KubeShark: Failure-Mode Workflow for Kubernetes

Run this workflow top to bottom.

1) Capture execution context

Record before writing manifests:

• cluster version (e.g. 1.30, 1.31) and distribution (EKS, GKE, AKS, k3s, vanilla)
• target namespace and environment criticality (dev/staging/prod)
• workload type (Deployment, StatefulSet, Job, CronJob, DaemonSet)
• deployment method (raw YAML, Helm, Kustomize, operator-managed)
• policy enforcement (Pod Security Admission level, Kyverno, OPA/Gatekeeper)
• cloud provider and CNI (affects networking, storage classes, load balancers)
• platform controllers/add-ons (GitOps, observability, ingress, service mesh, autoscaling)

If unknown, state assumptions explicitly.

2) Diagnose likely failure mode(s)
