Cloud-Native DevOps with Docker & Kubernetes : Build, Secure, and Scale with Helm, ArgoCD, and GitOps

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 InsideDocker & Container SecurityLearn how to build optimized, secure images with multi-stage builds, SBOMs, Cosign signing, and Trivy scanning.Kubernetes Fundamentals to ProductionMaster deployments, services, RBAC, Pod Security, Namespaces, and run workloads across EKS, GKE, and AKS.GitOps with ArgoCDImplement declarative, self-healing deployments with ApplicationSets, App-of-Apps, and progressive delivery.Helm & Kustomize Golden PathsStandardize deployments using reusable templates and overlays for dev, staging, and production environments.CI/CD AutomationBuild secure pipelines with GitHub Actions, integrating SBOMs, image scanning, and Helm chart updates.Observability & SLO MonitoringDeploy Prometheus, Grafana, Loki, and OpenTelemetry to measure latency, error rates, and service health.Security HardeningApply RBAC, Kyverno/OPA policies, NetworkPolicies, and SealedSecrets for compliance and zero-trust workloads.Scaling & FinOpsEnable HPA, VPA, and Cluster Autoscaler, while tracking costs with Kubecost/OpenCost.Chaos EngineeringValidate resilience with LitmusChaos pod deletes, node drains, and network failures. Platform Engineering & IDPsDesign 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 ForBeginners → 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.
