Jun 1, 2025June 2025 Monthly Summary for gravitl/netmaker Overview: In 2025-06, delivered a focused set of improvements across DNS reliability, egress policy enforcement, gateway management, graph-driven analytics, and deployment traceability, while hardening security baselines and reliability. These initiatives reduce risk, improve operability, and provide clearer traceability from install to production, delivering tangible business value through more reliable networking, policy governance, and deployment hygiene. Key features delivered: - DNS reliability improvements: corrected default domain value, improved host DNS handling, and ensured DNS settings are consistent across migrations. - Egress policy hardening: fixed validation, resource checks, egress range handling, and tagging to ensure accurate and enforceable policies. - Gateway management enhancements: added ability to switch internet gateways from the gateway page; integrated inet gateways into the gateway set; improved handling of relayed egress ranges during migrations. - Graph API and analytics: introduced Graph API integration and enhanced host location data collection to improve graph rendering and operational insights. - Build/install traceability and security baseline: added install script version tagging and release tag updates; established a default user policy on CE to enforce security baselines. Major bugs fixed: - DNS issues: default domain value, host DNS settings, and DNS-related migration consistency resolved. - Egress reliability: corrected egress validation, resource checks, and labeling issues across egress policies. - Gateway and inet gateway cleanup: fixed inet gateway validation on updates and ensured proper unsetting on gateway deletion; resolved related edge cases. - Misc fixes: removed MAC address check; fixed merge conflicts; addressed duplicate CLI table packages; resolved pro package errors; removed extclients on network destroy; ignore last check-in when timestamp is zero. Overall impact and accomplishments: - Increased DNS reliability and predictable DNS behavior, reducing customer troubleshooting time. - Strengthened network policy enforcement, decreasing misconfigurations and security risk associated with egress rules. - Improved gateway management UX and reliability, enabling faster and safer network changes. - Enhanced observability and data-driven decisions through Graph API and location analytics. - Improved deployment reproducibility and security posture via version-tagged install scripts and baseline CE policies; storage optimization via controlled log retention. Technologies/skills demonstrated: - DNS/configuration management, egress policy engineering, and gateway orchestration. - Graph API integration and telemetry data collection. - Install script tagging and release tagging for reproducible deployments. - Migration handling, security hardening, and code hygiene (merge conflict resolution, removal of redundant packages).
