Address OCP mcpchecker harness/fixture false fails so core tasks can clear the 80% gate (need two more taskPassed=true from ~22/29):

  • fix-service-routing: PSS-safe verify probe; nginx-unprivileged targetPort 8080
  • ssa-field-preservation: shell setup/verify (avoid alabama kubeconfig path)
  • evals.mk: export KUBECONFIG from MCP_EVAL_KUBECONFIG; force --cluster-provider kubeconfig; put _output/tools/bin (jq) on PATH
  • statefulset-lifecycle: wait for db-0 Ready before data checks
  • multi-container / create-pod-resources-limits: require restricted PSS in prompts; longer Ready waits (300s)
  • fix-service-with-no-endpoints: longer Ready wait; core maxToolCalls 20→25
  • setup-dev-cluster verify: PSS-safe network-isolation probe pods

📝 Walkthrough

Walkthrough

The PR updates evaluation runtime configuration and Kubernetes task scripts. It adds kubeconfig propagation, restricted Pod Security requirements, pinned probe images, longer readiness waits, a scripted SSA lifecycle, and more explicit StatefulSet and service verification.

Changes

Evaluation reliability

Layer / File(s) Summary
Evaluation runtime configuration
build/evals.mk, evals/core-eval-testing/builtin-openai/eval-core.yaml
Evaluation commands now propagate kubeconfig settings, include required tool directories in PATH, select the kubeconfig cluster provider, and allow up to 25 tool calls.
Restricted Kubernetes task execution
evals/tasks/core/create-pod-resources-limits/*, evals/tasks/core/fix-service-routing/*, evals/tasks/core/fix-service-with-no-endpoints/verify.sh, evals/tasks/core/multi-container-pod-communication/*, evals/tasks/core/setup-dev-cluster/verify.sh
Task prompts and verification pods now use restricted Pod Security settings. Service routing uses port 8080 and a pinned curl image. Verification scripts add stricter failure handling and longer readiness waits.
Server-side apply task lifecycle
evals/tasks/core/ssa-field-preservation/*
The SSA task now references external setup, verification, and cleanup scripts. The scripts recreate the namespace, apply the deployment, wait for availability, validate annotations and resources, and clean up the namespace.
StatefulSet lifecycle verification
evals/tasks/core/statefulset-lifecycle/verify.sh
The verifier checks deletion of each secondary pod, waits for the primary pod to become ready, reports diagnostics on timeout, and exits explicitly on success.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to e6053

The PR changes CI evaluation scripts and task guidance, but the current changes can report successful verification after API or deletion failures, fail on transient endpoint convergence, or reject valid OpenShift configurations. These concrete correctness issues make the PR not merge-ready until addressed.

Kubernetes Pod Security Standards restricted allowPrivilegeEscalation capabilities drop ALL runAsNonRoot seccompProfile pod container scope

💡 Result:

The Kubernetes Restricted Pod Security Standard (PSS) is designed to enforce pod hardening best practices [1][2]. To comply with the Restricted profile, your Pod configuration must meet specific requirements across both Pod-level and Container-level security contexts [1][3]. Key requirements for the Restricted profile include: 1. Privilege Escalation: Must be disallowed [1][2]. You must set spec.containers[].securityContext.allowPrivilegeEscalation to false [1][4]. 2. Capabilities: Must drop all capabilities [2][3]. You must set spec.containers[].securityContext.capabilities.drop to include ALL [2][4]. 3. Running as Non-Root: The container must be required to run as a non-root user [1][2]. You must set spec.securityContext.runAsNonRoot (or at the container level) to true [1][5]. 4. Seccomp Profile: Must be explicitly set to RuntimeDefault or Localhost [1][2]. You must set spec.securityContext.seccompProfile.type (or at the container level) to RuntimeDefault or Localhost [1][6]. Regarding scope, these settings can be applied at either the Pod level (spec.securityContext) or the Container level (spec.containers[*].securityContext), with the following nuances: - Overrides: Container-level settings override Pod-level settings [5]. If a field is defined in both, the container-specific configuration takes precedence [5]. - Inheritance: Many fields (such as runAsNonRoot and seccompProfile) can be set at the Pod level to apply as a default for all containers within the Pod [1][5]. However, fields like allowPrivilegeEscalation and capabilities are typically defined at the container level [6][5][3]. - Flexibility: The Restricted policy allows the Pod-level field to be undefined if all individual container-level fields are set, and vice versa (for fields that support both) [1][7]. Example configuration for a compliant Pod: apiVersion: v1 kind: Pod metadata: name: restricted-compliant-pod spec: securityContext: runAsNonRoot: true seccompProfile: type: RuntimeDefault containers: - name: main-container image: my-app:latest securityContext: allowPrivilegeEscalation: false capabilities: drop: ["ALL"]

Citations:


Clarify the scope of each security field.

allowPrivilegeEscalation and capabilities.drop are container-level fields. Specify pod-level runAsNonRoot=true and seccompProfile.type=RuntimeDefault, then require allowPrivilegeEscalation=false and capabilities.drop=["ALL"] in each container securityContext. Otherwise, an agent can place container-only fields under spec.securityContext, which can cause Restricted admission to reject the pod.

