# Metode untuk mengambil peran
<a name="id_roles_manage-assume"></a>

Sebelum pengguna, aplikasi, atau layanan dapat menggunakan peran yang Anda buat, Anda harus [memberikan izin untuk beralih ke](id_roles_use_permissions-to-switch.md) peran tersebut. Anda dapat menggunakan kebijakan apa pun yang dilampirkan ke grup atau pengguna untuk memberikan izin yang diperlukan. Setelah izin diberikan, pengguna dapat mengambil peran dari Konsol Manajemen AWS, Alat untuk Windows PowerShell, AWS Command Line Interface (AWS CLI) dan [https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html](https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html)API.

**penting**  
Saat Anda membuat program peran secara terprogram, alih-alih di konsol IAM, Anda memiliki opsi untuk menambahkan `Path` hingga 512 karakter selain `RoleName`, yang panjangnya dapat mencapai 64 karakter. Namun, jika Anda bermaksud menggunakan peran dengan fitur **Switch Role** di Konsol Manajemen AWS, maka gabungan `Path` dan `RoleName` tidak dapat melebihi 64 karakter.

Metode yang digunakan untuk mengambil peran menentukan siapa yang dapat mengambil peran dan berapa lama sesi peran dapat berlangsung. Saat menggunakan operasi `AssumeRole*` API, peran IAM yang Anda asumsikan adalah sumber daya. Pengguna atau peran yang memanggil operasi `AssumeRole*` API adalah prinsipnya.

Tabel berikut membandingkan metode untuk mengasumsikan peran.

¹ Menggunakan kredensi dari satu peran untuk mengambil peran yang berbeda disebut rantai [peran](id_roles.md#iam-term-role-chaining). Saat Anda menggunakan rantai peran, durasi sesi peran dibatasi hingga satu jam. Ini berlaku untuk peralihan Konsol Manajemen AWS peran AWS CLI, dan operasi API. Batasan ini tidak berlaku untuk asumsi awal peran dari kredenal pengguna, atau aplikasi yang berjalan di EC2 instans Amazon yang menggunakan profil instans.

² Pengaturan ini dapat memiliki nilai dari 1 jam hingga 12 jam. Untuk detail tentang pengubahan pengaturan durasi sesi maksimum, lihat [Manajemen peran IAM](id_roles_manage.md). Setelan ini menentukan durasi sesi maksimum yang dapat Anda minta saat Anda mendapatkan kredensial peran. Misalnya, saat Anda menggunakan [AssumeRole\$1](https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html) Operasi API untuk mengasumsikan peran, Anda dapat menentukan durasi sesi dengan menggunakan parameter `DurationSeconds`. Gunakan parameter ini untuk menentukan panjang durasi sesi peran mulai dari 900 detik (15 menit) hingga pengaturan durasi sesi maksimum untuk peran tersebut. Pengguna IAM yang beralih peran di konsol diberikan durasi sesi maksimum, atau sisa waktu dalam sesi pengguna mereka, mana yang lebih sedikit. Anggaplah Anda menetapkan durasi maksimum 5 jam dalam suatu peran. Pengguna IAM yang telah masuk ke konsol selama 10 jam (dari nilai maksimum standar 12) berganti peran. Durasi sesi peran yang tersedia adalah 2 jam. Untuk mempelajari cara melihat nilai maksimum untuk peran Anda, lihat [Memperbarui durasi sesi maksimum untuk peran](id_roles_update-role-settings.md#id_roles_update-session-duration) nanti di halaman ini.

**Catatan**  
Pengaturan durasi sesi maksimum tidak membatasi sesi yang diambil oleh layanan AWS .
Kredensi peran Amazon EC2 IAM tidak tunduk pada durasi sesi maksimum yang dikonfigurasi dalam peran.
Untuk memungkinkan pengguna untuk mengambil peran saat ini lagi dalam sesi peran, tentukan peran ARN atau Akun AWS ARN sebagai prinsipal dalam kebijakan kepercayaan peran. Layanan AWS yang menyediakan sumber daya komputasi seperti Amazon EC2, Amazon ECS, Amazon EKS, dan Lambda memberikan kredensi sementara dan secara otomatis memperbarui kredensional ini. Ini memastikan bahwa Anda selalu memiliki seperangkat kredensional yang valid. Untuk layanan ini, tidak perlu mengambil peran saat ini lagi untuk mendapatkan kredensi sementara. Namun, jika Anda berniat untuk meneruskan [tag sesi](id_session-tags.md) [atau kebijakan sesi](access_policies.md#policies_session), Anda perlu mengambil peran saat ini lagi. Untuk mempelajari cara memodifikasi kebijakan kepercayaan peran untuk menambahkan peran utama ARN atau Akun AWS ARN, lihat. [Memperbarui kebijakan kepercayaan peran](id_roles_update-role-trust-policy.md)

# Beralih dari pengguna ke peran IAM (konsol)
<a name="id_roles_use_switch-role-console"></a>

Anda dapat beralih peran saat masuk sebagai pengguna IAM, pengguna di Pusat Identitas IAM, peran federasi SAML, atau peran federasi identitas web. *Peran* menentukan sekumpulan izin yang dapat Anda gunakan untuk mengakses AWS sumber daya yang Anda butuhkan. Namun, Anda tidak masuk ke peran, tetapi setelah masuk sebagai pengguna IAM, Anda dapat beralih ke peran IAM. Sementara waktu ini mengesampingkan izin pengguna awal Anda dan justru memberikan izin yang ditetapkan untuk peran. Perannya bisa di akun Anda sendiri atau lainnya Akun AWS. Untuk informasi lebih lanjut tentang peran, keuntungannya, dan cara membuatnya, lihat [Peran IAM](id_roles.md), dan [Pembuatan peran IAM](id_roles_create.md).

Izin pengguna Anda dan peran apa pun yang Anda alihkan tidak bersifat kumulatif. Hanya satu rangkaian izin yang aktif pada satu waktu. Saat Anda beralih ke suatu peran, sementara Anda meninggalkan izin pengguna dan bekerja dengan izin yang diberikan ke peran tersebut. Saat Anda keluar dari peran, izin pengguna asli Anda dipulihkan secara otomatis.

Saat Anda beralih peran Konsol Manajemen AWS, konsol selalu menggunakan kredenal asli Anda untuk mengotorisasi sakelar. Misalnya, jika Anda beralih ke RoleA, IAM menggunakan kredensi asli Anda untuk menentukan apakah Anda diizinkan untuk mengasumsikan RoleA. Jika Anda kemudian beralih ke *RoleB saat Anda menggunakan RoleA, masih menggunakan kredensi asli **Anda** untuk* mengotorisasi sakelar AWS , bukan kredenal untuk RoleA.

**catatan**  
Saat Anda masuk sebagai pengguna di Pusat Identitas IAM, sebagai peran federasi SAML, atau sebagai peran federasi identitas web, Anda akan mengambil peran IAM saat memulai sesi. Misalnya, ketika pengguna di Pusat Identitas IAM masuk ke portal AWS akses, mereka harus memilih set izin yang berkorelasi dengan peran sebelum mereka dapat mengakses sumber daya. AWS 

## Sesi peran
<a name="id_roles_iam_user-switch-role-sessions"></a>

Saat Anda beralih peran, Konsol Manajemen AWS sesi Anda berlangsung selama 1 jam secara default. Sesi pengguna IAM adalah 12 jam secara default, pengguna lain mungkin memiliki durasi sesi yang berbeda yang ditentukan. Saat Anda beralih peran di konsol, Anda akan diberikan durasi sesi maksimum peran, atau sisa waktu dalam sesi pengguna, mana yang lebih sedikit. Anda tidak dapat memperpanjang durasi sesi dengan mengambil peran.

