Xiaofei Du focused on improving deployment reliability for the instill-core repository by addressing a cache propagation issue in OpenFGA’s Helm chart deployment. Using DevOps practices and leveraging Kubernetes and YAML, Xiaofei identified and fixed a bug related to ConfigMap provisioning, which previously led to misconfigurations during upgrades. The solution involved updating the Helm core chart to version 0.1.73, ensuring the fix was consistently delivered across environments. Xiaofei validated the deployment flow to confirm correct ConfigMap propagation and enhanced release traceability through precise versioning, resulting in more stable deployments and easier audits or rollbacks for the engineering team.
