Adds AWS Web Identity Token File (EKS IRSA) authentication support for Amazon Bedrock. ## Implementation - Detect `AWS_WEB_IDENTITY_TOKEN_FILE` environment variable to enable autoload - Conditionally set `credentialProvider` only when no bearer token exists - Maintain authentication precedence: bearer token → credential chain ## Changes - `provider.ts`: Conditional credentialProvider based on auth method - `amazon-bedrock.test.ts`: Add web identity token test + fix existing test cleanup - `auth.ts`, `providers.mdx`: Update documentation ## Verification Tested with real EKS IRSA credentials. All tests pass. No regressions in bearer token or access key authentication.

The following comment was made by an LLM, it may be inaccurate: Found Related PRPR #7502: feat(bedrock): support AWS_SHARED_CREDENTIALS_FILE for autoload Why it's related: This is a similar feature that adds AWS credential detection for Bedrock. While PR #8461 adds support for AWS Web Identity Token File (EKS IRSA), PR #7502 adds support for AWS_SHARED_CREDENTIALS_FILE. Both involve:
These appear to be complementary features rather than duplicates, both improving AWS authentication support for the Bedrock provider with different credential methods. |
