Removes an ECS instance from a specified scaling group.
- When the ECS instance automatically created by the Auto Scaling service is removed from the scaling group, the ECS instance is disabled and released.
- When the manually attached ECS instance is removed from the scaling group, the ECS instance is neither disabled nor released.
- The interface can be called only when the scaling group is active.
- The interface can be called only when no scaling activity in the scaling group is in progress.
- When no scaling activity in the scaling group is in progress, the interface can be directly executed without cooldown.
- Successfully calling this interface only means that the Auto Scaling service has accepted the call request, and the scaling activity can be executed, but does not necessarily mean that the scaling activity can be successfully executed. You can use the returned ScalingActivityId to check the status of the scaling activity.
- When the total capacity of instances of the scaling group minus instances specified by this interface is smaller than than MinSize, the call fails.
