CircleCi devise.secret_key was not set

Question

環境

rails 5.0.7
ruby 2.5.1
devise
Circleci 2

エラー

circleciの設定をしておりますが、おそらくci時にdeviseの環境変数が読み込めずciでエラーが起きてしまいます。
.circleci/config.ymlで、どのように環境変数を読み込ませるのでしょうか？

#!/bin/bash -eo pipefail
bin/rails db:schema:load --trace
** Invoke db:schema:load (first_time)
** Invoke environment (first_time)
** Execute environment

Devise.secret_key was not set. Please add the following to your Devise initializer:

CircleCiを触るのは初めてです。
もしわかるかたいらっしゃれば教えてください。

Answer 1

.gitignoreにsecrets.ymlを設定していた事が原因でした。

Answer 2

CIRCLE CI - プロジェクト内で環境変数を設定するこちらに書かれているように、コードに書きたくない値は、CircleCIの管理画面から環境変数を設定することができるので、このやり方がいいかなと思いました。