Misalnya, anggaplah durasi sesi maksimum 10 jam ditetapkan untuk peran. Anda telah masuk ke konsol selama 8 jam ketika Anda memutuskan untuk beralih ke peran. Ada 4 jam tersisa di sesi pengguna Anda, jadi durasi sesi peran yang diizinkan adalah 4 jam, bukan durasi sesi maksimum 10 jam. Tabel berikut menunjukkan cara menentukan durasi sesi untuk pengguna IAM saat berganti peran di dalam konsol.


| Waktu sesi pengguna IAM yang tersisa adalah... | Durasi sesi peran adalah... | 
| --- | --- | 
| Kurang dari durasi sesi maksimum peran | Waktu yang tersisa di sesi pengguna  | 
| Lebih dari durasi sesi maksimum peran | Nilai durasi sesi maksimum | 
| Setara dengan durasi sesi maksimum peran | Nilai durasi sesi maksimum (perkiraan) | 

Menggunakan kredensi dari satu peran untuk mengambil peran yang berbeda disebut rantai [peran](id_roles.md#iam-term-role-chaining). Saat Anda menggunakan rantai peran, durasi sesi dibatasi hingga satu jam, terlepas dari pengaturan durasi sesi maksimum yang dikonfigurasi untuk peran individual. Ini berlaku untuk peralihan Konsol Manajemen AWS peran AWS CLI, dan operasi API.

**catatan**  
Beberapa konsol AWS layanan dapat memperbarui sesi peran Anda secara otomatis ketika berakhir tanpa Anda mengambil tindakan apa pun. Beberapa mungkin akan meminta Anda memuat ulang halaman peramban untuk mengotentikasi ulang sesi Anda.

## Pertimbangan-pertimbangan
<a name="id_roles_iam_user-switch-role-considerations"></a>
+ Anda tidak dapat beralih peran jika Anda masuk sebagai Pengguna root akun AWS. 
+ Pengguna harus diberikan izin untuk beralih peran berdasarkan kebijakan. Untuk petunjuk, lihat [Berikan izin pengguna untuk beralih peran](id_roles_use_permissions-to-switch.md).
+ Anda tidak dapat mengganti peran Konsol Manajemen AWS ke peran yang membutuhkan [ExternalId](id_roles_common-scenarios_third-party.md#id_roles_third-party_external-id)nilai. Anda hanya dapat beralih ke peran tersebut dengan memanggil [https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html](https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html) API yang mendukung parameter `ExternalId`.

## Untuk beralih ke peran
<a name="id_roles_iam_user-switch-role-console-procedure"></a>

1. Ikuti prosedur masuk yang sesuai dengan tipe pengguna Anda seperti yang dijelaskan [di Masuk ke Konsol Manajemen AWS](https://docs.aws.amazon.com/signin/latest/userguide/how-to-sign-in.html) *Panduan AWS Sign-In Pengguna*.

1. Di Konsol Manajemen AWS, pilih nama pengguna Anda di bilah navigasi di kanan atas. Biasanya terlihat seperti ini: ***username*@ *account\$1ID\$1number\$1or\$1alias***.

1. Pilih salah satu metode berikut untuk beralih peran:
   + Pilih **Beralih peran**.
   + Jika Anda telah memilih untuk mendukung multi-sesi, pilih **Tambah sesi** dan pilih **Beralih** peran.
**catatan**  
Anda dapat masuk hingga lima identitas berbeda secara bersamaan dalam satu browser web di Konsol Manajemen AWS file. Untuk detailnya, lihat [Masuk ke beberapa akun](https://docs.aws.amazon.com/awsconsolehelpdocs/latest/gsg/multisession.html) di *Panduan Konsol Manajemen AWS Memulai*.

1. Pada halaman **Ganti Peran**, ketik nomor ID akun atau alias akun dan nama peran yang diberikan oleh administrator Anda.
**catatan**  
Jika administrator Anda membuat peran itu dengan sebuah jalur, seperti `division_abc/subdivision_efg/roleToDoX`, maka Anda harus mengetik jalur dan nama lengkap tersebut di kotak **Peran**. Jika Anda hanya mengetik nama peran, atau jika gabungan `Path` dan `RoleName` lebih dari 64 karakter, pergantian peran gagal. Ini adalah batasan cookie peramban yang menyimpan nama peran tersebut. Jika ini terjadi, hubungi administrator Anda dan minta mereka untuk mengurangi ukuran jalur dan nama peran.

1. (Opsional) Anda dapat memasukkan nama tampilan dan memilih warna tampilan yang akan menyoroti peran di bilah navigasi konsol.
   + Untuk **Nama tampilan**, ketik teks yang ingin Anda tampilkan di bilah navigasi sebagai pengganti nama pengguna Anda saat peran ini aktif. Ada saran nama, berdasarkan informasi akun dan peran, tetapi Anda dapat mengubahnya menjadi apa pun yang berarti bagi Anda. 
   + Untuk **warna Tampilan**, pilih warna untuk menyorot nama tampilan.

   Nama dan warna dapat membantu mengingatkan Anda saat peran ini aktif, yang mengubah izin Anda. Misalnya, untuk peran yang memberi Anda akses ke lingkungan pengujian, Anda dapat menentukan **Nama tampilan** dari **Test** dan pilih **Warna** hijau. Untuk peran yang memberi Anda akses ke produksi, Anda dapat menentukan **Nama tampilan** dari **Production** dan pilih merah sebagai **Warna**.

1. Pilih **Ganti Peran**. Nama tampilan dan warna menggantikan nama pengguna Anda pada bilah navigasi, dan Anda dapat mulai menggunakan izin yang diberikan peran tersebut kepada Anda.

1. Setelah Anda menyelesaikan tugas-tugas yang memerlukan peran IAM Anda dapat beralih kembali ke sesi awal Anda. Ini akan menghapus izin tambahan yang diberikan oleh peran dan mengembalikan Anda ke izin standar Anda.

   1. Di konsol IAM, pilih **Nama tampilan** peran Anda di bilah navigasi di kanan atas.

   1. Pilih **Beralih kembali**.

      Misalnya, anggap Anda masuk ke nomor akun `123456789012` menggunakan nama pengguna `Richard`. Setelah menggunakan peran `admin-role`, Anda ingin berhenti menggunakan peran dan kembali ke izin awal. **Untuk berhenti menggunakan peran, pilih peran **admin @ 123456789012**, lalu pilih Beralih kembali.**  
![\[Grafik menemukan fungsi Switch back untuk berhenti menggunakan peran IAM dan kembali ke pengguna asli.\]](http://docs.aws.amazon.com/id_id/IAM/latest/UserGuide/images/role-stop-using.png)

**Tip**  
Beberapa peran terakhir yang Anda gunakan muncul pada menu. Lain kali Anda ingin beralih ke salah satu peran itu, Anda cukup memilih peran yang Anda inginkan. Anda hanya perlu mengetikkan akun dan informasi peran secara manual jika peran tidak ditampilkan di menu.

