示例 1：创建自动扩缩组

以下 create-auto-scaling-group 示例在区域内多个可用区中的子网中创建自动扩缩组。实例以指定启动模板的默认版本启动。请注意，大多数其他设置都使用默认值，例如，终止策略和运行状况检查配置。

aws autoscaling create-auto-scaling-group \
    --auto-scaling-group-name my-asg \
    --launch-template LaunchTemplateId=lt-1234567890abcde12 \
    --min-size 1 \
    --max-size 5 \
    --vpc-zone-identifier "subnet-5ea0c127,subnet-6194ea3b,subnet-c934b782"

此命令不生成任何输出。

有关更多信息，请参阅《Amazon EC2 Auto Scaling 用户指南》中的自动扩缩组。

示例 2：附加应用程序负载均衡器、网络负载均衡器或网关负载均衡器

此示例为支持预期流量的负载均衡器指定目标组的 ARN。运行状况检查类型指定 ELB，以便在 Elastic Load Balancing 报告实例运行状况不佳时，自动扩缩组将取代它。该命令还定义了以 600 秒为单位的运行状况检查宽限期。宽限期有助于防止新启动的实例过早终止。

aws autoscaling create-auto-scaling-group \
    --auto-scaling-group-name my-asg \
    --launch-template LaunchTemplateId=lt-1234567890abcde12 \
    --target-group-arns arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-targets/943f017f100becff \
    --health-check-type ELB \
    --health-check-grace-period 600 \
    --min-size 1 \
    --max-size 5 \
    --vpc-zone-identifier "subnet-5ea0c127,subnet-6194ea3b,subnet-c934b782"

此命令不生成任何输出。

有关更多信息，请参阅《Amazon EC2 Auto Scaling 用户指南》中的 Elastic Load Balancing 和 Amazon EC2 Auto Scaling。

示例 3：指定置放群组，并使用最新版本的启动模板

此示例将实例启动到单个可用区中的置放群组。这对于具有 HPC 工作负载的低延迟群组很有用。此示例还将指定群组的最小大小、最大大小和所需容量。

aws autoscaling create-auto-scaling-group \
    --auto-scaling-group-name my-asg \
    --launch-template LaunchTemplateId=lt-1234567890abcde12,Version='$Latest' \
    --min-size 1 \
    --max-size 5 \
    --desired-capacity 3 \
    --placement-group my-placement-group \
    --vpc-zone-identifier "subnet-6194ea3b"

此命令不生成任何输出。

有关更多信息，请参阅《适用于 Linux 实例的 Amazon EC2 用户指南》中的放置组。

示例 4：指定单个实例自动扩缩组，并使用特定版本的启动模板

此示例将创建一个自动扩缩组，并将其最小和最大容量均设置为 1 以强制运行一个实例。该命令还指定了启动模板的 v1，其中指定了现有 ENI 的 ID。当您使用为 eth0 指定现有 ENI 的启动模板时，必须为自动扩缩组指定与网络接口匹配的可用区，而无需在请求中同时指定子网 ID。

aws autoscaling create-auto-scaling-group \
    --auto-scaling-group-name my-asg-single-instance \
    --launch-template LaunchTemplateName=my-template-for-auto-scaling,Version='1' \
    --min-size 1 \
    --max-size 1 \
    --availability-zones us-west-2a

此命令不生成任何输出。

有关更多信息，请参阅《Amazon EC2 Auto Scaling 用户指南》中的自动扩缩组。

示例 5：指定不同的终止策略

此示例使用启动配置创建自动扩缩组，并将终止策略设置为首先终止最旧的实例。该命令还将标签应用于该组及其实例，其密钥为 Role，值为 WebServer。

aws autoscaling create-auto-scaling-group \
    --auto-scaling-group-name my-asg \
    --launch-configuration-name my-lc \
    --min-size 1 \
    --max-size 5 \
    --termination-policies "OldestInstance" \
    --tags "ResourceId=my-asg,ResourceType=auto-scaling-group,Key=Role,Value=WebServer,PropagateAtLaunch=true" \
    --vpc-zone-identifier "subnet-5ea0c127,subnet-6194ea3b,subnet-c934b782"

