Nginx doesn't serve static and media with django and Docker

Question

I need to launch my site in production, so I decided to do it with Docker container(at first time, newbie there) with Postgres, nginx and Django, everything is working inside a container, but on launched site I have in console 404 error with static and media. I did a research, but still haven't found the answer for my case. Could somebody advise what I need to fix there?

There is my Dockerfile

###########
# BUILDER #

# pull official base image
FROM python:3.9.6-alpine as builder

# set work directory
WORKDIR /usr/src/my_shop

# set environment variables

# install psycopg2 and Pillow dependencies

RUN chown -R app:app $APP_HOME

# change to the app user
USER app

# run entrypoint.prod.sh
ENTRYPOINT ["/home/app/web/entrypoint.prod.sh"]

There is docker-compose.yml

version: '3.8'

services:
  web:
    build:
      context: ./
      dockerfile: Dockerfile.prod
    command: gunicorn shop.wsgi:application --bind 0.0.0.0:8000
    volumes:
      - static_volume:/home/app/web/staticfiles
      - media_volume:/home/app/web/mediafiles
    ports:
      - 8000:8000
    env_file:
      - ./.env.prod
    depends_on:
      - db
  db:
    image: postgres:13.0-alpine
    volumes:
      - postgres_data:/var/lib/postgresql/data/
    env_file:
      - ./.env.prod.db
  nginx:
    build: ./nginx
    volumes:
      - static_volume:/home/app/web/staticfiles
      - media_volume:/home/app/web/mediafiles
    ports:
      - "80:80"
    depends_on:
      - web

volumes:
  postgres_data:
  static_volume:
  media_volume:

and there is nginx settings:

upstream shop {
    server web:8000;
}

server {

    listen 80;

    location / {
        proxy_pass http://shop;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $host;
        proxy_redirect off;
    }

    location /static/ {
        alias /home/app/web/staticfiles/;
    }

    location /media/ {
        alias /home/app/web/mediafiles/;
    }
}

What I have in settings.py

STATIC_URL = '/static/'
STATIC_ROOT = BASE_DIR / "staticfiles"
STATICFILES_FINDERS = [
    "django.contrib.staticfiles.finders.FileSystemFinder",
    "django.contrib.staticfiles.finders.AppDirectoriesFinder",
]

MEDIA_URL = '/media/'
MEDIA_ROOT = BASE_DIR / "mediafiles"

Dockerfile for nginx

FROM nginx:1.21-alpine

RUN rm /etc/nginx/conf.d/default.conf
COPY nginx.conf /etc/nginx/conf.d

And of course after container launching I did:

docker-compose -f docker-compose.prod.yml exec web python manage.py migrate --noinput

and then

docker-compose -f docker-compose.prod.yml exec web python manage.py collectstatic --no-input --clear

I did it according to this instruction with some fixes https://testdriven.io/blog/dockerizing-django-with-postgres-gunicorn-and-nginx/
