Docker - Python Django error entrypoint.sh: no such file or directory

问题

I follow a tutorial about DRF backend and Docker use for test api.
Link tutorial: https://www.youtube.com/watch?v=tujhGdn1EMI
They were fully setup docker-compose and dockerfile. I am following but got error "exec /code/docker/entrypoints/entrypoint.sh: no such file or directory" on docker desktop.

The docker-compose.yml file:

  1. version: '3.7'
  2. services:
  4.   api:
  5.     build:
  6.       context: ./backend
  7.       dockerfile: docker/docker_files/Dockerfile
  8.     restart: unless-stopped
  9.     command: python manage.py runserver 0.0.0.0:8000
  10.     volumes:
  11.       - ./backend:/code
  12.     ports:
  13.       - 8000:8000
  14.     env_file:
  15.       - .env
  17.   app:
  18.     build:
  19.       context: .
  20.       dockerfile: backend/docker/docker_files/Dockerfile_app
  21.     platform: linux/amd64
  22.     restart: unless-stopped
  23.     ports:
  24.       - 5000:5000

File Dockerfile:

  1. FROM python:3.10
  3. ENV PYTHONUNBUFFERED 1
  4. ENV PYTHONDONTWRITEBYTECODE 1
  6. RUN set -e; \
  7.     apt-get update ;\
  8.     apt-get -y install netcat ;\
  9.     apt-get -y install gettext ;
  11. RUN mkdir /code
  12. COPY . /code/
  13. WORKDIR /code
  15. RUN set -e; \
  16.     /usr/local/bin/python -m pip install --upgrade pip ;\
  17.     python -m pip install -r /code/requirements.txt ;\
  18.     chmod +x /code/docker/entrypoints/entrypoint.sh ;
  20. EXPOSE 8000
  21. ENTRYPOINT ["/code/docker/entrypoints/entrypoint.sh"]

File entrypoint.sh:

  1. #!/bin/sh
  2. python manage.py makemigrations
  3. python manage.py migrate
  4. python manage.py test
  6. exec "$@"

My structure folder DRF_docker:

  1. DRF_docker
  2. |__server.py
  3. |__venv
  4. |__docker-compose.yml
  5. |__backend
  6.    |__requirements.txt
  7.    |__docker
  8.       |__docker_files
  9.          |__Dockerfile
  10.       |__entrypoints
  11.          |__entrypoint.sh

I tried to remove #!/bin/sh and got the error exec /code/docker/entrypoints/entrypoint.sh: exec format error.
I tried a shorter path to /code/entrypoint.sh, but still, there was no such file or directory.

I tried shorty path to /code/entrypoint.sh and still no such file or directory

你可以尝试更改ENTRYPOINT。
从：

  1. ENTRYPOINT ["/code/docker/entrypoints/entrypoint.sh"]

到：

  1. ENTRYPOINT ["bash", "-e", "/code/docker/entrypoints/entrypoint.sh"]

在Linux上运行Dockerfile时似乎存在问题：

You could try changing the ENTRYPOINT.
From:

  1. ENTRYPOINT [ "/code/docker/entrypoints/entrypoint.sh"]

To:

  1. ENTRYPOINT ["bash", "-e", "/code/docker/entrypoints/entrypoint.sh"]

There seems to be an issue when running the Dockerfile on Linux:
