This PR enables Jaeger to use AWS Managed Elasticsearch/OpenSearch for trace and metrics storage by adding SigV4 HTTP authentication support to Elasticsearch and OpenSearch backends.

Summary of changes

Configuration

  • Add jaeger_storage.backends.<name>.<elasticsearch|opensearch>.auth_extension.authenticator to reference an OpenTelemetry HTTP authenticator extension by name
  • Add jaeger_storage.metric_backends.<name>.<elasticsearch|opensearch>.auth_extension.authenticator for metric storage backends

Elasticsearch/OpenSearch backends

  • Thread the resolved HTTP authenticator through the factory chain (v1/v2 trace storage and metrics storage)
  • Wrap the HTTP RoundTripper used by ES/OS clients with the extension's RoundTripper (applies SigV4 signing when using sigv4authextension )
  • Updated GetHTTPRoundTripper() to accept and apply the HTTP authenticator

Configuration example

extensions:
sigv4auth:
region: us-east-1
service: es # or 'aoss' for OpenSearch Serverless
# credentials/assume-role configuration per the extension's documentation

service:
extensions: [sigv4auth]

jaeger_storage:
backends:
es-aws:
elasticsearch:
servers: ["https://my-domain.us-east-1.es.amazonaws.com/"]
auth_extension:
authenticator: sigv4auth
indices:
spans:
shards: 5
replicas: 1

metric_backends:
es-metrics:
elasticsearch:
servers: ["https://my-domain.us-east-1.es.amazonaws.com/"]
auth_extension:
authenticator: sigv4auth

Implementation

  • ES/OS backends now support optional HTTP authenticators via auth_extension.authenticator
  • The extension's RoundTripper wraps the base transport for SigV4 signing
  • Supports trace and metrics storage for Elasticsearch 7.x/8.x and OpenSearch

Scope

  • Adds authentication support to:
    • Elasticsearch trace storage (v1 and v2)
    • OpenSearch trace storage (v1 and v2)
    • Elasticsearch metrics storage
    • OpenSearch metrics storage
  • Backward compatible - authentication is optional

@yurishkuro This PR adds SigV4 authentication support for ES/OS backends (both trace and metric storage) by reusing the existing HTTP RoundTripper pattern. The smaller diff compared to #7520 is because ES/OS already has auth infrastructure, so I just threaded the httpAuth parameter through the factory chain. Let me know if you'd like any additional test coverage or have questions about the approach.

- Add AuthExtension field to ES/OS configuration

- Add AuthExtension field to Elasticsearch/OpenSearch configuration
- Implement getAuthenticator method in jaegerstorage extension
- Update factory chain (v1/v2/metrics) to accept httpAuth parameter
- Support authentication for both trace and metric storage
- Add test coverage for authenticator resolution
- Update all existing tests to handle new httpAuth parameter

This enables using OpenTelemetry HTTP authenticator extensions
(e.g., sigv4auth) with Elasticsearch and OpenSearch backends.
The authenticator is resolved from the host and wrapped into
the HTTP transport layer for secure AWS authentication.

The nil parameter passed to NewFactoryBase() should be replaced with the HTTP authenticator. The function signature has been updated to accept an authenticator parameter, but this call site is still passing nil, which means SigV4 authentication won't work when using this factory.

Consider updating this to pass the authenticator through, similar to how it's done in other factory implementations in this PR.

Keep Prometheus using Auth config (PR jaegertracing#7520 already merged).
ES/OS use new Authentication.AuthExtension pattern.
Wrapper approach preserves backward compatibility while allowing
all backends to share resolveAuthenticator helper internally.

Hi @yurishkuro,

I've refactored the implementation following your suggestion to embed configauth.Config in the Authentication struct. The changes are now much cleaner:

Changes made:

  • Embedded configauth.Config directly in the Authentication struct using the squash mapstructure tag
  • Removed the custom AuthExtensionConfig type entirely
  • Updated extension.go to access AuthenticatorID via cfg.Authentication.AuthenticatorID
  • Fixed test initialization to properly initialize the embedded struct

This follows the same pattern used in other OTel collector components and keeps the code simple.
could you please review again?

@yurishkuro Changes implemented!

Removed the AuthExtensionConfig and simplified the code as requested:

  • Pass Authentication struct directly to resolveAuthenticator
  • Eliminated all boilerplate wrapping code

The embedded configauth.Config with mapstructure:",squash" ensures the config structure matches OTEL pattern.

I don't see the need for this test. First, wantErr is always false, but more importantly what is it actually validating? This package has no knowledge of "extensions".

Fixed! Removed TestAuthExtensionConfig - you're right, it provided no real validation.
Authentication is properly tested in extension_test.go where the actual resolution logic lives.

the fact that this is different from ES above tells me the config structure is still different. Can we make them identical? The Prometheus change was merged but not released yet, so we have an opportunity for making a consistent config API change.

Prometheus config structure is slightly different from ES/OpenSearch since it wraps promcfg.Configuration with ,squash, but the Authentication field itself is now identical across all backends.
