A comprehensive walkthrough for building a multicluster GitOps platform using popular open source tools in the Kubernetes space, focusing on choosing a cloud provider, selecting a Git provider, establishing a platform domain and DNS provider, defining Infrastructure as Code, selecting a GitOps engine, and defining management pillars.
This article provides a cheatsheet on the Infrastructure as Code (IaC) landscape, highlighting the benefits of scalable infrastructure provisioning in terms of availability, scalability, repeatability, and cost-effectiveness. It discusses strategies such as containerization, container orchestration, and tools like Terraform, Kubernetes, and Ansible. The article also introduces GitOps as a method for automating infrastructure updates through Git workflows and CI/CD.
An introduction to using Terraform for Infrastructure as Code (IaC) practices, providing beginners with a guide to start with Terraform.
Diagrams is a tool that lets you draw cloud system architecture using Python code, supporting major cloud providers and on-premise nodes.
Eran Bibi, co-founder and chief product officer at Firefly, discusses two open-source AI tools, AIaC and K8sGPT, that aim to reduce DevOps friction by automating tasks such as generating IaC code and troubleshooting Kubernetes issues.
- AIaC (AI as Code):
An open source command-line interface (CLI) tool that enables developers to generate IaC (Infrastructure as Code) templates, shell scripts, and more using natural language prompts.
Example: Generating a secure Dockerfile for a Node.js application by describing requirements in natural language.
Benefits: Reduces the need for manual coding and errors, accelerating the development process.
- K8sGPT:
An open source tool developed by Alex Jones within the Cloud Native Computing Foundation (CNCF) sandbox.
Uses AI to analyze and diagnose issues within Kubernetes clusters, providing human-readable explanations and potential fixes.
Example: Diagnosing a Kubernetes pod stuck in a pending state and suggesting corrective actions.
Benefits: Simplifies troubleshooting, reduces the expertise required, and empowers less experienced users to manage clusters effectively.

An in-depth exploration of using Large Language Models (LLMs) to generate Terraform code for infrastructure as code (IaC), analyzing the capabilities and limitations of LLMs in this domain.
All models struggled with:
- Variable usage (hardcoded values)
- IAM configuration (permissions)
- Security group management
- Target group configuration
While LLMs are promising for IaC, they can be helpful tools for developers.
