将实例与自动扩缩组分离
此示例将指定实例与指定的自动扩缩组分离。
aws autoscaling detach-instances \ --instance-ids
i-030017cfa84b20135
\ --auto-scaling-group-namemy-asg
\ --should-decrement-desired-capacity输出:
{ "Activities": [ { "ActivityId": "5091cb52-547a-47ce-a236-c9ccbc2cb2c9", "AutoScalingGroupName": "my-asg", "Description": "Detaching EC2 instance: i-030017cfa84b20135", "Cause": "At 2020-10-31T17:35:04Z instance i-030017cfa84b20135 was detached in response to a user request, shrinking the capacity from 2 to 1.", "StartTime": "2020-04-12T15:02:16.179Z", "StatusCode": "InProgress", "Progress": 50, "Details": "{\"Subnet ID\":\"subnet-6194ea3b\",\"Availability Zone\":\"us-west-2c\"}" } ] }

示例 1:此示例将指定的实例与指定的自动扩缩组分离,并减少所需容量以使 Auto Scaling 不启动替换实例。
Dismount-ASInstance -InstanceId i-93633f9b -AutoScalingGroupName my-asg -ShouldDecrementDesiredCapacity $true
输出:
ActivityId : 06733445-ce94-4039-be1b-b9f1866e276e AutoScalingGroupName : my-asg Cause : At 2015-11-20T22:34:59Z instance i-93633f9b was detached in response to a user request, shrinking the capacity from 2 to 1. Description : Detaching EC2 instance: i-93633f9b Details : {"Availability Zone":"us-west-2b","Subnet ID":"subnet-5264e837"} EndTime : Progress : 50 StartTime : 11/20/2015 2:34:59 PM StatusCode : InProgress StatusMessage :
示例 2:此示例将在不减少所需容量的情况下将指定的实例与指定的自动扩缩组分离。Auto Scaling 会启动一个替换实例。
Dismount-ASInstance -InstanceId i-7bf746a2 -AutoScalingGroupName my-asg -ShouldDecrementDesiredCapacity $false
输出:
ActivityId : f43a3cd4-d38c-4af7-9fe0-d76ec2307b6d AutoScalingGroupName : my-asg Cause : At 2015-11-20T22:34:59Z instance i-7bf746a2 was detached in response to a user request. Description : Detaching EC2 instance: i-7bf746a2 Details : {"Availability Zone":"us-west-2b","Subnet ID":"subnet-5264e837"} EndTime : Progress : 50 StartTime : 11/20/2015 2:34:59 PM StatusCode : InProgress StatusMessage :
