Worked on the openfga/helm-charts repository to implement preshared keys authentication using Kubernetes secrets, replacing previously hardcoded credentials in deployment configurations. Leveraging Helm and YAML, the solution enables secure retrieval of authentication keys from Kubernetes secrets, allowing users to specify the secret name directly in deployment settings. The update also standardized environment variable naming to OPENFGA_AUTHN_PRESHARED_KEYS for consistency across components. Comprehensive testing was added to validate secret creation, environment variable mounting, and integration with the authentication module. This work improved security, deployment consistency, and maintainability for OpenFGA deployments, demonstrating a strong focus on configuration management and DevOps best practices.
