描述
Describe the bug
I upgraded from 3.5.0 to 4.1.0 and the container itself fails to spawn because the Ryuk container setup fails. I've tried debugging the issue and it looks like it is trying to bind the port exposed on IPv6 to the port on IPv4 (the container_port variable is correct for IPv4), which are for some reason different ports.
$ docker ps

调研方向
从 Reaper._socket.connect 调用开始,跟踪在 Ryuk 设置期间如何获取 container_host 和 container_port。使用报告中的 Colima 和 Docker 版本进行复现,然后为不同的 IPv4 和 IPv6 端口映射添加回归测试覆盖,并确认 Ryuk 能够启动且可靠地接受连接。
