From f2d91beb7aaf3c0c87108ec13a9677ec2ef89ebd Mon Sep 17 00:00:00 2001 From: Ugo Giordano Date: Wed, 17 Jun 2026 23:06:03 +0200 Subject: [PATCH] feat: integrate with cluster TLS security profile Read the cluster TLS profile from apiservers.config.openshift.io/cluster at startup. Apply MinVersion, CipherSuites, and NextProtos to webhook and metrics server TLS configs. Fail closed on unexpected errors. Use Intermediate defaults on non-OpenShift clusters.