# Beralih ke peran IAM ()AWS CLI
<a name="id_roles_use_switch-role-cli"></a>

*Peran* menentukan serangkaian izin yang dapat Anda gunakan untuk mengakses sumber daya AWS yang Anda perlukan. Dalam hal ini, ini mirip dengan [pengguna di AWS Identity and Access Management](https://docs.aws.amazon.com/IAM/latest/UserGuide/id.html) (IAM). Saat Anda masuk sebagai pengguna, Anda mendapatkan serangkaian izin tertentu. Namun, Anda tidak masuk ke sebuah peran, tetapi setelah masuk sebagai pengguna, Anda dapat beralih ke sebuah peran. Sementara waktu ini mengesampingkan izin pengguna awal Anda dan justru memberikan izin yang ditetapkan untuk peran. Perannya bisa di akun Anda sendiri atau lainnya Akun AWS. Untuk informasi lebih lanjut tentang peran, keuntungannya, dan cara membuatnya, lihat [Peran IAM](id_roles.md), dan [Pembuatan peran IAM](id_roles_create.md). Untuk mempelajari tentang berbagai metode yang dapat Anda gunakan untuk mengasumsikan peran, lihat [Metode untuk mengambil peran](id_roles_manage-assume.md).

**penting**  
Izin pengguna IAM Anda dan peran apa pun yang Anda asumsikan tidak bersifat kumulatif. Hanya satu rangkaian izin yang aktif pada satu waktu. Saat Anda mengasumsikan suatu peran, sementara waktu Anda meninggalkan izin pengguna dan bekerja dengan izin yang ditetapkan ke peran tersebut. Saat Anda keluar dari peran, izin pengguna asli Anda dipulihkan secara otomatis.

Anda dapat menggunakan peran untuk menjalankan AWS CLI perintah saat Anda masuk sebagai pengguna IAM. Anda juga dapat menggunakan peran untuk menjalankan AWS CLI perintah ketika Anda masuk sebagai [pengguna yang diautentikasi secara eksternal](id_roles_providers.md) ([SALL](id_roles_providers_saml.md) atau [OIDC](id_roles_providers_oidc.md)) yang sudah menggunakan peran. Selain itu, Anda dapat menggunakan peran untuk menjalankan AWS CLI perintah dari dalam instans Amazon EC2 yang dilampirkan ke peran melalui profil instance-nya. Anda tidak dapat mengambil peran saat masuk sebagai Pengguna root akun AWS.

[**Rantai peran**](id_roles.md#iam-term-role-chaining) — Anda juga dapat menggunakan rantai peran, yang menggunakan izin dari peran untuk mengakses peran kedua.

Secara default, sesi peran Anda berlangsung selama satu jam. Saat Anda mengasumsikan peran dengan menggunakan `assume-role*` operasi CLI, Anda dapat menentukan nilai untuk parameter `duration-seconds`. Nilai ini dapat berkisar dari 900 detik (15 menit) hingga pengaturan durasi sesi maksimum untuk peran tersebut. Jika Anda beralih peran di konsol, durasi sesi Anda dibatasi hingga maksimal satu jam. Untuk mempelajari cara melihat nilai maksimum untuk peran Anda, lihat [Memperbarui durasi sesi maksimum untuk peran](id_roles_update-role-settings.md#id_roles_update-session-duration). 

Saat Anda menggunakan rantai peran, kredensial baru Anda dibatasi hingga durasi maksimum satu jam. Jika Anda kemudian menggunakan parameter `duration-seconds` untuk memberikan nilai lebih dari satu jam, operasi gagal.

## Skenario contoh: Beralih ke peran produksi
<a name="switch-role-cli-scenario-prod-env"></a>

Bayangkan bahwa Anda adalah pengguna IAM untuk bekerja di lingkungan pengembangan. Dalam skenario ini, Anda terkadang perlu bekerja dengan lingkungan produksi pada baris perintah dengan [AWS CLI](https://aws.amazon.com/cli/). Anda sudah memiliki kredensial access key yang tersedia untuk Anda. Ini dapat berupa key pair akses yang ditetapkan untuk pengguna IAM standar Anda. Atau, jika Anda masuk sebagai prinsipal federasi SAFL atau OIDC, itu bisa menjadi access key pair untuk peran yang awalnya ditugaskan kepada Anda. Jika izin Anda saat ini memberi Anda kemampuan untuk mengambil peran IAM tertentu, maka Anda dapat mengidentifikasi peran tersebut dalam “profil” dalam file AWS CLI konfigurasi. Perintah tersebut kemudian dijalankan atas izin peran IAM yang ditentukan, bukan identitas awal. Perhatikan bahwa ketika Anda menentukan profil itu dalam sebuah AWS CLI perintah, Anda menggunakan peran baru. Dalam situasi ini, Anda tidak dapat menggunakan izin awal dalam akun pengembangan pada saat bersamaan. Alasannya adalah bahwa hanya satu rangkaian izin yang dapat berlaku pada satu waktu.

**catatan**  
Untuk tujuan keamanan, administrator dapat [meninjau AWS CloudTrail log](cloudtrail-integration.md#cloudtrail-integration_signin-tempcreds) untuk mengetahui siapa yang melakukan tindakan. AWS Administrator Anda mungkin akan meminta Anda menentukan identitas sumber atau nama sesi peran ketika Anda mengambil peran tersebut. Untuk informasi selengkapnya, lihat [`sts:SourceIdentity`](reference_policies_iam-condition-keys.md#ck_sourceidentity) dan [`sts:RoleSessionName`](reference_policies_iam-condition-keys.md#ck_rolesessionname).

**Untuk beralih ke peran produksi (AWS CLI)**

1. <a name="step-configure-default"></a>Jika Anda belum pernah menggunakan AWS CLI, maka Anda harus terlebih dahulu mengkonfigurasi profil CLI default Anda. Buka prompt perintah dan atur AWS CLI instalasi Anda untuk menggunakan kunci akses dari pengguna IAM Anda atau dari peran federasi Anda. Untuk informasi lebih lanjut, lihat [Mengonfigurasi AWS Command Line Interface](https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html#cli-quick-configuration) di *Panduan Pengguna AWS Command Line Interface *.

   Jalankan perintah [aws configure](https://docs.aws.amazon.com/cli/latest/reference/configure/) sebagai berikut:

   ```
   aws configure
   ```

   Saat diminta, berikan informasi berikut:

   ```
   AWS Access Key ID [None]: AKIAIOSFODNN7EXAMPLE
   AWS Secret Access Key [None]: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
   Default region name [None]: us-east-2
   Default output format [None]: json
   ```

1. Buat profil baru untuk peran dalam `.aws/config` file dalam Unix atau Linux, atau `C:\Users\USERNAME\.aws\config` file dalam Windows. Contoh berikut membuat sebuah profil bernama `prodaccess` yang beralih ke peran `ProductionAccessRole` dalam akun `123456789012`. Anda mendapatkan peran ARN dari administrator akun yang membuat peran tersebut. Ketika profil ini dipanggil, akan AWS CLI menggunakan kredensil `source_profile` untuk meminta kredensil untuk peran tersebut. Oleh karena itu, identitas direferensikan karena `source_profile` harus memiliki izin `sts:AssumeRole` untuk peran yang ditentukan dalam `role_arn`.

   ```
   [profile prodaccess]
       role_arn = arn:aws:iam::123456789012:role/ProductionAccessRole
       source_profile = default
   ```

1. Setelah Anda membuat profil baru, AWS CLI perintah apa pun yang menentukan parameter `--profile prodaccess` berjalan di bawah izin yang dilampirkan ke peran IAM, `ProductionAccessRole` bukan pengguna default.

