CreateMaintenanceWindowOR와 함께 사용 AWS SDK CLI

예제 1: 유지 관리 기간을 생성하는 방법

다음 create-maintenance-window 예제에서는 필요한 경우 5분마다 최대 2시간 동안 유지 관리 기간 실행 종료 1시간 이내에 새 작업 시작을 방지하는 새 유지 관리 기간을 생성하고, 연결되지 않은 대상(유지 관리 기간에 등록되지 않은 인스턴스)을 허용하며, 생성자가 자습서에서 사용하려는 사용자 지정 태그 사용을 통해 이를 나타냅니다.

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"

출력:

{
    "WindowId": "mw-0c50858d01EXAMPLE"
}

예제 2: 한 번만 실행되는 유지 관리 기간을 생성하는 방법

다음 create-maintenance-window 예제에서는 지정된 날짜 및 시간에 한 번만 실행되는 새 유지 관리 기간을 생성합니다.

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"

출력:

{
    "WindowId": "mw-01234567890abcdef"
}
