "[resourceGroup().id]",
                "principalType": "ServicePrincipal"
            }
        },
        {
            "type": "Microsoft.Resources/deploymentScripts",
            "apiVersion": "2020-10-01",

                "[resourceId('Microsoft.Storage/storageAccounts/blobServices/containers', variables('storageAccountName'), 'default', variables('storageBlobContainerName'))]"
            ],
            "identity": {
                "type": "UserAssigned",
                "userAssignedIdentities": {
                    "[resourceId('Microsoft.ManagedIdentity/userAssignedIdentities',variables('userAssignedIdentityName'))]": {}

                    $storageAccount = Get-AzStorageAccount -ResourceGroupName 'learndeploymentscript_exercise_1' | Where-Object { $_.StorageAccountName -like 'storage*' }
                    $blob = Set-AzStorageBlobContent -File 'appsettings.json' -Container 'config' -Blob 'appsettings.json' -Context $StorageAccount.Context
                    $DeploymentScriptOutputs = @{}
                    $DeploymentScriptOutputs['Uri'] = $blob.ICloudBlob.Uri
                    $DeploymentScriptOutputs['StorageUri'] = $blob.ICloudBlob.StorageUri
                ",
                "retentionInterval": "P1D"
            }

            "value": "[reference(variables('deploymentScriptName')).outputs.Uri]"
        }
    }
}

  3. 保存模板。

  1. 打开 Visual Studio Code，并创建名为 main.bicep 的新文件。

  2. 将以下起始模板复制到 main.bicep 中。

    var storageAccountName = 'storage${uniqueString(resourceGroup().id)}'
var storageBlobContainerName = 'config'
var userAssignedIdentityName = 'configDeployer'
var roleAssignmentName = guid(resourceGroup().id, 'contributor')
var contributorRoleDefinitionId = resourceId('Microsoft.Authorization/roleDefinitions', 'b24988ac-6180-42a0-ab88-20f7382dd24c')
var deploymentScriptName = 'CopyConfigScript'

resource storageAccount 'Microsoft.Storage/storageAccounts@2023-01-01' = {
  name: storageAccountName
  tags: {
    displayName: storageAccountName
  }
  location: resourceGroup().location
  kind: 'StorageV2'
  sku: {
    name: 'Standard_LRS'
    tier: 'Standard'
  }
  properties: {
    allowBlobPublicAccess: true
    encryption: {
      services: {
        blob: {
          enabled: true
        }
      }
      keySource: 'Microsoft.Storage'
    }
    supportsHttpsTrafficOnly: true
  }

  resource blobService 'blobServices' existing = {
    name: 'default'
  }
}

resource blobContainer 'Microsoft.Storage/storageAccounts/blobServices/containers@2019-04-01' = {
  parent: storageAccount::blobService
  name: storageBlobContainerName
  properties: {
    publicAccess: 'Blob'
  }
}

resource userAssignedIdentity 'Microsoft.ManagedIdentity/userAssignedIdentities@2018-11-30' = {
  name: userAssignedIdentityName
  location: resourceGroup().location
}

resource roleAssignment 'Microsoft.Authorization/roleAssignments@2020-04-01-preview' = {
  name: roleAssignmentName
  properties: {
    roleDefinitionId: contributorRoleDefinitionId
    principalId: userAssignedIdentity.properties.principalId
    principalType: 'ServicePrincipal'
  }
}

resource deploymentScript 'Microsoft.Resources/deploymentScripts@2020-10-01' = {
  name: deploymentScriptName
  location: resourceGroup().location
  kind: 'AzurePowerShell'
  identity: {
    type: 'UserAssigned'
    userAssignedIdentities: {
      '${userAssignedIdentity.id}': {}
    }
  }
  properties: {
    azPowerShellVersion: '3.0'
    scriptContent: '''
      Invoke-RestMethod -Uri 'https://raw.githubusercontent.com/Azure/azure-docs-json-samples/master/mslearn-arm-deploymentscripts-sample/appsettings.json' -OutFile 'appsettings.json'
      $storageAccount = Get-AzStorageAccount -ResourceGroupName 'learndeploymentscript_exercise_1' | Where-Object { $_.StorageAccountName -like 'storage*' }
      $blob = Set-AzStorageBlobContent -File 'appsettings.json' -Container 'config' -Blob 'appsettings.json' -Context $storageAccount.Context
      $DeploymentScriptOutputs = @{}
      $DeploymentScriptOutputs['Uri'] = $blob.ICloudBlob.Uri
      $DeploymentScriptOutputs['StorageUri'] = $blob.ICloudBlob.StorageUri
    '''
    retentionInterval: 'P1D'
  }
  dependsOn: [
    roleAssignment
    blobContainer
  ]
}

