May 1, 2025May 2025 monthly wrap-up for teutonet-helm-charts focused on reliability, security, and release discipline across the Helm chart base. Key features delivered include Traefik integration as the default ingress with compliance upgrades (license and trusted registry handling), Grafana configuration refinements (removing deprecated plugins and enabling datasource loading from both ConfigMaps and Secrets), and enhancements to resource/policy standards (configurable control-plane resources and a unified image pull policy template). Major maintenance and quality improvements include descheduler/base-cluster dependency pinning and version logic refinements for Kubernetes minor versions, RBAC naming consistency to prevent collisions, and an adaptive NetworkPolicy helper for kube-apiserver capabilities. CI process improvements tightened workflow robustness with null-checks and support for multiple artifacthub-values files during releases. Business value: these changes reduce deployment risk, improve security/compliance, standardize runtimes, and accelerate reliable, repeatable releases across environments. Technologies/skills demonstrated: Kubernetes, Helm, Traefik, Grafana, RBAC, NetworkPolicy, resource and pullPolicy templating, descheduler/configuration, base-cluster dependency management, and CI/CD hardening.

Feb 1, 2025February 2025 (teutonet/teutonet-helm-charts) delivered substantial CI automation and reliability improvements, targeted security posture enhancements for T8s clusters, and foundational telemetry work, while strengthening CI governance and release discipline. Key features delivered include automated release-please config management, CI job filtering, and enforcement of README updates for major changes, plus PR title checks for breaking changes; Telemetry configuration was abstracted to enable typed usage; Node-type security rules were implemented for T8s clusters; OIDC support was added to the T8s cluster API server. Major CI bug fixes included pushing only after the last commit and deduplicating CVE results, as well as fixes to PR title validation, missing GH_TOKEN and environment variables, and API usage in CI workflows. These efforts reduced release risk, improved security and observability, and laid groundwork for safer, scalable deployments across Teuto environments.
