Why my Redis Docker container shows "(empty array)" for KEYS * while I'm absolutely sure it has cached data and it works OK

This is chunk of my docker-compose.yml:

  redis:
    image: redis:alpine
    container_name: foo_redis
    volumes:
      - ./docker/volumes/redis:/data
    restart: unless-stopped
    ports:
      - 6379:6379
    networks:
      - local_network

I can guarantee that data persists between ups and downs because I've defined volumes.

I can prove that data is being stored physically because I see dump.rdb within ./docker/volumes/redis on my host machine.

Then from my host machine I do:

docker exec -it foo_redis redis-cli

I get a prompt:

127.0.0.1:6379>

I type KEYS * and I get:

127.0.0.1:6379> KEYS *
(empty array)
127.0.0.1:6379>

Why? What am I doing wrong? Redis seems to works fine. My Laravel app has predis and caching works with no issues.

edit:

My .env looks like:

CACHE_DRIVER=redis
REDIS_CLIENT=predis
REDIS_HOST=redis
REDIS_PASSWORD=null
REDIS_PORT=6379

edit 2:

When I manually put something into redis, it shows only that thing.

127.0.0.1:6379> set hello world
OK
127.0.0.1:6379> get hello
"world"
127.0.0.1:6379> KEYS *
1) "hello"
127.0.0.1:6379>

The old answer, but maybe will be useful for someone, check the using Redis database number.

If your data contains in the Redis database with a number different from 0 (default number), first set the DB number in CLI mode, using the command SELECT <db number>

Example: https://redis.io/docs/manual/cli/#interactive-mode
