# Gunakan `DeregisterScalableTarget` dengan CLI
Contoh kode berikut menunjukkan cara menggunakan`DeregisterScalableTarget`.
------
#### [ CLI ]
**AWS CLI**
**Untuk membatalkan pendaftaran target yang dapat diskalakan**
Contoh ini membatalkan pendaftaran target yang dapat diskalakan untuk layanan Amazon ECS yang disebut web-app yang berjalan di klaster default.
Perintah:
```
aws application-autoscaling deregister-scalable-target --service-namespace ecs --scalable-dimension ecs:service:DesiredCount --resource-id service/default/web-app
```
Contoh ini membatalkan pendaftaran target yang dapat diskalakan untuk sumber daya kustom. custom-resource-idFile.txt berisi string yang mengidentifikasi ID Sumber Daya, yang, untuk sumber daya kustom, adalah jalur ke sumber daya kustom melalui titik akhir Amazon API Gateway Anda.
Perintah:
```
aws application-autoscaling deregister-scalable-target --service-namespace custom-resource --scalable-dimension custom-resource:ResourceType:Property --resource-id file://~/custom-resource-id.txt
```

# Gunakan `PutScalingPolicy` dengan CLI
Contoh kode berikut menunjukkan cara menggunakan`PutScalingPolicy`.
------
#### [ CLI ]
**AWS CLI**
**Contoh 1: Untuk menerapkan kebijakan penskalaan pelacakan target dengan spesifikasi metrik yang telah ditentukan sebelumnya**
`put-scaling-policy`Contoh berikut menerapkan kebijakan penskalaan pelacakan target dengan spesifikasi metrik yang telah ditentukan sebelumnya ke layanan Amazon ECS yang disebut web-app di kluster default. Kebijakan tersebut menjaga pemanfaatan CPU rata-rata layanan pada 75 persen, dengan periode cooldown scale-out dan scale-in 60 detik. Output berisi ARNs dan nama dari dua CloudWatch alarm yang dibuat atas nama Anda.
```
aws application-autoscaling put-scaling-policy --service-namespace ecs \
--scalable-dimension ecs:service:DesiredCount \
--resource-id service/default/web-app \
--policy-name cpu75-target-tracking-scaling-policy --policy-type TargetTrackingScaling \
--target-tracking-scaling-policy-configuration file://config.json
```
Contoh ini mengasumsikan bahwa Anda memiliki file config.json di direktori saat ini dengan konten berikut:
```
{
"TargetValue": 75.0,
"PredefinedMetricSpecification": {
"PredefinedMetricType": "ECSServiceAverageCPUUtilization"
},
"ScaleOutCooldown": 60,
"ScaleInCooldown": 60
}
```
Output:
```
{
"PolicyARN": "arn:aws:autoscaling:us-west-2:012345678910:scalingPolicy:6d8972f3-efc8-437c-92d1-6270f29a66e7:resource/ecs/service/default/web-app:policyName/cpu75-target-tracking-scaling-policy",

"AlarmName": "TargetTracking-service/default/web-app-AlarmHigh-d4f0770c-b46e-434a-a60f-3b36d653feca"
},
{
"AlarmARN": "arn:aws:cloudwatch:us-west-2:012345678910:alarm:TargetTracking-service/default/web-app-AlarmLow-1b437334-d19b-4a63-a812-6c67aaf2910d",

}
```
**Contoh 2: Untuk menerapkan kebijakan penskalaan pelacakan target dengan spesifikasi metrik yang disesuaikan**
`put-scaling-policy`Contoh berikut menerapkan kebijakan penskalaan pelacakan target dengan spesifikasi metrik yang disesuaikan ke layanan Amazon ECS yang disebut web-app di kluster default. Kebijakan tersebut menjaga pemanfaatan rata-rata layanan pada 75 persen, dengan periode cooldown scale-out dan scale-in 60 detik. Output berisi ARNs dan nama dari dua CloudWatch alarm yang dibuat atas nama Anda.

}
]
}
```
**Contoh 3: Untuk menerapkan kebijakan penskalaan pelacakan target hanya untuk skala keluar**
`put-scaling-policy`Contoh berikut menerapkan kebijakan penskalaan pelacakan target ke layanan Amazon ECS yang dipanggil `web-app` di klaster default. Kebijakan ini digunakan untuk meningkatkan skala layanan ECS ketika `RequestCountPerTarget` metrik dari Application Load Balancer melebihi ambang batas. Outputnya berisi ARN dan nama CloudWatch alarm yang dibuat atas nama Anda.
```
aws application-autoscaling put-scaling-policy \
--service-namespace ecs \
--scalable-dimension ecs:service:DesiredCount \
--resource-id service/default/web-app \
--policy-name alb-scale-out-target-tracking-scaling-policy \
--policy-type TargetTrackingScaling \
--target-tracking-scaling-policy-configuration file://config.json
```
Isi dari `config.json`:
```
{
"TargetValue": 1000.0,
"PredefinedMetricSpecification": {
"PredefinedMetricType": "ALBRequestCountPerTarget",
"ResourceLabel": "app/EC2Co-EcsEl-1TKLTMITMM0EO/f37c06a68c1748aa/targetgroup/EC2Co-Defau-LDNM7Q3ZH1ZN/6d4ea56ca2d6a18d"
},
