service refers to undefined volume - django

Question

I want to share temp files between Django project and celery worker (it works with TemporaryUploadedFiles, so I want to have access to these files from celery worker to manage them). I've read about shared volumes, so I tried to imlement it in my docker-compose file and run it, but the command gave me this error:
$ docker compose up --build
service "web" refers to undefined volume shared_web_volume/: invalid compose project
And sometimes "web" replace with "celery", so both celery and django have no access to this volume.
Here is my docker-compose.yml file:
volumes:
shared_web_volume:
postgres_data:
services:
db:
image: postgres:12.0-alpine
ports:
- "5432:5432"
volumes:
- postgres_data:/var/lib/postgresql/data/
env_file:
- ./.env
web:
build:
context: ./MoreEnergy
dockerfile: Dockerfile
entrypoint: sh ./entrypoint.sh
command: python manage.py runserver 0.0.0.0:8000
volumes:
- "shared_web_volume/:/MoreEnergy/"
ports:
- 1337:8000
env_file:
- ./.env
depends_on:
- db
celery:
build:
context: ./MoreEnergy
dockerfile: Dockerfile
entrypoint: sh ./entrypoint.sh
command: celery -A MoreEnergy worker --loglevel=info
volumes:
- "shared_web_volume/:/MoreEnergy/"
env_file:
- ./.env
depends_on:
- web
- redis
redis:
image: redis:5-alpine
What am I doing wrong?
Upd: temp dir is my project folder (I've set it with FILE_UPLOAD_TEMP_DIR variable in settings file), so I don't need to make one more volume only for shared temp files (If I have to, tell me).

Answer 1

your shared volume name is shared_web_volume and it's different from the one that you use in the volumes section which is shared_web_volume/
so my suggestion is to erase the forward slash to be like this
volumes:
- "shared_web_volume:/MoreEnergy/"
Don't forget to do the same thing in celery container
