4.2. Ruby を使用した API の例
以下の例では、Ruby を使用してさまざまなタスクを実行して Satellite API と通信する方法について説明します。
重要
以下は、スクリプトおよびコマンドの例です。以下のスクリプトを慎重にレビューしてから使用するようにしてください。変数、ユーザー名、パスワード、その他の情報は、お使いのデプロイメントに適した値に置き換えてください。
4.2.1. Ruby を使用したオブジェクトの作成
以下のスクリプトは Red Hat Satellite 6 API と接続して、新しい組織を作成し、その新規組織内に 3 つの環境を作成します。組織がすでに存在する場合には、スクリプトはその組織を使用します。組織内に環境が 1 つでも存在する場合は、スクリプトによりエラーが送出されて、スクリプトは終了します。