Kubernetes official documentation Service selector EndpointSlice controller asynchronous endpoint propagation

💡 Result:

In Kubernetes, the EndpointSlice controller manages the relationship between Services and their backend endpoints. When a Service defines a selector, the EndpointSlice controller continuously monitors for Pods matching that selector and automatically creates and maintains the corresponding EndpointSlice objects [1][2][3]. The propagation of endpoint changes is an asynchronous process driven by the Kubernetes control plane's reconciliation loop [1][2][4]. Key aspects of this mechanism include: 1. Asynchronous Reconciliation: The EndpointSlice controller operates by watching for changes to Pods, Services, and existing EndpointSlices [5][6]. When a relevant change occurs (such as a Pod being created, deleted, or changing its ready state), the controller queues a sync request for the associated Service [5]. This process is inherently asynchronous, meaning there may be a brief delay between a state change in the cluster (like a Pod becoming ready) and the update being reflected in the EndpointSlice objects [4][7]. 2. Service Selector Logic: The controller uses the Service's selector to identify the desired set of Pods [1][3]. It iterates through all matching Pods and groups them into EndpointSlices based on shared attributes such as IP family, protocol, and port number [2][8][4]. 3. Scalability and Thresholds: To prevent creating excessively large objects, the controller automatically partitions endpoints into multiple EndpointSlice objects [2][3]. By default, a new EndpointSlice is created once an existing slice exceeds 100 endpoints, helping to maintain efficient propagation and performance [3]. 4. Consistency and Mirroring: EndpointSlices act as the source of truth for kube-proxy [2]. Because the process is asynchronous, transient inconsistencies can occur under heavy load or rapid churn, leading to scenarios where the API server might experience delays in reflecting the latest state [4][7]. To ensure reliability, the system uses label mirroring, where the controller ensures that critical metadata (such as Service labels) is propagated to the EndpointSlices, maintaining consistent identification across the cluster [2][8][9]. In summary, while the EndpointSlice controller strives to maintain an up-to-date view of service backends, the propagation is not instantaneous; it relies on the controller-runtime's queueing and reconciliation mechanisms to eventually converge on the desired state defined by the Service selector [5][4].

Citations:


Wait for endpoint convergence before failing.

When the Service selector fix has not propagated, kubectl get endpoints nginx -n web -o jsonpath='{.subsets[0].addresses}' can return an empty value. The [[ -z "$endpoints" ]] branch then exits before the connection probe. Poll for a bounded period before returning the no-endpoints error.

OpenShift restricted SCC runAsUser namespace allocated UID range official documentation nginx-unprivileged image UID arbitrary user official

💡 Result:

In OpenShift, containers are automatically managed by Security Context Constraints (SCCs), typically the restricted-v2 SCC by default [1][2]. This SCC forces pods to run using a UID allocated to the namespace [1][3]. 1. Namespace UID Allocation: Upon creation, every OpenShift project (namespace) is assigned a unique UID range [4][5][6]. You can find this range by inspecting the namespace annotations: oc describe project <project_name> Look for the openshift.io/sa.scc.uid-range annotation (e.g., 1000620000/10000) [7][6]. 2. UID Enforcement: The restricted-v2 SCC uses a MustRunAsRange strategy [1][8]. If a pod does not specify a UID, it defaults to the first UID in the namespace's allocated range [1][4][6]. Any attempt to run a container with a UID outside this assigned range will be rejected unless the service account is granted a more permissive SCC (like anyuid), which is generally discouraged for security reasons [4][6]. 3. NGINX-Unprivileged Image: The official nginxinc/nginx-unprivileged image is designed to run as a non-root user (by default, UID 101) [9][10][11]. However, because OpenShift overrides this with the namespace-allocated UID, the container will run as the allocated UID instead of 101 [4][6]. - Permission Handling: Since the container will run with a random UID from the range but will generally belong to GID 0 (the root group), you should ensure your application files are group-readable and writable by GID 0 [12][4][6]. - Recommended Practice: Instead of hardcoding UIDs or requesting specific ranges, configure your Dockerfile to allow the application to function regardless of the UID by setting permissions appropriately [12][6]: RUN chgrp -R 0 /path/to/app && chmod -R g=u /path/to/app This approach ensures compatibility with OpenShift's security model without requiring privileged access or custom SCCs [4][6].

Citations:


Do not recommend runAsUser: 1000 for OpenShift

When the target uses the OpenShift restricted SCC, UID 1000 may fall outside the namespace’s allocated UID range and cause admission rejection. Instruct users to omit runAsUser or select a UID allowed by the namespace. Ensure the images and shared volume support the assigned UID.

Fail closed when deletion cannot be verified.

Both deletion checks can treat API, authentication, or transport errors as “not found,” allowing a stale resource to satisfy later verification. Use --ignore-not-found -o name and accept only an empty successful result in the StatefulSet check; in the service-routing check, do not suppress probe-Pod deletion errors with || true before applying and waiting on the probe.