   ```
   aws iam list-users --profile prodaccess
   ```

   Perintah ini berfungsi jika izin yang ditetapkan ke `ProductionAccessRole` mengaktifkan pencatuman pengguna di akun AWS saat ini.

1. Untuk kembali ke izin yang diberikan oleh kredensial asli Anda, jalankan perintah tanpa parameter `--profile`. AWS CLI Kembali menggunakan kredensil di profil default Anda, yang Anda konfigurasikan. [Step 1](#step-configure-default)

Untuk informasi selengkapnya, lihat [Mengasumsikan Peran](https://docs.aws.amazon.com/cli/latest/userguide/cli-roles.html) dalam *Panduan AWS Command Line Interface Pengguna*.

## Skenario contoh: Menginzinkan peran profil instans untuk beralih ke peran dalam akun lain
<a name="switch-role-cli-scenario-ec2-instance"></a>

Bayangkan Anda menggunakan dua Akun AWS, dan Anda ingin mengizinkan aplikasi yang berjalan pada instans Amazon EC2 untuk menjalankan [AWS CLI](https://aws.amazon.com/cli/)perintah di kedua akun. Anggap bahwa instans EC2 ada di akun `111111111111`. Instance tersebut menyertakan peran profil `abcd` instance yang memungkinkan aplikasi melakukan tugas Amazon S3 hanya-baca di bucket dalam akun `amzn-s3-demo-bucket1` yang sama. `111111111111` Namun, aplikasi tersebut juga harus diizinkan untuk mengambil peran lintas akun `efgh` untuk melakukan tugas di akun `222222222222`. Untuk melakukannya, peran profil instans EC2 `abcd` harus memiliki kebijakan izin berikut:

***Kebijakan izin peran akun 1111111111 `abcd`***

------

Untuk kemudian menjalankan AWS CLI perintah di akun`222222222222`, Anda harus memperbarui file konfigurasi CLI. Identifikasi peran `efgh` sebagai "profil" dan peran profil instans EC2 `abcd` sebagai "sumber kredensial" dalam file konfigurasi AWS CLI . Kemudian perintah CLI Anda dijalankan dengan izin peran `efgh`, bukan peran `abcd` asli.

**catatan**  
Untuk tujuan keamanan, Anda dapat menggunakan AWS CloudTrail untuk mengaudit penggunaan peran dalam akun. Untuk membedakan sesi peran ketika peran digunakan oleh prinsipal yang berbeda di log CloudTrail , Anda dapat menggunakan nama sesi peran. Ketika AWS CLI mengambil peran atas nama pengguna seperti yang dijelaskan dalam topik ini, nama sesi peran secara otomatis dibuat sebagai`AWS-CLI-session-nnnnnnnn`. Berikut *nnnnnnnn* adalah bilangan bulat yang mewakili waktu dalam waktu [epoch Unix](http://wikipedia.org/wiki/Unix_time) (jumlah detik sejak tengah malam UTC pada 1 Januari 1970). Untuk informasi selengkapnya, lihat [Referensi CloudTrail Acara](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/eventreference.html) di *Panduan AWS CloudTrail Pengguna*.

**Untuk mengizinkan peran profil instans EC2 beralih ke peran lintas akun (AWS CLI)**

1. Anda tidak perlu mengonfigurasi profil CLI default. Sebagai gantinya, Anda dapat memuat kredensial dari metadata profil instans EC2. Buat profil baru untuk peran dalam file `.aws/config`. Contoh berikut membuat profil `instancecrossaccount` yang beralih ke peran `efgh` dalam akun `222222222222`. Saat profil ini dipanggil, AWS CLI menggunakan kredensial metadata profil instans EC2 untuk meminta kredensial bagi peran tersebut. Karena itu, peran profil instans EC2 harus memiliki izin `sts:AssumeRole` ke peran yang ditentukan dalam `role_arn`.

   ```
   [profile instancecrossaccount]
   role_arn = arn:aws:iam::222222222222:role/efgh
   credential_source = Ec2InstanceMetadata
   ```

1. Setelah Anda membuat profil baru, AWS CLI perintah apa pun yang menentukan parameter `--profile instancecrossaccount` berjalan di bawah izin yang dilampirkan ke `efgh` peran di akun. `222222222222`

   ```
   aws s3 ls amzn-s3-demo-bucket2 --profile instancecrossaccount
   ```

   Perintah ini berfungsi jika izin yang ditetapkan ke `efgh` peran memungkinkan daftar pengguna saat ini Akun AWS.

1. Untuk kembali ke izin profil instans EC2 asli di akun `111111111111`, jalankan perintah CLI tanpa parameter `--profile`.

# Beralih ke peran IAM (Alat untuk Windows PowerShell)
<a name="id_roles_use_switch-role-twp"></a>

*Peran* menentukan serangkaian izin yang dapat Anda gunakan untuk mengakses sumber daya AWS yang Anda perlukan. Dalam hal ini, ini mirip dengan [pengguna di AWS Identity and Access Management](https://docs.aws.amazon.com/IAM/latest/UserGuide/id.html) (IAM). Saat Anda masuk sebagai pengguna, Anda mendapatkan serangkaian izin tertentu. Namun, Anda tidak masuk ke sebuah peran, tetapi setelah masuk, Anda dapat beralih ke sebuah peran. Sementara waktu ini mengesampingkan izin pengguna awal Anda dan justru memberikan izin yang ditetapkan untuk peran. Perannya bisa di akun Anda sendiri atau lainnya Akun AWS. Untuk informasi lebih lanjut tentang peran, keuntungannya, dan cara membuatnya, lihat [Peran IAM](id_roles.md), dan [Pembuatan peran IAM](id_roles_create.md).

**penting**  
Izin pengguna IAM Anda dan peran apa pun yang Anda asumsikan tidak bersifat kumulatif. Hanya satu rangkaian izin yang aktif pada satu waktu. Saat Anda beralih ke suatu peran, sementara Anda meninggalkan izin pengguna dan bekerja dengan izin yang diberikan ke peran tersebut. Saat Anda keluar dari peran, izin pengguna asli Anda dipulihkan secara otomatis.

Bagian ini menjelaskan cara berganti peran ketika Anda bekerja di baris perintah dengan AWS Tools for Windows PowerShell.

Bayangkan Anda memiliki akun di lingkungan pengembangan dan Anda sesekali perlu bekerja dengan lingkungan produksi di baris perintah menggunakan [Alat untuk Windows PowerShell](https://aws.amazon.com/powershell/). Anda sudah memiliki satu set kredensial access key yang tersedia untuk Anda. Ini dapat berupa akses key pair yang ditetapkan untuk pengguna IAM standar Anda. Atau, jika Anda masuk sebagai prinsipal federasi SAFL atau OIDC, mereka bisa menjadi access key pair untuk peran yang awalnya diberikan kepada Anda. Anda dapat menggunakan kredensial ini untuk menjalankan `Use-STSRole` cmdlet yang melewati ARN peran baru sebagai parameter. Perintah tersebut mengembalikan kredensial keamanansementara untuk peran yang diminta. Kemudian, Anda dapat menggunakan kredensial tersebut dalam menurunkan perintah PowerShell dengan izin peran untuk mengakses sumber daya dalam produksi. Saat menggunakan peran tersebut, Anda tidak dapat menggunakan izin pengguna dalam akun Pengembangan karena hanya satu rangkaian izin yang berlaku pada satu waktu.

