I have a basic Django project that I have put into a docker container.

Currently I have it running on https locally just for the development phase because it is a requirement.

When I run my program without docker it opens successfully on https://127.0.0.1:8000. Which is the address the message says its currently running on.

But when I use the same logic on my docker container after running docker-compose up the container compiles but I am unable to load the web page. When I try to run the address from the docker container I just get the generic site cannot be reached error.

Link I used to get https during development:

Docker-compose.yml

version: "3.8"
   
services:
    django:
        build: .
        container_name: frontend
        command: python manage.py runserver_plus --cert-file cert.pem --key-file key.pem

        volumes:
            - .:/usr/src/app
        ports:
            - "8000:8000"
        depends_on:
            - pgdb
    pgdb:
        image: postgres
        container_name: backend
        environment:
        - POSTGRES_DB=postgres
        - POSTGRES_USER=postgres
        - POSTGRES_PASSWORD=postgres

Dockerfile

FROM python:3.12.3

ENV PYTHONUNBUFFERED=1

WORKDIR /usr/src/app

COPY requirements.txt ./

RUN pip install django

RUN pip install -r requirements.txt

settings.py

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'location',
    'rest_framework',
    'django_extensions',
 
]

I tried to change the port number but it still didn’t work.
