こんにちは，しののめ(@Shinogasa)です．
仕事でDocker for Windows上にMySQLを立てていたのですが，都合によりMariaDBに移行することになりました．
そうしたら何か色々エラーが出て使えなかったのでその時の状況をメモ．
docker-compose使っていたので下記のような設定
#mysql:
# build: ./mysql
# volumes:
# - ./mysql/data:/var/lib/mysql
# ports:
# - 3306:3306
# environment:
# MYSQL_ROOT_PASSWORD: hoge
# MYSQL_DATABASE: fuga
mariadb:
build: ./mariadb
volumes:
- ./mariadb/data:/var/lib/mysql
ports:
- 3306:3306
environment:
MYSQL_ROOT_PASSWORD: hoge
MYSQL_DATABASE: fuga
mysqlの設定をそのままmariadbに書き換えただけ．
dockerfileはこう
FROM mariadb:latest EXPOSE 3306 CMD ["mysqld"]
ビルドして立ち上げてみたらこんなエラーが．

なんか再びエラーが．

これ見た感じだとDocker for WindowsではMariaDBが使えないっぽい？
というかMySQL立てた後にそのままMariaDB使うとダメなのかな．
色々試行錯誤してたらvolumesの値を/var/lib/mysqlから/var/lib/mariadbに変えたら問題なく起動してしまいました．
mariadb:
build: ./mariadb
volumes:
- ./mariadb/data:/var/lib/mariadb
ports:
- 3306:3306
environment:
MYSQL_ROOT_PASSWORD: hoge
MYSQL_DATABASE: fuga
dockerコンテナ上の同じディレクトリを使うとダメなのかもしれないっすね．
でもそのせいで今までMySQLに入れていたデータはMariaDBに引き継ぐことはできませんでした・・・．
やはりCentOS上にDocker立てるのが正解かもしれないですね．
