Nginx docker container not accepting and serving flask from container

So I have banging my head on this issue for the past hours, and I have got a docker-compose.yml file

version: '2'

services:
  web:
    restart: always
    build: ./web_app
    expose:
      - "8000"
    ports:
      - "8000:8000"
    volumes:
      - ./web_app:/data/web
    command: /usr/local/bin/gunicorn web_interface:app -w 4 -t 90 --log-level=debug -b 0.0.0.0:8000 --reload
    depends_on:
      - postgres

  nginx:
    restart: always
    build: ./nginx
    ports:
     - "8080:80"
    volumes_from:
      - web
    depends_on:
      - web

  postgres:
    restart: always
    image: postgres:latest
    volumes_from:
      - data
    volumes:
      - ./postgres/docker-entrypoint-initdb.d:/docker-entrypoint-initdb.d
      - ./backups/postgresql:/backup
    expose:
      - "5432"

  data:
    restart: always
    image: alpine
    volumes:
      - /var/lib/postgresql
    tty: true

However, when I docker-compose up and then navigate to localhost:8880, I get nothing served. Is like the nginx server is not accepting connections through the localhost.

nginx.conf 

server {

    listen 80;
    server_name localhost;
    charset utf-8;

    location /static/ {
        alias /data/web/crm/web_interface;
    }

    location = /favicon.ico {
        alias /data/web/crm/web_interface/static/favicon.ico;
    }

    location / {
        proxy_pass http://web:8000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }

}

nginx/Dockerfile

FROM nginx:latest

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

COPY ./nginx.conf /etc/nginx/conf.d/nginx.conf

And this is whats in my terminal:terminal shot

I have been following this tutorial fairly closely, but it cant seem to serve the Flask App that I have created. Any ideas?

Try changing the port mapping for nginx service as below: 

 ports:
  - "8880:80"

or make nginx listen on port 8080.
