当前操作系统无法运行此任务

Question

从Azure DevOps管道中，使用在docker上运行的自托管linux构建代理，我在terraform计划中得到以下错误。我尝试了很多事情，甚至从构建代理的bash shell运行步骤：效果很好。

您有什么建议吗？

管道在“地形计划”中失败。这是yml：

variables:
  env: 'environment'

steps:

  displayName: 'Terraform plan'

构建代理是一个docker容器，使用以下dockerfile构建

正如您所说，是的，Terraform计划可以兼容，包括linux，windows和MacOS。但是现在，您面临的问题是您正在使用的扩展名和任务，该任务和扩展名和任务Run Terraform仅可以在Windows上安装的代理中执行。您可以查看其文档以了解以下信息：Getting started with Terraform on Windows and Azure。

还有另外一个由我们的Microsoft DevLabs和个人开发人员创建的扩展：Terraform和Terraform Build & Release Tasks。这两个扩展中的任务都可以在Windows，Linux和macOS中进行编译。

您最好更改为使用这两个扩展中的任务。
