How to create a predis client that does both clustering and replication?

问题

note: this is a follow up to this question

I need to be able to do both redis clustering and replication. This is the config file I have in laravel:

    'redis' => [

        'clustered' => [
            'client' => 'predis',
            'cluster' => true,
            'options' => [ 'cluster' => 'redis',
                           'replication' => true 
                         ],
            'clusters' => [
                        // masters
                        [
                            'host' => env('REDIS_SHARD_1_HOST', '127.0.01'),
                            'password' => env('REDIS_PASSWORD', null),
                            'port' => env('REDIS_SHARD_1_PORT', 6379),
                            'database' => 0,
                            'alias' => 'master',
                        ],
                        [
                            'host' => env('REDIS_SHARD_2_HOST', '127.0.01'),
                            'password' => env('REDIS_PASSWORD', null),
                            'port' => env('REDIS_SHARD_2_PORT', 6379),
                            'database' => 0,
                            'alias' => 'master',
                        ],
                        [
                            'host' => env('REDIS_SHARD_3_HOST', '127.0.01'),
                            'password' => env('REDIS_PASSWORD', null),
                            'port' => env('REDIS_SHARD_3_PORT', 6379),
                            'database' => 0,
                            'alias' => 'master',
                        ],
                        // slaves (replicas)
                        [
                            'host' => env('REDIS_SHARD_1_HOST_REPLICA', '127.0.01'),
                            'password' => env('REDIS_PASSWORD', null),
                            'port' => env('REDIS_SHARD_1_PORT_REPLICA', 6379),
                            'database' => 0,
                        ],
                        [
                            'host' => env('REDIS_SHARD_2_HOST_REPLICA', '127.0.01'),
                            'password' => env('REDIS_PASSWORD', null),
                            'port' => env('REDIS_SHARD_2_PORT_REPLICA', 6379),
                            'database' => 0,
                        ],
                        [
                            'host' => env('REDIS_SHARD_3_HOST_REPLICA', '127.0.01'),
                            'password' => env('REDIS_PASSWORD', null),
                            'port' => env('REDIS_SHARD_3_PORT_REPLICA', 6379),
                            'database' => 0,
                        ]
            ],
        ], 

        'default' => [
            'host' => env('REDIS_HOST', '127.0.0.1'),
            'password' => env('REDIS_PASSWORD', null),
            'port'     => 6379,
            'database' => 0,
            'cluster' => false,
        ],
    ]

];

but in my debugger, the connection that gets created in predis has 3 slaves and the last master:

[ *Locals ] [ Superglobals ] [ User defined constants ]

how can i write the config to have three nodes in a cluster, with each node having one replica?
