KUBERNETES for Professionals

You can already deploy a Deployment. Now learn to run one that a real business - and a real audit - can actually depend on.

This is the book for engineers who've moved past "it works on my cluster" and into the much harder territory of production: security that would survive a genuine compliance audit, observability that tells you the truth at 2 a.m., and delivery practices that let you ship safely and often instead of holding your breath every deploy.

The direct, comprehensive continuation of Kubernetes for Beginners - written for platform engineers, SREs, security engineers, and senior developers ready for genuine production depth, not another surface-level overview.

What's inside - 26 chapters, seven parts, zero filler:

• Custom Resource Definitions and Operators - extend Kubernetes to automate your own operational knowledge
• CNI internals, service mesh (Istio and Linkerd), and genuine zero-trust networking
• RBAC done right, Pod Security Standards, Policy as Code with OPA and Kyverno, and full supply chain security - scanning, signing, SBOMs
• A complete observability stack: Prometheus, Grafana, distributed tracing, and the SLO/error-budget discipline real SRE teams actually run on
• Autoscaling in depth (HPA, VPA, Cluster Autoscaler, KEDA), performance tuning grounded in real measurement, and FinOps that keeps your cloud bill honest
• Progressive delivery, GitOps with Argo CD and Flux, Helm chart authoring at scale, and disaster recovery that's actually been tested
• Three complete, realistic architecture case studies across finance, media, and B2B SaaS - showing exactly how every piece combines under real business constraints

Every chapter delivers production-grade, complete configuration examples - never simplified toy YAML - and closes with a Production Troubleshooting Checklist built for the moment something breaks under real pressure.

Perfect for: platform and infrastructure engineers, SREs, security engineers, senior backend developers stepping into ownership of their own production environment, and anyone preparing for the CKA, CKAD, or CKS certification exams.

Depth you can actually use. Judgment you can actually trust. This is Kubernetes for the job, not just the job interview.
