Use when

Platform teams who want a first-pass diagnostic layer on top of kubectl, especially useful for on-call triage or onboarding engineers unfamiliar with K8s internals.

Avoid when

Teams without any Kubernetes footprint, or organizations that prohibit sending cluster metadata to third-party LLM APIs without heavy review.

What is K8sGPT?

K8sGPT is a CNCF sandbox project that diagnoses Kubernetes clusters by running a suite of analyzers against common failure modes — CrashLoopBackOffs, failing probes, pending pods, misconfigured services — and then passes the findings to an LLM for natural-language explanations and remediation advice. It's typically run locally, in CI, or as an in-cluster operator. Most useful for SREs who want to shorten the loop between kubectl describe and root cause.

Key features

25+ built-in Kubernetes analyzers
Pluggable LLM backends (OpenAI, local models)
In-cluster operator mode with CRDs
Anonymization of cluster data before inference
Integration with Trivy and Prometheus
