Getting Started with K8sGPT: An AI‑Powered Cloud‑Native Kubernetes Diagnostic Tool

K8sGPT is a cutting‑edge cloud‑native AI tool that empowers Kubernetes SREs by scanning clusters and presenting diagnostics in plain English, leveraging ChatGPT‑style capabilities to offer human‑friendly remediation suggestions.

Prerequisite: Access to a Kubernetes cluster (e.g., Minikube, Kind, GKE, EKS, AKS, or a custom setup).

Installation: The simplest method uses Homebrew:

brew tap k8sgpt-ai/k8sgpt

brew install k8sgpt

Quick‑Start Steps:

Run k8sgpt generate to obtain an OpenAI API key (opens a browser for key generation; other providers can be used later).

Configure the key with k8sgpt auth (or provide it directly via --password).

Optionally manage active filter sets using k8sgpt filters (all filters run by default).

Start a scan with k8sgpt analyze, which examines the Kubernetes configuration and returns a summary of any issues.

For detailed explanations, add the --explain flag to the k8sgpt analyze command.

View results in JSON format for deeper insight, e.g., k8sgpt analyze -o json --explain -filter=Pod | jq ..

K8sGPT includes built‑in analyzers such as podAnalyzer, pvcAnalyzer, rsAnalyzer, serviceAnalyzer, eventAnalyzer, and ingressAnalyzer, with optional add‑ons like hpaAnalyzer and pdbAnalyzer, and supports custom analyzer creation.
