By default for Laravel file cache if redis does not work

Question

In the “ monkey of chaos ” spirit, I’m trying to ensure that the laravel application continues to run even when the services on which it depends do not work.

It uses a database for primary storage and redis cache. I would like it to automatically return to the file cache if and when redis fails.

I could not find a clear example.

One way to solve this problem is to overwrite the default Laravel class Illuminate\Cache\CacheManager and change the ioc binding

 class MyCacheManager extends Illuminate\Cache\CacheManager { protected function createRedisDriver(array $config) { try { return parent::createRedisDriver($config); } catch (\Exception $e) { //Error with redis //Maybe there is a more explicit exception ;) return $this->resolve('file'); } } } 

In some ServiceProvider

 $this->app->singleton('cache', function($app) { return new MyCacheManager($app); }); 

This solution will also support the Cache facade :)

There seems to be a package for this: https://github.com/xtcat/laravel-redis-fallback

I have not yet found similar packages for sessions or queues. Please share this if anyone has.

Can you enable anonymous function instead of configuring cnfig cache driver?

which may try to use Redis, and if it fails to return the file as a parameter, and Redis if it succeeds
