As seguintes configurações são usadas para definir HeadNode / CustomActions / OnNodeStart & OnNodeConfigured & OnNodeUpdated e ações e argumentos Scheduling / CustomActions / OnNodeStart & OnNodeConfigured.

HeadNode:
  [...]
  CustomActions:
    OnNodeStart:
      # Script URL. This is run before any of the bootstrap scripts are run

Usando a Sequence configuração (adicionada na AWS ParallelCluster versão 3.6.0):

HeadNode:

            EnableWriteAccess: false

A Sequence configuração é adicionada a partir da AWS ParallelCluster versão 3.6.0. Ao especificarSequence, você pode listar vários scripts para uma ação personalizada. AWS ParallelCluster continua oferecendo suporte à configuração de uma ação personalizada com um único script, sem incluirSequence.

AWS ParallelCluster não suporta a inclusão de um único script e Sequence da mesma ação personalizada. Por exemplo, AWS ParallelCluster falhará se você especificar a configuração a seguir.
