Create a function app for serverless code execution
This Azure Functions sample script creates a function app, which is a container for your functions. The function app is created using the Consumption plan, which is ideal for event-driven serverless workloads.
If you prefer to run CLI reference commands locally, install the Azure CLI. If you're running on Windows or macOS, consider running Azure CLI in a Docker container. For more information, see How to run the Azure CLI in a Docker container.
If you're using a local installation, sign in to the Azure CLI by using the az login command. To finish the authentication process, follow the steps displayed in your terminal. For other sign-in options, see Sign in with the Azure CLI.
When you're prompted, install the Azure CLI extension on first use. For more information about extensions, see Use extensions with the Azure CLI.
Launch Azure Cloud Shell
The Azure Cloud Shell is a free interactive shell that you can use to run the steps in this article. It has common Azure tools preinstalled and configured to use with your account.
To open the Cloud Shell, just select Try it from the upper right corner of a code block. You can also launch Cloud Shell in a separate browser tab by going to https://shell.azure.com.
When Cloud Shell opens, verify that Bash is selected for your environment. Subsequent sessions will use Azure CLI in a Bash environment, Select Copy to copy the blocks of code, paste it into the Cloud Shell, and press Enter to run it.
Sign in to Azure
Cloud Shell is automatically authenticated under the initial account signed-in with. Use the following script to sign in using a different subscription, replacing
<Subscription ID> with your Azure Subscription ID. If you don't have an Azure subscription, create an Azure free account before you begin.
subscription="<subscriptionId>" # add subscription here az account set -s $subscription # ...or use 'az login'
Run the script
# Function app and storage account names must be unique. # Variable block let "randomIdentifier=$RANDOM*$RANDOM" location="eastus" resourceGroup="msdocs-azure-functions-rg-$randomIdentifier" tag="create-function-app-consumption" storage="msdocsaccount$randomIdentifier" functionApp="msdocs-serverless-function-$randomIdentifier" skuStorage="Standard_LRS" functionsVersion="4" # Create a resource group echo "Creating $resourceGroup in "$location"..." az group create --name $resourceGroup --location "$location" --tags $tag # Create an Azure storage account in the resource group. echo "Creating $storage" az storage account create --name $storage --location "$location" --resource-group $resourceGroup --sku $skuStorage # Create a serverless function app in the resource group. echo "Creating $functionApp" az functionapp create --name $functionApp --storage-account $storage --consumption-plan-location "$location" --resource-group $resourceGroup --functions-version $functionsVersion
Clean up resources
Use the following command to remove the resource group and all resources associated with it using the az group delete command - unless you have an ongoing need for these resources. Some of these resources may take a while to create, as well as to delete.
az group delete --name $resourceGroup
Each command in the table links to command specific documentation. This script uses the following commands:
|az group create||Creates a resource group in which all resources are stored.|
|az storage account create||Creates an Azure Storage account.|
|az functionapp create||Creates a function app.|
