（1） 进行网络设置
docker network create --subnet=172.19.0.0/24 redis-net
build_one 6382 redis6382 172.19.0.2
build_one 6383 redis6383 172.19.0.3
build_one 6384 redis6384 172.19.0.4
build_one 6385 redis6385 172.19.0.5
build_one 6386 redis6386 172.19.0.6
build_one 6387 redis6387 172.19.0.7
Redis Cluster与Docker机制兼容。 如果在映射后的IP进行集群配置，会失败
方法1，如本文，进行内部网桥设置，进行不同IP，相同端口配置；
方法2，https://blog.csdn.net/x3499633/article/details/88637819 。进行--net host，进行相同 的IP，不同的端口。
总之，就是NAT后的端口就不行了。
（2） 进行集群配置
