Ksctl: Simplified Kubernetes Clusters Lifecycle Management

Making Kubernetes accessible to developers

📖 Overview

Ksctl simplifies the management of Kubernetes clusters across different cloud providers through a unified interface. It focuses on creating cost-efficient and sustainable Kubernetes infrastructure by intelligently optimizing resource selection and deployment. It eliminates the need for multiple cloud-specific CLIs (AWS, Azure, etc.) and handles the complex infrastructure setup for you.

✨ Key Features

• Unified Management Interface - Manage clusters on multiple cloud providers with a single CLI.
• Rapid Cluster Creation - Deploy production-ready clusters in 5-10 minutes with ksctl create.
• Multi-Cloud & Cluster Types - Supports self-managed (K3s, Kubeadm) and managed clusters (AKS, EKS, GKE) across major clouds.
• Sustainability Focus - Intelligently selects regions and instances with lower carbon footprints and higher renewable energy usage.
• Cost Optimization - Reduces cloud expenses through smart resource selection and dynamic region switching.
• Simplified Lifecycle Management - Create, delete, scale, and switch between clusters easily.
• Application Stack Deployment - Deploy common applications like GitOps tools and monitoring solutions.

🏗️ Architecture

🧩 Components

The ksctl ecosystem consists of these main components:

• ksctl - Core component for cluster provisioning, Kubernetes bootstrap, cost optimization, and addon management
• ksctl/cli - End-user CLI interface for cluster and addon operations
• Ksctl Cluster Management (kcm) - Kubernetes controller for managing ksctl-specific cluster addons
• Ksctl Application (ka) - Controller for ksctl application stack functionality

🚀 Current Capabilities

• Cluster Operations

  • Create, delete, and get cluster infrastructure details
  • State storage in local system or MongoDB
  • Manual scaling up and down via CLI
  • Switch between clusters
  • Wasm and application stack deployment

• Supported Cluster Types

  • Self-Managed HA Clusters:
    • K3s
    • Kubeadm
  • Cloud Managed Clusters:
    • AKS (Azure)
    • EKS (AWS)

• Lifecycle Management

  • Deploy Wasm workloads
  • Common application stack deployment (GitOps, monitoring, etc.)
