Question

我努力让我的node.js容器在ECS上运行。当我使用docker compose在本地运行它时运行正常，但在ECS上它运行2-3分钟并处理几个连接（来自负载均衡器的2-3次运行状况检查），然后关闭。我无法解决原因。

我的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中 -

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

在我的docker-compose.yml中，我使用nodemon -

运行

node:
  ...
  command: nodemon

在我的cloudWatch日志中，我可以看到一切开始 -

14:20:24  npm info lifecycle my_app@1.0.0~start: my_app@1.0.0

然后我看到健康状况检查请求（全部使用http 200＆＃39; s），稍后它会全部结束 -

14:23:00  npm info lifecycle mapov_reporting@1.0.0~poststart: mapov_reporting@1.0.0
14:23:00  npm info ok

我已尝试在forever-monitor中包装我的start.js脚本，但这似乎没有任何区别。

更新

我的ECS任务定义 -

任务都以状态Task failed ELB health checks in (target-group ...停止。健康检查在开始失败之前通过2到3次。除了日志中的http 200之外，没有任何记录。

Answer 1

我使用的是旧版本的mongo驱动程序~2.0，并保持与多个数据库的连接。当我升级驱动程序时，问题就消失了。

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

我只能假设驱动程序中存在错误。
