Quentin contributed targeted enhancements to the grafana/helm-charts repository, focusing on improving namespace filtering for the rollout operator’s webhooks. By implementing matchExpressions support in the namespaceSelector and introducing a centralized namespaceSelector in the rollout value file, Quentin enabled more precise and maintainable configuration of webhook deployments. The work was delivered using YAML and leveraged DevOps practices with Helm and Kubernetes, aligning the Helm chart with the latest rollout operator features. Over the course of the month, Quentin prioritized feature delivery and versioning, culminating in a chart version bump that improved deployment precision and streamlined ongoing maintenance without introducing new bugs.
