- Around line 112-114: The konnectivity server test is only checking
kasPodList.Items[0], so an HA control plane can hide stale kube-apiserver pods.
Update the affected assertions in konnectivity_server_test.go to iterate over
all kube-apiserver pods returned by the list, or use a deterministic selector
only after confirming the full replica set is updated. Apply this to the
repeated kasPodList.Items[0] checks in the relevant test blocks so each pod’s
phase, args, and TLS behavior are validated consistently.
- Around line 278-285: The polling block in Eventually for kube-apiserver pod
discovery should not return early on mgmtClient.List errors, because that makes
the poll succeed without validating anything. In the konnectivity_server_test.go
checks that use mgmtClient.List with kasPodList and MatchingLabels{"app":
"kube-apiserver"}, replace the silent return with a failed Gomega expectation or
explicit failure so the Eventually retry fails loudly. Apply the same fix in
both affected polling sections so listing failures cannot be masked.
- Around line 349-352: The readiness checks over kasPod.Status.ContainerStatuses
can pass vacuously when the slice is empty, so add an explicit non-empty
assertion before the per-container loop in the konnectivity server test. Update
both ContainerStatuses iterations in this test to first verify the list has at
least one entry, then keep the existing container-by-container Ready assertions.
Use the existing kasPod.Status.ContainerStatuses and containerStatus.Ready
checks as the place to apply the fix.
- Around line 77-90: The cleanup for the HostedCluster state only restores the
TLSSecurityProfile, so it can leave empty Spec.Configuration or APIServer
structs behind when they were originally nil. In konnectivity_server_test.go,
update the BeforeAll capture logic around the
hostedCluster.Spec.Configuration.APIServer.TLSSecurityProfile snapshot to also
record whether Spec.Configuration and APIServer existed before mutation. Then
restore the exact original shape in the cleanup path using those captured flags,
not just the TLS profile.

Avoid validating only the first kube-apiserver pod.
The test repeatedly uses kasPodList.Items[0], so an HA control plane can pass while another kube-apiserver pod still has stale konnectivity args or TLS behavior. Iterate all listed pods, or select deterministically only after proving the intended replica set is fully updated.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Do not silently pass Eventually when pod listing fails.
In Eventually(func(g Gomega)), returning without a failed expectation makes that poll successful. These branches can let propagation checks pass without ever listing kube-apiserver pods.
Suggested fix
- if err != nil {
- return
- }
+ g.Expect(err).NotTo(HaveOccurred(), "failed to list kube-apiserver pods")As per path instructions, framework paths should fail loudly rather than silently swallow errors.

If ContainerStatuses is empty, these readiness loops pass vacuously. Add a non-empty assertion before iterating.

🌐 Web query:
apiserver-network-proxy proxy-server container image Dockerfile openssl shell
💡 Result:
The apiserver-network-proxy (often referred to as Konnectivity) project utilizes multi-stage Dockerfiles located in the artifacts/images/ directory to build its container images [1][2]. For the proxy-server component, the build process uses a Dockerfile (e.g., artifacts/images/server-build.Dockerfile) that defines two primary stages [2][3]: 1. Builder Stage: Uses a Go toolchain image to compile the proxy-server source code into a static binary. It specifically uses CGO_ENABLED=0 to ensure a statically linked binary [1][3]. 2. Final Stage: Copies the compiled binary into a minimal distroless base image, specifically gcr.io/distroless/static-debian12:nonroot [1][2]. Because the final image is based on a distroless static image, it does not contain a shell (like /bin/sh or /bin/bash) or standard utilities like OpenSSL [1][2]. This design is intentional to minimize the attack surface and image size [1]. If shell access or OpenSSL is required for debugging or troubleshooting, it is recommended to use ephemeral debug containers (e.g., kubectl debug) that include these tools, rather than modifying the production container image [1]. The official build process is automated via a Makefile, which can be triggered using the make docker-build command [4][1][5]. This process supports multi-architecture builds via buildx and allows users to configure build parameters such as registry, image tags, and base images through environment variables [1][5][2].

Run the TLS probe from a tool-enabled container.
The apiserver-network-proxy image is distroless and does not provide the sh or openssl commands used by runOpenSSLClient. Configure this component to exec into control-plane-pki-operator and dial the kube-apiserver pod IP on port 8090, as the webhook probe does.
