powershell - VSTS - 在发布期间删除以前的部署

Question

我正在从事一个 Azure 项目，该项目只能使用 Visual Studio CI 中的 ARM 模板进行部署，并且我们只有 Azure 门户的读取访问权限。

目前我收到以下错误，并且无法发布。我也无法从 Portal 中删除部署，因为我只有配置构建和发布阶段的权限，我想知道是否可以创建任何阶段来删除以前的部署。

到目前为止，我尝试了一些方法，例如使用内联 PowerShell 命令 Remove-AzureRmResourceGroupDeployment ，在资源部署阶段之前删除 Microsoft.Resouces/deployments 类型的资源组，但没有他们中的一些人工作了。

[error]Creating the deployment 'azuredeploy-2017721-715' would exceed the quota of '800'. The current deployment count is '800', please delete some deployments before creating a new one. Please see https://aka.ms/arm-deploy for usage details.

这是一个允许您以并行方式删除此类部署的脚本。您还可以将其用于 Azure DevOps 中的 Azure PowerShell 任务。如果您有有关身份验证的问题，请查看此处:Azure credentials have not been set up or have expired, please run Connect-AzAccount
