(Commits: api: Disallow "openshift-v" prefix on version IDs; api: Disallow X.Y.Z cluster versions) - E2E tests: Updated end-to-end tests to stop expecting an OpenShift version prefix, aligning tests with API validation and improving test reliability. (Commit: e2e: Remove "openshift-v" version prefix) - Config updates: Bumped Red Hat RP images and upgraded frontend/backend image digests to latest builds, ensuring consistency with validated deployments. (Commits: config: Bump RP images; config: Bump frontend and backend image digests) - Frontend/Audit maintenance: Removed an unused frontend constant and refactored NewOtelAuditClient for better maintainability. (Commits: frontend: Remove unused constant contextKeyAuditLogger; audit: Refactor NewOtelAuditClient) - Demo and E2E hardening: Fixed cluster version, corrected az keyvault key show command in demo, and removed PATCH values from cluster versions in demo/test; updated e2e bicep modules and de-linted modules for reliability. (Commits: demo: Fix cluster version; demo: Fix "az keyvault key show" command; demo: Remove PATCH value from cluster versions; e2e: Update bicep modules for customer-managed etcd encryption; e2e: De-lint bicep modules) - External authentication improvements: Enforced issuer URL presence and expanded handling for external auth deletions and CA clearing, improving security and user experience. (Commits: api: External auth token issuer URL will always be present; backend: Handle external auth deletions; api: Allow clearing TokenIssuerProfile.Ca) - Additional API/OCM work: Included improvements around ExternalAuth in frontend/OCM, and ongoing refactoring to improve clarity and consistency across APIs. (Commits: frontend: Properly convert ExternalAuthClientType to/from CS; ocm: Add ListExternalAuths; ocm: Rename helper functions) Major bugs fixed: - Demo: Fixed az keyvault key show command and general cluster version issue in the demo suite. - Remove PATCH value from cluster versions in demo and test to avoid stale version data. - API: Do not use 'omitempty' before enum validation to ensure proper enum handling. - ARM: Remove validation tags from SystemData to simplify validation logic. - CLI: Always specify output format for az output to improve consistency. - OCM: Fix ListIterator bugs and other minor stability improvements. Overall impact and accomplishments: - Strengthened platform reliability, security, and maintainability through API validation hardening, test hygiene improvements, and up-to-date image pipelines. - Reduced risk from versioning and configuration drift by aligning API validation with E2E tests and CI pipelines, and by updating image digests across frontend/backend and RP images. - Enhanced external authentication security and manageability, including issuer URL enforcement and deletion/CA handling, supporting more robust identity management for customers. Technologies/skills demonstrated: - Go-based API validation, input sanitization, and enum handling; end-to-end test alignment; Bicep/IaC updates and linting; image digest management; frontend/backend interoperability; and cross-repo coordination for security and reliability.
