練習 - 將參數新增至部署指令碼

8 分鐘

由於您已使用部署指令碼將一些手動工作遷移至 Azure Resource Manager (ARM) 範本，組織中有另一個合作夥伴應用程式小組需要一些協助。

該小組的程序有類似的需求，但該小組需要將多個檔案部署到儲存體帳戶。該小組有個 PowerShell 指令碼可將檔案清單當作參數並上傳檔案，類似於您已在範本中使用的指令碼。

在此練習中，您將上一個範本當作起點，並更新 PowerShell 指令碼來使用夥伴小組的範本。然後，您將新增方法，讓部署範本的人員指定要部署的設定檔 (一或多個)。

在此過程中，您將會：

更新部署指令碼。
新增環境變數和範本參數，並傳給部署指令碼。
將輸出新增至部署指令碼。
新增參數檔案。
部署範本並驗證結果。

建立起始範本

從您在上一個練習中建立的範本開始。

開啟 Visual Studio Code，並建立一個名為 azuredeploy.json 的新檔案。

將下列起始範本複製到 azuredeploy.json。

儲存範本。

開啟 Visual Studio Code，並建立一個名為 main.bicep 的新檔案。

將下列起始範本複製到 main.bicep。

var storageAccountName = 'storage${uniqueString(resourceGroup().id)}'
var storageBlobContainerName = 'config'
var userAssignedIdentityName = 'configDeployer'
var roleAssignmentName = guid(resourceGroup().id, 'contributor')

}

output fileUri string = deploymentScript.properties.outputs.Uri

儲存範本。

更新 PowerShell 指令碼

因為另一個小組已努力建立 PowerShell 指令碼來複製多個檔案，您決定在範本中使用該指令碼。

在 properties 區段中編輯 scriptContent，以包含夥伴小組提供的指令碼。

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."

新增環境變數

您採用的指令碼需要某些環境變數。您可以直接在範本中指定環境變數，但使用範本函式來取得一些值會更有彈性。

將 environmentVariables 屬性新增至部署指令碼的 properties 區段。
```
"environmentVariables": [
],
```

新增 ResourceGroupName 的環境變數。

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

新增 StorageAccountName 的環境變數。

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

新增 StorageContainerName 的環境變數。

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

提示

使用範本函式來存取一般值，例如 [resourceGroup().name] 和 [variables()]。

您採用的指令碼需要某些環境變數。您可以直接在範本中指定環境變數，但使用 Bicep 變數來取得一些值會更有彈性。

將 environmentVariables 屬性新增至部署指令碼的 properties 區段。
```
environmentVariables: [
]
```

新增 ResourceGroupName 的環境變數。

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

新增 StorageAccountName 的環境變數。

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

新增 StorageContainerName 的環境變數。

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

新增範本參數

為了讓兩個小組更輕鬆使用您的範本，您可以將參數新增至範本，讓每個小組指定想要複製的檔案。

將參數新增至範本，以接受檔案名稱的陣列。

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

此外，您可以提供預設值，無須變更部署程序，範本就能繼續供小組使用。雖然並非必要，但輸入新的預設值可協助您了解讓小組更容易採用新版本範本的模式，如果他們繼續如先前一般的行為，新功能就會是獎勵。換句話說，此步驟會說明如何保有現有的行為，同時進行變更以支援未來的工作。

將參數新增至範本，以接受檔案名稱的陣列。

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

新增引數以傳入要複製的檔案中

接下來，您可以取得剛定義的參數，並傳給部署指令碼。傳遞命令列引數可能較複雜，因為字串需要經過多層評估。成功是關鍵在於正確逸出引號，並為作業挑選正確引號。

提示

使用範本函式來存取常用的函式，例如 [string()] 將一種型別的值轉換成字串。

將 arguments 屬性新增至部署指令碼。 PowerShell 指令碼接受名為 File 的參數，這是應該來自 filesToCopy 範本參數的一串檔案名稱。請確定有引號括住整個引數，因此可正確傳入引數。

