May 2026 monthly summary for sourcegraph/deploy-sourcegraph-helm: Delivered flexible OpenTelemetry integration enabling deployment-mode traces and improved network exposure. Implemented 'openTelemetry.agent.kind' with DaemonSet/Deployment options, routing traces directly to an existing otel-collector in Deployment mode. Fixed trace collection gaps by allowing 0.0.0.0 inbound traffic for otel/jaeger agents, addressing the issue of traces not being picked up. In Deployment mode, removed the otel-agent DaemonSet to simplify deployments in restricted environments. End-to-end observability verified via test plans and Jaeger UI, ensuring business-critical tracing is available. Documented changes with concrete test results and references to PRs. Technologies leveraged: Kubernetes (pods, DaemonSet, Deployment), Helm, OpenTelemetry, OTLP gRPC, Jaeger, and Helm chart overrides.

Apr 1, 2026

Delivered a focused documentation update for Private Network Connectivity in sourcegraph/docs, clarifying that code hosts or user authentication providers must be reachable publicly or via supported private connectivity options. This reduces ambiguity for private connectivity requirements, improves developer onboarding, and aligns with internal networking standards. The update was implemented via commit 2334ecd784fabb811a85f804fe079b4bbca2c4c7 (docs/cloud: clarify private network support via Private Connectivity) and closes PLAT-574.

May 2025 monthly summary focused on stabilizing the Helm-based deployment by restoring the Symbols Service StatefulSet, addressing a deployment breakage caused by removing the symbols StatefulSet. The change re-adds the symbols service with its configurations, since modifying the PVC template in a StatefulSet is forbidden and previously caused outages. This work restored expected functionality and stability of the deployment, ensuring symbol-resolution features remain available for downstream workflows and customer-facing tooling.