output fileUri string = deploymentScript.properties.outputs.Uri

  3. 保存模板。

更新 PowerShell 脚本

由于另一个团队已经完成了创建 PowerShell 脚本（用于复制多个文件）的艰难任务，因此你决定在模板中使用该脚本。

对 properties 部分中的 scriptContent 进行编辑，使其包含合作伙伴团队提供的脚本。

param([string]$File)
$fileList = $File -replace '(\[|\])' -split ',' | ForEach-Object { $_.trim() }
$storageAccount = Get-AzStorageAccount -ResourceGroupName $env:ResourceGroupName -Name $env:StorageAccountName -Verbose
$count = 0
$DeploymentScriptOutputs = @{}
foreach ($fileName in $fileList) {
    Write-Host \"Copying $fileName to $env:StorageContainerName in $env:StorageAccountName.\"
    Invoke-RestMethod -Uri \"https://raw.githubusercontent.com/Azure/azure-docs-json-samples/master/mslearn-arm-deploymentscripts-sample/$fileName\" -OutFile $fileName
    $blob = Set-AzStorageBlobContent -File $fileName -Container $env:StorageContainerName -Blob $fileName -Context $storageAccount.Context
    $DeploymentScriptOutputs[$fileName] = @{}
    $DeploymentScriptOutputs[$fileName]['Uri'] = $blob.ICloudBlob.Uri
    $DeploymentScriptOutputs[$fileName]['StorageUri'] =$blob.ICloudBlob.StorageUri
    $count++
}
Write-Host \"Finished copying $count files.\"

param([string]$File)
$fileList = $File -replace '(\[|\])' -split ',' | ForEach-Object { $_.trim() }
$storageAccount = Get-AzStorageAccount -ResourceGroupName $env:ResourceGroupName -Name $env:StorageAccountName -Verbose
$count = 0
$DeploymentScriptOutputs = @{}
foreach ($fileName in $fileList) {
    Write-Host "Copying $fileName to $env:StorageContainerName in $env:StorageAccountName."
    Invoke-RestMethod -Uri "https://raw.githubusercontent.com/Azure/azure-docs-json-samples/master/mslearn-arm-deploymentscripts-sample/$fileName" -OutFile $fileName
    $blob = Set-AzStorageBlobContent -File $fileName -Container $env:StorageContainerName -Blob $fileName -Context $storageAccount.Context
    $DeploymentScriptOutputs[$fileName] = @{}
    $DeploymentScriptOutputs[$fileName]['Uri'] = $blob.ICloudBlob.Uri
    $DeploymentScriptOutputs[$fileName]['StorageUri'] = $blob.ICloudBlob.StorageUri
    $count++
}
Write-Host "Finished copying $count files."

添加环境变量

所采用的脚本需要某些环境变量。 可以直接在模板中指定它们，但使用模板函数获取一些值将更加灵活。

  1. 将 environmentVariables 属性添加到部署脚本的 properties 部分。

    "environmentVariables": [
],

  2. 添加 ResourceGroupName 的环境变量。

    "environmentVariables": [
    {
        "name": "ResourceGroupName",
        "value": "[resourceGroup().name]"
    }
],

  3. 添加 StorageAccountName 的环境变量。

    "environmentVariables": [
    {
        "name": "ResourceGroupName",
        "value": "[resourceGroup().name]"
    },
    {
        "name": "StorageAccountName",
        "value": "[variables('storageAccountName')]"
    }
],

  4. 添加 StorageContainerName 的环境变量。

    "environmentVariables": [
    {
        "name": "ResourceGroupName",
        "value": "[resourceGroup().name]"
    },
    {
        "name": "StorageAccountName",
        "value": "[variables('storageAccountName')]"
    },
    {
        "name": "StorageContainerName",
        "value": "[variables('storageBlobContainerName')]"
    }
],

