Amazon Bedrock API キーを生成する

長期 Amazon Bedrock API キーを作成するには、 AWS Identity and Access Management API オペレーションを使用します。まず、前提条件を満たしていることを確認します。

前提条件

設定により、 が AWS 認証情報を自動的に認識 AWS CLI できることを確認します。詳細については、「 の設定の構成 AWS CLI」を参照してください。

ターミナルを開き、次のコマンドを実行します。

次のスクリプトを実行して、IAM ユーザーを作成し、Amazon Bedrock アクションを実行するためのアクセス許可をアタッチし、ユーザーに関連付ける長期的な Amazon Bedrock API キーを生成します。

import boto3
from datetime import datetime, timedelta

# Replace with name for your IAM user
username = "bedrock-api-user"
# Add any AWS-managed or custom policies that you want to the user
bedrock_policies = [
    "arn:aws:iam::aws:policy/AmazonBedrockLimitedAccess",        # Limited access
#    "arn:aws:iam::aws:policy/AmazonBedrockMarketplaceAccess",   # Optional: Access to Amazon Bedrock Marketplace actions
]
# Set the key expiration time to a number of your choice
expiration_time_in_days = 30

iam_client = boto3.client("iam")
    
# Create IAM user
user = iam_client.create_iam_user(username)

# Attach policies to user
for policy_arn in bedrock_policies:
    iam_client.attach_managed_policy(username, policy_arn)

# Create long-term Amazon Bedrock API key and return it
service_credentials = iam_client.create_service_specific_credential(
    user_name=username, 
    service_name="bedrock",
    credential_age_days=expiration_time_in_days
) 
api_key = service_credentials["ServiceApiKeyValue"]
print(api_key)

ターミナルを開き、次のコマンドを実行します。

pip install aws-bedrock-token-generator

ターミナルを開き、次のコマンドを実行します。

npm install @aws/bedrock-token-generator

Maven を使用する場合は、 に次の依存関係を追加しますpom.xml。

<dependency>
    <groupId>software.amazon.bedrock</groupId>
    <artifactId>aws-bedrock-token-generator</artifactId>
    <version>1.1.0</version>
</dependency>

Gradle を使用する場合は、 に以下を追加しますbuild.gradle。

token = provide_token()

// You can configure it to use other credential providers.
const provideToken = getTokenProvider();

async function example() {
    
  const token = await provideToken();

  // Use the token for API calls. The token has a default expiration of 12 hour.
  // If the expiresInSeconds parameter is specified during token creation, the 
  // expiration can be configured up to a maximum of 12 hours. However, the actual 
  // token validity period will always be the minimum of the requested expiration 
  // time and the AWS credentials' expiry time
  console.log(`Bearer Token: ${token}`);
}

BedrockTokenGenerator tokenGenerator = BedrockTokenGenerator.builder().build();
