Auto-reloading of code changes with Django development in Docker with Gunicorn

Question

I\'m using a Docker container for Django development, and the container runs Gunicorn with Nginx. I\'d like code changes to auto-load, but the only way I can get them to loa

Answer 1

I faced very similar problem trying to configure auto-reload of the project with a little bit different setup. I set up volumes but it did not work anyway. After an hour of googling and thorough examination of my code I figured out that volume paths in Dockerfile and docker-compose.yml simply do not match. Make sure that they are the same.

My Dockerfile

FROM python:3.6.9-alpine3.10

COPY ./requirements/local.txt /app/requirements/local.txt

RUN set -ex \
    && apk add --no-cache --virtual .build-deps postgresql-dev git gcc libgcc musl-dev jpeg-dev zlib-dev build-base \
    && python -m venv /env \
    && /env/bin/pip install --upgrade pip \
    && /env/bin/pip install --no-cache-dir -r /app/requirements/local.txt \
    && runDeps="$(scanelf --needed --nobanner --recursive /env \
        | awk '{ gsub(/,/, "\nso:", $2); print "so:" $2 }' \
        | sort -u \
        | xargs -r apk info --installed \
        | sort -u)" \
    && apk add --virtual rundeps $runDeps \
    && apk del .build-deps

### Here is the path to the project
COPY . /app

WORKDIR /app/project

ENV VIRTUAL_ENV /env
ENV PATH /env/bin:$PATH
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

EXPOSE 8088

My docker-compose.yml

version: '3'


services:

  web:
    build:
      context: ../..
      dockerfile: compose/local/Dockerfile
    restart: on-failure
    command: python manage.py runserver 0.0.0.0:8088 --settings=project.settings.local
    volumes:
      # - .:/var/www/app  # messed up path
      - .:/app  # correct path
    env_file:
      - ../../.env.local
    depends_on:
      - db
    ports:
      - "8000:8000"
