アクションと引数を定義するための構成設定

次の設定は、HeadNode/CustomActions/OnNodeStart & OnNodeConfigured & OnNodeUpdated および Scheduling/CustomActions/OnNodeStart & OnNodeConfigured アクションと引数を定義するために使用されます。

HeadNode:

Sequence の設定は AWS ParallelCluster バージョン 3.6.0 以降で追加されました。Sequence を指定すると、カスタムアクション用の複数のスクリプトを一覧表示できます。Sequence を追加しなくても、AWS ParallelCluster は 1 つのスクリプトによるカスタムアクションの設定を引き続きサポートします。

AWS ParallelCluster では、同じカスタムアクションで、単一のスクリプトと Sequence の両方を含めることはサポートされていません。例えば、次の設定を指定する場合、AWS ParallelCluster は失敗します。
