I try to start simple nodejs server inside Docker container and debug it with chrome://inspect or WebStorm. Debugging port 9229 is binded but inspection not works. On the other hand when I run same code without docker i can inspect it in chrome://inspect and in WebStorm both well.
Can anybody explain me why Chrome can't inspect nodejs code in Docker container???
Dockerfile
FROM node:8.2.1-alpine
WORKDIR /code
COPY package.json /code/package.json
RUN npm install && npm ls
RUN mv /code/node_modules /node_modules
COPY . /code
EXPOSE 8000
EXPOSE 9229
CMD ["npm", "run", "start"]
alexey@home:~/app$ docker run -p 9229:9229 -p 8000:8000 node-dev
npm info it worked if it ends with ok
npm info using npm@5.3.0
npm info using node@v8.2.1
npm info lifecycle @~prestart: @
npm info lifecycle @~start: @
> @ start /code
> node --inspect app
