k8sgpt is a tool for scanning your Kubernetes clusters, diagnosing, and triaging issues in simple English.

It has SRE experience codified into its analyzers and helps to pull out the most relevant information to enrich it with AI.

Setup k8sgpt package:

Download K8sgpt for ubuntu:

curl -LO https://github.com/k8sgpt-ai/k8sgpt/releases/download/v0.4.33/k8sgpt_amd64.deb

Install:

dpkg -i k8sgpt_amd64.deb

Kubernetes can sends the cluster diagnostics to OpenAI API's, but it is paid so we can use Local LLM.

Install k8sgpt on cluster or on local machine but make sure that cluster should be accessible via kubectl command.

Setup Local LLM if not exists.