**catatan**  
Untuk tujuan keamanan, administrator dapat [meninjau AWS CloudTrail log](cloudtrail-integration.md#cloudtrail-integration_signin-tempcreds) untuk mengetahui siapa yang melakukan tindakan. AWS Administrator Anda mungkin akan meminta Anda menentukan identitas sumber atau nama sesi peran ketika Anda mengambil peran tersebut. Untuk informasi selengkapnya, lihat [`sts:SourceIdentity`](reference_policies_iam-condition-keys.md#ck_sourceidentity) dan [`sts:RoleSessionName`](reference_policies_iam-condition-keys.md#ck_rolesessionname).

Perhatikan bahwa semua kunci akses dan token hanyalah contoh dan tidak dapat digunakan seperti yang ditunjukkan. Ganti dengan nilai yang sesuai dari lingkungan langsung Anda.

**Untuk beralih ke peran IAM (Alat untuk Windows PowerShell)**

1. Buka prompt PowerShell perintah dan konfigurasikan profil default untuk menggunakan kunci akses dari pengguna IAM Anda saat ini atau dari peran federasi Anda. Jika sebelumnya Anda telah menggunakan Alat untuk Windows PowerShell, maka ini kemungkinan sudah dilakukan. Perhatikan bahwa Anda dapat beralih peran hanya jika Anda masuk sebagai pengguna IAM, bukan. Pengguna root akun AWS

   ```
   PS C:\> Set-AWSCredentials -AccessKey AKIAIOSFODNN7EXAMPLE -SecretKey wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY -StoreAs MyMainUserProfile
   PS C:\> Initialize-AWSDefaults -ProfileName MyMainUserProfile -Region us-east-2
   ```

   Untuk informasi selengkapnya, lihat [Menggunakan AWS Kredensial](https://docs.aws.amazon.com/powershell/latest/userguide/specifying-your-aws-credentials.html) di *Alat AWS untuk PowerShell Panduan Pengguna*.

1. Untuk mendapatkan kredensial peran baru, jalankan perintah berikut untuk beralih ke peran `RoleName` dalam akun 123456789012. Anda mendapatkan peran ARN dari administrator akun yang membuat peran tersebut. Perintah ini mengharuskan Anda untuk juga memberikan nama sesi. Anda dapat memilih teks apa pun untuk itu. Perintah berikut meminta kredensial dan kemudian menangkap objek properti `Credentials` dari objek hasil yang dikembalikan dan menyimpannya dalam variabel `$Creds`.

   ```
   PS C:\> $Creds = (Use-STSRole -RoleArn "arn:aws:iam::123456789012:role/RoleName" -RoleSessionName "MyRoleSessionName").Credentials
   ```

   `$Creds` adalah objek yang sekarang berisi elemen `AccessKeyId`, `SecretAccessKey`, dan `SessionToken` yang Anda butuhkan dalam langkah-langkah berikut ini. Perintah sampel berikut ini menggambarkan nilai-nilai umum:

   ```
   PS C:\> $Creds.AccessKeyId
   AKIAIOSFODNN7EXAMPLE
   
   PS C:\> $Creds.SecretAccessKey
   wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
   
   PS C:\> $Creds.SessionToken
   AQoDYXdzEGcaEXAMPLE2gsYULo+Im5ZEXAMPLEeYjs1M2FUIgIJx9tQqNMBEXAMPLECvSRyh0FW7jEXAMPLEW+vE/7s1HRp
   XviG7b+qYf4nD00EXAMPLEmj4wxS04L/uZEXAMPLECihzFB5lTYLto9dyBgSDyEXAMPLE9/g7QRUhZp4bqbEXAMPLENwGPy

   PS C:\> $Creds.Expiration
   Thursday, June 18, 2018 2:28:31 PM
   ```

1. Untuk menggunakan kredensial ini untuk perintah berikutnya, sertakan mereka dengan parameter `-Credential`. Misalnya, perintah berikut menggunakan kredensial dari peran dan bekerja hanya jika peran tersebut diberik izin`iam:ListRoles` dan karenanya dapat menjalankan `Get-IAMRoles` cmdlet:

   ```
           PS C:\> get-iamroles -Credential $Creds
   ```

1. Untuk kembali ke kredensi asli Anda, cukup berhenti menggunakan `-Credentials $Creds` parameter dan izinkan PowerShell untuk kembali ke kredensil yang disimpan di profil default.

# Beralih ke peran IAM (AWS API)
<a name="id_roles_use_switch-role-api"></a>

*Peran* menentukan serangkaian izin yang dapat Anda gunakan untuk mengakses sumber daya AWS . Dalam hal itu, ini mirip dengan [Pengguna IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/id.html). Seorang kepala sekolah (orang atau aplikasi) mengambil peran untuk menerima izin sementara untuk melaksanakan tugas yang diperlukan dan berinteraksi dengan AWS sumber daya. Perannya bisa di akun Anda sendiri atau lainnya Akun AWS. Untuk informasi lebih lanjut tentang peran, keuntungannya, dan cara membuatnya, lihat [Peran IAM](id_roles.md), dan [Pembuatan peran IAM](id_roles_create.md). Untuk mempelajari tentang berbagai metode yang dapat Anda gunakan untuk mengasumsikan peran, lihat [Metode untuk mengambil peran](id_roles_manage-assume.md).

**penting**  
Izin pengguna IAM Anda dan peran apa pun yang Anda asumsikan tidak bersifat kumulatif. Hanya satu rangkaian izin yang aktif pada satu waktu. Saat Anda mengasumsikan suatu peran, sementara waktu Anda meninggalkan izin pengguna dan bekerja dengan izin yang ditetapkan ke peran tersebut. Saat Anda keluar dari peran tersebut, izin asli Anda akan dipulihkan secara otomatis.

Untuk mengambil peran, aplikasi memanggil operasi AWS STS [https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html](https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html)API dan meneruskan ARN peran yang akan digunakan. Operasi membuat sesi baru dengan kredensial sementara. Sesi ini memiliki izin yang sama dengan kebijakan berbasis identitas untuk peran tersebut. 

Saat Anda menelepon [https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html](https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html), Anda secara opsional dapat meneruskan [kebijakan sesi](access_policies.md#policies_session) inline atau terkelola. Kebijakan sesi adalah kebijakan lanjutan yang Anda teruskan sebagai parameter saat Anda membuat sesi kredensyal sementara secara terprogram untuk peran atau sesi pengguna gabungan. Anda dapat menyampaikan satu dokumen kebijakan sesi inline JSON menggunakan parameter `Policy`. Anda dapat menggunakan parameter `PolicyArns` untuk menentukan hingga 10 kebijakan sesi terkelola. Izin sesi yang dihasilkan adalah titik pertemuan antara kebijakan berbasis identitas entitas dan kebijakan sesi. Kebijakan sesi berguna saat Anda perlu memberikan kredensial sementara kepada orang lain. Anda dapat menggunakan kredensial sementara peran tersebut dalam panggilan API AWS berikutnya untuk mengakses sumber daya di akun yang memiliki peran tersebut. Anda tidak dapat menggunakan kebijakan sesi untuk memberikan lebih banyak izin daripada yang diizinkan oleh kebijakan berbasis identitas. Untuk mempelajari selengkapnya tentang cara AWS menentukan izin efektif suatu peran, lihat[Logika evaluasi kebijakan](reference_policies_evaluation-logic.md). 

