PROFILE
Omer-vishlitzky
Worked on the openshift/assisted-service repository, delivering features and fixes that enhanced automation, security, and reliability for OpenShift cluster installations. Focused on backend development using Go, YAML, and Docker, the work included agent-based installation improvements, GPU data exposure in agent inventory, and prioritized bootable disk selection to improve deployment outcomes. Security compliance was strengthened through FIPS 140-3 build enablement, Go 1.25 upgrades, and dependency updates addressing CVEs. Additional efforts included secure certificate bundling for ignition endpoints, FIPS usage tracking for auditability, and TLS certificate validation fixes for Day-2 hosts, ensuring robust, compliant, and maintainable infrastructure provisioning workflows.

Mar 1, 2026March 2026: Delivered a focused TLS certificate validation fix for Day-2 hosts by reading the MCS CA cert from the machine-config-server-ca ConfigMap instead of kube-system/root-ca, with a fall-back to the legacy source for pre-4.19 spokes. Updated ignition injection to include the MCS CA, ensuring proper TLS validation when downloading config from port 22623. The change centralizes MCS CA management to the machine-config-operator and preserves Hypershift fallbacks. This improves security, reliability, and upgrade compatibility for Day-2 provisioning across clusters (MGMT-22967).

Feb 1, 2026February 2026 — openshift/assisted-service: Delivered two security/compliance-focused features that improve auditability, CA handling, and Day-2 reliability. Key outcomes include FIPS Usage Tracking in Inventory Management for enhanced compliance monitoring and Secure Certificate Bundling for Day-2 Ignition Endpoints to strengthen CA handling (decode, combine, validate). These changes reduce risk during installation and Day-2 onboarding while increasing visibility for audits and governance. No major bugs were reported in this scope.
