1. Introduction

MicroK8s is a lightweight, powerful Kubernetes distribution designed for developers and DevOps to create a fast and efficient environment for deploying IoT applications. It is especially useful in edge computing scenarios where resources are limited.

2. MicroK8s Overview

3. IoT Deployment with MicroK8s

3.1 Installation

To install MicroK8s, use the following command:

sudo snap install microk8s --classic

3.2 Enabling Add-ons

MicroK8s comes with several add-ons that enhance its capabilities. To enable an add-on, use:

3.3 Deploying an IoT Application

To deploy an IoT application, prepare a Kubernetes deployment YAML file. Here’s an example for a simple IoT sensor application:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: iot-sensor
spec:
  replicas: 2
  selector:
    matchLabels:
      app: iot-sensor
  template:
    metadata:
      labels:
        app: iot-sensor
    spec:
      containers:
      - name: sensor
        image: my-iot-sensor-image
        ports:
        - containerPort: 80

To deploy the application, run:

microk8s kubectl apply -f deployment.yaml
