Django app isn't working with docker and nginx - django

Question

I am trying to launch django + docker + nginx web application
I don't see any errors in docker-compose logs. Full log: https://pastebin.com/tUpf5Wv0
But local urls 0.0.0.0:80 or 127.0.0.1:80 are not working.
It seems that problem deals with nginx but I don't see any errors in logs. How can I find the reason of the problem?

Dockerfile
FROM python:3.9-alpine
WORKDIR /project
COPY . .
RUN apk add --update --no-cache --virtual .tmp-build-deps \
gcc libc-dev linux-headers postgresql-dev && \
pip install --no-cache-dir -r requirements.txt
nginx-conf.conf
upstream app {
server django:8000;
}
server {
listen 80;
server_name 127.0.0.1;
location / {
proxy_pass http://django:8000;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_redirect off;
}
location /static/ {
alias /var/www/html/static/;
}
}
Docker compose file (looks fine)

django:
build: ./project # path to Dockerfile

Found out that problem deals with invalid volumes in docker-compose file
The fix: ./project/nginx-conf.d/:/etc/nginx/conf.d
This version is working for me:
version: '3.9'
services:
django:
build: ./project # path to Dockerfile
command: sh -c "
python manage.py makemigrations
&& python manage.py migrate
&& gunicorn --bind 0.0.0.0:8000 core_app.wsgi"
volumes:
- ./project:/project
- ./project/static:/project/static
expose:
- 8000
environment:
- DATABASE_URL=postgres://postgres:post222#db:5432/lk_potok_4"
- DEBUG=1
db:
image: postgres:13-alpine
volumes:
- pg_data:/var/lib/postgresql/data/
expose:
- 5432
environment:
- POSTGRES_USER=postgres
- POSTGRES_PASSWORD=post222
- POSTGRES_DB=lk_potok_4
nginx:
image: nginx:1.19.8-alpine
depends_on:
- django
ports:
- "80:80"
volumes:
- ./project/static:/var/www/html/static
- ./project/nginx-conf.d/:/etc/nginx/conf.d
celery:
build: ./project
