I'm trying to set up a LEMP stack in rkt (with Docker files), so I'm using Supervisord to get everything running in the same container. When I build and start the Mariadb container separately, it works fine. As soon as I try to run it via Supervisord instead, MariaDB exits right away. What am I doing wrong?
I want to use Supervisord for other things as well, so I'm sending this each time I run it:
RUN printf "\n[program:mysqld]\ncommand=sleep 5; mysqld_safe --skip-syslog\nstartretries=10\n" >> /etc/supervisor/conf.d/supervisord.conf
Sleep 5 and startretries I added for testing purposes.
The error log looks like this:

Not a single error, it just starts to shut down.
Ideas?
