容器内端口不能都是是6379，集群总线接口是端口号+10000
端口号与network_mode: "host"不能一起配置，出现下述问题“主机”网络模式与端口绑定不兼容问题，具体看github,有对应解释。
ERROR: for cluster_redis_6379 "host" network_mode is
incompatible with port_bindings

启动redis容器
docker-compose up -d
进入容器
docker exec -it cluster_redis_6379 bash
搭建集群
redis-cli -a admin --cluster create \

--cluster-replicas 1 #一个主节点分配一个从节点

遇到的问题
如果一直卡在Waiting for the cluster to join，那一般是端口问题，看看集群总线端口是否开启，我在这遇到问题，修改了redis.conf中的端口，将容器中端口都是6379改成不同的,并且在docker-compose.yml的port中，加上各个节点的总线端口好了。

集群数据库数量问题
Response received : -ERR SELECT is not allowed in cluster mode
在集群模式下这个配置是不起作用的，集群客户端是不支持多数据库db的，只有一个数据库默认是SELECT 0;
在某个控制台里，比如6379,如果存放的key值对应的槽位不在6379的槽位之中，是不能存放的文章来源地址https://www.toymoban.com/news/detail-667969.html
