MariaDB slow query log

Hi,

I've enabled slow query log:

slow_query_log
slow_query_log_file=slow-queries.log
long_query_time=5.0

But I don't know where to find it.
I know that I can access the mariaDB container:

docker exec -it mariadb /bin/bash

but where is the file?

Thanks
Alex

its in /var/lib/mysql#
