App Description

I have an app with django-gunicorn for back-end and reactjs-nginx with front-end all containerized as well as hosted on aws ec2 instance.

Problem

On development environment, media files are being saved in the 'media' directory permanently. Tho, those files are only saved on the current running docker container on production time. As a result, the files will be removed when I rebuild/stopped the container for a new code push.

Expectation

I wanted to store the file on the 'media' folder for permanent use.

Important code

settings.py

ENV_PATH = Path(__file__).resolve().parent.parent
STATIC_ROOT = BASE_DIR / 'django_static'
STATIC_URL = '/django_static/'

MEDIA_ROOT = BASE_DIR / 'media/'

MEDIA_URL = '/media/'

docker-compose-production.yml

version: "3.3"

    db:
       image: postgres
       restart: always #Prevent postgres from stopping the container
