I have a simple nodeJs app which is uses express frame work. I can successfully run this app inside a docker container.
I need to debug this app remotely from VS code how to do that.
the following steps I took to debug remotely inside a
simple node app.js
var express = require('express');
var app = express();
var fs = require('fs')
var logger = fs.createWriteStream('log.txt', { flags: 'a' })
app.get('/', function(reg, res){
res.send('Home page ' + reg.params.id);
});
app.get('/:id', function(reg, res){
if(reg.params.id != 'favicon.ico')
logger.write( ' ' + reg.params.id);
res.send('Home page ' + reg.params.id);
});
app.listen(3000, function(){
console.log('A test server is running');
})
VScode launch.json
{
"type": "node",
"request": "attach",
"name": "Attach to Process",
"port": 5858,
"address": "192.168.1.10",
"restart": false,
"sourceMaps": false,
"localRoot": "${workspaceRoot}/",
"remoteRoot": "/app/"
}
Dockerfile
FROM node:7.2.0-alpine
RUN mkdir /app
WORKDIR /app
COPY . /app
RUN npm install
WORKDIR /app/src
EXPOSE 8080
EXPOSE 5858
CMD ["node","--debug-brk=5858","app.js"]
docker build command
docker build -t remotedebug .
docker run command
docker run --rm --name test -p8080:3000 -p5858:5858 remotedebug
after running the docker it console outputs a message
Debugger listening on 127.0.0.1:5858
but I cant access the node app from localhost:8080 and cannot debug from VScode.
