快速入门：使用 ARM 模板创建和部署 Azure Functions 资源

Artículo
07/10/2024

在本文中，你将组合使用 Azure Functions 和 Azure 资源管理器模板（ARM 模板）在 Azure 中创建函数应用和相关资源。函数应用为函数代码执行提供了执行上下文。

完成本快速入门会从你的 Azure 帐户中扣取最多几美分的费用。

Azure 资源管理器模板是定义项目基础结构和配置的 JavaScript 对象表示法 (JSON) 文件。模板使用声明性语法。你可以在不编写用于创建部署的编程命令序列的情况下，描述预期部署。

如果你的环境满足先决条件，并且你熟悉如何使用 ARM 模板，请选择“部署到 Azure”按钮。 Azure 门户中会打开模板。

创建函数应用后，你可以将 Azure Functions 项目代码部署到该应用。

先决条件

Azure 帐户

在开始之前，必须拥有一个包含有效订阅的 Azure 帐户。创建帐户。

}

此模板会创建下面 4 个 Azure 资源：

Microsoft.Storage/storageAccounts：创建 Functions 需要的 Azure 存储帐户。
Microsoft.Web/serverfarms：为函数应用创建无服务器的消耗托管计划。
Microsoft.Web/sites：创建函数应用。
microsoft.insights/components：创建用于监视的 Application Insights 实例。

重要

存储帐户用于存储重要的应用数据，有时包括应用程序代码本身。应限制其他应用和用户对存储帐户的访问。

read -p "Enter a resource group name that is used for generating resource names:" resourceGroupName &&
read -p "Enter the location (like 'chinanorth2' or 'chinaeast2'):" location &&
templateUri="https://raw.githubusercontent.com/Azure/azure-quickstart-templates/master/quickstarts/microsoft.web/function-app-create-dynamic/azuredeploy.json" &&
az group create --name $resourceGroupName --location "$location" &&
az deployment group create --resource-group $resourceGroupName --template-uri  $templateUri &&
echo "Press [ENTER] to continue ..." &&
read

$resourceGroupName = Read-Host -Prompt "Enter a resource group name that is used for generating resource names"
$location = Read-Host -Prompt "Enter the location (like 'chinanorth2' or 'chinaeast2')"
$templateUri = "https://raw.githubusercontent.com/Azure/azure-quickstart-templates/master/quickstarts/microsoft.web/function-app-create-dynamic/azuredeploy.json"

New-AzResourceGroup -Name $resourceGroupName -Location "$location"
New-AzResourceGroupDeployment -ResourceGroupName $resourceGroupName -TemplateUri $templateUri

Read-Host -Prompt "Press [ENTER] to continue ..."

访问函数应用欢迎页

使用上一验证步骤的输出来检索为函数应用创建的唯一名称。
打开浏览器并输入以下 URL：<https://<appName.chinacloudsites.cn>。请确保将 <\appName> 替换为为函数应用创建的唯一名称。

访问 URL 时，应看到如下所示的页面：

清理资源

若要继续执行下一步并添加 Azure 存储队列输出绑定，请保留到目前为止构建的所有资源。

否则，请使用以下命令删除资源组及其包含的所有资源，以免产生额外的费用。

Azure CLI
Azure PowerShell

az group delete --name <RESOURCE_GROUP_NAME>

Remove-AzResourceGroup -Name <RESOURCE_GROUP_NAME>

将 <RESOURCE_GROUP_NAME> 替换为资源组的名称。

后续步骤

现在，你已在 Azure 中创建了函数应用资源，你可以使用下列工具之一将代码部署到现有应用：
