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.

Overview of the OpenFaaS framework

OpenFaaS (FaaS standing for functions as a service) is a framework for creating serverless functions using the Docker and Kubernetes container technologies. Any process can be packaged as a function, allowing the consumption of a variety of web events without having to write boilerplate code over and over. It’s an open source initiative that’s gaining a lot of traction in the community.

Some of the key advantages of the OpenFaaS framework are the following:

  • Running functions on any infrastructure without concern of lock-in with an open source functions framework.
  • Creating functions in any programming language and packaging them in Docker/OCI containers.
  • Built-in UI, robust CLI, and one-click installation make it simple to use.
  • Scale as you go – handle traffic spikes and scale down when not in use.
  • A community edition and a pro edition are available along with production support.
