April 2026: Delivered the Dynamic hostnames annotation for GSLB (k8gb.io/exposed-hostnames), enabling dynamic resolution of hostnames to IPs for GSLB resources and eliminating the need for hardcoded IPs in NATed environments. Implemented as a feature with API group integration, validation, and comprehensive documentation, aligned with the migration in #2203 and related changes. Enhanced reliability and observability by making empty DNS answers fail-closed and by emitting ExposedIPResolutionError events for visibility into hostname resolution failures. Expanded test coverage and docs: regression tests for no-answer DNS scenarios, Terratest startup DNS retry, and updated docs with docs/exposed-hostnames.md and mkdocs navigation. Business impact includes reduced operational overhead from manual IP management, improved routing flexibility in dynamic/cloud/on-prem environments, and stronger uptime guarantees for global traffic. Technologies/skills demonstrated include Kubernetes CRD annotations, dynamic DNS resolution, error handling and observability, Go-based testing (Terratest), documentation, and API policy migrations.
