What is MicroK8s and How to Use it?

MicroK8s, a lightweight and versatile Kubernetes distribution, has gained popularity for its ease of use and efficient deployment capabilities. Whether you're a seasoned developer or just getting started with container orchestration, MicroK8s provides a hassle-free solution for managing containerized applications. In this article, we'll explore what MicroK8s is and guide you through the process of using it effectively.

Understanding MicroK8s:

MicroK8s, short for Micro Kubernetes, is a single-node Kubernetes cluster that simplifies the deployment and management of containerized applications. It is designed to be lightweight, quick to install, and suitable for development, testing, and small-scale production environments. Unlike traditional Kubernetes distributions, MicroK8s is minimalistic yet powerful, making it an ideal choice for users looking for a straightforward Kubernetes experience.


Before diving into MicroK8s, you'll need to install it on your machine. The process is remarkably straightforward. Open your terminal and enter the following command:

sudo snap install microk8s --classic

This command will install MicroK8s using the Snap package manager on Linux. If you're using a different operating system, refer to the official MicroK8s documentation for installation instructions.

Starting and Stopping MicroK8s:

Once MicroK8s is installed, you can start and stop the Kubernetes cluster using the following commands:

Start MicroK8s:

microk8s start

Stop MicroK8s:

microk8s stop

These commands allow you to easily control the lifecycle of your MicroK8s cluster, ensuring that resources are utilized efficiently when needed and turned off when not in use.

Accessing the Kubernetes Dashboard:

MicroK8s provides a convenient web-based dashboard for managing your Kubernetes cluster. Access it by running the following command:

microk8s dashboard-proxy

This will open the Kubernetes dashboard in your default web browser. From the dashboard, you can monitor cluster resources, deploy applications, and manage various aspects of your Kubernetes environment.

Deploying Applications:

MicroK8s simplifies the process of deploying applications by providing pre-packaged add-ons. For instance, deploying the DNS service can be achieved with a single command:

microk8s enable dns

This command ensures that your Kubernetes cluster has a functioning DNS service, a critical component for proper application communication.

Scaling Your Deployment:

If your application demands more resources, MicroK8s allows you to easily scale your deployment. For example, to scale a deployment named "myapp" to three replicas, use the following command:

microk8s kubectl scale --replicas=3 deployment/myapp

This scales the specified deployment to three replicas, distributing the workload and enhancing application availability.

MicroK8s provides a user-friendly and efficient way to work with Kubernetes, making it accessible for developers and administrators alike. From installation to deployment, the streamlined commands and features make managing containerized applications a seamless process. Whether you're developing, testing, or deploying in a production environment, MicroK8s empowers you with a lightweight yet robust Kubernetes solution.
