Redis cache failure on Docker image

[clck-martin]

I just installed PLA from docker hub and configured Redis as cache.

Laravel is complaining about missing Redis class:

[2025-11-25 22:02:14] production.ERROR: Class "Redis" not found {"exception":"[object] (Error(code: 0): Class "Redis" not found at /app/vendor/laravel/framework/src/Illuminate/Redis/Connectors/PhpRedisConnector.php:80)

#44 /app/vendor/laravel/framework/src/Illuminate/Foundation/Http/Kernel.php(200): Illuminate\Routing\Router->dispatch()

Does anyone have had this issue? I have not found any instructions if the container has to be configured to install the Redis driver.

Please advise.

Thanks in advance
