no config file in redis

[bgeneto]

The redis docker container is supposed to read (and overwrite) settings available in /etc/redis.conf Problem is that, even if one make this file available - by mounting this file with docker-compose.yml, for example - this file is never read by the server as per cli command: redis-cli -p 6379 info server:

Note the empty config_file. Even if we replace the default file at /usr/share/defaults/etc/redis.conf with new options, the server does NOT honor the settings.
