#### [ CLI ]
**AWS CLI**
**Untuk menghapus grup target**
`delete-target-group`Contoh berikut menghapus kelompok target yang ditentukan.
```
aws elbv2 delete-target-group \
--target-group-arn arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-targets/73e2d6bc24d8a067
```
Perintah ini tidak menghasilkan output.
