目的
別の場所で docker で稼働している Redmine 環境を移行するための受け皿を作成したい。
そのためにまずは同じ環境を作成してみる。
実行ディレクトリを作成して移動
実行コマンド
sudo mkdir /usr/local/bin/redmine cd /usr/local/bin/redmine/
[root@test244 ~]# sudo mkdir /usr/local/bin/redmine [root@test244 ~]# [root@test244 ~]# cd /usr/local/bin/redmine/ [root@test244 redmine]# ls -al 合計 8 drwxr-xr-x. 2 root root 4096 10月 10 22:03 . drwxr-xr-x. 4 root root 4096 10月 10 22:03 .. [root@test244 redmine]#
docker-compose.yml を作成
実行コマンド
sudo vi /usr/local/bin/redmine/docker-compose.yml

表示できた。
参考
初期は以下の docker-compose.yml を使用していたが、コンテナが起動できなかった
docker-compose.yml
version: '3.7'
services:
redmine:
container_name: redmine-4.0.4
image: redmine:4.0.4-alpine
restart: always
ports:
- 8080:3000
volumes:

MYSQL_DATABASE: redmine
volumes:

command: mysqld --character-set-server=utf8 --collation-server=utf8_unicode_ci
docker-compose up -d コマンド実行後コンテナのステータスを確認。Restarting が実行され続けていた。。

docker-compose logs コマンドでログを確認したところ以下のログを確認。
redmine-db-4.0.4 | 2023-10-10 01:54:38+00:00 [Note] [Entrypoint]: Entrypoint script for MariaDB Server 1:11.1.2+maria~ubu2204 started. redmine-db-4.0.4 | 2023-10-10 01:54:38+00:00 [ERROR] [Entrypoint]: mariadbd failed while attempting to check config
上記のエラーログでググったところ以下の情報を確認。
2022年5月時点の docker 最新版で同様の事象が確認されていた。
https://stackoverflow.com/questions/72410663/error-starting-mariadb-on-docker-compose-build
情報によると image: mariadb でこの事象が発生するようで、対応としては image: mariadb:10.8.2 とすればとのこと。
そこで docker-compose.yml の redmine-db-4.0.4 側の image 設定を変更したところ正常に起動できた。
