Ghislain Cheng enhanced deployment configurability for the zama-ai/kms repository by adding support for custom pod annotations in the KMS Core Helm Chart. He introduced a podAnnotations section within the StatefulSet template, exposed this configuration through values.yaml, and incremented the chart version to ensure a smooth upgrade path. Using Helm, Kubernetes, and YAML, Ghislain enabled users to attach custom metadata to pods, supporting observability, security tooling, and policy enforcement across environments. The work focused on a single feature, demonstrating depth in Helm chart templating and Kubernetes resource management, and improved release readiness by aligning changes with proper versioning practices.
