java - 如何在集群模式下运行docker redis？

Question

我启动了我的 redis docker 容器:

docker run --privileged=true -p 6379:6379 --name TestRedis -d redis

当我尝试在集群模式下从 Spring Redis 使用它时，出现错误:

我需要做什么才能使其以集群方式运行？

当你只是像你一样运行redis Docker镜像时，它会根据它的Dockerfile和内置配置启动，它没有开启集群。 Chris Tanner 向您指出的存储库使用相同的基础镜像，但添加了激活集群的配置。但是，您需要克隆该存储库并构建镜像，然后才能运行它。存储库在自述文件中有关于如何构建和运行它的很好的说明，尽管 docker run 出于某种原因遗漏了图像名称。克隆 repo，cd 到其中，然后执行以下操作:

docker build -t testredis/redis-cluster .
docker run -i -t -p 7000:7000 -p 7001:7001 -p 7002:7002 -p 7003:7003 -p 7004:7004 -p 7005:7005 -p 7006:7006 -p 7007:7007 testredis/redis-cluster

这将使集群运行，您可以将客户端指向端口 7000。
