I'm learning how dockerize a Django project. So, I've created a simple hello world with Django. After this I've created my Dockerfile:
# syntax=docker/dockerfile:1
# Official Ubuntu Image as Layer
FROM ubuntu:20.04 as os
# Disable Prompt During Packages Installation
ARG DEBIAN_FRONTEND=noninteractive
# Update&Upgrade Ubuntu
RUN apt update && apt upgrade -y
# OS as Layer
FROM os as gis-os
# Disable Prompt During Packages Installation
ARG DEBIAN_FRONTEND=noninteractive
# Set Python environment variables
# Prevents Python from writing pyc files to disc
ENV PYTHONDONTWRITEBYTECODE 1
# Prevents Python from buffering stdout and stderr
ENV PYTHONUNBUFFERED 1
# Install python and upgrade pip
RUN apt install -y python3-pip build-essential
RUN pip3 install --upgrade pip
# Installing Geospatial libraries
RUN apt install -y libpq-dev
# Install PROJ
RUN apt install -y libproj-dev proj-data proj-bin unzip
# Install GEOS
RUN apt install -y libgeos-dev
# Install GDAL
RUN apt install -y tzdata
RUN apt install -y libgdal-dev python3-gdal gdal-bin
# GIS-OS as Layer
FROM gis-os as djangoproject
# Update&Upgrade Layer
RUN apt update && apt upgrade -y
# Set work directory
WORKDIR /app
# Copy project data
COPY . ./djangodocker
# Create staticfiles directory
RUN mkdir -p static-folder
# Create media directory
RUN mkdir -p media-folder
# Install project dependencies
RUN pip3 install --no-cache-dir -r ./djangodocker/requirements.txt
## Active entrypoint.sh
RUN chmod +x /app/djangodocker/entrypoint.sh
# Run entrypoint.sh
ENTRYPOINT ["/app/djangodocker/entrypoint.sh"]
# DJANGOPROJECT as Layer
FROM djangoproject as gunicorn-setting-up
# Update&Upgrade Layer
RUN apt update && apt upgrade -y
# Install Gunicorn
RUN pip3 install gunicorn
NB: My goal is to obtain a Geodjango project, so I need many stuff related to GIS field.
Alongside Dockerfile I've the entrypoint.sh.
Below the docker-compose file:
version: '3.7'
services:
website:
container_name: web_project
image: dev-project/django
build: djangodocker
restart: always
env_file: dev.env
command: python3 djangodocker/manage.py runserver 0.0.0.0:8000
ports:
- 8000:8000
When I run sudo docker-compose -f docker-compose-dev.yml up -d --build I can navigate inside my project. But when I use:
command: gunicorn djangodocker.wsgi:application --bind 0.0.0.0:8000
Instead of:
command: python3 djangodocker/manage.py runserver 0.0.0.0:8000
I see the error below:

The image below shows the project tree.
It is my first project with Docker, I don't understand why Gunicorn can't see djangodocker.wsgi, I've tried with djangodocker.djangodocker.wsgi without fortune.
