I found a Django project and failed to get it running in Docker container in the following way:
git clone https://github.com/hotdogee/django-blast.git
$ cat requirements.txt
in this files the below dependencies had to be updated:- kombu==3.0.30
- psycopg2==2.8.6
I have the following Dockerfile:
FROM python:2
ENV PYTHONUNBUFFERED=1
WORKDIR /code
COPY requirements.txt /code/
RUN pip install -r requirements.txt
COPY . /code/
For docker-compose.yml
I use:
version: "3"
services:
db:
image: postgres
volumes:
- ./data/db:/var/lib/postgresql/data
environment:
- POSTGRES_DB=postgres
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD=postgres
web:
build: .
command: python manage.py runserver 0.0.0.0:8000
volumes:
- .:/code
ports:
- "8000:8000"
depends_on:
- db
Next, I ran into this error:
$ docker-compose build
