GA4GH ServiceInfo Sidecar

The GA4GH Service Info API is a required component across standards such as TES, WES, and TRS, providing essential metadata about a service. Currently, each implementation must manually develop and maintain its own /service-info endpoint, leading to duplication, inconsistent metadata, and difficulty in supporting new capabilities such as security and extensibility features. This project proposes a reusable GA4GH ServiceInfo Sidecar a lightweight proxy service that runs alongside existing GA4GH services and handles /service-info requests centrally, while forwarding all other requests transparently to the backend. The sidecar will generate standard-compliant responses using a combination of static configuration (config.yaml) and dynamic metadata collected through a plugin system, enabling seamless support for service-specific and custom extensions without modifying backend code. The project will deliver a production-ready implementation with schema validation, extensibility aligned with GA4GH specifications, and deployment support via Docker and Kubernetes. Additionally, the sidecar will support Trusted Execution Environments (TEE) by advertising attestation capabilities via the ServiceInfo API and delivering attestation reports through a dedicated endpoint, enabling verifiable trust without implementing low-level attestation logic.
