在 Azure 应用服务中利用 NodeJ 的多核应用服务计划 (Windows)

Question

我创建了一个 nodeJs 应用程序，并已使用 Azure Devops (VSTS) 将其部署到 Azure AppService。
我必须指定 Web.config 来运行我的节点应用程序（否则 Azure AppService 应用程序不会响应）。
Web.config 文件如下所示。
问题是我不知道配置是在多核机器上运行单个进程还是多个进程？ 至少我在微软网站上的文档中没有看到。
如何指示 Azure AppService 使用所有内核？
我知道 pm2 npm 模块并且可以使用它，事实上我正在本地机器上使用它。
但是如何让 Azure 使用它呢？
如何告诉 Web.config 使用 pm2？
AppService 的最佳实践有一个文档，但它指示仅将 pm2 用于基于 Linux 的 应用服务计划 而不是 Windows。

      You can control how Node is hosted within IIS using the following options:
        * watchedFiles: semi-colon separated list of files that will be watched for changes to restart the server
        * node_env: will be propagated to node as NODE_ENV environment variable
        * debuggingEnabled - controls whether the built-in debugger is enabled

查看您的 web.config 文件：

如果你点击那里提供的链接，你会看到你可以设置这个：

• nodeProcessCountPerApplication - IIS 将为每个应用程序启动的 node.exe 进程数； 将此值设置为 0 会导致为机器上的每个处理器创建一个 node.exe 进程

所以：

<iisnode nodeProcessCountPerApplication="0"/>
