What is MicroK8s?
MicroK8s is a lightweight and easy-to-install Kubernetes distribution developed by Canonical for simplified local development and testing. It enables users to quickly set up a single-node Kubernetes cluster on their machines, making it accessible to developers and administrators. With features like easy installation, single-node deployment, and optional add-ons, MicroK8s provides a convenient way to experiment with Kubernetes in resource-constrained environments. It is distributed as a snap package, allowing for simple installation and updates, and is suitable for scenarios where a full-scale production Kubernetes cluster is not required.