提示

使用模板函数访问常用值，例如 [resourceGroup().name] 和 [variables()]。

所采用的脚本需要某些环境变量。 可以直接在模板中指定它们，但使用 Bicep 变量获取一些值将更加灵活。

  1. 将 environmentVariables 属性添加到部署脚本的 properties 部分。

    environmentVariables: [
]

  2. 添加 ResourceGroupName 的环境变量。

    environmentVariables: [
  {
    name: 'ResourceGroupName'
    value: resourceGroup().name
  }
]

  3. 添加 StorageAccountName 的环境变量。

    environmentVariables: [
  {
    name: 'ResourceGroupName'
    value: resourceGroup().name
  }
  {
    name: 'StorageAccountName'
    value: storageAccountName
  }
]

  4. 添加 StorageContainerName 的环境变量。

    environmentVariables: [
  {
    name: 'ResourceGroupName'
    value: resourceGroup().name
  }
  {
    name: 'StorageAccountName'
    value: storageAccountName
  }
  {
    name: 'StorageContainerName'
    value: storageBlobContainerName
  }
]

添加模板参数

为了让这两个团队可以更轻松地使用模板，可将向模板添加一个参数，使每个团队都可以指定要复制的文件。

将参数添加到模板以采用文件名数组。

"parameters": {
    "filesToCopy": {
        "type": "array",
        "metadata": {
            "description": "List of files to copy to application storage account."
        }
    }
},

这样，就可以提供默认值，让团队能够继续使用模板，而无需更改部署过程。 虽然不是必需的，但输入新的默认值可以帮助你理解更易于团队采用新版模板的模式（如果其行为和之前一样），还能获得新功能作为回报。 换句话说，此步骤展示了在通过更改来支持将来的工作的同时，如何维护现有行为。

将参数添加到模板以采用文件名数组。

@description('List of files to copy to application storage account.')
param filesToCopy array

这样，就可以提供默认值，让团队能够继续使用模板，而无需更改部署过程。 虽然不是必需的，但输入新的默认值可以帮助你理解更易于团队采用新版模板的模式（如果其行为和之前一样），还能获得新功能作为回报。 换句话说，此步骤展示了在通过更改来支持将来的工作的同时，如何维护现有行为。

添加参数以传入要复制的文件

接下来，你可以获取刚定义的参数，并将其传递给部署脚本。 传递命令行参数可能很棘手，因为字符串是在多个级别进行评估的。 正确转义引号并为作业选择正确的引号对于取得成功至关重要。

提示

使用模板函数访问 [string()] 等常用函数，将某种类型的值转换为字符串。

  1. 将 arguments 属性添加到部署脚本。 PowerShell 脚本采用名为 File 的参数，该参数是应来自 filesToCopy 模板参数的文件名的字符串。 请确保整个参数用引号括起，以便正确传递。

    注意

    此 arguments 属性无效。 如果在 Visual Studio Code 中使用 Azure 资源管理器扩展，则可能会标记此行。 你将在后续步骤中解决此问题。

    "arguments": "[concat( '-File '', string(parameters('filesToCopy')), ''' )]",

    提示

    在 JSON 中对内容使用引号可能很难，尤其是在传入命令行参数时。 可以使用模板变量来表示难以转义的字符。

  2. 添加一个模板变量来表示单引号字符。

    "variables": {
    "singleQuote": "'",
    "storageAccountName": "[concat('storage', uniqueString(resourceGroup().id))]",
    "storageBlobContainerName": "config",
    "userAssignedIdentityName": "configDeployer",
    "roleAssignmentName": "[guid(concat(resourceGroup().id, 'contributor'))]",
    "contributorRoleDefinitionId": "[resourceId('Microsoft.Authorization/roleDefinitions', 'b24988ac-6180-42a0-ab88-20f7382dd24c')]",
    "deploymentScriptName": "CopyConfigScript"
},

  3. 将 arguments 属性中的单引号替换为刚定义的变量。

    "arguments": "[concat( '-File ', variables('singleQuote'), string(parameters('filesToCopy')), variables('singleQuote'))]",

