MicroK8s in Practice
"MicroK8s in Practice" **MicroK8s in Practice** is the definitive guide for engineers, architects, and technology leaders seeking to master Kubernetes at the edge, in development, and within hybrid cloud environments. Through methodical exploration of MicroK8s’ architecture, this book provides a deep dive into its unique design principles, resource optimization strategies, and modular snap-based packaging. Readers will gain a comprehensive understanding of core components, add-on internals, and the nuanced trade-offs that distinguish MicroK8s from upstream Kubernetes distributions—making it invaluable for those aiming to design scalable, resilient, and efficient platforms. Practical in scope and advanced in detail, the book addresses every stage of the MicroK8s lifecycle, from installation and initial cluster setup to multi-node orchestration, upgrades, disaster recovery, and persistent state management. It unpacks critical topics such as secure networking, storage integration, observability, and compliance—revealing strategies for service exposure, integrated monitoring, logging, and security best practices. Real-world patterns for workload orchestration, GitOps automation, serverless extension, and multi-tenancy empower readers to build flexible, production-ready Kubernetes solutions tailored for both cloud data centers and resource-constrained edge deployments. With a strong emphasis on troubleshooting, optimization, and operational excellence, **MicroK8s in Practice** presents actionable guidance for diagnosing and resolving complex issues, stress testing clusters, and upholding robust security postures. Readers will find exhaustive checklists, best practices, and design patterns for deploying MicroK8s in mission-critical environments. Whether you are developing edge applications, architecting hybrid cloud infrastructures, or leading a DevOps team, this book equips you with the expertise to confidently design, operate, and scale next-generation Kubernetes platforms with MicroK8s at their core.

Release Date: 2022-09-30
A step-by-step, comprehensive guide that includes real-world use cases to help you successfully develop and run applications and mission-critical workloads using MicroK8s Key Features An easy-to-follow guide that helps you get started with MicroK8s and other Kubernetes components Understand the key concepts and constraints for building IoT and edge architectures Get guidance on how to develop and deploy use cases and examples on IoT and edge computing platforms Book DescriptionAre you facing challenges with developing, deploying, monitoring, clustering, storing, securing, and managing Kubernetes in production environments as you're not familiar with infrastructure technologies? MicroK8s - a zero-ops, lightweight, and CNCF-compliant Kubernetes with a small footprint is the apt solution for you. This book gets you up and running with production-grade, highly available (HA) Kubernetes clusters on MicroK8s using best practices and examples based on IoT and edge computing. Beginning with an introduction to Kubernetes, MicroK8s, and IoT and edge computing architectures, this book shows you how to install, deploy sample apps, and enable add-ons (like DNS and dashboard) on the MicroK8s platform. You’ll work with multi-node Kubernetes clusters on Raspberry Pi and networking plugins (such as Calico and Cilium) and implement service mesh, load balancing with MetalLB and Ingress, and AI/ML workloads on MicroK8s. You’ll also understand how to secure containers, monitor infrastructure and apps with Prometheus, Grafana, and the ELK stack, manage storage replication with OpenEBS, resist component failure using a HA cluster, and more, as well as take a sneak peek into future trends. By the end of this book, you’ll be able to use MicroK8 to build and implement scenarios for IoT and edge computing workloads in a production environment.What you will learn Get a holistic view of MicroK8s features using a sample application Understand IoT and edge computing and their architecture constraints Create, scale, and update HA Raspberry Pi multi-node clusters Implement AI/ML use cases with the Kubeflow platform Work with various networking plugins, and monitoring and logging tools Perform service mesh integrations using Istio and Linkerd Run serverless applications using Knative and OpenFaaS frameworks Secure your containers using Kata and strict confinement options Who this book is for This book is for DevOps and cloud engineers, SREs, and application developers who want to implement efficient techniques for deploying their software solutions. It will also be useful for technical architects and technology leaders who are looking to adopt cloud-native technologies. A basic understanding of container-based application design and development, virtual machines, networking, databases, and programming will be helpful for using this book.
Minikube in Practice
"Minikube in Practice" "Minikube in Practice" is the definitive guide for developers, DevOps engineers, and platform specialists seeking to master local Kubernetes clusters. This comprehensive volume meticulously unpacks Minikube’s architecture and its critical role within the Kubernetes ecosystem, offering a deep exploration of cluster internals, networking, storage, and multi-profile management. The reader will come away with a clear understanding of installation workflows across major operating systems, advanced customization of cluster resources, and strategies for persistent storage, networking, and integration with custom build pipelines. Going far beyond the basics, the book delves into real-world operational patterns, covering automation of cluster lifecycle management, advanced health checks, scaling of multi-node environments, upgrade/downgrade procedures, and efficient resource reclamation. Test-driven deployment scenarios are illustrated through practical examples—deploying microservices, stateful applications, CI/CD workflows, and blue/green as well as canary releases. Every aspect of cloud-native application development and debugging is covered in detail, supplemented by best practices for working with Kubernetes manifests, Helm charts, declarative management, and secure configuration with Secrets and ConfigMaps. "Minikube in Practice" also equips readers with advanced skills in networking, observability, security, and custom extension development. Master the art of configuring ingress controllers, service mesh prototyping, and network policy validation, as well as integrating leading monitoring and tracing tools for full cluster observability. Dedicated chapters guide you through implementing RBAC, compliance testing, and vulnerability scanning in local environments, all while extending Minikube with custom add-ons, device plugins, and hybrid multi-cluster topologies. With in-depth coverage of performance tuning, benchmark strategies, and the boundaries of local Kubernetes emulation, this book is an invaluable resource for building robust, production-like development environments on your workstation.
