Docker isn't mounting the directory? "OCI runtime create failed: container_linux.go:346: no such file or directory: unknown" - docker

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:
D:\flask-react-auth
│ .gitignore
│ .gitlab-ci.yml
│ docker-compose.yml
│ README.md
│ release.sh
│
└───services
│
└───users
│ .coveragerc
│ .dockerignore
│ Dockerfile
│ Dockerfile.prod
│ entrypoint.sh
│ manage.py
│ requirements-dev.txt
│ requirements.txt
│ setup.cfg
│ tree.txt
│
└───project
│ config.py
│ __init__.py
│
├───api
│ │ ping.py
│ │ __init__.py
│ │
│ └───users
│ admin.py
│ crud.py
│ models.py
│ views.py
│ __init__.py
│
├───db
│ create.sql
│ Dockerfile
│
└───tests
conftest.py
pytest.ini
test_admin.py
test_config.py
test_ping.py
test_users.py
test_users_unit.py
__init__.py
I have added the D:\flask-react-auth\ to the 'Shared Folders' on virtualbox as well.

Answer 1

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'
