rails db を一から作り直したい

Question

困っていること

初学者です。
docker上で、Ruby On Rails のアプリケーションを開発しています。

migration周りをいじっていたら、dbが壊れたようでにっちもさっちも行かなくなりました。。
dbはmysqlです。

rails db:drop
rails db:create
rails db:migrate
の順で一から作り直そうとしましたが、それでもダメで、、

rails aborted!

Tasks: TOP => db:migrate

このようにエラーが出てしまいます。

完全にdbをリセットする方法は無いのでしょうか。。

#開発環境

ruby 2.5.3
rails 5.2.4
mysql 5.7

docker-compose.yml

version: '3'
services:
  db:
    image: mysql:5.7
    ports:
        - '2012:3306'
    environment:
        MYSQL_USER: root
        MYSQL_ROOT_PASSWORD: password
    volumes:
        - ./db/mysql/volumes:/var/lib/mysql
  web:
    image: rails:my_orav3
    command: bash -c "rm -f tmp/pids/server.pid && bundle exec rails s -p 3000 -b '0.0.0.0'"
    volumes:
      - .:/myapp
    environment:
      - TNS_ADMIN=./oracle_conf
      - TZ="Asia/Tokyo"
      - LANG=ja_JP.UTF-8
    ports:
      - "2102:3000"
    depends_on:
      - db

よろしくお願いします。。

Answer 1

mysql/を削除して、db：createすることで解決しました。

Answer 2

全部消えていい前提ならMySQLの再インストールですね。

docker-composeで開発環境を作っている場合は、どう再インストールするのでしょうか。。
コンテナを作り直すことでできますか。

dockerってはじめから全部入ってるんでしたっけ。それならdockerごと。
マイグレーションファイルとかはバックアップとっておいて。
