Docker logs from file Mariadb Slow Queries Log

Question

I'm trying to make "MariaDB" container to log "Slow Queries". It works fine when MariaDB writes the log into a file. I have just to set a volume for that file and mount the volume to Filebeat.

But is there a way to make Docker log these entries into STDOUT or retrieve the logs from file? To not mount the volume into both MariaDB and Filebeat.

I tried to make a symlink to "/proc/self/fd/1" and run container with TTY, but MariaDB still can't use the symlink with error (Errcode: 29 "Illegal seek").
