楽-travisはどのようにAWSにアクセスします

Travis CIにプロジェクトを連絡したところ、またエラーが発生しました.
.travis.ymlファイルを保存して押したが、同じエラーが発生した.

私が考えている理由かもしれません.

TravisはRDSにアクセスできないのでしょうか…?

どうしよう…
元々H 2と繋がっていたんですが….
RDSに近づけるべきですか?
パスワードがないからですか?ローカルでテストに合格しました...
本の次の章には解決方法があります...長い間うろうろしていた
の原因となる
外部サービスは通常AWSサービスにアクセスできません.
解決策
アクセス可能な鍵を生成して使用する必要があります.AWSがこれらの認証に関連する機能を提供するサービスはIAMである.
