Major bugs fixed: - Fixed syntax for invoking the shared license workflow and ensured proper secret propagation in the CI configuration to restore license header checks. Overall impact and accomplishments: - Greater release reliability, faster iteration cycles, and stronger security posture for CI/CD pipelines. - Improved demYST (demo environment) consistency and reduced risk in testing and demos. - Enhanced maintainability through centralized configuration handling and safer Helm chart practices. Technologies/skills demonstrated: - Kubernetes CRD regeneration and Helm-based deployments, secret handling in Helm values, and ReleaseNamespace usage. - GitHub Actions workflow security (GitHub App tokens) and backport automation. - kubeconfig management and versioning for Kubernetes access in charts and plugin definitions.
