使用 ARM 模板启用 Azure VM 扩展

本文介绍如何使用 Azure 资源管理器模板(ARM 模板)部署已启用 Azure Arc 的服务器支持的 Azure VM 扩展。

VM 扩展可添加到 Azure Resource Manager 模板,并在部署模板的过程中执行。 使用已启用 Azure Arc 的服务器支持的 VM 扩展,可以通过 Azure PowerShell 在 Linux 或 Windows 计算机上部署支持的 VM 扩展。 下面的每个示例都包含模板文件和参数文件,其中包含要提供给模板的示例值。

注意

虽然可以将多个扩展分批在一起并进行处理,但它们是以串行方式安装的。 第一个扩展安装完成后,将尝试安装下一个扩展。

注意

已启用 Azure Arc 的服务器不支持管理 VM 扩展,也不支持将 VM 扩展部署到 Azure 虚拟机。 对于 Azure VM,请查看下面的 VM 扩展概述一文。

部署 Log Analytics VM 扩展

若要轻松部署 Log Analytics 代理,可以使用以下示例在 Windows 或 Linux 上安装代理。

适用于 Linux 的模板文件

        }
    },
    "resources": [
        {

                    "workspaceKey": "[parameters('workspaceKey')]"
                }
            }
        }
    ]
}

适用于 Windows 的模板文件

{
    "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json",
    "contentVersion": "1.0.0.0",
    "parameters": {

        }
    },
    "resources": [
        {

                "settings": {
                    "workspaceId": "[parameters('workspaceId')]"
                },
                "protectedSettings": {
                    "workspaceKey": "[parameters('workspaceKey')]"
                }
            }
        }
    ]
}

参数文件

{
    "$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentParameters.json#",
    "contentVersion": "1.0.0.0",
    "parameters": {
        "vmName": {
            "value": "<vmName>"
        },
        "location": {
            "value": "<region>"
        },
        "workspaceId": {
            "value": "<MyWorkspaceID>"
        },
        "workspaceKey": {
            "value": "<MyWorkspaceKey>"
        }
    }
}

将模板和参数文件保存到磁盘,然后使用部署的适当值编辑参数文件。 然后,可以使用以下命令在资源组中所有连接的计算机上安装该扩展。 该命令使用 TemplateFile 参数来指定模板,并使用 TemplateParameterFile 参数指定包含参数和参数值的文件 。

New-AzResourceGroupDeployment -ResourceGroupName "ContosoEngineering" -TemplateFile "D:\Azure\Templates\LogAnalyticsAgent.json" -TemplateParameterFile "D:\Azure\Templates\LogAnalyticsAgentParms.json"

部署自定义脚本扩展

为了使用自定义脚本扩展,本文提供了在 Windows 和 Linux 上运行的以下示例。 如果不熟悉自定义脚本扩展,请参阅适用于 Windows 的自定义脚本扩展适用于 Linux 的自定义脚本扩展。 对混合计算机使用此扩展时,有几个不同的特征需要了解:

  • Azure VM 自定义脚本扩展的支持的操作系统列表不适用于已启用 Azure Arc 的服务器。 可在此处找到已启用 Azure Arc 的服务器支持的 OS 列表。

  • 有关 Azure 虚拟机规模集或经典 VM 的配置详细信息不适用。

  • 如果计算机需要在外部下载脚本并且只能通过代理服务器进行通信,则需要配置已连接的计算机代理设置代理服务器环境变量。

自定义脚本扩展配置指定脚本位置和要运行的命令等设置。 此配置在下面为 Linux 和 Windows 混合计算机提供的 Azure 资源管理器模板中指定。

注意

观察到的证书 URL 的格式应为 https://myVaultName.vault.azure.cn/secrets/myCertName

这是因为 /secrets 路径将返回包含私钥的完整证书,而 /certificates 路径不会。 有关证书的详细信息可在此处找到:密钥保管库证书

模板部署

将模板文件保存到磁盘。 然后,可以通过以下命令将扩展部署到已连接的计算机。

注意

VM 扩展需要分配有系统分配的标识,才能向 Key Vault 进行身份验证。 对于已启用 Azure Arc 的 Windows 和 Linux 服务器,请参阅如何使用托管标识对密钥保管库进行身份验证
