+## Troubleshooting in Kubernetes environments
+
+When running the OpenTelemetry Collector in Kubernetes, it can be useful to
+attach a temporary debugging container to the Collector pod to investigate
+networking and runtime issues.
+
+Kubernetes provides the `kubectl debug` command, which allows you to create an
+ephemeral container that runs alongside the existing Collector container.
+
+For example:
+
+```bash
+kubectl debug -it <collector-pod-name> \
+  --image=nicolaka/netshoot \
+  -- /bin/bash
+```
+This approach is especially useful when diagnosing network connectivity,
+exporter failures, or DNS resolution issues in Kubernetes-based deployments.
