[root@169_test mariadb10.3]# cat docker-compose.yml
version: '2'

services:
db:
image: mytest/mariadb10.3:latest
volumes:

  - ./db_data/:/var/lib/mysql/
restart: always
ports:
  - "3306:3306"

[root@169_test mariadb10.3]# docker-compose up
Creating network "mariadb103_default" with the default driver
Creating mariadb103_db_1 ... done
Attaching to mariadb103_db_1
db_1  | Installing MariaDB/MySQL system tables in '/var/lib/mysql' ...
db_1  | OK
db_1  |
db_1  | To start mysqld at boot time you have to copy
db_1  | support-files/mysql.server to the right place for your system
db_1  |
db_1  |
db_1  | PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
db_1  | To do so, start the server, then issue the following commands:
db_1  |
db_1  | '/usr/bin/mysqladmin' -u root password 'new-password'
db_1  | '/usr/bin/mysqladmin' -u root -h d56fe1b27eb9 password 'new-password'
db_1  |
db_1  | Alternatively you can run:
db_1  | '/usr/bin/mysql_secure_installation'
db_1  |
db_1  | which will also give you the option of removing the test
db_1  | databases and anonymous user created by default.  This is
db_1  | strongly recommended for production servers.
db_1  |
db_1  | See the MariaDB Knowledgebase at http://mariadb.com/kb or the
db_1  | MySQL manual for more instructions.
db_1  |
db_1  | You can start the MariaDB daemon with:
db_1  | cd '/usr' ; /usr/bin/mysqld_safe --datadir='/var/lib/mysql'
db_1  |
db_1  | You can test the MariaDB daemon with mysql-test-run.pl
db_1  | cd '/usr/mysql-test' ; perl mysql-test-run.pl
db_1  |
db_1  | Please report any problems at http://mariadb.org/jira
db_1  |
db_1  | The latest information about MariaDB is available at http://mariadb.org/.
db_1  | You can find additional information about the MySQL part at:
db_1  | http://dev.mysql.com
db_1  | Consider joining MariaDB's strong and vibrant community:
