K3s Ansible

Overview

Building a highly available (HA) Kubernetes cluster can be quite a task, but with the automated K3s cluster installation using kube-vip and MetalLB, it becomes significantly simpler. This setup leverages Ansible to streamline the process, ensuring that users can configure their clusters without extensive manual intervention. This solution not only enhances efficiency but also improves the reliability of your deployments by making use of the latest technologies in the Kubernetes ecosystem.

The playbook allows users to effortlessly set up an HA K3s cluster that is compatible with common operating systems such as Debian, Ubuntu, and Rocky. By utilizing kube-vip for load balancing and MetalLB for service load balancers, this tool ensures that your Kubernetes control plane and its associated services run smoothly and efficiently.
