Laravel 10 - phpredis with sentinels possible?

I'm looking into a way to setup Redis HA using Sentinels, and am looking into drivers that will work with laravel and laravel/horizon for job scheudling. I've been looking into solutions on google - there doesn't seem to be either documentation or tutorials available, so I'm wondering if that's even possible?

I've found this: https://github.com/monospice/laravel-redis-sentinel-drivers, but this seems to only support up to Laravel 8, and no more.

I've tried setting up a connection like this:

config/database.php

   'client' => 'phpredis',
 
   'redis-sentinel' => [
   env('REDIS_SENTINEL_1'),
   env('REDIS_SENTINEL_2'),
   env('REDIS_SENTINEL_3'),
   'options' => [
      'replication' => 'sentinel',
      'service' => env('REDIS_SENTINEL_SERVICE', 'mymaster'),
      'parameters' => [
         'password' => env('REDIS_SENTINEL_PASSWORD', null),
         'database' => 0,
      ],
   ],
]

and using it, but it doesn't quite seem to work.

Any help or resources how to set it up properly would be greatly appreciated

You have to install predis package composer require predis/predis and add this driver configuration to your config/database.php file (on the same level with connections array)

    'connections' => [
           ...skipped....
           'redis' => [
               'driver' => 'redis'
           ]
     ],

    'redis' => [
        'client' => 'predis',

        // In this case default connection is for single redis instance
        'default' => [
            'host' => env('REDIS_HOST', 'localhost'),
            'password' => env('REDIS_PASSWORD', null),
            'port' => env('REDIS_PORT', 6379),
            'database' => 0,
        ],

        // We define sentinel connection for the HA cluster
        'sentinel' => [
            [
                'host' => env('REDIS_SENTINEL_HOST1', 'localhost'),
                'port' => env('REDIS_SENTINEL_PORT1', 26379),
                'timeout' => env('REDIS_CONNECT_TIMEOUT', 0.2)
            ],
            [
                'host' => env('REDIS_SENTINEL_HOST2', 'localhost'),
                'port' => env('REDIS_SENTINEL_PORT2', 26379),
                'timeout' => env('REDIS_CONNECT_TIMEOUT', 0.2)
            ],
            [
                'host' => env('REDIS_SENTINEL_HOST3', 'localhost'),
                'port' => env('REDIS_SENTINEL_PORT3', 26379),
                'timeout' => env('REDIS_CONNECT_TIMEOUT', 0.2)
            ],
            'options' => [
                'service' => env('REDIS_SENTINEL_SERVICE', 'mymaster'),
                'replication' => 'sentinel', 
                'password' => null,
                'parameters' => [
                    'database' => 0,
                ]
            ]
        ],

        // We can use different connection for cache
        'sentinel-cache' => [
            [
                'host' => env('REDIS_SENTINEL_HOST1', 'localhost'),
                'port' => env('REDIS_SENTINEL_PORT1', 26379),
                'timeout' => env('REDIS_CONNECT_TIMEOUT', 0.2)
            ],
            [
                'host' => env('REDIS_SENTINEL_HOST2', 'localhost'),
                'port' => env('REDIS_SENTINEL_PORT2', 26379),
                'timeout' => env('REDIS_CONNECT_TIMEOUT', 0.2)
            ],
            [
                'host' => env('REDIS_SENTINEL_HOST3', 'localhost'),
                'port' => env('REDIS_SENTINEL_PORT3', 26379),
                'timeout' => env('REDIS_CONNECT_TIMEOUT', 0.2)
            ],
            'options' => [
                'service' => env('REDIS_SENTINEL_SERVICE', 'mymaster'),
                'replication' => 'sentinel',
                'password' => null,
                'parameters' => [
                    'database' => 1,
                ]
            ],
        ]
    ]

Please notice that cache cleans the database periodicaly, so you must check that it is able to specify different redis connection in the database/cache.php:

'stores' => [
    ...skipped...

   'redis' => [
       'driver' => 'redis',
       'connection' => env('CACHE_CONNECTION','default')
   ]
]

so now you can use

SESSION_DRIVER=redis
SESSION_CONNECTION=sentinel
QUEUE_DRIVER=redis
QUEUE_CONNECTION=sentinel
CACHE_DRIVER=redis
CACHE_CONNECTION=sentinel-cache

as app environment variables
