在swarm集群的Manager节点中创建
mkdir /root/redis-swarm
cd /root/redis-swarm
vi docker-compose.yml
docker compose.yml
说明：
-
前6个服务为redis节点，最后一个redis-start是用于创建集群，利用redis-cli客户端搭建集群，该服务搭建完redis集群后会自动停止运行。
-
redis-start需要等待前6个redis节点的执行完毕才能创建集群，因此需要用到脚本wait-for-it.sh
-
由于redis-cli --cluster create不支持网络别名，所以另写脚本redis-start.sh
使用这套脚本同样可以单机部署集群，只需要在启动时不使用swarm启动就可以了，然后把docker-compose.yml中的网络模式driver: overlay给注释掉即可
