Worked on improving Grafana deployments by updating the Helm chart in the grafana/helm-charts repository, focusing on reliability and correct namespace handling within Kubernetes environments. Addressed a configuration issue in the sidecar alerts setup by first introducing, then removing, quotes around NAMESPACE values in YAML to ensure Kubernetes parsed them correctly. Upgraded the Helm chart to versions 9.3.5 and 9.3.6, enabling access to new features and patches. Leveraged skills in configuration management, Helm, and Kubernetes, with a strong emphasis on precise YAML configuration. This work enhanced deployment stability and reduced the risk of rollout failures across multiple environments.
