vagrantで起動したVM内で立ち上げているDockerのVolume（MySQLデータ永続化）で書き込みエラーになる件の対処

2021年6月9日

この記事は公開されてから1年以上経過しています。情報が古い可能性がありますので、ご注意ください。

vagrantで起動したVM内で立ち上げているDockerのVolume（データ永続化）でエラーになる件の対処についてメモしました。

エラーが発生した経緯

最近Dockerのアプリケーションを利用する際にVagrantで開発環境を構築することが多くあります。
その際にアプリケーションのリポジトリはホスト側へ配置しsynced_folderでVM内へデータを渡していています。
そしてそのsynced_folderで渡しているデータをさらにDockerのVolumeでコンテナへマウントしているという状態になっていてマウントの多段構成が発生しております。

そうなると発生するのが書き込みができないというエラーです。

環境

MariaDB 10.5.10
Docker 20.10.2
docker-compose1.25.0

発生したエラー

下記のdocker-composeで起動した際にエラーが発生します。

docker-compose.yml

docker-compose.ymlの内容になります。

docker-compose.ymlversion: '3'
services:
  mariadb:
    image: mariadb
    command: mysqld
    ports:
      - 3309:3306
    environment:
      MYSQL_DATABASE: sample_db
      MYSQL_ROOT_PASSWORD: root_passw0d
      MYSQL_USER: sample_user
      MYSQL_PASSWORD: sample_passw0d
    user: mysql
    volumes:
      - ./data:/var/lib/mysql

実行ログ

docker-compose up -dコマンドを実行したログになります。

mariadb_1  |     shell> /usr/bin/mysql_install_db --defaults-file=~/.my.cnf

mariadb_1  | You can also try to start the mysqld daemon with:
mariadb_1  | 
mariadb_1  |     shell> /usr/sbin/mysqld --skip-grant-tables --general-log &
mariadb_1  | 
mariadb_1  | and use the command line tool /usr/bin/mysql
mariadb_1  | to connect to the mysql database and look at the grant tables:
mariadb_1  | 
mariadb_1  |     shell> /usr/bin/mysql -u root mysql
mariadb_1  |     mysql> show tables;
mariadb_1  | 
mariadb_1  | Try 'mysqld --help' if you have problems with paths.  Using
mariadb_1  | --general-log gives you a log in /var/lib/mysql/ that may be helpful.

書き込みができないエラー

volumeへ設定した/var/lib/mysql/へ書き込みができないというエラーが発生しています。

swiftmysqld: Can't create/write to file '/var/lib/mysql/aria_log_control' (Errcode: 13 "Permission denied")

原因

コンテナ内のmysqlユーザがDBの設定をいこなう際に
データが書き込めないためエラーになっています。

解決手順

下記で記載していますが権限を合わせても解決できなかったため
データの永続化は名前付きボリュームにする形で解決しています。

docker-compose.ymlを修正

docker-compose.ymlversion: '3'
services:
  mariadb:
    image: mariadb
    command: mysqld
    ports:
      - 3309:3306
    environment:
      MYSQL_DATABASE: sample_db
      MYSQL_ROOT_PASSWORD: root_passw0d
      MYSQL_USER: sample_user
      MYSQL_PASSWORD: sample_passw0d
    volumes:
      - mysql-data:/var/lib/mysql
volumes:
  mysql-data:
    driver_opts:
      type: none
      device: /home/vagrant/data
      o: bind

volumeの作成

mysql-dataというvolumeを作成しています。

yamlvolumes:
  mysql-data:
    driver_opts:
      type: none
      device: /home/vagrant/data
      o: bind

データは/home/vagrant/dataへ保存させる設定を行っています。

volumeの設定

コンテナ側の/var/lib/mysqlに対して
作成したmysql-dataを設定しています。

kotlin    volumes:
      - mysql-data:/var/lib/mysql

再度コンテナを立ち上げ

docker-compose upコマンドで再度コンテナを立ち上げます。

terminal$ docker-compose up

mariadb_1  | 2021-06-09 04:08:34 0x7f194effd700  InnoDB: Assertion failure in file /home/buildbot/buildbot/build/mariadb-10.5.10/storage/innobase/os/os0file.cc line 3867
mariadb_1  | InnoDB: Failing assertion: cb->m_err == DB_SUCCESS
mariadb_1  | InnoDB: We intentionally generate a memory trap.
mariadb_1  | InnoDB: Submit a detailed bug report to https://jira.mariadb.org/
mariadb_1  | InnoDB: If you get repeated assertion failures or crashes, even
mariadb_1  | InnoDB: immediately after the mysqld startup, there may be
mariadb_1  | InnoDB: corruption in the InnoDB tablespace. Please refer to
mariadb_1  | InnoDB: https://mariadb.com/kb/en/library/innodb-recovery-modes/
mariadb_1  | InnoDB: about forcing recovery.

mariadb_1  | Installation of system tables failed!  Examine the logs in
mariadb_1  | /var/lib/mysql/ for more information.
mariadb_1  | 
mariadb_1  | The problem could be conflicting information in an external
mariadb_1  | my.cnf files. You can ignore these by doing:
mariadb_1  | 
mariadb_1  |     shell> /usr/bin/mysql_install_db --defaults-file=~/.my.cnf
mariadb_1  | 
mariadb_1  | You can also try to start the mysqld daemon with:
mariadb_1  | 
mariadb_1  |     shell> /usr/sbin/mysqld --skip-grant-tables --general-log &
mariadb_1  | 
mariadb_1  | and use the command line tool /usr/bin/mysql
mariadb_1  | to connect to the mysql database and look at the grant tables:
mariadb_1  | 
mariadb_1  |     shell> /usr/bin/mysql -u root mysql
mariadb_1  |     mysql> show tables;
mariadb_1  | 
mariadb_1  | Try 'mysqld --help' if you have problems with paths.  Using
mariadb_1  | --general-log gives you a log in /var/lib/mysql/ that may be helpful.
