Verwenden Sie es CreateMaintenanceWindow mit einem oder AWS SDK CLI

Beispiel 1: Um ein Wartungsfenster zu erstellen

Im folgenden create-maintenance-window Beispiel wird ein neues Wartungsfenster erstellt, das alle fünf Minuten für bis zu zwei Stunden (je nach Bedarf) den Start neuer Aufgaben innerhalb einer Stunde nach Ende der Ausführung des Wartungsfensters verhindert, nicht zugeordnete Ziele (Instanzen, die Sie nicht für das Wartungsfenster registriert haben) zulässt und durch die Verwendung benutzerdefinierter Tags anzeigt, dass der Ersteller beabsichtigt, es in einem Tutorial zu verwenden.

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"

Ausgabe:

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

Beispiel 2: Um ein Wartungsfenster zu erstellen, das nur einmal ausgeführt wird

Im folgenden create-maintenance-window Beispiel wird ein neues Wartungsfenster erstellt, das nur einmal am angegebenen Datum und zur angegebenen Uhrzeit ausgeführt wird.

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"

Ausgabe:

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