Redis about docker-symfony HOT 1 CLOSED

Hello @benjaminjonard ,

If you are in the PHP container (docker-compose exec php bash), try to ping the redis container.
Here, is my result:

root@597b06d48146:/var/www/symfony# ping redis
PING redis (172.19.0.3): 56 data bytes
64 bytes from 172.19.0.3: icmp_seq=0 ttl=64 time=0.106 ms
64 bytes from 172.19.0.3: icmp_seq=1 ttl=64 time=0.070 ms
64 bytes from 172.19.0.3: icmp_seq=2 ttl=64 time=0.067 ms
64 bytes from 172.19.0.3: icmp_seq=3 ttl=64 time=0.077 ms
^C--- redis ping statistics ---
4 packets transmitted, 4 packets received, 0% packet loss
round-trip min/avg/max/stddev = 0.067/0.080/0.106/0.000 ms

So, redis host is reachable.
If you are using the SncRedisBundle, you have to fill the configuration file like this:

#config.yml
snc_redis:
    clients:
        default:
            type: predis
            alias: default
            dsn: redis://localhost

In my README.md, I use something like that (in the parameters.yml file):

# path/to/your/symfony-project/app/config/parameters.yml
parameters:
    redis_host: redis

So, you need to adapt the config file like this:

snc_redis:
    clients:
        default:
            # ...
            dsn: redis://%redis_host%

In my humble opinion, it's not a good idea to put the full IP address/dsn in a config file. This is why I was using the parameters.yml.

Kind regards,
