public class ScalableTaskCount
extends BaseScalableAttribute

The scalable attribute representing task count.

Example:

 Cluster cluster;

         .cluster(cluster)
         .memoryLimitMiB(1024)
         .desiredCount(1)
         .cpu(512)
         .taskImageOptions(ApplicationLoadBalancedTaskImageOptions.builder()
                 .image(ContainerImage.fromRegistry("amazon/amazon-ecs-sample"))
                 .build())
         .build();
 ScalableTaskCount scalableTarget = loadBalancedFargateService.service.autoScaleTaskCount(EnableScalingProps.builder()
         .minCapacity(1)
         .maxCapacity(20)
         .build());
 scalableTarget.scaleOnCpuUtilization("CpuScaling", CpuUtilizationScalingProps.builder()
         .targetUtilizationPercent(50)
         .build());
 scalableTarget.scaleOnMemoryUtilization("MemoryScaling", MemoryUtilizationScalingProps.builder()
