Laravel 8 and the dev environment is Sail - including Redis. The .env file:
CACHE_DRIVER=redis
..
REDIS_HOST=redis
REDIS_PASSWORD=null
REDIS_PORT=6379
Using the Redis facade functions, like
Redis::set( 'bar', 'The hole of the moon' );
using redis-cli is possible to find the value stored in cache
but using
Cache::put('bar2', 'baz', 100);
or even
Cache::store('redis')->put('bar3', 'Awesome', 100);
the values cannot be seen using the redis console
