WalkthroughThe console plugin now derives nginx TLS protocols and ciphers from the cluster APIServer TLS profile. The controller passes this profile during manifest application. The ConfigMap applies the generated TLS directives. ChangesConsole plugin TLS configuration
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The change dynamically applies the cluster TLS policy to the console plugin and is mergeable with owner awareness; API read errors should be sanitized before logging to avoid exposing internal API hostnames.

convert supported IANA TLS 1.2 names, including
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, into nginx/OpenSSL syntax before
filtering. Filter only TLS 1.3 suites, preserve converted custom TLS 1.2 suites,
and use the Intermediate fallback only when no supported non-TLS-1.3 cipher
remains.

- Line 196: Update ensureConsolePlugin so it checks ShouldHonorClusterTLSProfile
before calling resolveTLSProfileSpec; apply the cluster
APIServer.Spec.TLSSecurityProfile only when honoring is enabled, otherwise
retain the component default for NGINX TLS settings.

Read the cluster's APIServer TLS security profile and render the nginx ssl_protocols and ssl_ciphers directives dynamically. This ensures the console plugin respects cluster-wide TLS policy (Old/Intermediate/ Modern/Custom) and any admin overrides. Falls back to the Intermediate profile when the APIServer resource cannot be read. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
