Question

我正在尝试将.netcore 2.1.5 API部署到Windows 2012 Server R2

当前，我发布的api网站导航至该错误

HTTP Error 502.5 - Process Failure

Common causes of this issue:
The application process failed to start
The application process started but then stopped
The application process started but failed to listen on the configured port

Troubleshooting steps:
Check the system event log for error messages
Enable logging the application process' stdout messages
Attach a debugger to the application process and inspect

在事件日志中，我可以看到

Event 1000, IIS AspNetCore Module
Application 'MACHINE/WEBROOT/APPHOST/MYSITE.COM.AU/MYAPINAME' with physical root 'C:\WebSites\MYSITE.COM.AU\MyApps\MYAPINAME\' failed to start process
commandline '.\dotnet .\mydllname.dll', ErrorCode='0x80004005 : 80008083

来自this question

我看到我可以加入

 <PublishWithAspNetCoreTargetManifest>False</PublishWithAspNetCoreTargetManifest>

在发布配置文件中如果要确保在主机计算机上安装了正确版本的DotNetCore。

但是，如果我想使用Azure Devops，该如何设置？

我尝试在“发布”任务中检查“发布Web项目”

但是我得到一个错误

No web project was found in the repository. Web projects are identified by 
presence of either a web.config file or wwwroot folder in the directory.

找不到与指定模式匹配的项目文件。

依赖项包括

Microsoft.AspNetCore.App 2.1.5

但是我看不到部署有响应内核的dll。

我尝试在计算机上安装dotnet-runtime-2.1.5，该软件是从 the installer site

[更新]

我注意到缺少日志文件夹，所以我手动创建了它

我添加了Eriawan建议的任务 YAML是

    steps:
- task: DotNetCoreInstaller@0
  displayName: 'Use .NET Core sdk 2.1.5'
  inputs:
    version: 2.1.5

我使用YAML创建了新管道

Eriawan有答案。我需要使用YAML管道并在此处获取版本。

Answer 1

为了控制构建以使用特定版本的.NET Core运行时，必须在构建代码之前告诉构建代理安装要使用的.NET Core SDK，并指定要安装的SDK版本。

如果在Azure DevOps Pipelines构建上使用YAML，则可以运行以下任务：DotNetCoreInstaller @ 0并将其版本设置为2.1.403。

该任务必须在任何任务之前运行，最好是第一个要运行的任务。

例如：

- task: DotNetCoreInstaller@0
  inputs:
    version: '2.1.403'

如果使用的是构建定义设计器，请添加“ .NET Core工具安装程序”任务，然后从此处指定要使用的版本。

请查阅MSFT文档上的.NET Core构建示例：

https://docs.microsoft.com/en-us/azure/devops/pipelines/languages/dotnet-core?view=vsts&tabs=yaml#build-environment

更新1 ：

好的，我已经看到您的构建错误。看起来.NET Core安装程序任务的2.1.403的.NET Core SDK的URL地址错误。

您可以改用纯YAML。我将在.NET Core安装程序任务存储库中提交一个错误。同时，请使用完整的YAML。

我已经有一个有效的YAML文件，该文件的示例可以在我自己的存储库中找到。

例如：

https://github.com/RXCommunica/rx-azuredevops-rest/blob/master/azuredevopsrest-ci-vs2017.yml

更新2 ：

我已经为您的YAML添加了评论。 YAML上的.NET Core工具版本不正确。从原始版本更新/更改您的Yaml：

- task: DotNetCoreInstaller@0
  displayName: 'Use .NET Core sdk 2.1.5'
  inputs:
    version: 2.1.5

收件人：

- task: DotNetCoreInstaller@0
  displayName: 'Use .NET Core sdk 2.1.5'
  inputs:
    version: 2.1.403

这很重要，因为.NET Core运行时的版本与实际的SDK工具版本不相同。

请参考此文档以获取工具版本和.NET Core 2.1的相关运行时列表：

https://www.microsoft.com/net/download/dotnet-core/2.1

如何确保正确的DotNet Core包含在构建中？
