## TL;DR

Ephemeral containers and kubectl debug evidence help agents investigate minimal or crashing Kubernetes workloads without rebuilding the production image first.

## Core Explanation

Production containers often omit shells, package managers, and network tools. Agents that only ask for application logs may miss namespace, DNS, filesystem, or node-level evidence. Kubernetes debugging workflows provide ways to add a temporary debug container, copy a Pod with modified images, or inspect a node.

The safe path is evidence-first. Agents should record the target Pod, namespace, debug image, profile, RBAC principal, node, cleanup plan, and exact commands before recommending a debug session. A debug container can change the security posture of a live workload, so the recommendation should name the diagnostic purpose and least-privilege profile.
