Book synopsis

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 Labs

Every 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 Out

Unlike 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.
