Docker Redis Django连接被拒绝

我正在使用Django REST框架、Django、Postgres作为数据库、Redis作为缓存来编写这个项目。我想把我的项目归档。 但Redis不想访问连接。 Django设置：

CACHES = {
    'default': {
        'BACKEND': 'django_redis.cache.RedisCache',
        'LOCATION': 'redis://127.0.0.1:6379/',
        'OPTIONS': {
            'CLIENT_CLASS': 'django_redis.client.DefaultClient',
        }
    }
}

docker-compose.yml：

services:

  postgres:
    image: postgres:latest
    env_file:
      - ./src/main/.env
    volumes:
      - ./scripts/postgres:/docker-entrypoint-initdb.d

  polls:
    build: .
    volumes:
      - .:/code
    env_file:
      - ./src/main/.env
    ports:
      - "8000:8000"
    depends_on:
      - postgres
      - redis
    command: ./scripts/wait_for_it.sh

  redis:
    restart: always
    image: redis:3.2.0
    expose:
      - "6379"

当我运行命令启动容器时，会出现以下警告：

polls_cache | 1:M 15 Aug 10:47:36.719 # WARNING: The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.

polls_cache | 1:M 15 Aug 10:47:36.720 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
polls_cache | 1:M 15 Aug 10:47:36.720 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.
polls_cache | 1:M 15 Aug 10:47:36.720 * The server is now ready to accept connections on port 6379

当我尝试对使用Redis进行缓存的端点执行GET请求时，会出现异常：

ConnectionError at /question/top/
Error 111 connecting to 127.0.0.1:6379. Connection refused.

可能有人有类似的问题？

将连接字符串更改为以下-

CACHES = {
    'default': {
        'BACKEND': 'django_redis.cache.RedisCache',
        'LOCATION': 'redis://redis:6379/',
        'OPTIONS': {
            'CLIENT_CLASS': 'django_redis.client.DefaultClient',
        }
    }
}

对于轮询服务容器，

127.0.0.1

是轮询容器本身。使用docker compose时，始终可以使用其服务名称（如

redis

polls

postgres
）访问容器，也就是说，更改
位置中的
127.0.0.1
键以指向redis容器的主机名，
redis
。
