撤销部署
docker stack rm redis_cluster
如果需要重新部署集群，redis集群为了保证数据统一，需要清除数据卷。
# 每个节点都需要执行
docker volume prune
测试
进入其中一个节点容器，依次查看集群信息
docker exec -it xxx bash
redis-cli -c -h redis-node1 info
![[(img-O2FqAYVp-1664157328891)(C:\Users\Administrator\AppData\Roaming\Typora\typora-user-images\image-20220824155036853.png)]](https://img-blog.csdnimg.cn/bd3cfa937b9f4b8091f5dec0e9ee5834.png)
测试读写数据
测试其中一个主节点宕机，这里删除了主节点1，节点1对应的从节点是节点4，节点1宕机后节点4成为主节点
docker service rm redis-swarm_redis-node1
# 查看
root@redis-node2:/data# redis-cli -c -h redis-node1
Could not connect to Redis at redis-node1:6379: Name or service not known
not connected>
root@redis-node2:/data# redis-cli -c -h redis-node4
redis-node4:6379> info
问题
redis-cli --cluster create redis-node1:6379 ...省略
在容器中使用redis-cli创建集群时，无法使用容器名创建，只能使用容器的ip，因为redis-cli对别
