lettuce 4.2 RELEASE NOTES

lettuce 4.2 requires Java 8 and cannot be used with Java 6 or 7.

Redis Cluster and SSL

Redis 3.2 introduces an option to announce a specific IP address/port using cluster-announce-ip and cluster-announce-port. This is useful for Docker and NAT'ed use cases. Furthermore, you can "hide" your Redis Cluster nodes behind anything, for example, stunnel. A Redis Cluster node will announce the specified port/IP which maps then to stunnel, and you get an SSL-protected Redis Cluster.

Redis Cluster SSL works pretty much the same as Redis Standalone with SSL. You can configure SSL and other SSL/TLS options using RedisURI.

RedisURI redisURI = RedisURI.Builder.redis(host(), 7443)
                                .withSsl(true)
                                .withVerifyPeer(false)
                                .build();

RedisClusterClient redisClusterClient = RedisClusterClient.create(redisURI);
StatefulRedisClusterConnection<String, String> connection = redisClusterClient.connect();

You should disable the verifyPeer option. The reason is the address resolution mechanism is decoupled from the SSL verification part. With enabled verification all connections would be verified against the first RedisURI node.

When creating a RedisClusterClient using RedisClusterClientFactoryBean the verifyPeer option is disabled by default.
