javascript - Docker container nodejs connection to external mysql fail -

my nodejs application connecting mysql externally, if start interactively docker run -p 49160:8080 -t -i <image>, , run nodejs /src/server.js manually. however, when start daemon docker run -p 49160:8080 -d <image>, fail connect external mysql.

tried docker start <container> , docker exec <container> nodejs /src/server.js, same error.

tried docker start <container>,docker attach <container> ,run nodejs /src/server.js, works.

dockerfile:

from ubuntu re-create . /src run apt-get install nodejs run apt-get install npm run cd /src; npm install expose 8080 cmd ["nodejs","/src/server.js"]

/src/server.js:

var express = require('express'); var mysql = require('mysql'), myconnection = require('express-myconnection'); ... app.use(myconnection(mysql, { ... },'request')); ... app.get('/',function(req,res) { req.getconnection(function(err,connection) { if(err) // giving out err here, fail connect

update:

i found out cause nodejs /src/server.js , cd /src; nodejs server.js former give me connection error , latter works ok

so docker run -p 49160:8080 -d <image> /bin/sh -c "cd /src; nodejs server.js" works

mark ,do have thought ?? still need output of ifconfig? thx

ok, seems problem directory launch command. let's give seek adding in dockerfile before cmd command:

workdir /src

ps no thanks, ifconfig no more needed.

javascript mysql node.js connection docker
