Error when running node container using docker compose

Question

When running "docker-compose up", I get the following error:

npm info lifecycle server@1.0.0~dev: server@1.0.0

> server@1.0.0 dev /code/app
> nodemon -L ./bin/www --exec babel-node

sh: 0: getcwd() failed: No such file or directory
path.js:1144
      cwd = process.cwd();
                    ^

My dockerfile looks like this:

FROM joakimbeng/node-zeromq

RUN mkdir /code/
RUN mkdir /code/app/
COPY package.json /code/

WORKDIR /code
RUN npm install -g nodemon babel-cli
RUN npm install

WORKDIR /code/app

CMD ["npm", "run", "dev"]

And my service like this:

node:
    build: ./node/
    ports:
      - "3000:3000"
    volumes:
      - ../code:/code/app
    links:
      - mongodb
      - python
    environment:
      - NODE_ENV=dev
      - NODE_PATH=/code/node_modules
      - MONGODB_ADDRESS=mongodb
      - PYTHON_ADDRESS=python

I've tried to delete all containers and images and run the whole thing again, but the same error appears. It seems to build fine when running "docker-compose build".

What I'm trying to accomplish here is: 1. Let the container handle all the dependencies (node modules) 2. Mount my code base to the container 3. Use nodemon for hot reload

I ended up with something similar to what I did initially. Not sure what caused the error in my OP, but the difference seems to be that I mount my dependencies in a different directory.

Dockerfile:

FROM joakimbeng/node-zeromq

RUN mkdir /code/
RUN mkdir /dependencies/
COPY package.json /dependencies/

WORKDIR /dependencies/
RUN npm install -g nodemon babel-cli
npm install

WORKDIR /code/
CMD bash -c "npm run dev"

Service in docker-compose:

  node:
build: ./node/
ports:
  - "3000:3000"
volumes:
  - ../code/:/code
links:
  - mongodb
  - python
environment:
  - NODE_ENV=dev
  - NODE_PATH=/dependencies/node_modules
  - MONGODB_ADDRESS=mongodb
  - PYTHON_ADDRESS=python

This way my dependencies are only installed on build.