![\[PermissionsWhenPassingRoles_Diagram\]](http://docs.aws.amazon.com/id_id/IAM/latest/UserGuide/images/role_passed_policy_permissions.png)


Anda dapat memanggil `AssumeRole` saat Anda masuk sebagai pengguna IAM, atau sebagai [pengguna terotentikasi secara eksternal](id_roles_providers.md) ([SAML](id_roles_providers_saml.md) atau [OIDC](id_roles_providers_oidc.md)) yang sudah menggunakan peran. Anda juga dapat menggunakan [*rantai peran*](id_roles.md#iam-term-role-chaining), yang menggunakan peran untuk mengasumsikan peran kedua. Anda tidak dapat mengambil peran saat masuk sebagai Pengguna root akun AWS.

Secara default, sesi peran Anda berlangsung selama satu jam. Saat Anda mengambil peran ini menggunakan operasi AWS STS [https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html](https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html)API, Anda dapat menentukan nilai untuk `DurationSeconds` parameter tersebut. Nilai ini dapat berkisar dari 900 detik (15 menit) hingga pengaturan durasi sesi maksimum untuk peran tersebut. Untuk mempelajari cara melihat nilai maksimum untuk peran Anda, lihat [Memperbarui durasi sesi maksimum untuk peran](id_roles_update-role-settings.md#id_roles_update-session-duration). 

Jika Anda menggunakan rantai peran, sesi Anda akan dibatasi hingga maksimum satu jam. Jika Anda kemudian menggunakan parameter `DurationSeconds` untuk memberikan nilai lebih dari satu jam, operasi gagal.

**catatan**  
Untuk tujuan keamanan, administrator dapat [meninjau AWS CloudTrail log](cloudtrail-integration.md#cloudtrail-integration_signin-tempcreds) untuk mengetahui siapa yang melakukan tindakan. AWS Administrator Anda mungkin akan meminta Anda menentukan identitas sumber atau nama sesi peran ketika Anda mengambil peran tersebut. Untuk informasi selengkapnya, lihat [`sts:SourceIdentity`](reference_policies_iam-condition-keys.md#ck_sourceidentity) dan [`sts:RoleSessionName`](reference_policies_iam-condition-keys.md#ck_rolesessionname).

Contoh kode berikut menunjukkan cara membuat pengguna dan mengambil peran.

**Awas**  
Untuk menghindari risiko keamanan, jangan gunakan pengguna IAM untuk otentikasi saat mengembangkan perangkat lunak yang dibuat khusus atau bekerja dengan data nyata. Sebaliknya, gunakan federasi dengan penyedia identitas seperti [AWS IAM Identity Center](https://docs.aws.amazon.com/singlesignon/latest/userguide/what-is.html).
+ Buat pengguna tanpa izin.
+ Buat peran yang memberikan izin untuk mencantumkan bucket Amazon S3 untuk akun tersebut.
+ Tambahkan kebijakan agar pengguna dapat mengambil peran tersebut.
+ Asumsikan peran dan daftar bucket S3 menggunakan kredensyal sementara, lalu bersihkan sumber daya.

  For information, see this documentation topic:

  https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/get-started.html

  This example performs these operations:

  1. Creates a user that has no permissions.
  2. Creates a role and policy that grants Amazon S3 permissions.
  3. Creates a role.
  4. Grants the user permissions.
  5. Gets temporary credentials by assuming the role.  Creates an Amazon S3 Service client object with the temporary credentials.
  6. Deletes the resources.

# Menggunakan peran IAM untuk memberikan izin ke aplikasi yang berjalan di instans Amazon EC2
<a name="id_roles_use_switch-role-ec2"></a>

Aplikasi yang berjalan pada instans Amazon EC2 harus menyertakan AWS kredensional dalam permintaan API. AWS Anda dapat meminta pengembang menyimpan AWS kredensitas langsung dalam instans Amazon EC2 dan mengizinkan aplikasi dalam hal itu untuk menggunakan kredenal tersebut. Tetapi pengembang kemudian harus mengelola kredensil dan memastikan bahwa mereka meneruskan kredensil dengan aman ke setiap instance dan memperbarui setiap instans Amazon EC2 ketika saatnya untuk memperbarui kredensialnya. Banyak pekerjaan tambahan.

Sebagai gantinya, Anda dapat dan harus menggunakan peran IAM untuk mengelola kredenal *sementara* untuk aplikasi yang berjalan pada instans Amazon EC2. Bila Anda menggunakan peran, Anda tidak perlu mendistribusikan kredenal jangka panjang (seperti kredenal masuk atau kunci akses) ke instans Amazon EC2. Sebagai gantinya, peran menyediakan izin sementara yang dapat digunakan aplikasi saat mereka melakukan panggilan ke AWS sumber daya lain. Saat meluncurkan instans Amazon EC2, Anda menentukan peran IAM untuk diasosiasikan dengan instans. Aplikasi yang berjalan pada instans kemudian dapat menggunakan kredensial sementara yang diberikan oleh peran untuk menandatangani permintaan API.

Menggunakan peran untuk memberikan izin ke aplikasi yang berjalan di instans Amazon EC2 memerlukan sedikit konfigurasi tambahan. Aplikasi yang berjalan pada instans Amazon EC2 diabstraksikan AWS oleh sistem operasi tervirtualisasi. Karena pemisahan ekstra ini, Anda memerlukan langkah tambahan untuk menetapkan AWS peran dan izin terkait ke instans Amazon EC2 dan membuatnya tersedia untuk aplikasinya. Langkah ekstra ini adalah pembuatan *[profil instance](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-ec2_instance-profiles.html)* yang dilampirkan ke instance. Profil instans berisi peran dan dapat memberikan kredensial sementara peran ke aplikasi yang berjalan pada instans. Kredensial sementara tersebut kemudian dapat digunakan dalam panggilan API aplikasi untuk mengakses sumber daya dan membatasi akses ke sumber daya yang ditentukan oleh peran tersebut saja.

**catatan**  
Hanya satu peran yang dapat ditetapkan ke instans Amazon EC2 sekaligus, dan semua aplikasi pada instans memiliki peran dan izin yang sama. Saat memanfaatkan Amazon ECS untuk mengelola instans Amazon EC2, Anda dapat menetapkan peran ke tugas Amazon ECS yang dapat dibedakan dari peran instans Amazon EC2 yang dijalankannya. Menetapkan setiap tugas peran selaras dengan prinsip akses yang paling tidak memiliki hak istimewa dan memungkinkan kontrol terperinci yang lebih besar atas tindakan dan sumber daya.  
Untuk informasi selengkapnya, lihat [Menggunakan peran IAM dengan tugas Amazon ECS](https://docs.aws.amazon.com/AmazonECS/latest/bestpracticesguide/security-iam-roles.html) di Panduan *Praktik Terbaik Amazon Elastic Container Service*.

Penggunaan peran dengan cara ini memiliki beberapa keuntungan. Karena kredensi peran bersifat sementara dan diperbarui secara otomatis, Anda tidak perlu mengelola kredensi, dan Anda tidak perlu khawatir tentang risiko keamanan jangka panjang. Selain itu, jika Anda menggunakan satu peran untuk beberapa instance, Anda dapat membuat perubahan pada satu peran tersebut dan perubahan tersebut menyebar secara otomatis ke semua instance. 

**catatan**  
Meskipun peran biasanya ditetapkan ke instans Amazon EC2 saat Anda meluncurkannya, peran juga dapat dilampirkan ke instans Amazon EC2 yang sedang berjalan. Untuk mempelajar cara melampirkan peran pada instans yang sedang berjalan, lihat [Peran IAM untuk Amazon EC2](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/iam-roles-for-amazon-ec2.html#attach-iam-role).

