Make it possible to configure database settings

[aldexxx86]

Make it possible to configure database settings that are usually found in the my.cnf file. For example I would like to be able to set the following setting: lower_case_table_names=0

Hy @aldexxx86,

you can do this by adding a volume entry to the database service like eg: - ${MYSQL_INITDB_DIR-./config/initdb/config/my.cnf}:/etc/my.cnf

at the end of the volumes section you need to add a command to allow it to run it in sql_mode

command: --sql_mode=""

rebuild the image and you should be good to go
