ModifyInstanceAttribute - Auto Scaling

Modifies the information of an Elastic Compute Service (ECS) instance. When you call the ModifyInstanceAttribute operation, you can specify attributes such as the instance ID, scaling group ID, and region ID to modify the attributes of an ECS instance in a scaling group. You can modify only the hosting attributes of instances that are manually added to scaling groups.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

InstanceId	string	Yes	The ID of the ECS instance.	i-bp109k5j3dum1ce6****
ScalingGroupId	string	Yes	The ID of the scaling group.	asg-bp18p2yfxow2dloq****
Entrusted	boolean	No	Specifies whether to allow the scaling group to manage the lifecycles of the manually added ECS instances.

In this case, Auto Scaling releases the instances when they are removed from the scaling group. This rule does not apply to instances that are removed by calling the DetachInstances operation. false: does not allow the scaling group to manage the lifecycles of the manually added ECS instances. In this case, Auto Scaling does not release the instances when they are removed from the scaling group.