接下来，你可以获取刚定义的参数，并将其传递给部署脚本。 传递命令行参数可能很棘手，因为字符串是在多个级别进行评估的。 正确转义引号并为作业选择正确的引号对于取得成功至关重要。

将 arguments 属性添加到部署脚本。 PowerShell 脚本采用名为 File 的参数，该参数是应来自 filesToCopy 模板参数的文件名的字符串。

arguments: '-File \'${string(filesToCopy)}\''

请注意，这将使用多个 Bicep 功能：

  • 字符串内插，用于合并字符串。
  • 我们使用 \ 转义字符在字符串中包含单引号字符 (')，因为单引号通常是 Bicep 中的保留字符。
  • 我们使用 string() 函数将 filesToCopy 数组转换为字符串。

更新模板输出

因为你要更改部署脚本以部署一个或多个文件，所以需要更新模板输出以提供所有必需的信息。

  1. 更新模板中的 outputs 以返回整个对象（每个文件都将有一个 URI）。

    $DeploymentScriptOutputs = @{}
foreach ($fileName in $fileList) {
    Write-Host \"Copying $fileName to $env:StorageContainerName in $env:StorageAccountName.\"
    Invoke-RestMethod -Uri \"https://raw.githubusercontent.com/Azure/azure-docs-json-samples/master/mslearn-arm-deploymentscripts-sample/$fileName\" -OutFile $fileName
    $blob = Set-AzStorageBlobContent -File $fileName -Container $env:StorageContainerName -Blob $fileName -Context $storageAccount.Context
    $DeploymentScriptOutputs[$fileName] = @{}
    $DeploymentScriptOutputs[$fileName]['Uri'] = $blob.ICloudBlob.Uri
    $DeploymentScriptOutputs[$fileName]['StorageUri'] =$blob.ICloudBlob.StorageUri
    $count++
}

  2. 使用存储帐户名称（具有随机标识符）添加另一个输出。 稍后你将使用它来验证部署脚本是否执行了预期的操作。

    $DeploymentScriptOutputs = @{}
foreach ($fileName in $fileList) {
    Write-Host \"Copying $fileName to $env:StorageContainerName in $env:StorageAccountName.\"
    Invoke-RestMethod -Uri \"https://raw.githubusercontent.com/Azure/azure-docs-json-samples/master/mslearn-arm-deploymentscripts-sample/$fileName\" -OutFile $fileName
    $blob = Set-AzStorageBlobContent -File $fileName -Container $env:StorageContainerName -Blob $fileName -Context $storageAccount.Context
    $DeploymentScriptOutputs[$fileName] = @{}
    $DeploymentScriptOutputs[$fileName]['Uri'] = $blob.ICloudBlob.Uri
    $DeploymentScriptOutputs[$fileName]['StorageUri'] =$blob.ICloudBlob.StorageUri
    $count++
}

  1. 更新模板中的输出以返回整个对象（每个文件都将有一个 URI）。

    output fileUri object = deploymentScript.properties.outputs

  2. 使用存储帐户名称（具有随机标识符）添加另一个输出。 稍后你将使用它来验证部署脚本是否执行了预期的操作。

    output storageAccountName string = storageAccountName

验证模板

模板的外观应类似于：

如果不是，请复制示例或调整模板以与该示例一致。

创建参数文件

现在，你已设置好模板，接下来可以使用指定了新文件的参数文件来验证新的部署脚本。

  1. 手动创建 azuredeploy.parameters.json 文件或使用 VS Code 扩展来执行此操作。

  2. 编辑文件以指定两个 filesToCopy：

    {
    "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentParameters.json#",
    "contentVersion": "1.0.0.0",
    "parameters": {
        "filesToCopy": {
            "value": [
                "swagger.Staging.json",
                "appsettings.Staging.json"
            ]
        }
    }
}

  1. 创建 azuredeploy.parameters.json 文件。

  2. 编辑文件以指定两个 filesToCopy：

    {
    "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentParameters.json#",
    "contentVersion": "1.0.0.0",
    "parameters": {
        "filesToCopy": {
            "value": [
                "swagger.Staging.json",
                "appsettings.Staging.json"
            ]
        }
    }
}

