Docker installing wrong django packages - django

Question

Host Machine: WIndows 10
I created a django project that uses an sqlite database. I tried to put my django app in a container using the following dockerfile:
FROM python:3.5
#Enviromental variables
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1
#Work Dir
ADD . /code
WORKDIR /code
# Install dependencies
RUN pip install -r requirements.txt
Dockercompose file:
version: '3.7'
services:
db:
image: postgres:11.1-alpine
volumes:
- pgdata:/var/lib/postgresql/data/
ports:
- 5432:5432
web:
build: .
command: python /code/manage.py runserver 0.0.0.0:8000
volumes:
- .:/code
ports:
- 8000:8000
depends_on:
- db
volumes:
pgdata:
Now, when I try to run the code it gives me this error:
Starting iomweb_db_1 ... done
Starting iomweb_web_1 ... done
Attaching to iomweb_db_1, iomweb_web_1

Now, I can manually fix this problem inside of the container under the models; but I am not sure where the docker container is getting these models from. I tried to change the models from the python in the system but still doing this. I would like to fix this so I do not have to fix this manually every time I build this container. I could do a docker commit; but still any help to find out why docker is taking this models.py from.

Answer 1

I was able to resolve this issue. The problem was that django-registration-redux library that I was installing was not compatible with Django 2.0. Once I updated this package to the latest version it was all good.

Answer 2

I used to get the same error but adding this to my docker file fixed the problem:
RUN apt-get update && apt-get install -y --no-install-recommends \
tzdata \
libopencv-dev \
build-essential \
libssl-dev \
libpq-dev \
libcurl4-gnutls-dev \
libexpat1-dev \
gettext \
unzip \
python3-setuptools \
python3-pip \
python3-dev \
python3-venv \
git \
&& \
apt-get clean && \
rm -rf /var/lib/apt/lists/* \
\
It installs a lot of packages but the error was solved

Answer 3

Create a run.sh file and write below;
python manage.py makemigrations && \
python manage.py migrate && \
python manage.py runserver 0.0.0.0:8000
And in you docker-compose.yml file write below;
...
web:
build: .
command: sh run.sh
...
