docker-compose 与卷 - package.json 的“没有这样的文件或目录”

Question

I have a Dockerfile and a docker-compose.yml file. Everything works fine until I add the volumes lines to the docker-compose file. When I do add the volumes I get the below error. I am using docker toolbox with Oracle VM VirtualBox on windows 7.

Dockerfile

FROM node:10.16.3

WORKDIR /usr/src/facerecognitionbrain-api

COPY ./ ./

RUN npm install

CMD ["/bin/bash"]

docker-compose.yml

version: '3.7'

services:
 facerecognitionbrain-api:
  container_name: backend
  # image: node:10.16.3
  build: ./
  command: npm start
  working_dir: /usr/src/facerecognitionbrain-api
  ports:
  - "3008:3008"
  volumes:
  - ./:/usr/src/facerecognitionbrain-api

Error

I think you should volume only a sub/directory of your WORKDIR, not the full /usr/src/facerecognitionbrain-api.

Here the volume is created, and then npm tries to read package.json, but docker looks for the file in your volume, which is empty.
