Contoh AWS FIStemplate percobaan

Jika Anda menggunakan AWS FISAPIatau alat baris perintah untuk membuat template percobaan, Anda dapat membuat template di JavaScript Object Notation ()JSON. Untuk informasi selengkapnya tentang komponen templat eksperimen, lihatAWS FISkomponen template percobaan.

Untuk membuat eksperimen menggunakan salah satu contoh templat, simpan ke JSON file (misalnya,my-template.json), ganti nilai placeholder di italics dengan nilai Anda sendiri, dan kemudian jalankan create-experiment-templateperintah berikut.
