azure-devops - 重新部署Azure Functions ARM模板会删除我发布的函数

Question

我有一个由ARM模板使用Azure DevOps管道部署的Azure Functions(2.0)实例。我有另一个管道，该管道通过zip部署将功能应用程序部署到实例。这几乎可以完美地工作，但是，如果我将基础结构功能部署为代码，然后部署应用程序，然后将基础结构重新部署为代码，则我的功能应用程序将被删除，所有功能都将消失。我正在使用增量部署，所以我想知道为什么要这样做。关于它为什么会这样或如何进行故障排除的任何想法？

我已经在下面复制了资源组部署脚本和ARM模板。

New-AzureRmResourceGroupDeployment -Name ((Get-ChildItem $TemplateFile).BaseName + '-' + ((Get-Date).ToUniversalTime()).ToString('MMdd-HHmm')) `
                                   -ResourceGroupName $ResourceGroupName `
                                   -TemplateFile $TemplateFile `
                                   -TemplateParameterFile $TemplateParametersFile `
                                   -Mode Incremental `
                                   @OptionalParameters `
                                   -Force -Verbose `
                                   -AdminsGroup $AdminsGroup `
                                   -AdminsGroupObjectId $AdminsGroupObjectId `
                                   -ErrorVariable ErrorMessages

将此应用设置添加到您的模板中:

{ "name": "WEBSITE_RUN_FROM_PACKAGE", "value": "1" }

如果存在此设置，则只能从zip文件运行功能，并且重新部署没有此设置的模板将删除该设置的现有值(如果有)。
