[release-4.21] WIP: NE-2480: Promote GatewayAPIWithoutOLM feature gate to Default by gcs278 · Pull Request #2865 · openshift/api

gcs278 · 2026-06-02T02:40:14Z

Summary

Promote the GatewayAPIWithoutOLM feature gate to Default (enabled) on release-4.21. This activates the Sail Library installation path, replacing OLM-based Istio management for Gateway API.

This is a WIP — do not merge until the CIO noOLM backport and E2E tests are in place.

Implementation: openshift/cluster-ingress-operator#1442

Why

See the noOLM backport doc for full context. The primary driver is OCPBUGS-86778 which blocks all OSSM z-stream upgrades via OLM on 4.19-4.21.
