We have a new Symfony setup with Redis as the caching mechanism. We want to connect to a specific host, not the default localhost. In production, ./bin/console debug:dotenv gives the correct REDIS_HOST. This is configured in our .env and .env.local.php.
The error we get is:
Connection refused: tcp:127.0.0.1/6379
This is our configuration:
services.yml
services:
Redis:
# you can also use \RedisArray, \RedisCluster or \Predis\Client classes
class: \Predis\Client
calls:
- connect:
- '%env(REDIS_HOST)%'
- '%env(int:REDIS_PORT)%'
Symfony\Component\HttpFoundation\Session\Storage\Handler\RedisSessionHandler:
arguments:
- '@Redis'
- prefix: sp_ss_
- ttl: 1800
cache.yml
framework:
cache:
app: cache.adapter.redis
default_redis_provider: 'Redis'
pools:
site.cache:
adapter: cache.app
And our .env file:
APP_ENV=prod APP_SECRET=**** MESSENGER_TRANSPORT_DSN=redis://redis.local:6379/messages REDIS_HOST=redis.local REDIS_PORT=6379 REDIS_URL=redis://redis.local:6379

Symfony's documentation recommends using "calls -> connect", but only use it if you define your class as "Redis". When you use '\Predis\Client' you need to use the following settings:
"config/services.yaml"
Redis: # you can also use \RedisArray, \RedisCluster or \Predis\Client classes class: \Predis\Client # See all parameters here: https://github.com/predis/predis/wiki/Connection-Parameters#list-of-connection-parameters arguments: - host: '%env(REDIS_HOST)%' - port: '%env(int:REDIS_PORT)%' # uncomment the following if your Redis server requires a password # - password: '%env(REDIS_PASSWORD)%'I also used "\Predis\Client", after changing to "arguments" the connection worked here.