## Bagaimana cara kerja peran untuk instans Amazon EC2?
<a name="roles-usingrole-ec2instance-roles"></a>

Pada gambar berikut, pengembang menjalankan aplikasi pada instans Amazon EC2 yang memerlukan akses ke bucket S3 bernama. `amzn-s3-demo-bucket-photos` Administrator membuat peran `Get-pics` layanan dan melampirkan peran tersebut ke instans Amazon EC2. Peran ini mencakup kebijakan izin yang memberikan akses hanya-baca ke bucket S3 tertentu. Ini juga mencakup kebijakan kepercayaan yang memungkinkan instans Amazon EC2 untuk mengambil peran dan mengambil kredensi sementara. Saat aplikasi berjalan pada instans, itu menggunakan kredensial sementara peran untuk mengakses bucket foto. Administrator tidak perlu memberikan izin kepada developer untuk mengakses bucket foto, dan developer tidak perlu membagikan atau mengelola kredensial.

![\[Aplikasi pada instans Amazon EC2 yang mengakses sumber daya AWS\]](http://docs.aws.amazon.com/id_id/IAM/latest/UserGuide/images/roles-usingrole-ec2roleinstance.png)


1. Administrator menggunakan IAM untuk membuat peran **Get-pics**. Dalam kebijakan kepercayaan peran, administrator menetapkan bahwa hanya instans Amazon EC2 yang dapat mengambil peran tersebut. Dalam kebijakan izin peran, administrator menentukan izin hanya-baca untuk bucket `amzn-s3-demo-bucket-photos`.

1. Pengembang meluncurkan instans Amazon EC2 dan menetapkan peran `Get-pics` tersebut ke instance tersebut.
**catatan**  
Jika Anda menggunakan konsol IAM, profil instans dikelola untuk Anda dan sebagian besar transparan bagi Anda. Namun, jika Anda menggunakan API AWS CLI atau untuk membuat dan mengelola peran dan instans Amazon EC2, Anda harus membuat profil instans dan menetapkan peran tersebut sebagai langkah terpisah. Kemudian, saat Anda meluncurkan instans, Anda harus menentukan nama profil instans dan bukan nama peran.

1. Saat aplikasi berjalan, itu mendapatkan kredensial keamanan sementara dari [metadata instans](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-metadata.html) Amazon EC2, sebagaimana dijelaskan dalam [Mengambil Kredensial Keamanan dari Metadata Instans](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/iam-roles-for-amazon-ec2.html#instance-metadata-security-credentials). Ini adalah [kredensial keamanan sementara](id_credentials_temp.md) yang mewakili peran tersebut dan berlaku untuk periode waktu yang terbatas. 

   Dengan beberapa [AWS SDKs](https://aws.amazon.com/tools/), pengembang dapat menggunakan penyedia yang mengelola kredenal keamanan sementara secara transparan. (Dokumentasi untuk individu AWS SDKs menjelaskan fitur yang didukung oleh SDK tersebut untuk mengelola kredensional.)

   Atau, aplikasi bisa mendapatkan kredensi sementara langsung dari metadata instance instans Amazon EC2. Kredensial dan nilai terkait tersedia dari kategori `iam/security-credentials/role-name` (dalam hal ini, `iam/security-credentials/Get-pics`) metadata. Jika aplikasi mendapatkan kredensial dari metadata instans, itu dapat menyimpan kredensial tersebut.

1. Dengan menggunakan kredensial sementara yang diambil, aplikasi mengakses bucket foto. Karena kebijakan terlampir pada peran **Get-pics**, aplikasi memiliki izin hanya-baca. 

   Kredensi keamanan sementara yang tersedia pada instans secara otomatis diperbarui sebelum kedaluwarsa sehingga set yang valid selalu tersedia. Aplikasi hanya perlu memastikan bahwa itu mendapatkan serangkaian kredensial baru dari metadata instans sebelum metadata yang sedang digunakan kedaluwarsa. Dimungkinkan untuk menggunakan AWS SDK untuk mengelola kredensional sehingga aplikasi tidak perlu menyertakan logika tambahan untuk menyegarkan kredensialnya. Misalnya, membuat instan klien dengan Penyedia Kredensial Profil Instans. Namun, jika aplikasi mendapatkan kredensial keamanan sementara dari metadata instans dan sudah menyimpannya, itu akan mendapatkan rangkaian kredensial yang diperbarui setiap jam, atau setidaknya 15 menit sebelum rangkaian yang sedang digunakan kedaluwarsa. Waktu kedaluwarsa termasuk dalam informasi yang dikembalikan dalam kategori. `iam/security-credentials/role-name` 

## Izin yang diperlukan untuk menggunakan peran dengan Amazon EC2
<a name="roles-usingrole-ec2instance-permissions"></a>

Untuk meluncurkan instance dengan peran, pengembang harus memiliki izin untuk meluncurkan instans Amazon EC2 dan izin untuk meneruskan peran IAM.

Kebijakan contoh berikut memungkinkan pengguna untuk menggunakan Konsol Manajemen AWS untuk meluncurkan instance dengan peran. Kebijakan ini mencakup wildcard (`*`) untuk memungkinkan pengguna meneruskan peran apa pun dan melakukan tindakan Amazon EC2 yang terdaftar. `ListInstanceProfiles`Tindakan ini memungkinkan pengguna untuk melihat semua peran yang tersedia di Akun AWS.

**Example Contoh kebijakan yang memberikan izin kepada pengguna untuk menggunakan konsol Amazon EC2 untuk meluncurkan instans dengan peran.**

```

    "Version":"2012-10-17",		 	 	 
    "Statement": [
        {
            "Sid": "IamPassRole",
            "Effect": "Allow",
            "Action": "iam:PassRole",
            "Resource": "*",
            "Condition": {
                "StringEquals": {

                }
            }

            "Effect": "Allow",
            "Action": [
                "iam:ListInstanceProfiles",
                "ec2:Describe*",
                "ec2:Search*",
                "ec2:Get*"
            ],
            "Resource": "*"
        }
    ]
}
```

### Membatasi peran mana yang dapat diteruskan ke instans Amazon EC2 (menggunakan) PassRole
<a name="roles-usingrole-ec2instance-passrole"></a>

Anda dapat menggunakan `PassRole` izin untuk membatasi peran mana yang dapat diteruskan pengguna ke instans Amazon EC2 saat pengguna meluncurkan instance. Ini membantu mencegah pengguna menjalankan aplikasi yang memiliki izin lebih dari yang diberikan kepada pengguna—yaitu, agar dapat memperoleh hak istimewa yang ditingkatkan. Misalnya, bayangkan pengguna Alice hanya memiliki izin untuk meluncurkan instans Amazon EC2 dan bekerja dengan bucket Amazon S3, tetapi peran yang diteruskannya ke instans Amazon EC2 memiliki izin untuk bekerja dengan IAM dan Amazon DynamoDB. Dalam hal ini, Alice mungkin dapat meluncurkan instance, masuk ke dalamnya, mendapatkan kredensi keamanan sementara, dan kemudian melakukan tindakan IAM atau DynamoDB yang tidak dia otorisasi.

