Docker 错误：到0.0.0.0:6379的Redis连接失败-连接到0.0.0.0:6379

我一直在尝试构建经典的投票应用程序。但我的redis和mongodb给出了同样的错误。我必须将我的redis连接到我的节点应用程序，我已尝试以下操作：

//redis
const redisoption = {
    host: "redis",
    port: 6379
};

docker-compose.yml

version: "3"

服务：

vote:
    image: adityagaddhyan/voting-app
    ports: 
        - "3000:3000"
    depends_on:
        - redis
    networks:
        - front-end
        - back-end
    volumes: 
        - ./vote:/app
result:
    image: adityagaddhyan/voting-result
    ports: 
        - "3011:3011"
    depends_on:
        - mongodb
    networks: 
        - back-end
        - front-end
    volumes: 
        - ./result:/app

worker:
    image: adityagaddhyan/service-worker
    depends_on: 
        - redis
        - mongodb
    networks: 
        - back-end
    volumes: 
        - ./worker:/app
redis:
    image : redis
    command: ["redis-server", "--bind", "0.0.0.0", "--port", "6379"
    ports: 
        - "6379:6379"
    networks: 
        - back-end
    volumes: 
        - ./redis:/app
mongodb:
    image: mongo
    ports:
        - "27017:27017"
    volumes: 
        - ./db:/app

我试过各种组合。 我主要有两种错误。 如果我使用主机：“0.0.0.0”，我得到

    Error: Redis connection to 0.0.0.0:6379 failed - connect ECONNREFUSED 0.0.0.0:6379

我是docker的新手，无法解决这个问题。请提供帮助。

主机名

redis

应解析为容器的Docker内部地址，该地址不应为127.0.0.1。您得到的错误来自一个单独的

工作者

容器；你能显示它的配置吗？（

redis

应该可以工作，0.0.0.0在这里没有意义。）“redis”解析为127.0.0.1的部分让我觉得你的docker网络有些奇怪。“后端”和“前端”的设置如何？事实上，我在投票1中也遇到了错误。。同样的错误。在这里检查src代码
