我正在像这样使用 Docker 运行 Redis 本地集群

docker run --env "IP=0.0.0.0" -p 7000-7007:7000-7007 -p 5000-5002:5000-5002 -p 6379:6379 grokzen/redis-cluster:5.0.3

通过类似telnet的方式连接时,我无法发送命令

telnet localhost 7000

但是当尝试使用以下代码连接生菜客户端时

    RedisURI redisURI = RedisURI.Builder.redis("localhost", 7000).build();
RedisClusterClient client = RedisClusterClient.create(redisURI);
StatefulRedisClusterConnection<String, String> connection = client.connect();
RedisStringCommands sync = connection.sync();
String value = (String) sync.get("key");

抛出以下异常

Exception in thread "main" io.lettuce.core.RedisException: Cannot retrieve initial cluster partitions from initial URIs [RedisURI [host='localhost', port=7000]]
