### Memulai dengan Config
<a name="config_service_GettingStarted_053_bash_topic"></a>

Contoh kode berikut ini menunjukkan cara untuk melakukan:
+ Buat bucket Amazon S3.
+ Membuat topik Amazon SNS
+ Buat peran IAM untuk Config
+ Siapkan perekam konfigurasi Config
+ Siapkan saluran pengiriman Config
+ Mulai perekam konfigurasi
+ Verifikasi pengaturan Config

**AWS CLI dengan skrip Bash**  
 Ada lebih banyak tentang GitHub. Temukan contoh lengkapnya dan pelajari cara mengatur dan menjalankan di repositori [tutorial pengembang Sample](https://github.com/aws-samples/sample-developer-tutorials/tree/main/tuts/053-aws-config-gs).
