将 UpdateMaintenanceWindow 与 AWS SDK 或 CLI 配合使用

示例 1：更新维护时段

以下 update-maintenance-window 示例更新了维护时段的名称。

aws ssm update-maintenance-window \
    --window-id "mw-1a2b3c4d5e6f7g8h9" \
    --name "My-Renamed-MW"

输出：

{
    "Cutoff": 1,
    "Name": "My-Renamed-MW",
    "Schedule": "cron(0 16 ? * TUE *)",
    "Enabled": true,
    "AllowUnassociatedTargets": true,
    "WindowId": "mw-1a2b3c4d5e6f7g8h9",
    "Duration": 4
}

示例 2：禁用维护时段

以下 update-maintenance-window 示例禁用维护时段。

aws ssm update-maintenance-window \
    --window-id "mw-1a2b3c4d5e6f7g8h9" \
    --no-enabled

示例 3：启用维护时段

以下 update-maintenance-window 示例启用维护时段。

aws ssm update-maintenance-window \
    --window-id "mw-1a2b3c4d5e6f7g8h9" \
    --enabled
