Delete a step scaling policy for Application Auto Scaling using the AWS CLI

When you no longer need a step scaling policy, you can delete it. To delete both the scaling policy and the associated CloudWatch alarm, complete the following tasks.

To delete your scaling policy

Use the delete-scaling-policy command.

Linux, macOS, or Unix

aws application-autoscaling delete-scaling-policy --service-namespace ecs \
  --scalable-dimension ecs:service:DesiredCount \
  --resource-id service/my-cluster/my-service \
  --policy-name my-step-scaling-policy

Windows

aws application-autoscaling delete-scaling-policy --service-namespace ecs ^
  --scalable-dimension ecs:service:DesiredCount ^
  --resource-id service/my-cluster/my-service ^
  --policy-name my-step-scaling-policy
To delete the CloudWatch alarm

Use the delete-alarms command. You can delete one or more alarms at a time. For example, use the following command to delete the Step-Scaling-AlarmHigh-ECS:service/my-cluster/my-service and Step-Scaling-AlarmLow-ECS:service/my-cluster/my-service alarms.

aws cloudwatch delete-alarms --alarm-name Step-Scaling-AlarmHigh-ECS:service/my-cluster/my-service Step-Scaling-AlarmLow-ECS:service/my-cluster/my-service
