Why is my .dockerignore file not working?

问题

I have a .dockerignore file with the following contents:

  1. **/__pycache__
  2. **/.venv
  3. **/.git
  4. **/.gitignore
  5. **/.dockerignore
  6. **/dockerfile*
  7. **/docker-compose*
  9. postgres_data/

and this is my docker-compose.yml

  1. version: '3.8'
  3. services:
  4.   django_app:
  5.     image: django_image
  6.     container_name: Django
  7.     build:
  8.       context: .
  9.       dockerfile: django_app/dockerfile
  10.     command:
  11.       - /bin/sh
  12.       - -c
  13.       - |
  14.         python manage.py makemigrations
  15.         python manage.py migrate --no-input
  16.         python manage.py collectstatic --no-input
  17.         gunicorn configurations.wsgi:application --bind 0.0.0.0:8000        
  18.     volumes:
  19.       - ./django_app:/django_app
  20.     ports:
  21.       - 8000:8000
  22.     env_file:
  23.       - django_app/.envs/.env.django
  24.       - django_app/.envs/.env.postgres
  25.     depends_on:
  26.       - postgres_host
  28.   postgres_host:
  29.     container_name: Postgres
  30.     image: postgres:15-bookworm
  31.     restart: unless-stopped
  32.     ports:
  33.       - 5432:5432
  34.     volumes:
  35.       - ./postgres_data/:/var/lib/postgresql/data/
  36.     env_file:
  37.       - django_app/.envs/.env.postgres

However, when I build my Docker image using docker-compose up, all of the files in the .dockerignore file are still being copied into the container. What could be causing this issue?

The volumes: block causes the /django_app directory in the container to be connected to the host system. You are not seeing the contents of the image at all; .dockerignore doesn't apply; and if your Dockerfile does any work like dynamically building files or rearranging the directory tree, this gets hidden.

You should delete the volumes: block, and then the container filesystem will look like what's in the image. As a bonus, you also won't need a local copy of the application source to run the image, and you'll get consistent behavior running the image anywhere (like a production system) independent of what's on the host.
