      - CHOKIDAR_USEPOLLING=true
    ports:
      - 3001:3000
    volumes:

RUN touch /home/node/.bashrc | echo "PS1='\w\$ '" >> /home/node/.bashrc

RUN npm config set cache /home/node/app/.npm-cache --global

WORKDIR /home/node/app

COPY --chown=node:node . ./

USER node

and entrypoint.sh

#!/bin/bash

npm config set cache /home/node/app/.npm-cache --global

I had suspected it was in relation to the node user, but I tested it without and it was not i got this with docker-compose log.

Your docker-compose.yml says

volumes:
      - .:/home/node/app

Remove these two lines, build application locally (without Docker), and only build the Docker image when you are deploying it.

for further explanation refer this docker-compose fails to start with npm ERR! enoent ENOENT: no such file or directory, open '/usr/src/app/package.json'
