Expressjs应用程序从Docker中的PM2开始，随着SIGINT而死

我有一个非常简单的Expressjs应用程序 – 基本上是一个单一的职位电话库封装。

这里是app.js内容：

 var compression = require('compression'); var express = require('express'); var path = require('path'); var bodyParser = require('body-parser'); var convert = require('./routes/convert'); var app = express(); app.use(bodyParser.json()); app.use(bodyParser.urlencoded({ extended: false })); app.use(compression()); app.use('/', convert); module.exports = app; 

然后，我创build了Dockerfile来容器化应用程序：

 FROM mhart/alpine-node WORKDIR /src COPY package.json ./ COPY app.js ./ ADD routes/ ./routes/ ADD bin/ ./bin/ RUN npm i RUN npm install -g pm2@2.4.0 EXPOSE 3000 CMD ["pm2-docker", "app.js"] 

当我尝试提出这个问题时（这是DEBUG = express：*）

看起来像过程死亡，然后始终重新启动。 我不是一个Node开发者，只需要这个工作，期待任何的build议和帮助。

谢谢。