部署模板

为此练习创建资源组

你需要创建一个资源组，使其包含将在本练习中创建的资源。 通过使用新的资源组，可在练习后更轻松地进行清理。

在 Visual Studio Code 的终端中运行以下命令，为此练习创建资源组。

resourceGroupName="learndeploymentscript_exercise_2"
az group create --location eastus --name $resourceGroupName

$resourceGroupName = 'learndeploymentscript_exercise_2'
New-AzResourceGroup -Location eastus -Name $resourceGroupName

将模板部署到 Azure

在 Visual Studio Code 终端中使用 Azure CLI 命令部署模板。

templateFile="azuredeploy.json"
templateParameterFile="azuredeploy.parameters.json"
today=$(date +"%d-%b-%Y")
deploymentName="deploymentscript-"$today

az deployment group create \
    --resource-group $resourceGroupName \
    --name $deploymentName \
    --template-file $templateFile \
    --parameters $templateParameterFile

将模板部署到 Azure

在终端中使用 Azure PowerShell 命令部署模板。

$templateFile = 'azuredeploy.json'
$templateParameterFile = 'azuredeploy.parameters.json'
$today = Get-Date -Format 'MM-dd-yyyy'
$deploymentName = "deploymentscript-$today"

New-AzResourceGroupDeployment `
    -ResourceGroupName $resourceGroupName `
    -Name $deploymentName `
    -TemplateFile $templateFile `
    -TemplateParameterFile $templateParameterFile

将模板部署到 Azure

在 Visual Studio Code 终端中使用 Azure CLI 命令部署模板。

templateFile="main.bicep"
templateParameterFile="azuredeploy.parameters.json"
today=$(date +"%d-%b-%Y")
deploymentName="deploymentscript-"$today

az deployment group create \
    --resource-group $resourceGroupName \
    --name $deploymentName \
    --template-file $templateFile \
    --parameters $templateParameterFile

将模板部署到 Azure

在终端中使用 Azure PowerShell 命令部署模板。

$templateFile = 'main.bicep'
$templateParameterFile = 'azuredeploy.parameters.json'
$today = Get-Date -Format 'MM-dd-yyyy'
$deploymentName = "deploymentscript-$today"

New-AzResourceGroupDeployment `
    -ResourceGroupName $resourceGroupName `
    -Name $deploymentName `
    -TemplateFile $templateFile `
    -TemplateParameterFile $templateParameterFile

查看模板结果

部署完成后，可通过列出 Blob 容器的内容来验证这两个文件是否已复制到存储帐户。

  1. 列出 Blob 容器的内容。

    storageAccountName=$(az deployment group show --resource-group $resourceGroupName --name $deploymentName --query 'properties.outputs.storageAccountName.value' --output tsv)
az storage blob list --account-name $storageAccountName --container-name config --query '[].name'

    命令会返回以下代码：

    [
  "swagger.Staging.json",
  "appsettings.Staging.json"
]

  2. 还可以通过 Azure 门户或使用以下命令查看日志（以及有关部署的其他详细信息）。

    az deployment-scripts show-log --resource-group $resourceGroupName --name CopyConfigScript

  1. 列出 Blob 容器的内容。

    $storageAccountName = (Get-AzResourceGroupDeployment -ResourceGroupName $resourceGroupName -Name $deploymentName).Outputs.storageAccountName.Value
$storageAccount = Get-AzStorageAccount -ResourceGroupName $resourceGroupName
Get-AzStorageBlob -Context $storageAccount.Context -Container config |
    Select-Object Name

    命令会返回以下代码：

    Name
----
swagger.Staging.json
appsettings.Staging.json

  2. 还可以通过 Azure 门户或使用以下命令查看日志（以及有关部署的其他详细信息）。

    Get-AzDeploymentScriptLog -ResourceGroupName $resourceGroupName -Name CopyConfigScript

清理资源组

你已成功使用部署脚本部署 ARM 模板，并使用不同的方法来传入数据以自定义其行为。 接下来，可以删除包含已创建的所有资源和角色分配的资源组。

az group delete --name $resourceGroupName

Remove-AzResourceGroup -Name $resourceGroupName
