git hubにあるrailsアプリを、dockerで構築したrails環境で動かしたい
クローンするアプリ
ruby 2.2.2
rails 4.2.1
db postgresql
ローカル環境
$ docker -v
Docker version 20.10.7, build f0df350
$ docker-compose -v
docker-compose version 1.29.2, build 5becea4c
参考にしたこちらのドキュメント(Quickstart: Compose and Rails)では,ローカル環境にGemfile, Gemfile.lock, entrypoint.shを作り、Docker内にCOPYしていますが、私の場合git hubからクローンしたrails アプリを動かしたいので、そのアプリをdocker内にCOPYすればと考えました。
しかし、docker-compose build 後の、docker-compose up がうまくいかず行き詰っています。
FATAL: database "my_app_development" does not exist
とあることから、データベースの命名かどこか記述に誤りがあるかだと予想しております。
また、git hub上のアプリをdocker環境で動かす際の、正攻法をご存じでしたら教えていただけると幸いです。
まだdockerを触り始めて日が浅いため、稚拙なミスをしていると思いますが、なにとぞご教授願います。
