Workflow: Pod Debugging

Phase 1: Assessment

Step 1.1: List Pods

CopyUse k8s_pods with:
- namespace: Target namespace (or default)

Check for:

• Pod status (Running, Pending, Failed)
• Restart count
• Age

Step 1.2: Check Services

CopyUse k8s_services to verify:
- Service endpoints
- Port mappings
- Selectors

Phase 2: Investigation

Step 2.1: Pod Details

CopyUse k8s_pod_describe with:
- pod_name: Target pod
- namespace: Pod namespace

Look for:
- Events (warnings, errors)
- Container status
- Resource limits
- Node assignment

Step 2.2: View Logs

CopyUse k8s_pod_logs with:
- pod_name: Target pod
- container: Container name (if multi-container)
- tail: 100 (last N lines)
- previous: true (if crashed)

Phase 3: Common Fixes

Quick Reference

Pod States

CopyPending    → Waiting for scheduling
Running    → Container(s) running
Succeeded  → Completed successfully
Failed     → Container exited with error
Unknown    → State cannot be determined

Common Commands

Copy# Get all resources
kubectl get all -n namespace

# Watch pods
kubectl get pods -w

# Exec into pod
kubectl exec -it pod-name -- /bin/sh

Best Practices

✅ GOOD:

• Set resource requests/limits
• Use liveness/readiness probes
• Check events on failures
• Use namespaces for isolation

❌ BAD:

• No resource limits
• Ignore probe failures
• Delete pods without investigation
• Run everything in default namespace

Checklist

• kubectl configured
• Namespace specified
• Pod status checked
• Events reviewed
• Logs examined
• Resources adequate
