Laravel 8 Sail Redis not assuming the default cache driver

[adellinocasas]

• Laravel Version: 8.38.0
• PHP Version: 8.0.3
• Database Driver & Version: N/A
• Environment: Sail (Docker)

Description:

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.

Please note:
dd(env('CACHE_DRIVER'));
shows "redis" .

Steps To Reproduce:

In terminal

docker exec -it laravel_sail-app_redis_1 redis-cli

(after: sail up)
This machine has no local Redis installation, not even MySQL, only PHP- this is a fresh Ubuntu installation . The app is served by Sail / Docker.

Everything stored with Redis facade - replicants of Redis commands - works well.

Thanks @driesvints good to know: there is no bug!!
It will be worth trying with a fresh app.
I've already post on Laracasts Forum and StackOverflow...

@adellinocasas, @piterog

• First, laravel uses different bases for Redis and Cache facades.
  See config/database.php redis.default and redis.cache
  
• Second, Laravel uses a prefix for Redis keys.
  See config/database.php redis.options.prefix
• Thirdly, the Cache facade uses a prefix for the key. Concatenate database.redis.options.prefix and cache.prefix
  See config/cache.php prefix

Finally

To view cache values change database and find keys:

127.0.0.1:6379[1]> SELECT 1;
127.0.0.1:6379[1]> KEYS *bar*
1) "laravel_database_laravel_cache:bar2"
2) "laravel_database_laravel_cache:bar3"

• laravel_database_ is database.redis.options.prefix
• laravel_cache: is cache.prefix
• bar2 your key
