+## Use Redis Cluster
+
+1 - First make sure you run the Redis-Cluster Container (`redis-cluster`) with the `docker-compose up` command.
+
+```bash
+docker-compose up -d redis-cluster
+```
+
+2 - Open your Laravel's `config/database.php` and set the redis cluster configuration. Below is example configuration with phpredis.
+
+Read the [Laravel official documentation](https://laravel.com/docs/5.7/redis#configuration) for more details.
+
+```php
+'redis' => [
+    'client' => 'phpredis',
+    'options' => [
+        'cluster' => 'redis',
+    ],
+    'clusters' => [
+        'default' => [
+            [
+                'host' => 'redis-cluster',
+                'password' => null,
+                'port' => 7000,
