Docker NGINX setup to run Django project is giving invalid port specification error

I am trying to setup Docker for my django project. I believe everything is setup to run docker in my machine. Currently, the docker version gives following output:

Client version: 1.6.2
Client API version: 1.18
Go version (client): go1.2.1
Git commit (client): 7c8fca2
OS/Arch (client): linux/amd64
Server version: 17.05.0-ce
Server API version: 1.29
Go version (server): go1.7.5
Git commit (server): 89658be
OS/Arch (server): linux/amd64

I have setup my docker-compose.yml file as follows:

version: '3'
services:
  nginx:
    restart: always
    image: nginx:latest
    container_name: NGINX
    ports:
      - "8000:8000"
    volumes:
      - ./src:/src
      - ./config/nginx:/etc/nginx/conf.d
      - /static:/static
    depends_on:
      - web
  web:
    restart: always
    build: .
    container_name: DJANGO
    command: bash -c "python manage.py makemigrations && python manage.py migrate && gunicorn loop.wsgi -b 0.0.0.0:8000 --reload"
    depends_on:
      - db
    volumes:
      - ./src:/src
      - /static:/static
    expose:
      - "8000"

  db:
    restart: always
    image: postgres:latest
    container_name: PSQL

docker-compose build successfully builds docker images and shows following message:

Successfully built 6b13b02488dc
Successfully tagged loopserver_web:latest
nginx uses an image, skipping

But, when I try to run docker-compose up following error occurs:

Creating NGINX ... 
Creating NGINX ... error

ERROR: for NGINX  Cannot create container for service nginx: invalid port specification: "None"

ERROR: for nginx  Cannot create container for service nginx: invalid port specification: "None"
ERROR: Encountered errors while bringing up the project.

And theserver.conf file inside config/nginx folder.

upstream web {  
  ip_hash;
  server web:8000;
}

# portal
server {  
  location /static/ {    
        autoindex on;    
        alias /static/; 
    }
  location / {
        proxy_pass http://web/;
    }
  listen 8000;
  server_name localhost;
}

I am using docker for the first time and stuck with this error. Any guidance will be very helpful.

I leave the answer here to consult in the future.

As we investigated, it seems that there is some issue in your docker-compose version (< 1.12.0) with python3.

Bug: https://github.com/docker/compose/issues/4729

They recommend to upgrade to Python 3.4.4+ or 3.5.1+, and it should be fixed.

in web service, just add:

environment:
   - NGINX_HOST=foobar.com
   - NGINX_PORT=80

for more information: docker nginx
