解決Windows Docker 客戶端使用 Mariadb 官方image啟動報錯

MariaDB Image使用的是當前最新的v10.3版本

docker pull mariadb:latest

docker-compose.yml文件內容：

version: "3"
services:
  mariadb:
    image: mariadb
    container_name: mariadb
    restart: always
    volumes:
      - ${DATA_DIR}:/var/lib/mysql
    ports:
      - "3306:3306"
    environment:
      MYSQL_ROOT_PASSWORD: password
      MYSQL_DATABASE: public

.env 文件內容：

DATA_DIR=d:/data

容器起來後沒多久就掛掉重啟，查看log信息：

這個問題很多人已經遇到了，github上有很多討論，比如這個（ https://github.com/docker-library/mariadb/issues/38 ）還有這個（ https://github.com/laradock/laradock/issues/916 ）等，解決方法是在啟動容器的時候加一條命令 mysqld --innodb-flush-method=fsync。

最終在Windows Docker 可以正常運行的docker-compose.yml是：

version: "3"
services:
  mariadb:
    image: mariadb
    container_name: mariadb
    restart: always
    volumes:
      - ${DATA_DIR}:/var/lib/mysql
    ports:
      - "3306:3306"
    environment:
      MYSQL_ROOT_PASSWORD: password
      MYSQL_DATABASE: public
    command: 'mysqld --innodb-flush-method=fsync'

希望官方能夠在這之後的版本中解決這個問題。
