Creare risorse dell'app per le funzioni in Azure con PowerShell

  • Articolo

Gli script di esempio di Azure PowerShell in questo articolo creano app per le funzioni e altre risorse necessarie per ospitare le funzioni in Azure. Un'app per le funzioni fornisce un contesto di esecuzione in cui vengono eseguite le funzioni. Tutte le funzioni in esecuzione in un'app per le funzioni condividono le stesse risorse e le stesse connessioni e vengono tutte ridimensionate insieme.

Dopo aver creato le risorse, è possibile distribuire i file di progetto nella nuova app per le funzioni. Per altre informazioni, vedere Metodi di distribuzione.

Ogni app per le funzioni richiede che gli script di PowerShell creino le risorse seguenti:

Risorsa Cmdlet Descrizione
Gruppo di risorse New-AzResourceGroup Crea un gruppo di risorse in cui si creerà l'app per le funzioni.
Account di archiviazione New-AzStorageAccount Crea un account di archiviazione usato dall'app per le funzioni. I nomi degli account di archiviazione devono avere una lunghezza compresa tra 3 e 24 caratteri e possono contenere solo numeri e lettere minuscole. È anche possibile usare un account esistente, che deve soddisfare i requisiti dell'account di archiviazione.
Piano di servizio app New-AzFunctionAppPlan Crea in modo esplicito un piano di hosting, che definisce la modalità di allocazione delle risorse all'app per le funzioni. Usato solo quando si ospita in un piano Premium o Dedicato. Questo cmdlet non verrà usato quando si ospita in un piano a consumo serverless, poiché i piani a consumo vengono creati quando si esegue New-AzFunctionApp. Per altre informazioni, vedere Opzioni di hosting di Funzioni di Azure.
App per le funzioni New-AzFunctionApp Crea l'app per le funzioni usando le risorse necessarie. Il -Name parametro deve essere un nome univoco globale in tutto il servizio app Azure. I caratteri validi in -Name sono a-z (senza distinzione tra maiuscole e minuscole), 0-9e -. La maggior parte degli esempi crea un'app per le funzioni che supporta funzioni C#. È possibile modificare la lingua usando il -Runtime parametro , con i valori supportati di DotNet, JavaNode, PowerShell, e Python. -RuntimeVersion Usare per scegliere una versione specifica della lingua.

Questo articolo contiene gli esempi seguenti:

Prerequisiti

Se non si ha una sottoscrizione di Azure, creare un account Azure gratuito prima di iniziare.

Set-AzWebApp -Name $functionApp -ResourceGroupName $resourceGroup -AzureStoragePath $storagePath 

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

Le condivisioni file montate sono supportate solo in Linux. Per altre informazioni, vedere Montare condivisioni file.

Pulire le risorse

Nei passaggi precedenti sono state create risorse di Azure in un gruppo di risorse. Se non si prevede che queste risorse siano necessarie in futuro, eliminare il gruppo di risorse eseguendo il comando di PowerShell seguente:

Remove-AzResourceGroup -Name myResourceGroup

L'esecuzione del comando può richiedere un minuto.
