Gerrit Gudat upgraded the Gardener platform to version 1.117.5 within the sapcc/helm-charts repository, focusing on deployment manifests, Helm charts, and configuration files. He incrementally updated image tags, dependencies, and metadata across Chart.lock, Chart.yaml, README.md, and values.yaml to ensure deployments consistently used the latest stable release. By structuring the upgrade path through sequential commits, Gerrit provided clear traceability and minimized risk during the transition. His work leveraged Kubernetes and Helm, using YAML for configuration management, and improved deployment stability and security by aligning the platform with the latest Gardener features and best practices for reproducible infrastructure deployments.
