Question

我尝试使用以下启动命令，并且都成功启动了_default_docker.log中报告的应用程序，但是应用程序服务正在停止容器，因为端口8080的HTTP ping无法获得响应。

pm2 start ecosystem.config.js 
pm2 start npm -- run serve:ssr 4000

ecosystem.config.js文件-在本地运行良好，并在端口8080上成功启动了Web应用程序，并且我已将该文件上传到应用程序服务中的./site/wwwroot/文件夹中。

module.exports = {
  apps : [{
    name: 'ssrapp',
    script: './dist/server/',
    instances: 1,
    autorestart: true,
    watch: false,
    max_memory_restart: '2G'
  }]
};

* _ default_docker.log

我尝试在App Service应用程序设置中设置以下设置（有关这些文档很难获得且相互矛盾），但它们似乎没有任何区别：

端口：8080

WEBSITES_PORT：8080

CONTAINER_AVAILABILITY_CHECK_MODE：仅报告

WEBSITES_CONTAINER_START_TIME_LIMIT：1800

注意：使用启动命令“ npm run serve：ssr”可以在App Service中正常启动节点应用程序，但是我想通过pm2来启动它，以利用监视和重新启动功能。

App Service环境似乎正在停止容器，因为它在5秒内没有响应HTTP ping，但是我找不到任何方法来禁用它以确认这是实际问题。

Answer 1

您的-p 8080:8080命令没有公开端口8080。您只有将容器端口44692公开为端口8081。您可以在日志中以-p 8080:8081看到它。

尝试将其添加到docker run命令行：

-p 8080

如果这不起作用，请尝试{{1}}甚至尝试{{1}}。

Answer 2

以下注释中的

Architect Jamie建议解决了该问题，需要--no-daemon参数。谢谢！

当容器未响应端口8080上的ping操作时，Azure App Service上具有pm2的node.js应用程序失败
