July 2025: Delivered a comprehensive OIDC trusted CA configuration and lifecycle across all distribution deployments, enabling secure use of self-signed and custom CAs for OIDC token validation. Centralized CA management via a single oidc-trusted-ca secret, added oidcTrustedCA field with defaults, and introduced trustedCAPath support during transition, with updates across EKS, KFD distribution, and on-prem deployments. Implemented end-to-end changes in schemas, templates, patches, and kustomization, plus uninstall cleanup and extensive docs/models updates to reflect new configuration and usage. This work improves security posture, reduces operator toil, and broadens compatibility for customers using internal PKI and self-signed certificates.
