Month: 2025-06 — In teutonet-helm-charts, delivered Direct Solr admin username configuration for the CKAN Helm chart. The admin username is now configured in values.yaml (default 'admin') and removed from the Kubernetes secret, simplifying authentication setup and aligning the chart with service metrics readiness. Related commit: bd10b9c139a534a422e84ba2f7b0cb94a53178f7 (chore(ckan): change sorl auth in preparation for service metrics). No major bugs fixed this month. Impact: reduces secret management complexity, improves deployment consistency, and accelerates metrics-enabled rollouts. Technologies/skills demonstrated: Helm chart customization, Kubernetes secret handling, YAML configuration, and observability readiness.
