如何在不退出的情况下在AWS ECS上运行节点容器

我正努力让我的node.js容器在ECS上运行。当我使用docker撰写本地文件时，它运行良好，但在ECS上运行2-3分钟并处理几个连接（负载均衡器进行2-3次健康检查），然后关闭。我无法弄清楚为什么。如何在不退出的情况下在AWS ECS上运行节点容器

我Dockerfile -

FROM node:6.10 

RUN npm install -g nodemon \ 
    && npm install forever-monitor \ 
    winston \ 
    express-winston 

RUN mkdir -p /usr/src/app 
WORKDIR /usr/src/app 

COPY package.json /usr/src/app/ 
RUN npm install 

COPY . /usr/src/app 

EXPOSE 3000 

CMD [ "npm", "start" ]

然后在我的package.json -

{ 
    ... 
    "main": "forever.js", 
    "dependencies": { 
    "mongodb": "~2.0", 
    "abbajs": ">=0.1.4", 
    "express": ">=4.15.2" 
    } 
    ... 
}

在我的码头工人，compose.yml我nodemon运行 -

node: 
    ... 
    command: nodemon

在我的CloudWatch日志我可以看到一切都开始 -

14:20:24 npm info lifecycle [email protected]~start: [email protected]

然后我看到了健康检查的要求（所有HTTP 200的），那么稍后这一切包扎 -

14:23:00 npm info lifecycle [email protected]~poststart: [email protected] 
14:23:00 npm info ok

我已经试过包装我start.js脚本forever-monitor，但似乎没有任何区别。

UPDATE

我ECS任务定义 -

您是否尝试过使用与您的ECS任务配置完全相同的命令在本地运行它？ –

谢谢@PaulBecotte - 是的，我现在就试过 - 它已经跑了5分钟，没有问题。 –

你能分享你的ECS任务定义吗？ –

我使用的是mongo驱动程序的旧版本~2.0，并保持与多个数据库的连接。当我升级司机时，问题就消失了。

"dependencies": { 
    "mongodb": ">=2.2" 
    }

我只能假设驱动程序中有一个错误。
