# CoreWeave Debug Bundle

## Overview

Collect GPU node health, Kubernetes pod status, event logs, and API connectivity into a single diagnostic archive for CoreWeave support tickets. This bundle captures cluster-level resource allocation, failed pod logs, GPU device plugin state, and network reachability so support engineers can diagnose infrastructure issues without requesting additional information. Useful when GPU pods are stuck pending, inference workloads OOM, or node autoscaling behaves unexpectedly.

## Debug Collection Script

```bash
#!/bin/bash
set -euo pipefail
BUNDLE="debug-coreweave-$(date +%Y%m%d-%H%M%S)"
mkdir -p "$BUNDLE"

# Environment check
echo "=== CoreWeave Debug Bundle ===" | tee "$BUNDLE/summary.txt"
echo "Generated: $(date -u +%Y-%m-%dT%H:%M:%SZ)" >> "$BUNDLE/summary.txt"
echo "COREWEAVE_API_KEY: ${COREWEAVE_API_KEY:+[SET]}" >> "$BUNDLE/summary.txt"
echo "KUBECONFIG: ${KUBECONFIG:-default}" >> "$BUNDLE/summary.txt"
echo "kubectl: $(kubectl version --client --short 2>/dev/null || echo 'not found')" >> "$BUNDLE/summary.txt"

# API connectivity
HTTP=$(curl -s -o /dev/null -w "%{http_code}" -H "Authorization: Bearer ${COREWEAVE_API_KEY}" \
  https://api.coreweave.com/v1/namespaces 2>/dev/null || echo "000")
echo "API Status: HTTP $HTTP" >> "$BUNDLE/summary.txt"

# Cluster state
kubectl get nodes -o wide > "$BUNDLE/nodes.txt" 2>&1 || true
kubectl get pods --all-namespaces -o wide > "$BUNDLE/pods.txt" 2>&1 || true
kubectl get events --sort-by=.lastTimestamp > "$BUNDLE/events.txt" 2>&1 || true

# GPU allocation and device plugin status
kubectl describe nodes | grep -A10 "Allocated resources" > "$BUNDLE/gpu-allocation.txt" 2>&1 || true
kubectl get pods -n kube-system -l k8s-app=nvidia-device-plugin -o wide > "$BUNDLE/gpu-plugin.txt" 2>&1 || true

# Failed pod logs
for pod in $(kubectl get pods --field-selector=status.phase=Failed -o name 2>/dev/null); do
  kubectl logs "$pod" --tail=200 > "$BUNDLE/$(basename "$pod")-logs.txt" 2>&1 || true
done

# Rate limit headers
curl -s -D "$BUNDLE/rate-headers.txt" -o /dev/null \
  -H "Authorization: Bearer ${COREWEAVE_API_KEY}" \
  https://api.coreweave.com/v1/namespaces 2>/dev/null || true

tar -czf "$BUNDLE.tar.gz" "$BUNDLE" && rm -rf "$BUNDLE"
echo "Bundle: $BUNDLE.tar.gz"
```

## Analyzing the Bundle

```bash
tar -xzf debug-coreweave-*.tar.gz
cat debug-coreweave-*/summary.txt          # API + env status at a glance
grep -i "error\|fail\|oom" debug-coreweave-*/events.txt  # Critical events
cat debug-coreweave-*/gpu-allocation.txt   # GPU resource pressure
```

## Common Issues

| Symptom | Check in Bundle | Fix |
|---------|----------------|-----|
| GPU pods stuck Pending | `gpu-allocation.txt` shows 0 allocatable GPUs | Request quota increase or switch to available GPU type |
| OOMKilled on inference pod | `events.txt` for OOMKilled entries | Increase memory limits in pod spec; check model size vs allocated RAM |
| Node NotReady | `nodes.txt` status column | Check `events.txt` for kubelet issues; contact CoreWeave if persistent |
| API returns 401 | `summary.txt` shows HTTP 401 | Regenerate API key at CoreWeave dashboard; verify `COREWEAVE_API_KEY` is set |
| NVIDIA device plugin missing | `gpu-plugin.txt` empty or error | Verify namespace `kube-system` has device plugin DaemonSet; redeploy if missing |

## Automated Health Check

```typescript
async function checkCoreWeave(): Promise<void> {
  const key = process.env.COREWEAVE_API_KEY;
  if (!key) { console.error("[FAIL] COREWEAVE_API_KEY not set"); return; }

  const res = await fetch("https://api.coreweave.com/v1/namespaces", {
    headers: { Authorization: `Bearer ${key}` },
  });
  console.log(`[${res.ok ? "OK" : "FAIL"}] API: HTTP ${res.status}`);

  const limit = res.headers.get("x-ratelimit-remaining");
  if (limit) console.log(`[INFO] Rate limit remaining: ${limit}`);
}
checkCoreWeave();
```
