docker-compose failed on friend's linux computer-CodePudding

I'm starting to learn Docker, and i'm following this (very) long tutorial: https://www.youtube.com/watch?v=9zUHg7xjIqQ

I have a Dockerfile and a docker-compose.yml .

It work fine on my fine on my machine (we all know this sentence), but when my friend pulled what i've done, he obtains this error message: Error response from daemon: invalid mount config for type "volume": invalid mount path: 'node_back/node_modules' mount path must be absolute

Here are my files:

Dockerfile in node_back/ :


WORKDIR /app

COPY package.json .

RUN npm install

COPY . ./

EXPOSE 3000

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

docker-compose at the root:


services:
  back-container:
    build: ./node_back
    image: back-image:tag
    ports:
      - "3000:3000"
    volumes:
      - ./node_back:/app
      - ./node_back/node_modules
    environment:
      - PORT=3000

I used the command: sudo docker-compose up -d to launch the docker script.

Can somebody explain my error, and why it work on my side?

Thanks!

CodePudding user response：

Because you forgot ':' on volume path line.

./node_back/node_modules

you should be used ':' for separate your local volume and docker volume

./node_back/node_modules:WHERE-YOUR-WANT-DOCKER-PATH
