docker - 在 Windows 中使用 docker-compose 创建挂载源路径时出错

Question

我正在尝试通过对每个应用进行泊坞化并使用 docker-compose 来泊坞化我的 React-Flask 应用程序把它们放在一起。

这里Dockerfile每个应用程序的 s 看起来像:

React - 前端

FROM node:latest

WORKDIR /frontend/

ENV PATH /frontend/node_modules/.bin:$PATH

COPY package.json /frontend/package.json
COPY . /frontend/
RUN npm install --silent
RUN npm install react-scripts@3.0.1 -g --silent

CMD ["npm", "run", "start"]

Flask - 后端

#Using ubuntu as our base
FROM ubuntu:latest

#Install commands in ubuntu, including pymongo for DB handling
RUN apt-get update -y
RUN apt-get install -y python-pip python-dev build-essential
RUN python -m pip install pymongo[srv]

#Unsure of COPY command's purpose, but WORKDIR points to /backend
COPY . /backend
WORKDIR /backend/

RUN pip install -r requirements.txt

#Run order for starting up the backend
ENTRYPOINT ["python"]
CMD ["app.py"]

当我只使用 docker build 时，它们中的每一个都可以正常工作和 docker up .我已经检查过它们在构建和独立运行时工作正常。然而，当我 docker-compose up docker-compose.yml看起来像

# Docker Compose
version: '3.7'

services:
  frontend:
    container_name: frontend
    build:
      context: frontend
      dockerfile: Dockerfile
    ports:
      - "3000:3000"
    volumes:
      - '.:/frontend'
      - '/frontend/node_modules'
  backend:
    build: ./backend
    ports:
      - "5000:5000"
    volumes:
       - .:/code

给我下面的错误

Starting frontend                ... error
Starting dashboard_backend_1 ...

ERROR: for frontend  Cannot start service sit-frontend: error while creating mount source path '/host_mnt/c/Users/myid/DeskStarting dashboard_backend_1 ... error

ERROR: for dashboard_backend_1  Cannot start service backend: error while creating mount source path '/host_mnt/c/Users/myid/Desktop/dashboard': mkdir /host_mnt/c: file exists

ERROR: for frontend  Cannot start service frontend: error while creating mount source path '/host_mnt/c/Users/myid/Desktop/dashboard': mkdir /host_mnt/c: file exists

ERROR: for backend  Cannot start service backend: error while creating mount source path '/host_mnt/c/Users/myid/Desktop/dashboard': mkdir /host_mnt/c: file exists
ERROR: Encountered errors while bringing up the project.

这是因为我使用的是 Windows 吗？可能是什么问题？提前致谢。

对我来说，唯一有效的方法是重新启动 Docker 守护进程
