使用容量重新平衡来处理 Amazon EC2 竞价型实例中断

使用以下create-auto-scaling-group命令创建新的 Auto Scaling 组并启用容量重新平衡。该命令引用 JSON 文件作为自动扩缩组的唯一参数。

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

如果您还没有指定混合实例策略的 CLI 配置文件，请创建一个。

将以下行添加到配置文件中的顶级 JSON 对象。

{
    "CapacityRebalance": true
}

下面是一个 config.json 示例文件。

使用以下create-auto-scaling-group命令创建新的 Auto Scaling 组并启用容量重新平衡。该命令引用 YAML 文件作为自动扩缩组的唯一参数。

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

将以下行添加到 YAML 格式的配置文件。

CapacityRebalance: true
