Skapa funktionsappresurser i Azure med PowerShell

  • Artikel

Azure PowerShell-exempelskripten i den här artikeln skapar funktionsappar och andra resurser som krävs för att vara värd för dina funktioner i Azure. En funktionsapp tillhandahåller en körningskontext där dina funktioner körs. Alla funktioner som körs i en funktionsapp delar samma resurser och anslutningar, och de skalas alla tillsammans.

När resurserna har skapats kan du distribuera dina projektfiler till den nya funktionsappen. Mer information finns i Distributionsmetoder.

Varje funktionsapp kräver dina PowerShell-skript för att skapa följande resurser:

Resurs Cmdlet Description
Resursgrupp New-AzResourceGroup Skapar en resursgrupp där du skapar funktionsappen.
Lagringskonto New-AzStorageAccount Skapar ett lagringskonto som används av funktionsappen. Lagringskontonamn måste vara mellan 3 och 24 tecken långa och får endast innehålla siffror och gemener. Du kan också använda ett befintligt konto som måste uppfylla kraven för lagringskontot.
App Service-plan New-AzFunctionAppPlan Skapar uttryckligen en värdplan som definierar hur resurser allokeras till din funktionsapp. Används endast när du är värd i en Premium- eller Dedicated-plan. Du kommer inte att använda den här cmdleten när du är värd för en serverlös förbrukningsplan, eftersom förbrukningsplaner skapas när du kör New-AzFunctionApp. Mer information finns i Azure Functions-värdalternativ.
Funktionsapp New-AzFunctionApp Skapar funktionsappen med de resurser som krävs. Parametern -Name måste vara ett globalt unikt namn för hela Azure App Service. Giltiga tecken i -Name är a-z (skiftlägesokänsliga), 0-9, och -. De flesta exempel skapar en funktionsapp som stöder C#-funktioner. Du kan ändra språket med hjälp av parametern -Runtime med värden som stöds för DotNet, Java, Node, PowerShelloch Python. Använd för -RuntimeVersion att välja en specifik språkversion.

Den här artikeln innehåller följande exempel:

Förutsättningar

Om du inte har en Azure-prenumeration skapar du ett kostnadsfritt Azure-konto innan du börjar.

New-AzStorageShare -Name $share -Context $storageContext

# Create a directory in the share.

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

Monterade filresurser stöds endast i Linux. Mer information finns i Montera filresurser.

Rensa resurser

I de föregående stegen skapade du Azure-resurser i en resursgrupp. Om du inte förväntar dig att behöva dessa resurser i framtiden tar du bort resursgruppen genom att köra följande PowerShell-kommando:

Remove-AzResourceGroup -Name myResourceGroup

Det kan några minuter att köra kommandot.
