我为我的django应用程序提供了本地＆生产docker-compose服务，在本地服务中一切正常，但是在生产服务daphne中不起作用，同样，redis连接等于并且我没有使用我的docker compos服务的特殊网络配置。

本地撰写：

version: "3"
services:

    app:
        image: app
        build:
            context: .
            dockerfile: ./compose/local/Dockerfile
        environment:
            - DJANGO_SETTINGS_MODULE=psvt.settings.local
        volumes: 
            - ".:/django/"
        ports:
            - "8000:8000"
        depends_on:
            - redis
            - db
        links: 
            - redis:redis
            - db:postgres

    redis:
        image: redis
        restart: always
        expose:
            - '6379'

    daphne:
        restart: always
        image: "app:latest"
        working_dir: /django/
        command: bash -c "daphne -b 0.0.0.0 -p 8001 psvt.asgi:channel_layer"
        ports:
            - "8001:8001"
        environment:
            - REDIS_HOST=redis
            - DJANGO_SETTINGS_MODULE=psvt.settings.local
        depends_on:
            - redis
        links:
            - redis

    db:
        image: postgres:10.1-alpine
        volumes:
            - postgres_data:/var/lib/postgresql/data/
        expose: 
            - "5432"

错误是：

Error trying to receive messages: Error -2 connecting to redis:6379. Name or service not known.
