About the Book
Cloud-Native DevOps with Docker & Kubernetes: Build, Secure, and Scale with Helm, ArgoCD, and GitOps is your complete, hands-on guide to mastering the modern DevOps toolkit. Whether you're a beginner exploring containers, an intermediate engineer deploying microservices, or a seasoned professional building internal developer platforms, this book takes you step-by-step from fundamentals to production-ready, enterprise-grade platforms.
What You'll Learn Inside
Docker & Container Security
Learn how to build optimized, secure images with multi-stage builds, SBOMs, Cosign signing, and Trivy scanning.
Kubernetes Fundamentals to Production
Master deployments, services, RBAC, Pod Security, Namespaces, and run workloads across EKS, GKE, and AKS.
GitOps with ArgoCD
Implement declarative, self-healing deployments with ApplicationSets, App-of-Apps, and progressive delivery.
Helm & Kustomize Golden Paths
Standardize deployments using reusable templates and overlays for dev, staging, and production environments.
CI/CD Automation
Build secure pipelines with GitHub Actions, integrating SBOMs, image scanning, and Helm chart updates.
Observability & SLO Monitoring
Deploy Prometheus, Grafana, Loki, and OpenTelemetry to measure latency, error rates, and service health.
Security Hardening
Apply RBAC, Kyverno/OPA policies, NetworkPolicies, and SealedSecrets for compliance and zero-trust workloads.
Scaling & FinOps
Enable HPA, VPA, and Cluster Autoscaler, while tracking costs with Kubecost/OpenCost.
Chaos Engineering
Validate resilience with LitmusChaos pod deletes, node drains, and network failures.
Platform Engineering & IDPs
Design and operate Internal Developer Platforms (IDPs) with Backstage, Crossplane, and GitOps golden paths.
Hands-On Practice LabsEvery chapter includes practice labs that guide you through:
Building and securing a containerized microservice.
Deploying a multi-service app on a managed Kubernetes cluster.
Automating a secure CI/CD pipeline.
Implementing unified observability dashboards.
Hardening a Kubernetes namespace with policies and secrets.
Configuring autoscaling for real workloads.
Deploying with GitOps across multiple clusters.
Running a full-stack, end-to-end production platform project.
Who This Book Is For
Beginners → who want a structured, practical entry point into containers, Kubernetes, and DevOps.
Intermediate Engineers → ready to move from lab clusters to production-ready deployments.
Senior Professionals & Platform Engineers → building scalable, secure, and cost-optimized IDPs.
Why This Book Stands OutUnlike generic introductions, this book is purely practical, hands-on, and up-to-date for 2025+. It covers not just how to deploy apps, but how to secure, scale, and operate them under real production constraints - the exact skills hiring managers and teams demand today.
By the end, you won't just "know Kubernetes." You'll be able to design, build, and run cloud-native DevOps platforms with confidence.
Build It. Secure It. Scale It.
If you want to master modern DevOps practices and become proficient at Cloud-Native Engineering with Docker, Kubernetes, Helm, ArgoCD, and GitOps, this is the only book you need.
