Provides a MariaDB database server.

MariaDB 10.0 is compatible with MySQL 5.6.
MariaDB 10.1 is compatible with MySQL 5.6.
MariaDB 10.2 is compatible with MySQL 5.6/5.7.
MariaDB 10.3 is compatible with MySQL 5.7/8.0.
MariaDB 10.4 is compatible with MySQL 8.0.

The DB-Server is listening on TCP port 3306 by default.

The image also contains a healthcheck script at /usr/local/bin/healthcheck.sh.
This script can be used in a docker-compose.yaml file like this:

version: '3.5'
services:
  db:
    image: "db-mariadb-<ARCH>:<VERSION>"
    ports:
      - "3306:3306"
    volumes:
      - "$PWD/mpdata/mariadb/<VERSION>/intern:/var/lib/mysql"
      - "$PWD/mpdata/mariadb/<VERSION>/extern:/root/extDbFiles"
    environment:
      - CF_SYSUSR_MYSQL_USER_ID=<YOUR_UID>
      - CF_SYSUSR_MYSQL_GROUP_ID=<YOUR_GID>
      - CF_DB_ROOT_PASSWORD=<PASSWORD>
    healthcheck:
      test: ["CMD", "/usr/local/bin/healthcheck.sh"]
      interval: 30s
      timeout: 10s
      retries: 5
