I am a docker beginner and trying to dockerize simple projects as part of my learning journey.. I am trying to dockerize a NestJS project, but the docker-compose up command fails.

My Dockerfile and docker-compose.* files look as below. I have tried various changes to Dockerfile and docker-compose files but with no luck.. Can some spot the issue or something that I am missing.

Dockerfile

FROM node:12.10

RUN mkdir -p /usr/src/app

WORKDIR /usr/src/app

COPY package*.json ./

RUN npm install

COPY . .

RUN npm build

docker-compose.yml

version: '3'
services:
  app:
    build: .
    ports:
      - '8081:8081'

docker-compose.dev.yml

version: '3'
services:
  app:
    command: npm start
    volumes:
      - .:/usr/src/app
    environment:
      - NODE_ENV=development

And, here's the command I run...

docker-compose -f docker-compose.yml -f docker-compose.dev.yml up

The command fails with below error

  • So we know that node_modules is missing... could it be that you are running `npm install` on build and then you're mounting your local directory to the same path – essentially overwriting the entire directory (and removing your node_modules dir)? Try removing your volume mount (lines 5 and 6) from docker-compose.dev.yml then `docker-compose up --build` – Andy Mardell Feb 27 '20 at 21:25

    yeah, that seems to be the problem. Nice catch. Thank you Andy. – Guna Feb 28 '20 at 05:21

Hey i tried this solution and it worded with me, i hope it works with you as well https://stackoverflow.com/a/50454232/13549437

The basic idea is that we are going to invoke the ts-node from node_modules folder rather than from the local /bin folders (the global commands folder).

  1. Install ts-node and typescript npm i ts-node typescript

  2. The start script in the package.json "start": "./node_modules/.bin/ts-node index.ts"

  3. The run script in the docker file RUN npm install
