【備忘録】credentials.yml.encにdatabase設定を保存する

Last updated at Posted at 2018-06-05

はじめに

Rails5.2からcredentials.yml.encに機密情報を格納させることができるようになったので、databaseの設定を保存させてみました。

credentials.yml.enc

credentials.yml.encにdatabaseの設定を記述する

# credentials.yml.encをviで開く
$ EDITOR="vi" bin/rails credentials:edit
credentials.yml.enc
db:
  host:     xxxxx
  database: xxxxx
  username: xxxxx
  password: xxxxx

database.yml

database.ymlcredentials.yml.encに指定した値を利用するように設定する

config/database.yml
# 省略
production:
  <<: *default
  # 省略
  host:     <%= Rails.application.credentials.db[:host] %>
  database: <%= Rails.application.credentials.db[:database] %>
  username: <%= Rails.application.credentials.db[:username] %>
  password: <%= Rails.application.credentials.db[:password] %>

所感/宿題

  • master.keyを総当たりされると復号できてしまうので、publicリポジトリではやらないほうがいい
  • データベースが1つだけの環境であれば、credentials.yml.encに格納させておくのが楽ちん
  • データベースが複数ある環境での運用方法がわからない
