Django Nginx Docker Gunicorn cant reach - django

Question

Sorry if it the answer seems obvious, but I've been bashing my head for the past couple of hours.
I've been following multiple tutorials trying to dockerize my application. No matter what combination of url:port or just url I tried I can't access the pages.
I have zero clue what am I doing wrong. I am assuming the following:
NGINX config plain wrong. How can upstream web know what's web? I assume docker exposes it, but unsure whether this is correct.
web container not exposing address and port properly?
I tried multipled settings, but non work.
I have the following:
Dockerfile
FROM python:3
ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
ADD requirements.txt /code/
RUN pip install -r requirements.txt
ADD . /code/
ADD ./django.conf /etc/nginx/conf.d/default.conf
#COPY ./django.conf /etc/nginx/sites-available/
#RUN ln -s /etc/nginx/sites-available/django.conf /etc/nginx/sites-enabled
docker-compose.yml
version: '3'
services:
db:
image: postgres:9.6
ports:
- "5432:5432"
environment:
- POSTGRES_USER=random_user
- POSTGRES_PASSWORD=random_password
redis:
restart: always
image: redis:4.0
expose:
- "6379"
nginx:
image: nginx:1.14.0
container_name: nginx01
ports:
- "8000:8000"
volumes:
- ./code
depends_on:
- web
web:
build: .
container_name: backend-api
command: bash -c "python manage.py migrate && python manage.py collectstatic --noinput && gunicorn ops4_backend.wsgi -b 0.0.0.0:8000"
depends_on:
- db
volumes:
- ./code
expose:
- "8000"
restart: always
django.conf
upstream web {
ip_hash;
server web:8000;
}
# portal
server {
location / {
proxy_pass http://web:8000;
}
listen 8000;
server_name localhost;
location /static {
autoindex on;
alias /src/static/;
}
}
docker ps -a

I was doing almost the same task yesterday, and the only valuable difference I see is that you include django.conf in Django container, not in nginx one. I have following volume in nginx section of docker-compose.yml:
- ./nginx:/etc/nginx/conf.d (where ./nginx is the folder with django.conf)
EDIT: here is my docker-compose.yml:
version: '3'
services:
nginx:
image: nginx
restart: always
ports:
- "80:8000"
volumes:
- ./nginx:/etc/nginx/conf.d
- ./static_cdn:/static
depends_on:
- web
db:
image: postgres
restart: always
web:
build: .
restart: always
command: bash -c "python3 manage.py makemigrations && python3 manage.py migrate && python3 manage.py collectstatic --no-input && gunicorn core.wsgi -b 0.0.0.0:8000"
volumes:
- .:/code
expose:
- "8000"
depends_on:
- db
django.conf:
upstream web {
ip_hash;
server web:8000;
}
server {
location /static/ {
alias /static/;
}
location / {
proxy_pass http://web/;
}
listen 8000;
server_name localhost;
}
With this setup nginx is available at 127.0.0.1:80 or just 127.0.0.1 as 80 is default http port.

There are so many wrong things, please use this configuration. and then change it step by step toward your specific needs.
also checkout this page that talks about Nginx Docker Configurations because one of your main problems is that you are not exposing django nginx conf that you make:
ADD ./django.conf /etc/nginx/conf.d/default.conf
to nginx container.
so nginx does not know how to map your configs.
