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。
$ 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。$ 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。$ 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。$ 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:8080
。root
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_schema
、mysql
、performance_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_DATABASE
docker-compose.yml
test
init.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。
- 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?
- docker compose の初期 DB セットアップに関する問題
- docker-compose で実行されない mySQL 初期化スクリプト
- 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.
See the MariaDB Knowledgebase at https://mariadb.com/kb or the
MySQL manual for more instructions.
