Worked on PeerDB-io/peerdb to deliver a configurable TLS Server Name Indication (SNI) feature for the Temporal gRPC client, addressing handshake failures in deployment scenarios such as Temporal Cloud via PrivateLink. The solution introduced the TEMPORAL_TLS_SERVER_NAME environment variable, allowing explicit control over the SNI used during TLS handshakes. This was implemented in Go by refactoring the TLS configuration setup to apply the ServerName when the environment variable is set, while preserving default behavior otherwise. The work focused on backend development, TLS configuration, and environment variable management, improving deployment reliability and enabling future enterprise deployment enhancements without altering existing workflows.

Apr 1, 2026April 2026 monthly summary for PeerDB-io/peerdb: Focused on delivering a robust, configurable TLS SNI control for the Temporal gRPC client to address SNI-related handshake failures in deployment scenarios such as Temporal Cloud via PrivateLink. Introduced the TEMPORAL_TLS_SERVER_NAME environment variable to override the TLS ServerName used during the handshake, enabling correct hostname verification when the dial address differs from the server certificate. Implemented through a refactor that constructs tls.Config up front in setupTemporalClient and applies ServerName when the env var is non-empty, preserving default behavior when unset. The changes are tracked in flow/internal/config.go (PeerDBTemporalTLSServerName) and flow/cmd/cert.go, with the commit 905df3665f09e3c70b168a6ae2bad531a40c7e7e and PR #4215 context. This work reduces handshake-related failures, improves deployment interoperability, and sets the stage for enterprise deployment extensions (e.g., Helm chart exposure).
