OpenStack Icehouse で Cloudify 2.7 を使用しています。
インスタンスを Apache Load Balancer に登録する Glassfish のサービス レシピを作成しました。
開始イベントはglassfish_start.groovy、次のコマンドを実行するファイルを実行します。
su - glassfish -c "asadmin --passwordfile /home/glassfish/passwd.gf --user $userAdmin start-domain $domain"
su - glassfish -c "asadmin --passwordfile /home/glassfish/passwd.gf --user $userAdmin deploy --contextroot \"/\" $warName"
開始イベントが終了すると、次のことがわかります。

停止検出が呼び出されたのはなぜですか?
さらに、Cloudify のドキュメントには次のように記載されています。
既知の制限: 開始スクリプトが返された場合、Cloudify はサービス インスタンスが停止したものとして扱い、再度プロビジョニングを試みます。この動作を回避するには、開始スクリプトが永久にスリープするようにしてください。
私は何をすべきか？
