IoT Edge Computing with MicroK8s

By: Karthikeyan Shanmugam

Overview of this book

Are 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.

Part 4: Deploying and Managing Applications on MicroK8s

This part focuses on the deployment and management aspects of typical IoT/Edge computing applications, such as setting up storage replication for your stateful applications, implementing a service mesh for cross-cutting concerns and a high availability cluster to withstand a component failure and continue to serve workloads without interruption, configuring containers with workload isolation, and running secured containers in isolation from a host system.

This part of the book comprises the following chapters:

  • Chapter 11, Managing Storage Replication with OpenEBS
  • Chapter 12, Implementing Service Mesh for Cross-Cutting Concerns
  • Chapter 13, Resisting Component Failure Using HA Cluster
  • Chapter 14, Hardware Virtualization for Securing Containers
  • Chapter 15, Implementing Strict Confinement for Isolated Containers
  • Chapter 16, Diving into the Future
