暂且使用此集群：redis6.09 集群安装(docker-compose)
1. 迁移工具
github.com/tanruixing8…
另外自己做了一个包含此工具的镜像,可以下载使用
docker pull lyman1567/redis-migrate-tool
2 迁移数据配置
#rmt.conf
[source]
type: rdb file
servers:
- /usr/local/etc/redis/dump.rdb
[target]
type: redis cluster
servers:
- 10.0.0.10:6379
[common]
listen: 0.0.0.0:8888
3 准备好后，开始部署
$ docker ps

$ docker images
lyman1567/redis-migrate-tool latest 72c4a8146559 11 hours ago 473MB
$ docker run -it --network=container:bea2824575f6 --pid=container:bea2824575f6 -v C:/redis-migrate-tool/data:/usr/local/etc lyman1567/redis-migrate-tool bash
4 进入集群容器执行
[root@bea2824575f6 /]# cd /usr/local/etc
[root@bea2824575f6 etc]# ls
conf redis
[root@bea2824575f6 etc]# cd conf
[root@bea2824575f6 etc]# vi rmt.conf
[source]
type: rdb file
servers:
- /usr/local/etc/redis/dump.rdb
[target]
type: redis cluster
servers:
- 10.0.0.10:6379
[common]
listen: 0.0.0.0:8888
5 确认好后，执行
[root@bea2824575f6 conf]# redis-migrate-tool -c rmt.conf -o output.log -d
6 查看log

可以看出来：rdb总用时97秒

如果想用两个不同的容器加入同一网络，进行数据迁移可以参考下面博文：
