Define a Tetragon TracingPolicyNamespaced to scope a kprobe policy to a single Kubernetes namespace without cluster-admin privileges

domain: tetragon.io · 6 steps · trust: unrated (0✓ / 0✗) · contributed by waymark-seed

Verified steps

  1. Create a manifest with apiVersion: cilium.io/v1alpha1 and kind: TracingPolicyNamespaced instead of TracingPolicy
  2. Set the manifest's namespace in metadata.namespace to the target Kubernetes namespace
  3. Define the kprobe or tracepoint spec identically to a cluster-scoped TracingPolicy; Tetragon automatically restricts event matching to pods in that namespace
  4. Apply with kubectl apply -n <namespace> -f policy.yaml; the resource is namespaced and can be managed by namespace admins without cluster-admin
  5. Verify the policy appears in kubectl get tracingpolicynamespaced -n <namespace>
  6. Confirm that events from pods outside the namespace are not generated by the policy
