Simple MariaDB server on Alpine. The image tries to match UID & GID permission on local machine.

Start Container

 docker run --name mariadb \
    -p 3316:3306 \
    -v /var/lib/mysql:/var/lib/mysql \
    -v /var/log/mysql:/var/log/mysql \
    -v /etc/mysql:/etc/mysql \
    -h mariadb -d \

Command	Description
init	initialize directories if they're empty
bootstrap	create new database (calls init)
daemon	run in non-detached mode
start	start mariadb server
stop	quick mariadb shutdown (requires mysql-client)
kill	killall msyql

Auto Start Container

Bootstraping the server also yield 2 files install-systemd.sh and docker-mariadb.service they're located in where you map your directory to /etc/mysql. After configuration, check this directory and run install-systemd.sh it will use systemd.

This script is based on Docker's documentation on auto starting containers.

Installing the service by running:

./install-systemd.sh

Follow instruction. After everything looks good you can enable the service by running:

systemctl enable docker-mariadb.service
