Mautic v. 4.4 and 5.X  
_My PHP version is_ : 8.0  
\*My MySQL/MariaDB version is: MySQL 5.7

**Updating/Installing Errors**  
_I am_ (delete as applicable): Installing  
_Upgrading/installing via_ (delete as applicable) : Web + Command Line

_These errors are showing in the installer_ : None

_These errors are showing in the Mautic log_ : None

**Your problem**  
I’m trying to setup Mautic in a docker container with Redis as a Cache backend.  
But I just can’t get Mautic to keep /var/cache empty and store any cache values in Redis.  
I have tried both version 4.4 and the latest 5.x

_Steps I have tried to fix the problem_:  
Installing with someting like this:  
git clone [GitHub - mautic/mautic: Mautic: Open Source Marketing Automation Software.](https://github.com/mautic/mautic.git)  
cd mautic  
composer install  
[Doing the rest of the install from the web interface]

Adding this to app/config/local.php:

…

```auto
// Cache
    'cache_adapter' => getenv("CACHE_ADAPTER") ?? "mautic.cache.adapter.redis",
    'cache_prefix' => getenv("CACHE_PREFIX") ?? "app_cache",
    'cache_lifetime' => getenv("CACHE_LIFETIME") ?? "86400",

```

```
'cache_adapter_redis' => [
    'dsn' => getenv("REDIS_DSN") ?? "redis://local-dev-redis",
    'options' => [
        'dbindex' => getenv("REDIS_OPTIONS_DBINDEX") ?? 0,
        'lazy' => getenv("REDIS_OPTIONS_LAZY") ?? false,
        'persistent' => getenv("REDIS_OPTIONS_PERSISTENT") ?? 0,
        'persistent_id' => getenv("REDIS_OPTIONS_PERSISTENT_ID") ?? null,
        'timeout' => getenv("REDIS_OPTIONS_TIMEOUT") ?? 30,
        'read_timeout' => getenv("REDIS_OPTIONS_READ_TIMEOUT") ?? 0,
        'retry_interval' => getenv("REDIS_OPTIONS_RETRY_INTERVAL") ?? 0,
        ]
    ],

```

```auto
ENVIRONMENT vars:
# 'local-dev-redis' is the name of the docker container

REDIS_DSN="redis://local-dev-redis"
REDIS_OPTIONS_DBINDEX="5"
REDIS_OPTIONS_LAZY="false"
REDIS_OPTIONS_PERSISTENT="0"
REDIS_OPTIONS_PERSISTENT_ID="null"
REDIS_OPTIONS_READ_TIMEOUT="0"
REDIS_OPTIONS_RETRY_INTERVAL="0"
REDIS_OPTIONS_TIMEOUT="30"

CACHE_ADAPTER="mautic.cache.adapter.redis"
CACHE_LIFETIME="86400"
CACHE_PREFIX="mautic_"

```

And finally clearing the cache:  
./bin/console cache:clear env=prod

And nothing shows up in redis and cache files piles up in /var/cache …

What is the proper way of doing this - how do you configure Mautic with Redis?
