July 2025: Delivered dual-stack IP support for services (IPv4/IPv6) across components in bitnami/charts, by adding configurable IP family policies and a list of supported IP families in the Thanos chart and Fluentd service. This enables IPv4/IPv6 compatibility and broader networking flexibility. The work was implemented via two commits across components: ee5ebddd317f9b1bb39f4b6c3da9297713b2b156 and a85496ed73f248785575019bfef78af8552e5f9d (PRs #34825, #34827). Major bugs fixed: none reported this month. Impact: enables IPv6-ready deployments in Kubernetes environments, reduces manual networking tweaks, and accelerates dual-stack adoption for customers. Technologies/skills demonstrated: Kubernetes Helm charts, dual-stack networking, IP family policy configuration, cross-component configuration, and PR-driven development.
