如何让我的 Next.js 应用程序在 Azure 应用程序服务 运行 ubuntu-latest 中启动?

How do I get my Next.js app to start in an Azure App Service running ubuntu-latest?

我正在尝试在 Azure 上部署我的 Next.js (SSR)。

我有一个发布整个根文件夹的构建管道(不仅仅是静态应用程序的 .next 文件夹)

trigger:
  - main

pool:
  vmImage: "ubuntu-latest"

# Set variables
variables:
  directory: .

steps:
  - task: NodeTool@0
    inputs:
      versionSpec: "16.x"
    displayName: "Install Node.js"

  - script: yarn
    displayName: "Install dependencies"
    workingDirectory: $(directory)
    
  - task: Cache@2
    displayName: 'Cache .next/cache'
    inputs:
      key: next | $(Agent.OS) | yarn.lock
      path: '$(System.DefaultWorkingDirectory)/.next/cache'

  - script: yarn build
    displayName: "Build for production"
    workingDirectory: $(directory)

  - task: CopyFiles@2
    displayName: "Copy files"
    inputs:
      sourceFolder: "$(directory)"
      Contents: "**/*"
      TargetFolder: "$(Build.ArtifactStagingDirectory)"
      cleanTargetFolder: true

  - task: ArchiveFiles@2
    displayName: "Archive files"
    inputs:
      rootFolderOrFile: "$(Build.ArtifactStagingDirectory)"
      includeRootFolder: false
      archiveType: zip
      archiveFile: $(Build.ArtifactStagingDirectory)/$(Build.BuildId).zip
      replaceExistingArchive: true

  - task: PublishBuildArtifacts@1
    displayName: "Publish build artifacts"
    inputs:
      pathtoPublish: $(Build.ArtifactStagingDirectory)/$(Build.BuildId).zip

我在项目根文件夹中还有一个文件 ecosystem.config.js,其中包含内容(如 this answer 中所述)

module.exports = {
  apps: [
    {
      name: "app-name",
      script: "./node_modules/.bin/next",
      args: "start -p " + (process.env.PORT || 3000),
      watch: false,
      autorestart: true,
    },
  ],
};

如前所述,构建管道将整个根文件夹发布为发布管道的 .zip 工件。

我有一个发布管道,可以将项目部署到应用服务并运行启动命令(来自 same answer as before and Microsoft docs

pm2 start /home/site/wwwroot/ecosystem.config.js --no-daemon

package.json 脚本部分

"scripts": {
  "dev": "next dev",
  "build": "next build",
  "start": "next start",
  "lint": "next lint"
}

我可以看到构建和发布管道都已成功完成,我可以看到根项目文件夹中的文件位于 /home/site/wwwroot,但是当我访问该站点时,我得到的是

通往诊断资源的 link 并没有提供太多的洞察力,但如果我检查应用服务中 docker 容器的日志,我会看到

有人知道如何从这里开始吗?

提前致谢!

使用 Kudu 检查您的 wwwroot 目录(开发工具 -> 高级工具)。默认情况下,Azure Devops 发布管道未复制 files/folders 从“.”开始,因此文件夹“/node_modules/.bin/”可能尚未复制到 Azure App Service

我通过将 ecosystem.config.js 中的 start-up 脚本更改为

解决了这个问题
./node_modules/next/dist/bin/next

而不是

./node_modules/.bin/next

我的新ecosystem.config.js

module.exports = {
  apps: [
    {
      name: "app-name",
      script: "./node_modules/next/dist/bin/next",
      args: "start -p " + (process.env.PORT || 3000),
      watch: false,
      autorestart: true,
    },
  ],
};
