Question

我有一个在 docker 容器（linux python3.6 基础映像）中运行的 python 3.6 应用程序，该应用程序需要访问另一个带有 redis 实例的容器。我在默认桥接网络上运行了两个容器，并且我已将第一个容器配置为使用第二个容器的 IPv4Address 指向第二个容器：

CELERY_RESULT_BACKEND = redis://172.17.0.3:6379/0

根据 docker 上的教程，当它们在同一台主机上运行时（没有防火墙等），这就是将一个容器连接到另一个容器所需的全部内容。但是，当我尝试连接到 redis 容器时，我不断收到 [Errno 111] 连接被拒绝。我已检查是否启用了 ICC，我的默认网桥网络如下所示：