警告

此 arguments 屬性無效。如果是在 Visual Studio Code 中使用 Azure Resource Manager 擴充，可能會標示這一行。您將在後續步驟中解決此問題。
```
"arguments": "[concat( '-File '', string(parameters('filesToCopy')), ''' )]",
```
提示

在 JSON 中使用引號可能很困難，尤其是在傳入命令列引數時。您可以使用範本變數來代表很難逸出的字元。

新增範本變數以代表單引號字元。

"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"
},

以您剛定義的變數取代 arguments 屬性中的單引號。

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

將 arguments 屬性新增至部署指令碼。 PowerShell 指令碼接受名為 File 的參數，這是應該來自 filesToCopy 範本參數的一串檔案名稱。

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

請注意，這用到幾個 Bicep 功能：

字串插補，用來合併字串。
我們使用 \ 逸出字元，以讓我們在字串內加入單引號字元 (')，因為單引號通常是 Bicep 中的保留字元。
我們使用 string() 函式來將 filesToCopy 陣列轉換成字串。

更新範本輸出

因為您想變更部署指令碼來部署一個或多個檔案，所以需要更新範本輸出，以提供所有必要的資訊。

在範本中更新 outputs 以傳回整個物件，而每個檔案都有一個 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++
}

以儲存體帳戶名稱 (具有隨機識別碼) 新增另一個輸出。稍後會使用此輸出，以驗證部署指令碼的動作是否符合您的預期。

$DeploymentScriptOutputs = @{}
foreach ($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++
}

在範本中更新輸出以傳回整個物件，而每個檔案都有一個 URI。
```
output fileUri object = deploymentScript.properties.outputs
```
以儲存體帳戶名稱 (具有隨機識別碼) 新增另一個輸出。稍後會使用此輸出，以驗證部署指令碼的動作是否符合您的預期。
```
output storageAccountName string = storageAccountName
```

否則，請複製範例或調整範本，以符合範例。

建立參數檔案

既然您已設定範本，您可以使用參數檔案並指定新檔案，以驗證新的部署指令碼。

手動建立 azuredeploy.parameters.json 檔案，或使用 VS Code 擴充來這樣做。

編輯該檔案以指定兩個 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"
            ]
        }
    }
}

建立 azuredeploy.parameters.json 檔案。

編輯該檔案以指定兩個 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"
            ]
        }
    }
}

部署範本

建立練習的資源群組

您必須建立資源群組，以包含您將在此練習中建立的資源。由於使用新的資源群組，完成練習之後會很容易清理。

從 Visual Studio Code 中的終端，執行此命令以建立此練習的資源群組。

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

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

將範本部署至 Azure

在 Visual Studio Code 終端中，使用 Azure CLI 命令部署範本。

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

將範本部署至 Azure

在終端中使用 Azure PowerShell 命令來部署範本。

$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

將範本部署至 Azure

在 Visual Studio Code 終端中，使用 Azure CLI 命令部署範本。

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

將範本部署至 Azure

在終端中使用 Azure PowerShell 命令來部署範本。

$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

檢閱範本的結果

部署完成之後，您可以列出 blob 容器的內容，以驗證這兩個檔案都已複製到儲存體帳戶。

列出 blob 容器的內容。

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'

命令會傳回下列程式碼：

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

您也可以從 Azure 入口網站或使用下列命令，以檢閱記錄 (以及部署的其他詳細資料)。
```
az deployment-scripts show-log --resource-group $resourceGroupName --name CopyConfigScript
```

列出 blob 容器的內容。

$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

命令會傳回下列程式碼：

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

您也可以從 Azure 入口網站或使用下列命令，以檢閱記錄 (以及部署的其他詳細資料)。
```
Get-AzDeploymentScriptLog -ResourceGroupName $resourceGroupName -Name CopyConfigScript
```

清理資源群組

您已使用部署指令碼來成功部署 ARM 範本，並使用不同的方法傳入資料來自訂行為。您可以移除資源群組，其中包含您已建立的所有資源和角色指派。

az group delete --name $resourceGroupName

Remove-AzResourceGroup -Name $resourceGroupName
