• Run k8sgpt analyze to run a scan.
• And use k8sgpt analyze --explain to get a more detailed explanation of the issues.

Filter by namespace

k8sgpt analyze --explain --filter=Pod --namespace=default

Output to JSON

k8sgpt analyze --explain --filter=Service --output=json

Upcoming major milestones

• Multiple AI backend support
• Custom AI/ML model backend support
• Custom analyzers

What about kubectl-ai?

The kubectl-ai project uses AI to create manifests and apply them to the cluster. It is not what we are trying to do here, it is focusing on writing YAML manifests.

K8sgpt is focused on triaging and diagnosing issues in your cluster. It is a tool for SRE, Platform & DevOps engineers to help them understand what is going on in their cluster. Cutting through the noise of logs and multiple tools to find the root cause of an issue.

Configuration

k8sgpt stores config data in ~/.k8sgpt.yaml the data is stored in plain text, including your OpenAI key.
