Capacity Blocks 用於機器學習工作負載

在啟動範本中指定容量區塊 (AWS CLI)

請使用以下 create-launch-template 命令，建立指定現有容量區塊保留 ID 的啟動範本。將每個使用者輸入預留位置替換為自己的資訊。

aws ec2 create-launch-template --launch-template-name my-template-for-capacity-block  \
  --version-description AutoScalingVersion1 --region us-east-2 \
  --launch-template-data file://config.json

config.json 的內容。

{
    "ImageId": "ami-04d5cc9b88example",
    "InstanceType": "p4d.24xlarge",
    "SecurityGroupIds": [
        "sg-903004f88example"
    ], 
    "KeyName": "MyKeyPair",
    "InstanceMarketOptions": {
        "MarketType": "capacity-block"
    },
    "CapacityReservationSpecification": {
        "CapacityReservationTarget": {
            "CapacityReservationId": "cr-02168da1478b509e0"
        }
    }
}

下列為範例輸出。

{
    "LaunchTemplate": {
        "LaunchTemplateId": "lt-068f72b724example",
        "LaunchTemplateName": "my-template-for-capacity-block",
        "CreateTime": "2023-10-27T15:12:44.000Z",
        "CreatedBy": "arn:aws:iam::123456789012:user/Bob",
        "DefaultVersionNumber": 1,
        "LatestVersionNumber": 1
    }
}

您可以使用下列 describe-launch-template-versions 命令，來驗證容量區塊保留 ID 是否與啟動範本關聯。

aws ec2 describe-launch-template-versions --launch-template-names my-template-for-capacity-block \
  --region us-east-2

下列是指定容量保留的啟動範本之範例輸出。

{
    "LaunchTemplateVersions": [
        {
            "LaunchTemplateId": "lt-068f72b724example",
            "LaunchTemplateName": "my-template-for-capacity-block",
            "VersionNumber": 1,
            "CreateTime": "2023-10-27T15:12:44.000Z",
            "CreatedBy": "arn:aws:iam::123456789012:user/Bob",
            "DefaultVersion": true,
            "LaunchTemplateData": {
                "ImageId": "ami-04d5cc9b88example",
                "InstanceType": "p5.48xlarge",
                "SecurityGroupIds": [
                    "sg-903004f88example"
                ], 
                "KeyName": "MyKeyPair",
                "InstanceMarketOptions": {
                    "MarketType": "capacity-block"
                },
                "CapacityReservationSpecification": {
                    "CapacityReservationTarget": {
                        "CapacityReservationId": "cr-02168da1478b509e0"
                    }
                }
            }
        }
    ]
