AlibabaCloudのROSからAuto ScalingでECSを起動してみる

More than 1 year has passed since last update.


はじめに

AlibabaCloudのAuto Scalingを触ってみる

からの、AlibabaCloudのAuto Scalingを

ROSで構築してみます。

Auto ScalingのResourceの部分を見てみる


ALIYUN::ESS::ScalingGroup

スケーリングのグループ管理になります。

インスタンスの個数(サイズ)を調整できます。

    "ScalingGroup": {

"Metadata": {
"GraphicId": "RosGraphicElement-12"
},
"Type": "ALIYUN::ESS::ScalingGroup",
"Properties": {
"VpcId": {
"Ref": "VPC"
},
"ScalingGroupName": "SSG",
"RemovalPolicys": [
"OldestScalingConfiguration",
"OldestInstance"
],
"MinSize": "2",
"MaxSize": "2",
"VSwitchId": {
"Ref": "VSwitch-ECS"
},
"DefaultCooldown": 300
}
},


ALIYUN::ESS::ScalingConfiguration

ECSインスタンスをどのように作るかになります。

    "ScalingConfiguration": {

"Metadata": {
"GraphicId": "RosGraphicElement-13"
},
"Type": "ALIYUN::ESS::ScalingConfiguration",
"Properties": {
"SystemDiskCategory": "cloud_ssd",
"InstanceType": {
"Ref": "InstanceType"
},
"SecurityGroupId": {
"Ref": "SG"
},
"ImageId": {
"Ref": "ImageId"
},
"InternetMaxBandwidthOut": 1,
"IoOptimized": "optimized",
"ScalingGroupId": {
"Ref": "ScalingGroup"
},
"InternetChargeType": "PayByTraffic",
"InternetMaxBandwidthIn": 200,
"ScalingConfigurationName": {
"Ref": "ALIYUN::StackName"
}
}
},


ALIYUN::ESS::ScalingGroupEnable

名前の通り、スケーリングの有効を管理します。

    "ScalingGroupEnable": {

"Metadata": {
"GraphicId": "RosGraphicElement-14"
},
"Type": "ALIYUN::ESS::ScalingGroupEnable",
"Properties": {
"ScalingConfigurationId": {
"Ref": "ScalingConfiguration"
},
"ScalingGroupId": {
"Ref": "ScalingGroup"
}
}
}


ROSから起動するとこのようになります。

さいごに

簡単にAutoScaling構成でECSが構築できました。

気づきましたでしょうか?

今回は、インスタンスタイプを

ecs.t5-lc2m1.nano

にしております。

AlibabaCloudのECSを東京リージョンの最安値で起動してみる!

の記事より、1台で起動するともっと安くなるはずです。
