Django каналов, Docker Compose, Errno 111] Ошибка вызова Connect ('127.0.0.2', 6379)

Я следую руководству Django Каналы, доступному по адресу https://channels.readthedocs.io/en/latest/tutorial/part_2.html

Я использую docker -compose для создания сервера redis:

docker-compose.yml

  redis:
    image: "redis:alpine"

    command: redis-server --requirepass letmein

    ports:
     - "6379:6379"

    volumes:
      - ./redis.conf:/usr/local/etc/redis/redis.conf


    environment:
     - REDIS_REPLICATION_MODE=master

    networks:
      node_net:
        ipv4_address: 127.0.0.2

networks:
  node_net:
    ipam:
    driver: default
  config:
    - subnet: 127.0.0.0/16

При попытке проверить соединение с 

async_to_sync(channel_layer.send)('test_channel', {'type': 'hello'})

я получаю сообщение об ошибке 

`File "<console>", line 1, in <module>

Совет доступен по адресу: Docker [Errno 111] Ошибка вызова соединения ('127.0.0.1', 6379) описывает изменение 127.0.0.1:6379 на redis:6379. Однако неясно, где это изменение должно произойти:

в моем settings.py? 

`CHANNEL_LAYERS = {
    'default': {
        'BACKEND': 'channels_redis.core.RedisChannelLayer',
        'CONFIG': {
            "hosts": [('127.0.0.2', 6379)],
        },
    },
}`

или в моем docker-compose.yml? или другое место? Заранее благодарю :)

У вас '127.0.0.2' вместо '127.0.0.1' для localhost
