TL;DR

  • Adds an operator-configured W3C baggage allowlist for invocation-service span attributes.
  • Keeps the public default empty, so deployments opt in to every emitted attribute.

Additional Details

  • Copies only configured baggage keys after W3C parsing; missing keys are ignored.
  • Renders the Helm list as an invocation-service environment setting and restarts Pods when it changes.

For QA

  • cargo test --lib
  • helm lint nvcf-invocation-service
  • Rendered the chart with and without configured allowlist entries.

Issues

Closes #961

Checklist

Github commit:
feat(invocation): configure baggage span attributes

Add an operator-configured allowlist for W3C baggage copied to invocation-service
span attributes. Render it through Helm and keep the default empty.

Summary by CodeRabbit

  • New Features

    • Added configurable propagation of selected W3C baggage entries to request tracing spans.
    • Added deployment settings for specifying an allowlist of baggage keys.
    • Baggage propagation is disabled by default until keys are explicitly configured.
    • Unlisted or missing baggage keys are excluded from span attributes.
  • Bug Fixes

    • Tracing configuration changes now reliably trigger deployment updates.
  • Tests

    • Added coverage for default behavior, configured allowlists, filtering, and deployment updates.

Closes #961

📝 Walkthrough

Walkthrough

The invocation service now supports an optional W3C baggage attribute allowlist. Deployment templates pass the list through environment configuration, and request spans copy only configured baggage keys.

Changes

Invocation tracing baggage

Layer / File(s) Summary
Deployment configuration
deploy/helm/http-invocation/nvcf-invocation-service/values.yaml, deploy/helm/http-invocation/nvcf-invocation-service/templates/configmap-env.yaml, deploy/helm/http-invocation/nvcf-invocation-service/templates/deployment.yaml, deploy/stacks/self-managed/global.yaml.gotmpl
Deployment configuration exposes invocation.tracing.baggageAttributeAllowlist, renders it as a comma-separated environment variable, and includes tracing settings in the deployment checksum.
Tracing settings and environment parsing
src/invocation-plane-services/http-invocation/crates/server/src/telemetry/settings.rs, src/invocation-plane-services/http-invocation/crates/server/src/settings/mod.rs
TracingSettings stores a default-empty allowlist. Environment parsing converts comma-separated values into the configured list. Tests cover defaults and deserialization.
Request span enrichment
src/invocation-plane-services/http-invocation/crates/server/src/app.rs, src/invocation-plane-services/http-invocation/crates/server/src/middleware/spans.rs
NVCFMakeSpan receives the allowlist, preserves the incoming parent context, and copies only matching baggage entries to request span attributes. Tests cover filtering and absent keys.
Self-managed integration validation
deploy/stacks/self-managed/Makefile, deploy/stacks/self-managed/tests/invocation-tracing-baggage.sh
The self-managed test target renders default and configured allowlists and verifies environment output and deployment checksum changes.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 2cbf2

The change adds opt-in baggage span attributes with an empty default and validated Helm configuration behavior; no actionable merge-blocking risk remains after normal checks and review.
