- 查看redis集群容器的ip地址
docker inspect --format='{{.Name}} - {{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $(docker ps -aq) | grep redis_cluster
//输出结果

- 设置redis集群
docker exec -it de46397b5623 /bin/bash
/usr/local/bin/redis-cli --cluster create 172.23.0.5:6379 172.23.0.2:6379 172.23.0.6:6379 172.23.0.7:6379 172.23.0.3:6379 172.23.0.4:6379 -cluster-replicas 1

-> Redirected to slot [9189] located at 172.23.0.7:6379
OK
- 其他：如果要使用 php 的 RedisCluster, node节点配置 需要和redis-cli --cluster create ip:port 设置的保持一致
