Cause (Documented platform behavior): PSA applies warn/audit to workload resources but enforce only to the resulting Pod objects, so the workload is accepted while the controller's Pod creations are rejected. Fix status: documented_behavior Misleading approaches: - Debugging image pulls/scheduling: no Pod object is ever created Other error fragments: - would violate PodSecurity Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/kubernetes/website/main/content/en/docs/concepts/security/pod-security-admission.md (official_docs, unknown, documented_behavior): Enforce rejects pods; audit/warn apply to workload resources, but enforce is not applied to workload resources, only to resulting pods; exemptions by username/runtimeclass/namespace. - https://raw.githubusercontent.com/kubernetes/kubernetes/master/staging/src/k8s.io/pod-security-admission/admission/admission.go (official_docs, unknown, documented_behavior): Admission messages: 'violates PodSecurity %q: %s' (enforce) and 'would violate PodSecurity %q: %s' (warn). - https://raw.githubusercontent.com/kubernetes/website/main/content/en/docs/concepts/security/pod-security-standards.md (official_docs, unknown, documented_behavior): Restricted profile controls include allowPrivilegeEscalation, runAsNonRoot, seccomp RuntimeDefault and capabilities restrictions. Search phrasings: deployment no pods created violates PodSecurity; kubernetes FailedCreate violates PodSecurity restricted; would violate PodSecurity warning deployment Evidence basis (self-declared by the contributing chat client): public_source.

Problem details

Observed symptom
kubectl apply succeeds (possibly printing 'Warning: would violate PodSecurity ...'), Deployment shows 0/N ready, no Pods exist; ReplicaSet events show FailedCreate with 'violates PodSecurity "restricted:latest": ...'.
Context
Product: Kubernetes Component: Pod Security Admission (built-in) Operation: kubectl apply of Deployment/StatefulSet/Job into a namespace labeled pod-security.kubernetes.io/enforce=restricted|baseline Affected versions: unknown Environment: Kubernetes clusters with PSA namespace labels (managed clusters often label namespaces by default) Trigger: Pod template lacks restricted-profile fields (runAsNonRoot, allowPrivilegeEscalation=false, capabilities drop ALL, seccompProfile RuntimeDefault) or uses hostPath/privileged etc.

Recommended action: Inspect ReplicaSet/Job events for the violation list and add the required securityContext settings; or, if appropriate, adjust the namespace's enforce level/version label or configure exemptions. Option: Make the pod template compliant [evidence: official_recommended_action] Applies when: Namespaces enforcing restricted Steps: 1. kubectl describe rs/<rs> to read the violated fields 2. Set securityContext: runAsNonRoot: true, allowPrivilegeEscalation: false, capabilities.drop: ["ALL"], seccompProfile.type: RuntimeDefault 3. Re-apply and watch pods Expected: Pods are created Evidence basis (self-declared by the contributing chat client): untested.
