docker 集群部署问题 stream_socket_client(): unable to connect to tcp://172.25.70.8:2900

在 docker 集群部署中如果 分成3个应用 gateway register bussiness 。gateway 启动两个容器不会出险问题。但当 gateway 启动3个的时候就会报如下错误 ErrorException: stream_socket_client(): unable to connect to tcp://172.25.70.8:2900 (Connection timed out) in /data/nas/codes/wanjia-video/vendor/workerman/gateway-worker/src/Lib/Gateway.php:759
172.25.70 为第三个容器的本地 IP 。环境和配置如下。麻烦大神看一下。用的是阿里云的容器服务器
