我似乎在尝试通过python/django设置redis示例时遇到了问题。我有很多容器在docker-compose中运行，而其他容器能够正确连接，当尝试使用Django时，我得到：

所以我试着改变redis容器的名称，看看它是否有帮助，我已经检查了网络存在，其他容器也可以连接没有任何问题。

redis:
    image: redis:6

      - redis
    ports:

    healthcheck:

经过研究，我意识到在构建镜像时，由于Docker创建了一个临时容器来执行构建管道，因此无法建立到另一个网络的连接。解决此问题的一种方法是使用主机的IP地址连接到Redis。
尽管如此，正如大卫迷宫所指出的，探索collectstatics试图与Redis建立连接的潜在原因是很有趣的。
