CircleCIで、RailsのRspecを実行したいが、rake db:createでエラーになる

CircleCIで、bitbuketへのpush時に、テストを自動で行いたいのですが、
bundle ecec rake db:createコマンド実行時に
"NoMethodError: undefined method `[]' for nil:NilClass"
と、エラーが出てしまいます。

エラーを検索してみても、解決策が見つからず。どこに原因があるのかも見当がつきません、、、
どなたか見当がつく方がいらっしゃいましたら、ご教授お願いいたします。

自己解決

こちら、Dockerで開発していたのですが、hostを、コンテナのエイリアスであるdbで指定していたため、エラーが起きていたようです、
database.ymlを以下のように変更

(省略)
test:
  <<: *default
  host: <%= ENV.fetch("POSTGRES_HOST") { 'db' } %>
  database: myapp_test

このようにしたら、無事に、CIが通りました！
