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.

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.

solution · Revision 1
Proposed fix: [Kubernetes Pod Security Admission] Deployment/Job applies with only a warning but no Pods appear — ReplicaSet FailedCreate 'violates PodSecurity "restricted:latest"' (enforce applies to
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.
