作成時に docker db コンテナーがデータベースにデータセットを自動的に入力するようにしようとしています。mariadb documentationによるとdocker-entrypoint-initdb.d、ボリューム内にこの目的で使用できるフォルダーがあります。

StackOverflow で見つけたサンプルをミラーリングするようにファイルをセットアップしdocker-compose.ymlましたが、まだ SQL スクリプトを実行できません。私のdocker-compose.ymlファイルの関連部分は次のとおりです。

version: '3.6'
services:

  db:
    image: mariadb:10.5.4-focal
    container_name: db
    volumes:
      - ./cms/conf/mysql/data/:/var/lib/mysql/:rw
      - ./cms/sql/:/docker-entrypoint-initdb.d/:ro
    environment:
      - MYSQL_ROOT_PASSWORD=password
      - MYSQL_USER=root
      - MYSQL_PASSWORD=password
      - MYSQL_DATABASE=wordpress
    restart: always

  adminer:
    image: adminer:4.7.7-standalone
    container_name: adminer
    links:
      - db
    ports:
      - 8080:8080
    restart: always

docker-compose.ymlファイルの隣にcms/sql/init.sql、次の内容のファイルがあります。

CREATE DATABASE /*!32312 IF NOT EXISTS*/ `test` /*!40100 DEFAULT CHARACTER SET utf8mb4 */;
USE `test`;

各テストの繰り返しの前に、古い/キャッシュされた Docker コンテンツをクリーンアップします。

  1. $ docker-compose down -vこれは実際には db ボリュームを削除しないことがわかりました。静止画を実行すると、docker volume ls存在する過去のボリュームが表示されます。
  2. $ docker volume pruneこれにより、ボリュームがクリアされます。これを実行docker volume lsした後に実行すると、空のリストが表示されます。
  3. $ rm -rf ./cms/conf/mysqlこれにより、db コンテナーが行った実際のファイルシステムの変更が消去されます。
  4. $ docker-compose up -d --buildコンテナを再構築します。これにより、初期化 SQL スクリプトがトリガーされるはずです。

Docker が実行され、dbコンテナーが正常に作成されます。adminerで実行されているコンテナにアクセスできますlocalhost:8080rootファイルに指定されたパスワードを使用してユーザーとしてログインできdocker-compose.ymlます。

管理者インターフェイスには、標準の MySQL データベース ( information_schemamysqlperformance_schema) が表示され、さらにファイルの値でwordpress定義されたデータベースが表示されます。しかし、からの私のデータベースはどこにも見つかりません。MYSQL_DATABASEdocker-compose.ymltestinit.sql

同様の問題を抱えている他の同様の StackOverflow の質問を見つけました。受け入れられた回答に従いましたが、まだ SQL スクリプトを実行できません。

  1. docker-compose.yml、postgress、init.sql ファイルでデータベース、テーブル、プリポップをセットアップする方法は?
  2. docker compose の初期 DB セットアップに関する問題
  3. docker-compose で実行されない mySQL 初期化スクリプト
  4. docker-compose の起動時にデータベースを作成する

これが私のdbコンテナからの Docker ログです。奇妙に見えるものは何も見ませんでした。初期化などに関するエラーメッセージはありません:

PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !

To do so, start the server, then issue the following commands:


'/usr/bin/mysqladmin' -u root password 'new-password'

'/usr/bin/mysqladmin' -u root -h password 'new-password'


Alternatively you can run:

'/usr/bin/mysql_secure_installation'


which will also give you the option of removing the test

databases and anonymous user created by default. This is

strongly recommended for production servers.

MySQL manual for more instructions.
