Docker不是挂载目录吗？ “OCI 运行时创建失败：container_linux.go:346：没有这样的文件或目录：未知”

Question

On my Windows 10 Home computer with Docker Toolbox, Docker is having trouble mounting the drives. I've already run dos2unix on the entrypoint.sh file.

The full error is as such:

ERROR: for users  Cannot start service users: OCI runtime create failed: container_linux.go:346: starting container process caused "exec: \"/usr/src/app/entrypoint.sh\": stat /usr/src/app/entrypoint.sh: no such file or directory": unknown

My docker-compose.yml:

version: '3.7'

services:

  users:
    build:
      context: ./services/users
      dockerfile: Dockerfile
    entrypoint: ['/usr/src/app/entrypoint.sh']
    volumes:
      - './services/users:/usr/src/app'
    ports:
      - 5001:5000
    environment:
      - FLASK_ENV=development
      - APP_SETTINGS=project.config.DevelopmentConfig
      - DATABASE_URL=postgresql://postgres:postgres@users-db:5432/users_dev
      - DATABASE_TEST_URL=postgresql://postgres:postgres@users-db:5432/users_test
    depends_on:
      - users-db

Curiously, when I comment out the "volumes" section, it works. But I want to be able to mount volumes in the future.

Directory structure can be seen as such:

                    test_users_unit.py
                    __init__.py

I have added the D:\flask-react-auth\ to the 'Shared Folders' on virtualbox as well.

The answer seems obvious to me:

When you run the code as is * it mounts the current working directory to '/usr/src/app'. * The current working directory does not have a file 'entrypoint.sh'. * It tries to run '/usr/src/app/entrypoint.sh' but it is not there so it fails.

When you comment out that volume mount * I assume the image already has '/usr/src/app/entrypoint.sh' so it just works.

I think you probably should change the mounting code from

    volumes:
      - '.:/usr/src/app'

to

    volumes:
      - './services/users:/usr/src/app'
