Scheduled Auto Scaling: 指定時刻・定期的に自動でインスタンスを起動
2 notes
指定時刻に自動でインスタンスを起動させることを Scheduled Auto Scaling というみたい。as-describe-scheduled-actions で指定時刻にインスタンスを起動する必要があったため、コマンドのオプションを確認してみる。
（インスタンスの定義、グループの定義は完了しているものとする。）
Scheduled Auto Scaling 系のコマンドの種類
| コマンド | 説明 |
|---|---|
| as-descrive-scheduled-actions | スケジュールの確認 |
| as-put-scheduled-update-group-action | スケジュールの更新 |
| as-delete-scheduled-action | スケジュールの削除 |
コマンドの形式は as-describe-scheduled-actions [ScheduledActionNames [ScheduledActionNames ...] ] [--auto-scaling-group value ] [--end-time value ] [--max-records value ] [--start-time value] [General Options] で入力する。
Scheduled Auto Scaling を設定してみる
指定した時間（日本時間の 2013 年 02 月 07 日 19 時）にインスタンスを 3 台起動するスケジュール MyScheduleScaleOut1 を登録する。
// スケジュール登録
$ as-put-scheduled-update-group-action MyScheduleScaleOut1 --auto-scaling-group MyScaleGroup --time 2013-02-07T10:00:00Z --min-size 3 --max-size 7
// 確認
$ as-describe-scheduled-actions --headers
UPDATE-GROUP-ACTION GROUP-NAME NAME START-TIME MIN-SIZE MAX-SIZE
UPDATE-GROUP-ACTION MyScaleGroup MyScheduleScaleOut1 2013-02-07T10:00:00Z 3 7
登録されているスケジュール MyScheduleScaleOut1 を 最大 10 台起動するよう更新する。
// スケジュール修正
$ as-put-scheduled-update-group-action MyScheduleScaleOut1 --auto-scaling-group MyScaleGroup --time 2013-02-07T21:00:00Z --min-size 3 --max-size 10

定期的（日本時間の 21 時）にインスタンスを 2 台起動するスケジュール MyScheduleScaleOut2 を登録する。
// スケジュール登録
$ as-put-scheduled-update-group-action MyScheduleScaleOut2 --auto-scaling-group MyScaleGroup --name "scale out" --region ap-northeast-1 --recurrence "0 12 * * *" -min-size 2 -max-size 5

登録されているスケジュール MyScheduleScaleOut2 の時間を 21 時から 20 時に変更する。
// スケジュール修正
$ as-put-scheduled-update-group-action MyScheduleScaleOut2 --auto-scaling-group MyScaleGroup --name "scale out" --region ap-northeast-1 --recurrence "0 11 * * *" -min-size 2 -max-size 5

なぜか --reccurence 部分が更新されなかった。
ちゃんと反映させるべく、登録されているスケジュールを一旦削除して再登録する。
// スケジュール削除
$ as-delete-scheduled-action MyScheduleScaleOut2 --auto-scaling-group MyScaleGroup
Are you sure you want to delete this Scheduled Action? [Ny]y

value ] [--end-time value ] [--max-records value ] [--start-time value
] [General Options]
DESCRIPTION
Describes the specified scheduled actions, if the scheduled actions exist.
ARGUMENTS
ScheduledActionNames
Optional list of scheduled action names to be described.
If this list is omitted, all scheduled actions are described.
The list of requested scheduled actions cannot
contain more than 50 items. If an Auto Scaling
group name is provided, the results are limited to that group.
If unknown scheduled actions are requested, they are
ignored with no error.
SPECIFIC OPTIONS
--end-time VALUE
The latest scheduled start time that will be returned. If scheduled
action names are provided, this field will be ignored.
-g, --auto-scaling-group VALUE
No description available for this parameter.
--max-records VALUE
Maximum number of scheduled actions that will be described with each call
(default = 20, max = 50).
--start-time VALUE
The earliest scheduled start time that will be returned. If scheduled
action names are provided, this field will be ignored.

headers. For displaying XML results, it returns the HTTP headers from the
service request, if applicable. This is off by default.
