October 2025

3 Commits • 2 Features

Oct 1, 2025

October 2025: Delivered major enhancements to Mesh identity and trust, modernized CI for newer Kubernetes releases, and strengthened backward compatibility and security posture. This release focused on enabling zero-downtime SpiffeID migrations within MeshService, decoupling MeshTrust from MeshIdentity to support independent CA validation and compatibility with older Mesh resources, and ensuring trust can be established independently of WorkloadIdentity.

Jul 1, 2025

July 2025 Monthly Summary Focused on security-forward feature delivery, API/data-model standardization, observability improvements, and test/tooling stabilization to drive reliability and business value. Cross-repo efforts ensured consistent data definitions, better workload identity guidance, and clearer operational metrics, while maintenance updates kept dependencies secure and compatible with evolving runtimes. Key features delivered: - SPIFFE Compliance Initiative: planning and design for SPIFFE-based workload identity, trust domains, and certificate management; includes documentation and design work (docs MADR: spiffe compliance and SPIFFE design). - DataSource API Design and Common Structures: standardized data sources across Kuma; introduced common DataSource struct and related API changes; refactored selector/status into common API struct. - Envoy Resource Naming and Observability: unified naming for non-system Envoy resources and metrics to reduce cardinality and improve clarity (docs MADR). Major bugs fixed: - Test Stabilization: removed empty golden files to stabilize tests. - Test Coverage and Debian/IPv6 Support for Transparent Proxy: dropped Debian 10, added Debian 13, and improved IPv6 test coverage; added missing test files. - Route Generation: enforce resource type checking to prevent incorrect routing. - MeshRateLimit: added warning logs for HTTP status codes to prevent misconfigurations. Maintenance and cross-repo improvements: - Envoy and Tooling Upgrades: Envoy upgrades and lint/tooling improvements (bump in Envoy and golangci-lint). - Documentation Clarifications: Kuma website note clarifying MeshTrafficPermission limitation for MeshExternalService (2.9+). - Kuma Mesh Performance: upgrades in mesh-perf to align Kuma and dependencies. Overall impact and accomplishments: - Strengthened security posture with SPIFFE-based identity groundwork and improved trust boundaries. - Achieved better data consistency and cross-repo collaboration through common DataSource patterns. - Reduced risk and improved reliability with stabilized tests, clearer routing decisions, and proactive configuration validation. - Kept the codebase healthy and forward-compatible with newer Envoy versions and tooling. Technologies and skills demonstrated: - Security architecture (SPIFFE), API design, and data modeling. - Observability and naming strategies for large-scale systems. - Test engineering, coverage management, and test stabilization techniques. - CI/tooling upgrades, dependency management, and documentation leadership.
