使用 PowerShell 在 Azure 中创建函数应用资源
本文中的 Azure PowerShell 示例脚本创建在 Azure 中托管函数所需的函数应用和其他资源。 函数应用提供执行函数的执行上下文。 在函数应用中运行的所有函数共享相同的资源和连接，它们一同缩放。
创建资源后，可以将项目文件部署到新的函数应用。 如需了解详细信息，请参阅部署方法。
每个函数应用都需要用 PowerShell 脚本创建以下资源：
| 资源 | cmdlet | 说明 |
|---|---|---|
| 资源组 | New-AzResourceGroup | 创建一个在其中创建函数应用的资源组。 |
| 存储帐户 | New-AzStorageAccount | 创建函数应用使用的存储帐户。 存储帐户名称必须为 3 到 24 个字符，并且只能包含数字和小写字母。 也可使用现有帐户，但该帐户必须符合存储帐户要求。 |
| 应用服务计划 | New-AzFunctionAppPlan | 显示创建定义如何将资源分配给函数应用的托管计划。 仅在高级或专用计划中托管时使用。 在无服务器消耗计划中托管时，不会使用此 cmdlet，因为运行New-AzFunctionApp时会创建消耗计划。 有关详细信息，请参阅 Azure Functions 托管选项。 |
| 函数应用 | New-AzFunctionApp | 使用所需资源创建函数应用。 -Name参数必须是所有 Azure 应用服务的全局唯一名称。 -Name中的有效字符为a-z（不区分大小写）、0-9和-。 多数示例可创建支持 C# 函数的函数应用。 可通过-Runtime参数修改语言，支持的值包括DotNet、Java、Node、PowerShell和Python。 用-RuntimeVersion选择特定的语言版本。 |
本文包含以下示例：
- 为 C# 创建无服务器函数应用
- 为 Python 创建无服务器函数应用
- 在高级计划中创建可缩放的函数应用
- 在专用计划中创建函数应用
- 创建连接到指定存储的函数应用
- 创建连接到 Azure Cosmos DB 的函数应用
- 创建可持续部署的函数应用
- 创建无服务器 Python 函数应用和装载文件共享
先决条件
- 如果选择在本地使用 Azure PowerShell：
- 安装最新版本的 Az PowerShell 模块。
- 使用 Connect-AzAccount -Environment AzureChinaCloud cmdlet 连接到 Azure 帐户。
如果没有 Azure 订阅，可在开始前创建一个试用帐户。

仅 Linux 支持装载的文件共享。 详细信息请参阅装载文件共享。
清理资源
在前面的步骤中，你在资源组中创建了 Azure 资源。 如果你认为将来不再需要这些资源，请运行以下 PowerShell 命令删除资源组：
Remove-AzResourceGroup -Name myResourceGroup
此命令可能需要花费一点时间运行。
