Book Description: Production Grade Troubleshooting Master the Art of Debugging Complex Systems with Real-World Scenarios
In the fast-paced world of DevOps, SRE, and Cloud Engineering, downtime isn’t an option. Yet, even the most robust systems encounter mysterious failures, performance bottlenecks, and configuration drift. How do you diagnose, resolve, and prevent these issues before they escalate into full-blown incidents?
Production Grade Troubleshooting is your ultimate field guide to tackling 80 real-world troubleshooting scenarios across 8 critical technologies:
- Ansible (SSH auth, idempotency, Jinja2 errors, slow playbooks)
- GitOps (ArgoCD sync, Flux build errors, drift detection, Sealed Secrets)
- Load Balancers (502/503/504 errors, SSL/TLS, WebSocket, AWS ALB)
- Microservices (mTLS, cascading failures, Kafka lag, DB pool exhaustion)
- Linux VMs (Disk full, OOM killer, SSH lockout, cron failures)
- Terraform (State lock, import conflicts, drift, circular dependencies)
- CI/CD (Docker cache, flaky tests, pipeline hangs, rollback)
- OPA & Sentinel (Policy deny debugging, Gatekeeper audit, Sentinel mocks)
Why This Book? ✅ 80 Battle-Tested Scenarios – Each technology section includes 10 real-world cases you’ll encounter in production.
✅ Structured Troubleshooting – Every scenario follows a clear, actionable format:
- ⚠ Symptom – What you’re seeing (e.g., "502 Bad Gateway errors on ALB").
- Root Cause – The underlying issue (e.g., "Misconfigured health checks").
- Numbered Resolution Steps – Step-by-step fixes with ready-to-use commands in highlighted code blocks.
✅ Production-Grade Focus – No theory, no fluff. Just practical, hands-on solutions for the problems that keep you up at night.
✅ Cross-Technology Coverage – Whether you’re debugging Kubernetes, Terraform, Ansible, or CI/CD pipelines, this guide has you covered.
