Azure Linux WebApp 上的 ASP.NET Core NodeServices [英] ASP.NET Core NodeServices on Azure Linux WebApp

问题描述

我习惯于在 Windows 上发布 Azure WebApp，但现在我尝试将 ASP.NET Core 3(带有 NodeServices)部署到 Linux WebApp，我收到以下错误消息:

I am used to publish Azure WebApps on Windows but now I am trying to deploy an ASP.NET Core 3 (with NodeServices) to a Linux WebApp and I am receiving the following error message:

InvalidOperationException:无法启动节点进程.要解决这个问题:.

[1] 确保 Node.js 已安装并且可以在 PATH 目录之一中找到.当前 PATH 环境变量是:/opt/dotnetcore-tools:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/home/site/wwwroot确保 Node 可执行文件位于这些目录之一中，或更新您的 PATH.

[1] Ensure that Node.js is installed and can be found in one of the PATH directories. Current PATH enviroment variable is: /opt/dotnetcore-tools:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/home/site/wwwroot Make sure the Node executable is in one of those directories, or update your PATH.

在 Windows WebApps 上，我有很多其他应用程序，一切都很好.

On Windows WebApps I have a lot of other apps and all are fine.

在 Kudu 上，我输入了 node -v，输出为 v12.13.0.

On Kudu I typed node -v and the output was v12.13.0.

谁能帮帮我?

非常感谢.

推荐答案

经过长期研究和微软工程师的协助https://github.com/caroe2014 这是最终答案的三个步骤:

After a long research and the assistance of Microsoft's Engineer https://github.com/caroe2014 this is the three steps final answer:

1) Startup.cs

1) Startup.cs

    services.AddNodeServices(options =>
        {
          if (RuntimeInformation.IsOSPlatform(OSPlatform.Linux))
          {
            options.ProjectPath = Path.GetFullPath("/home/site/wwwroot");
          }
        }
      );

2) 我发现容器中不存在 Node，因此在启动应用程序之前必须有一个脚本来安装和启动它.所以我有这个 start1.cs 文件:

2) And what I found is Node is not present in the container so it is necessary to have a script to install and start it before starting the app itself. So I have this start1.cs file:

#!/bin/bash

apt-get install curl
curl -sL https://deb.nodesource.com/setup_12.x | bash
apt-get install -y nodejs

set -e
export PORT=8080
export ASPNETCORE_URLS=http://*:$PORT
dotnet "Web.Identity.dll"

Web.Identity.dll 是我的应用程序的 dll.

Where Web.Identity.dll is the dll of my app.

3) 将启动命令设置为 /home/site/wwwroot/start1.sh(在 Azure 门户 - 应用服务配置 - 或 Azure DevOps 上).

3) Set startup command to /home/site/wwwroot/start1.sh (On Azure Portal - App service Configuration - or Azure DevOps).

就是这样.
