Kubeasz
Kubeasz is an automation framework designed for the lifecycle management of production-grade Kubernetes clusters. It functions as an Ansible-based provisioner that orchestrates the installation, scaling, and maintenance of cluster components across distributed Linux nodes. By utilizing inventory-driven management and role-based task modularization, the project ensures that infrastructure configurations remain consistent and reproducible across diverse environments.
The platform distinguishes itself through its focus on automated system administration and operational continuity. It provides built-in capabilities for performing version upgrades and rotating security certificates without interrupting active services. Furthermore, the tool integrates disaster recovery workflows, allowing administrators to create snapshots of the cluster state and restore the entire environment to a functional condition following data loss or system corruption.
Beyond core lifecycle operations, the project covers a broad range of infrastructure tasks including network traffic routing and load balancing configuration. It employs template-based generation and idempotent state reconciliation to manage service settings and ensure that target nodes align with defined infrastructure requirements. The project is distributed as a collection of Ansible playbooks, providing a structured approach to managing the full operational lifecycle of a Kubernetes cluster.
