描述 EC2 实例集的配置、实例和事件历史记录

您可以描述 EC2 机群配置、EC2 机群中的实例，以及 EC2 机群的历史事件。

描述所有 EC2 实例集

使用 describe-fleets 命令描述所有 EC2 实例集。

aws ec2 describe-fleets

aws ec2 describe-fleets --fleet-ids fleet-8a22eee4-f489-ab02-06b8-832a7EXAMPLE

示例输出

{
    "Fleets": [
        {
            "ActivityStatus": "fulfilled",
            "CreateTime": "2022-02-09T03:35:52+00:00",
            "FleetId": "fleet-364457cd-3a7a-4ed9-83d0-7b63e51bb1b7",
            "FleetState": "active",
            "ExcessCapacityTerminationPolicy": "termination",
            "FulfilledCapacity": 2.0,
            "FulfilledOnDemandCapacity": 0.0,
            "LaunchTemplateConfigs": [
                {
                    "LaunchTemplateSpecification": {
                        "LaunchTemplateName": "my-launch-template",
                        "Version": "$Latest"
                    }
                }
            ],

                "DefaultTargetCapacityType": "spot"
            },
            "TerminateInstancesWithExpiration": false,
            "Type": "maintain",
            "ReplaceUnhealthyInstances": false,
            "SpotOptions": {
                "AllocationStrategy": "capacity-optimized",
                "InstanceInterruptionBehavior": "terminate"
            },
            "OnDemandOptions": {
                "AllocationStrategy": "lowestPrice"
            }
        }
    ]
}

描述指定 EC2 实例集中的所有实例

可以使用 describe-fleet-instances 命令描述指定 EC2 队列的实例。正在运行的实例的返回列表将定期刷新，或可能过时。

aws ec2 describe-fleet-instances  --fleet-id fleet-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE

示例输出

{
    "ActiveInstances": [
        {
            "InstanceId": "i-09cd595998cb3765e", 
            "InstanceHealth": "healthy", 
            "InstanceType": "m4.large", 
            "SpotInstanceRequestId": "sir-86k84j6p"
        }, 
        {
            "InstanceId": "i-09cf95167ca219f17", 
            "InstanceHealth": "healthy", 
            "InstanceType": "m4.large", 
            "SpotInstanceRequestId": "sir-dvxi7fsm"
        }
    ], 
    "FleetId": "fleet-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE"
}

描述 EC2 实例集的事件历史记录

可以使用 describe-fleet-history 命令描述指定 EC2 实例集在指定时间内的事件。有关输出中返回的事件的更多信息，请参阅 EC2 队列 事件类型。

aws ec2 describe-fleet-history \
    --fleet-id fleet-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE \
    --start-time 2018-04-10T00:00:00Z
