Recommended docker-compose mariadb service

I recommend this service:

mariadb:
  image: mariadb:latest
  environment:
    - MYSQL_DATABASE=servicename
    - MYSQL_USER=servicename
    - MYSQL_PASSWORD=${MARIADB_PASSWORD}
    - MYSQL_ROOT_PASSWORD=${MARIADB_ROOT_PASSWORD}
  volumes:
    - ./mariadb_data:/var/lib/mysql
  command: --default-storage-engine innodb
  restart: unless-stopped
  healthcheck:
    test: mysqladmin -p${MARIADB_ROOT_PASSWORD} ping -h localhost
    interval: 20s
    start_period: 10s
    timeout: 10s
    retries: 3

(replace servicename by the name of your service, e.g. kimai, redmine, …) and this .env:

MARIADB_ROOT_PASSWORD=eiNgam3woh4ahTee4chi9vohvauk6a
MARIADB_PASSWORD=shahb4alubei5Vie8arahhok2morae
