# Use `CreateMaintenanceWindow` com um AWS SDK ou CLI
Os exemplos de código a seguir mostram como usar o `CreateMaintenanceWindow`.
Exemplos de ações são trechos de código de programas maiores e devem ser executados em contexto. É possível ver essa ação em contexto no seguinte exemplo de código:

#### [ CLI ]
**AWS CLI**
**Exemplo 1: criar uma janela de manutenção**
O exemplo de `create-maintenance-window` a seguir cria uma nova janela de manutenção que, a cada cinco minutos, e por até duas horas (conforme necessário), impede que novas tarefas sejam iniciadas dentro de uma hora do final da execução da janela de manutenção, permite destinos não associados (instâncias que você não registrou na janela de manutenção) e indica, por meio do uso de tags personalizadas, que seu criador pretende usá-la em um tutorial.
```
aws ssm create-maintenance-window \
--name "My-Tutorial-Maintenance-Window" \
--schedule "rate(5 minutes)" \
--duration 2 --cutoff 1 \
--allow-unassociated-targets \
--tags "Key=Purpose,Value=Tutorial"
```
Saída:
```
{
"WindowId": "mw-0c50858d01EXAMPLE"
}
```
**Exemplo 2: criar uma janela de manutenção que é executada somente uma vez**
O exemplo de `create-maintenance-window` a seguir cria uma nova janela de manutenção que só é executada uma vez na data e na hora especificadas.
```
aws ssm create-maintenance-window \
--name My-One-Time-Maintenance-Window \
--schedule "at(2020-05-14T15:55:00)" \
--duration 5 \
--cutoff 2 \
--allow-unassociated-targets \
--tags "Key=Environment,Value=Production"
```
Saída:
```
{
"WindowId": "mw-01234567890abcdef"
}
```
