节点。当容器未响应端口8080上的ping时，Azure应用程序服务上带有pm2的js应用程序失败

Question

我尝试过使用以下启动命令，两个命令都成功地启动了应用程序，正如_default_docker中报告的那样。但应用程序服务正在停止容器，因为端口8080的HTTP ping没有得到响应。

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

生态系统配置。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，我已将该文件上载到/应用程序服务中的site/wwwroot/文件夹。

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

我曾尝试在App Service应用程序设置中设置以下设置（关于这些设置的文档很难找到，并且相互矛盾），但它们似乎没有任何区别：

端口：8080

网址:8080

容器可用性检查模式：仅报告

网站\u容器\u开始\u时间\u限制：1800

注意：节点应用程序启动罚款在应用程序服务与启动命令"npm运行服务：ssr"，但我想启动它通过pm2利用监视和重启功能。

看起来应用服务环境正在停止容器，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来确认这是实际问题。

Answer 1

您的docker run命令未公开端口8080。您只有容器端口44692作为端口8081公开。您可以在日志中看到这一点，如-p 44692:8081。

尝试将其添加到docker run命令行：

-p 8080:8080

如果这不起作用，请尝试-p8080:8081，或者干脆-p8080。

架构师Jamie在下面的评论中建议解决了这个问题，不需要守护进程参数。非常感谢。
