Memberikan peran menggunakan library klien

Pelajari cara memulai metode IAM dari Resource Manager API dalam bahasa pemrograman favorit Anda.

Untuk mengikuti panduan langkah demi langkah untuk tugas ini langsung di Google Cloud konsol, klik Pandu saya:

Sebelum memulai

Buat Google Cloud project

Untuk panduan memulai ini, Anda memerlukan project Google Cloud baru.

Login ke akun Google Cloud Anda. Jika Anda baru menggunakan Google Cloud, buat akun untuk mengevaluasi performa produk kami dalam skenario dunia nyata. Pelanggan baru juga mendapatkan kredit gratis senilai $300 untuk menjalankan, menguji, dan men-deploy workload.

Instal Google Cloud CLI.

Jika Anda menggunakan penyedia identitas (IdP) eksternal, Anda harus login ke gcloud CLI dengan identitas gabungan Anda terlebih dahulu.

Untuk melakukan inisialisasi gcloud CLI, jalankan perintah berikut:

gcloud init

Buat atau pilih Google Cloud project.

Peran yang diperlukan untuk memilih atau membuat project

Pilih project: Memilih project tidak memerlukan peran IAM tertentu—Anda dapat memilih project mana pun yang telah diberi peran.
Membuat project: Untuk membuat project, Anda memerlukan peran Pembuat Project (roles/resourcemanager.projectCreator), yang berisi izin resourcemanager.projects.create. Pelajari cara memberikan peran.

Buat Google Cloud project:
```
gcloud projects create PROJECT_ID
```
Ganti PROJECT_ID dengan nama untuk Google Cloud project yang Anda buat.
Pilih project Google Cloud yang Anda buat:
```
gcloud config set project PROJECT_ID
```
Ganti PROJECT_ID dengan nama project Google Cloud Anda.

Aktifkan Resource Manager API:

Peran yang diperlukan untuk mengaktifkan API

Untuk mengaktifkan API, Anda memerlukan peran IAM Service Usage Admin (roles/serviceusage.serviceUsageAdmin), yang berisi izin serviceusage.services.enable. Pelajari cara memberikan peran.

gcloud services enable cloudresourcemanager.googleapis.com

Buat kredensial autentikasi lokal untuk akun pengguna Anda:

gcloud auth application-default login

Jika error autentikasi ditampilkan, dan Anda menggunakan penyedia identitas (IdP) eksternal, konfirmasi bahwa Anda telah login ke gcloud CLI dengan identitas gabungan Anda.

Memberikan peran ke akun pengguna Anda. Jalankan perintah berikut satu kali untuk setiap peran IAM berikut: roles/resourcemanager.projectIamAdmin

gcloud projects add-iam-policy-binding PROJECT_ID --member="user:USER_IDENTIFIER" --role=ROLE

Ganti kode berikut:

PROJECT_ID: Project ID Anda.
USER_IDENTIFIER: ID untuk akun pengguna Anda. Misalnya, myemail@example.com.
ROLE: Peran IAM yang Anda berikan ke akun pengguna Anda.

Membaca, mengubah, dan menulis kebijakan izin

Cuplikan kode dalam panduan memulai ini berfungsi sebagai berikut:

Melakukan inisialisasi layanan Resource Manager, yang mengelola project Google Cloud.
Membaca kebijakan izin untuk project Anda.
Mengubah kebijakan izin dengan memberikan peran Penulis Log (roles/logging.logWriter) ke Akun Google Anda.
Menulis kebijakan izin yang diperbarui.
Mencetak semua akun utama yang memiliki peran Penulis Log (roles/logging.logWriter) di level project.
Mencabut peran Penulis Log.

Ganti nilai berikut sebelum menjalankan cuplikan kode:

your-project: ID project Anda.
your-member: Alamat email untuk akun pengguna Anda. Contoh, user:my-user@example.com.

Selamat! Anda telah menggunakan metode IAM di Resource Manager API untuk mengubah akses suatu project.

Bagaimana hasilnya?

Pembersihan

Opsional: Cabut kredensial autentikasi yang Anda buat, dan hapus file kredensial lokal.
```
gcloud auth application-default revoke
```
Opsional: Cabut kredensial dari gcloud CLI.
```
gcloud auth revoke
```
