I am installed django-environ and try to get my values from .env. I haven't problems when I run server in local, but when i run my app with docker-compose up --build I have error:

Traceback (most recent call last):

I have my .env file:

SECRET_KEY="django-insecure-t+)^5*1syzvs=p%tiy324)zxz26$ra!+__8)y8=!hnyjn_cg3m"

My docker-compose:

version: "3.10"

    env_file:
      - ./support/.env
    volumes:

    env_file:
      - ./support/.env
    volumes:
      - .:/support
    depends_on:

      - redis
  redis:

  celery:
    restart: always
    build:
      context: .
    command: bash -c "cd support && celery -A support worker -l info"
    env_file:
      - ./support/.env
    depends_on:
      - postgres
      - redis
      - web

My Dockerfile:

FROM python:3.10 as prod

ENV PYTHONUNBUFFERED=1 \
    POETRY_HOME=/opt/poetry \
    POETRY_VIRTUALENVS_CREATE="false"

ENV PATH="${POETRY_HOME}/bin:$PATH"

WORKDIR /app

RUN apt update && \
    apt install make

COPY Makefile poetry.lock pyproject.toml /app/

RUN curl -sSL https://install.python-poetry.org | python3 -

RUN make install-prod

COPY support /app/support

CMD make make-migrations && make migrate && make run-app

In settings.py:

 import environ
    
 env = environ.Env(DEBUG=(bool, False))
    
 BASE_DIR = Path(__file__).resolve().parent.parent
 environ.Env.read_env(os.path.join(BASE_DIR, ".env"))
 SECRET_KEY = env("SECRET_KEY")

I am tried use packege python-dotenv, poetry-dotenv, dotenv, load_env and all give me this error.

I have the same issue with you when I have the following conditions

  • I'm using Arch Linux
  • I have pyenv usng mutiple version of Python
  • I have docker-compose installed using pip from different version of python

Solution

  • Uninstall all docker-compose install via pip in all Python version, then install docker-compose that is provided by AUR in my case yay -S docker-compose. Tada! now it works.
