使用 PowerShell 在 Azure 中建立函數應用程式資源

本文中的 Azure PowerShell 範例指令碼會建立在 Azure 中裝載函數所需的函數應用程式以及其他資源。 函數應用程式提供您的函數可在其中執行的執行內容。 在函數應用程式中執行的所有函數都會共用相同的資源和連線，而且全都會一起調整。

建立資源之後，您可以將專案檔部署到新的函數應用程式。 若要深入了解，請參閱部署方法。

每個函數應用程式都需要 PowerShell 指令碼來建立下列資源：

資源	Cmdlet	描述
資源群組	New-AzResourceGroup	建立您會在其中建立函數應用程式的資源群組。
儲存體帳戶	New-AzStorageAccount	建立您函數應用程式所使用的儲存體帳戶。 儲存體帳戶名稱必須介於 3 到 24 個字元的長度，而且只能包含數字和小寫字母。 您也可以使用現有帳戶，條件是必須符合儲存體帳戶需求。
App Service 方案	New-AzFunctionAppPlan	明確建立會定義如何將資源配置給函數應用程式的主控方案。 只有在裝載於進階或專用方案中時才會使用。 在無伺服器取用方案中裝載時，不會使用此 Cmdlet，因為執行 New-AzFunctionApp 時會建立取用方案。 如需詳細資訊，請參閱 Azure Functions 裝載選項。
函式應用程式	New-AzFunctionApp	使用必要的資源建立函數應用程式。 參數 -Name 必須是所有 Azure App Service 的全域唯一名稱。 -Name 中的有效字元為 a-z (區分大小寫)、0-9 及 -。 大部分範例都會建立支援 C# 函數的函數應用程式。 您可以使用參數 -Runtime 來變更語言，其支援值為 DotNet、Java、Node、PowerShell 及 Python。 使用 -RuntimeVersion 來選擇特定語言版本。

本文包含下列範例：

• 為 C# 建立無伺服器函數應用程式
• 為 Python 建立無伺服器函數應用程式
• 在進階方案中建立可調整的函數應用程式
• 在專用方案中建立函數應用程式
• 建立具有具名儲存體連線的函數應用程式
• 使用 Azure Cosmos DB 連線建立函數應用程式
• 建立具有持續部署的函數應用程式
• 建立無伺服器 Python 函數應用程式和掛接檔案共用

必要條件

• 如果您選擇在本機使用 Azure PowerShell：
  • 安裝最新版的 Az PowerShell 模組。
  • 使用 Connect-AzAccount Cmdlet 連線至 Azure 帳戶。
• 如果您選擇使用 Azure Cloud Shell：
  • 請參閱 Azure Cloud Shell 概觀 以取得詳細資訊。

如果您沒有 Azure 訂用帳戶，請在開始之前先建立 Azure 免費帳戶。

# Create a resource group
Write-Host "Creating $resourceGroup in $location..."
New-AzResourceGroup -Name $resourceGroup -Location $location -Tag $tag

# Create an Azure storage account in the resource group.
Write-Host "Creating $storage"
New-AzStorageAccount -Name $storage -Location $location -ResourceGroupName $resourceGroup -SkuName $skuStorage

# Get the storage account key. 
$keys = Get-AzStorageAccountKey -Name $storage -ResourceGroupName $resourceGroup
$storageKey = $keys[0].Value

## Create a serverless Python function app in the resource group.
Write-Host "Creating $functionApp"

New-AzStorageShare -Name $share -Context $storageContext

# Create a directory in the share.
Write-Host "Creating $directory in $share"
New-AzStorageDirectory -ShareName $share -Path $directory -Context $storageContext

# Add a storage account configuration to the function app
Write-Host "Adding $storage configuration"
$storagePath = New-AzWebAppAzureStoragePath -Name $shareid -Type AzureFiles -ShareName $share -AccountName $storage -MountPath $mountPath -AccessKey $storageKey
Set-AzWebApp -Name $functionApp -ResourceGroupName $resourceGroup -AzureStoragePath $storagePath 

# Get a function app's storage account configurations.
(Get-AzWebApp -Name $functionApp -ResourceGroupName $resourceGroup).AzureStoragePath

只有在 Linux 才支援掛接的檔案共用。 如需詳細資訊，請參閱掛接檔案共用。

清除資源

在上述步驟中，您已建立資源群組中的 Azure 資源。 若您預期未來不需要使用這些資源，請執行下列 PowerShell 命令來刪除資源群組：

Remove-AzResourceGroup -Name myResourceGroup

此命令可能會花一分鐘執行。
