CloudOps Orchestration Service:Criar um modelo

Crie um modelo personalizado no console do CloudOps Orchestration Service (OOS) para executar comandos em lote em várias instâncias ECS.

1. Faça logon no console do CloudOps Orchestration Service.

2. No painel de navegação à esquerda, escolha Automated Task > Custom Template e clique em Create Template.

3. Crie um modelo a partir de um modelo de exemplo ou de um arquivo local.

   • Nos modelos de exemplo, selecione Batch Run Commands e clique em Next Step.

   • Se você já tiver um arquivo de modelo YAML ou JSON para executar comandos em lote, carregue o arquivo local e clique em Next Step.

4. (Opcional) A tarefa Get ECS Instances vem pré-configurada. Para modificá-la, configure o parâmetro targets na seção Template Parameter.

   Nota

   Ao criar a execução, selecione as instâncias ECS nas quais os comandos serão executados e insira as informações necessárias. Para obter mais informações, consulte Create an execution.

5. Na área Command Content, edite o conteúdo do script e clique em Create Template.

6. Insira um Template Name e clique em OK.

• Após criar o modelo, inicie uma execução correspondente. Para obter mais informações, consulte Create an execution.

• Se você revisou todas as tarefas do modelo e aceita os riscos envolvidos, execute a operação sem confirmação manual. Para obter mais informações, consulte Fully automatic execution.

• Para executar tarefas individuais do modelo uma por vez, selecione o modo de etapa única ao criar a execução. Para obter mais informações, consulte Single-step execution.