此命令不生成任何输出。

有关更多信息，请参阅《Amazon EC2 Auto Scaling 用户指南》中的使用 Amazon EC2 Auto Scaling 终止策略。

示例 6：指定启动生命周期挂钩

此示例将使用生命周期挂钩创建一个自动扩缩组，该挂钩支持在实例启动时的自定义操作。

aws autoscaling create-auto-scaling-group \
    --cli-input-json file://~/config.json

config.json 文件的内容：

{
    "AutoScalingGroupName": "my-asg",
    "LaunchTemplate": {
        "LaunchTemplateId": "lt-1234567890abcde12"
    },
    "LifecycleHookSpecificationList": [{
        "LifecycleHookName": "my-launch-hook",

        "NotificationMetadata": "SQS message metadata",
        "HeartbeatTimeout": 4800,
        "DefaultResult": "ABANDON"
    }],
    "MinSize": 1,
    "MaxSize": 5,
    "VPCZoneIdentifier": "subnet-5ea0c127,subnet-6194ea3b,subnet-c934b782",
    "Tags": [{
        "ResourceType": "auto-scaling-group",
        "ResourceId": "my-asg",
        "PropagateAtLaunch": true,
        "Value": "test",
        "Key": "environment"
    }]
}

此命令不生成任何输出。

示例 7：指定终止生命周期挂钩

此示例将使用生命周期挂钩创建一个自动扩缩组，该挂钩支持在实例终止时的自定义操作。

aws autoscaling create-auto-scaling-group \
    --cli-input-json file://~/config.json

config.json 的内容：

{
    "AutoScalingGroupName": "my-asg",
    "LaunchTemplate": {
        "LaunchTemplateId": "lt-1234567890abcde12"
    },
    "LifecycleHookSpecificationList": [{
        "LifecycleHookName": "my-termination-hook",
        "LifecycleTransition": "autoscaling:EC2_INSTANCE_TERMINATING",
        "HeartbeatTimeout": 120,
        "DefaultResult": "CONTINUE"
    }],
    "MinSize": 1,
    "MaxSize": 5,
    "TargetGroupARNs": [
        "arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-targets/73e2d6bc24d8a067"
    ],
    "VPCZoneIdentifier": "subnet-5ea0c127,subnet-6194ea3b,subnet-c934b782"
}

此命令不生成任何输出。

有关更多信息，请参阅 Amazon EC2 Auto Scaling 用户指南中的 Amazon EC2 Auto Scaling 生命周期挂钩。

示例 8：指定自定义终止策略

此示例将创建一个自动扩缩组，该组指定自定义 Lambda 函数终止策略，以指示 Amazon EC2 Auto Scaling 哪些实例可以安全地在横向缩减时终止。

aws autoscaling create-auto-scaling-group \
    --auto-scaling-group-name my-asg-single-instance \
    --launch-template LaunchTemplateName=my-template-for-auto-scaling \
    --min-size 1 \
    --max-size 5 \
    --termination-policies "arn:aws:lambda:us-west-2:123456789012:function:HelloFunction:prod" \
    --vpc-zone-identifier "subnet-5ea0c127,subnet-6194ea3b,subnet-c934b782"

此命令不生成任何输出。

此示例将删除指定的自动扩缩组。

aws autoscaling delete-auto-scaling-group \
    --auto-scaling-group-name my-asg

此命令不生成任何输出。

有关更多信息，请参阅《Amazon EC2 Auto Scaling 用户指南》中的删除自动扩缩基础设施。

示例 2：强制删除指定的自动扩缩组

要在不等待自动扩缩组中的实例终止的情况下删除该组，请使用 --force-delete 选项。

aws autoscaling delete-auto-scaling-group \
    --auto-scaling-group-name my-asg \
    --force-delete

此命令不生成任何输出。