Untuk membatasi peran mana yang dapat diteruskan pengguna ke instans Amazon EC2, Anda membuat kebijakan yang mengizinkan `PassRole` tindakan tersebut. Anda kemudian melampirkan kebijakan ke pengguna (atau ke grup IAM milik pengguna) yang akan meluncurkan instans Amazon EC2. Di `Resource` elemen kebijakan, Anda mencantumkan peran atau peran yang diizinkan diteruskan pengguna ke instans Amazon EC2. Saat pengguna meluncurkan suatu instans dan mengaitkan peran dengannya, Amazon EC2 akan memeriksa apakah pengguna diizinkan untuk meneruskan peran tersebut. Tentu saja, Anda juga harus memastikan bahwa peran yang dapat diteruskan oleh pengguna tidak mencakup lebih banyak izin dari yang seharusnya dimiliki oleh pengguna.

**catatan**  
`PassRole` bukan merupakan tindakan API dengan cara yang sama seperti `RunInstances` atau `ListInstanceProfiles`. Sebagai gantinya, ini adalah izin yang AWS memeriksa setiap kali peran ARN diteruskan sebagai parameter ke API (atau konsol melakukan ini atas nama pengguna). Itu membantu administrator untuk mengontrol peran mana yang dapat diteruskan oleh pengguna yang mana. Dalam kasus ini, itu memastikan bahwa pengguna diizinkan untuk melampirkan peran tertentu ke instans Amazon EC2.

**Example Contoh kebijakan yang memberikan izin kepada pengguna untuk meluncurkan instans Amazon EC2 dengan peran tertentu**  
Kebijakan sampel berikut memungkinkan pengguna untuk menggunakan Amazon EC2 API untuk meluncurkan instans dengan peran. Elemen `Resource` menentukan Amazon Resource Name (ARN) dari peran. Dengan menentukan ARN, kebijakan memberi izin kepada pengguna untuk hanya meneruskan peran `Get-pics`. Jika pengguna mencoba menentukan peran yang berbeda saat meluncurkan suatu instans, tindakan tersebut gagal. Pengguna memang memiliki izin untuk menjalankan setiap instans, terlepas dari apakah mereka meneruskan suatu peran.

### Memungkinkan peran profil instans untuk beralih ke peran dalam akun lain
<a name="switch-role-ec2-another-account"></a>

Anda dapat mengizinkan aplikasi yang berjalan di instans Amazon EC2 untuk menjalankan perintah di akun lain. Untuk melakukan ini, Anda harus mengizinkan peran instans Amazon EC2 di akun pertama untuk beralih ke peran di akun kedua.

Bayangkan Anda menggunakan dua Akun AWS dan Anda ingin mengizinkan aplikasi yang berjalan pada instans Amazon EC2 untuk menjalankan [AWS CLI](https://aws.amazon.com/cli/)perintah di kedua akun. Asumsikan bahwa instans Amazon EC2 ada di akun. `111111111111` Instance tersebut menyertakan peran profil `abcd` instance yang memungkinkan aplikasi melakukan tugas Amazon S3 hanya-baca di bucket dalam akun `amzn-s3-demo-bucket1` yang sama. `111111111111` Namun demikian, aplikasi tersebut juga harus diizinkan untuk menjalankan `efgh` peran lintas akun untuk mengakses `amzn-s3-demo-bucket2` bucket Amazon S3 dalam akun `222222222222`.

![\[Diagram menunjukkan bagaimana pengembang meluncurkan instans Amazon EC2 dengan peran untuk mendapatkan akses ke foto di bucket Amazon S3.\]](http://docs.aws.amazon.com/id_id/IAM/latest/UserGuide/images/roles-instance-profile-cross-account.png)


Peran profil instans `abcd` Amazon EC2 harus memiliki kebijakan izin berikut untuk mengizinkan aplikasi mengakses bucket Amazon S3`amzn-s3-demo-bucket1`:

## Bagaimana saya memulainya?
<a name="roles-usingrole-ec2instance-get-started"></a>

Untuk memahami cara kerja peran dengan instans Amazon EC2, Anda perlu menggunakan konsol IAM untuk membuat peran, meluncurkan instans Amazon EC2 yang menggunakan peran tersebut, lalu memeriksa instance yang sedang berjalan. Anda dapat menguji [metadata instans](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-metadata.html) untuk melihat bagaimana kredensial sementara peran tersedia untuk sebuah instans. Anda juga dapat melihat bagaimana aplikasi yang berjalan pada suatu instans dapat menggunakan peran tersebut. Gunakan sumber daya berikut ini untuk mempelajari lebih banyak. 
+ [Peran IAM di Tutorial Instans Amazon EC2](https://www.youtube.com/watch?v=TlCuOjviOhk). Video tertaut menunjukkan cara menggunakan peran IAM dengan instans Amazon EC2 untuk mengontrol apa yang dapat dilakukan aplikasi saat dijalankan pada instance. Video menunjukkan bagaimana aplikasi (ditulis dalam AWS SDK) bisa mendapatkan kredensi keamanan sementara melalui peran. 
+ Penelusuran SDK. Dokumentasi AWS SDK menyertakan penelusuran yang menunjukkan aplikasi yang berjalan pada instans Amazon EC2 yang menggunakan kredensi sementara untuk peran guna membaca bucket Amazon S3. Setiap penelusuran berikut menyajikan langkah serupa dengan bahasa pemrograman yang berbeda:

Ketika Anda kemudian menggunakan konsol Amazon EC2 untuk meluncurkan suatu instans dengan peran IAM, Anda dapat memilih peran untuk dikaitkan dengan isntans. Dalam konsol, daftar yang ditampilkan sebenarnya adalah daftar nama profil instance. Konsol tidak membuat profil instans untuk peran yang tidak terkait dengan Amazon EC2.

Anda dapat menggunakan Konsol Manajemen AWS untuk menghapus peran IAM dan profil instans untuk Amazon EC2 jika peran dan profil instans memiliki nama yang sama. Untuk mempelajari selengkapnya tentang menghapus profil instans, lihat [Hapus peran atau profil contoh](id_roles_manage_delete.md).

**catatan**  
Untuk memperbarui izin untuk sebuah instance, ganti profil instance-nya. Kami tidak menyarankan untuk menghapus peran dari profil instance, karena ada penundaan hingga satu jam sebelum perubahan ini berlaku.

## Mengelola profil instans (AWS CLI atau AWS API)
<a name="instance-profiles-manage-cli-api"></a>

Jika Anda mengelola peran Anda dari AWS CLI atau AWS API, Anda membuat peran dan profil instance sebagai tindakan terpisah. Karena peran dan profil instans dapat memiliki nama yang berbeda, Anda harus mengetahui nama profil instans Anda serta nama peran yang dimuat olehnya. Dengan begitu Anda dapat memilih profil instans yang benar saat Anda meluncurkan instans EC2. 

Anda dapat melampirkan tag ke sumber daya IAM Anda, termasuk profil instans, untuk mengidentifikasi, mengatur, dan mengontrol akses ke mereka. Anda dapat menandai profil instance hanya ketika Anda menggunakan AWS CLI atau AWS API. 

**catatan**  
Profil instans hanya dapat berisi satu peran IAM, meskipun peran dapat dimasukkan dalam beberapa profil instans. Batasan satu peran per profil instans ini tidak dapat ditingkatkan. Anda dapat menghapus peran yang ada dan kemudian menambahkan peran yang berbeda ke profil instans. Anda kemudian harus menunggu perubahan muncul di semua AWS karena [konsistensi akhirnya](https://en.wikipedia.org/wiki/Eventual_consistency). Untuk memaksa perubahan, Anda harus [memisahkan profil instans](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_DisassociateIamInstanceProfile.html) dan kemudian [mengaitkan profil instans](https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_AssociateIamInstanceProfile.html), atau Anda dapat menghentikan instance Anda lalu memulainya ulang.
