… v0.36.2
Bumps sigs.k8s.io/controller-runtime v0.21.0 -> v0.24.1 and
k8s.io/{api,apiextensions-apiserver,apimachinery,client-go,kubectl}
v0.33.9 -> v0.36.2, plus transitive dependency updates picked up by
go get + go mod tidy.
This is a prerequisite for adopting github.com/openshift/controller-runtime-common/pkg/tls
(requires controller-runtime >= v0.22.5) to fix TLS 1.3 adherence in a
follow-up commit. Sent upstream as its own PR (operator-framework/ansible-operator-plugins)
since it is a routine, generic dependency bump unrelated to any OpenShift-specific
feature; once/if it merges upstream, this carry commit becomes a no-op on the
next "Merge upstream tag" rebase.
Two real, CI-only fixes are required by this bump (both silently masked in a
local sandbox that lacks a working golangci-lint/go toolchain pairing and the
envtest etcd binary, but reproduced deterministically in real Prow/GitHub
Actions `sanity`/`unit` runs):
- internal/ansible/proxy/requestfactory/requestinfo.go: k8s.io/apimachinery
v0.36.2 deprecated path.IsValidPathSegmentName in favor of
k8s.io/apimachinery/pkg/api/validate/content.IsPathSegmentName (same
signature); switch the one call site to the new package to keep
`golangci-lint`'s staticcheck (SA1019) happy.
- internal/ansible/handler/logging_enqueue_object_test.go: controller-runtime
v0.24.1 added pkg/webhook/conversion/metrics/metrics.go, which
unconditionally self-registers a new controller_runtime_conversion_webhook_panics_total
counter on the shared metrics.Registry. filterGauges only excluded
rest_client_requests_total, so the extra family broke the HaveLen(1)/BeEmpty
assertions in 4 specs; switch it to an allow-list on the
resource_created_at_seconds family the suite actually exercises, which is
robust to controller-runtime registering further default metrics in future.
Pre-existing test/ansible/proxy and test/e2e/ansible failures that need a live
cluster/kubeconfig are unrelated and fail identically on main without this
change.
This repo does not vendor upstream, so vendor/ sync for this bump is a
separate commit (upstream carries no vendor/ tree at all).

Exercise clusterTLSPolicy.Apply in this test.
This test never calls Apply. It manually creates the TLS callback and appends it to an empty options.Metrics.TLSOpts slice. A regression in Apply can therefore pass this test, and the test does not verify that existing TLS options are preserved.
Use a fake REST client/server or inject the client factory. Seed options.Metrics.TLSOpts with a sentinel callback, call Apply, and assert that the callback is preserved and the profile callback sets tls.VersionTLS13.

Adds internal/cmd/ansible-operator/run/tlspolicy.go: a ClusterTLSPolicy interface (Apply/Watch) plus RegisterClusterTLSPolicy, and wires it into run/cmd.go: - run() now uses a cancellable context (derived from signals.SetupSignalHandler()) so a registered policy can trigger a graceful shutdown/restart. - If a policy is registered, Apply() is called after f.ToManagerOptions() and before manager.New() so it can augment manager.Options (e.g. metrics server TLSOpts). - If a policy is registered, Watch() is called once the manager exists and before mgr.Start(ctx), so it can react to policy changes at runtime. No policy is registered by default (registeredTLSPolicy is nil), so this is a no-op, backward-compatible change with zero new dependencies. Sent upstream as its own PR (operator-framework/ansible-operator-plugins) as a generic extension point; a follow-up carry commit adds an OpenShift-specific implementation that registers itself via this hook.

…n Ansible operator metrics server Fixes the tls13-adherence CI job: the ansible-operator's metrics server (port 8443) never set a TLS MinVersion, so it always negotiated down to TLS 1.2 regardless of the cluster's configured TLS security profile, violating strict adherence on Modern (TLS-1.3-only) clusters. Adds internal/ansible/openshifttls, a downstream-only package that: - registers itself with the generic run.ClusterTLSPolicy extension point (see previous commit) via a blank import from cmd/ansible-operator/main.go; - fetches the TLS profile from apiservers.config.openshift.io/cluster at startup using github.com/openshift/controller-runtime-common/pkg/tls (FetchAPIServerTLSProfile / NewTLSConfigFromProfile), falling back to the default (Intermediate) profile on any error - e.g. non-OpenShift clusters or a missing APIServer object/CRD - so startup is never blocked; - appends the resulting TLS config (MinVersion/CipherSuites) to options.Metrics.TLSOpts; - registers a SecurityProfileWatcher that cancels the manager's run context when the profile changes, triggering a graceful shutdown; the surrounding Deployment/container restart re-applies the (possibly new) profile on the next boot. Also: - adds a get/list/watch RBAC rule for config.openshift.io/apiservers to the Ansible plugin's role.go scaffold template, and mirrors it (via `make generate`, verified to produce an identical diff) into the memcached-molecule-operator testdata's role.yaml - the fixture this CI job actually deploys; - adds github.com/openshift/controller-runtime-common (and its transitive github.com/openshift/api, github.com/openshift/library-go) to go.mod/go.sum (vendor/ synced in the following commit). This commit is genuinely OpenShift-specific and is not proposed upstream; it is permanent carry, unlike the two preceding commits.

… for CI reuse CI jobs that just need a running sample operator (e.g. the tls13-adherence scanner job) currently reimplement a stripped-down deploy sequence directly in the openshift/release ci-operator config, missing the memory-limit patch and RBAC tweaks this script already applies, and working around the lack of a kubectl binary via a manual oc-to-kubectl symlink. Extract the setup/patch/deploy logic into a deploy_operator() function (mirroring the existing test_operator() function), and add a DEPLOY_ONLY=true mode that calls deploy_operator and then exits before the CR-based functional test and undeploy, leaving the operator running. Expose it via a new deploy-e2e-ansible Makefile target so callers don't need to know the env var. Default (unset) behavior is unchanged.

Summary
Fixes the
tls13-adherenceCI job added in openshift/release#83172: the rehearse run deploystestdata/memcached-molecule-operatoron a cluster configured with the Modern (TLS-1.3-only)APIServerTLS profile, then scans every workload's TLS-enabled endpoints. It fails onmemcached-molecule-operator-system:8443(the controller-runtime metrics server, enabled via--metrics-secure) because it still offers TLS 1.2:The root cause: nothing in this repo ever read the cluster's centralized TLS security profile from
apiservers.config.openshift.io/clusterand applied it to the metrics server'sMinVersion/CipherSuites(OCPSTRAT-2611).This mirrors the already-merged fix for the Helm operator base image in openshift/ocp-release-operator-sdk#460, split the same way into layered commits to minimize future rebase conflicts against upstream

Also adds theconfig.openshift.io/apiserversget,list,watchRBAC rule to the Ansible plugin's scaffold template and mirrors it into thememcached-molecule-operatortestdata fixture that the CI job deploys (verified viamake generateto produce an identical diff).Update vendor directory(downstream-only vendor sync for CFE-1098: Rebase upstream v1.35.0 #4's new deps:openshift/controller-runtime-common,openshift/api,openshift/library-go).add tests for TLS policy extension point and OpenShift TLS profile adherence.Update vendor directory(downstream-only vendor sync fortestify/require, newly used by CFE-1114: UPSTREAM: <carry>: Bump kubernetes.core to v2.4.2 #6's tests).vendor/is touched only in the three commits explicitly marked as such; the four commits mirroring the upstream PRs and the OpenShift-specific feature never touchvendor/, since upstream doesn't carry one.Test plan
