Quick Start Guide
- Generate an API Key: Start by generating an API key from OpenAI by running
k8sgpt generate. - Authenticate: Use
k8sgpt auth addto set up authentication, or use the--passwordflag to input the password directly. - Manage Filters: Run
k8sgpt filtersto manage filters used by the analyzer, all are active by default. - Run a Scan: Use
k8sgpt analyzeto initiate a scan. - Get Explanations: For detailed explanations, run
k8sgpt analyze --explain. - Access Documentation: Obtain official Kubernetes documentation by executing
k8sgpt analyze --with-doc.
Analyzers in k8sgpt
k8sgpt's analyzers are the backbone of its diagnostic capabilities. They employ various built-in analyzers to evaluate cluster health, such as:
- Pod Analyzer
- PVC Analyzer
- ReplicaSet Analyzer
- Service Analyzer
- Event Analyzer
- Ingress Analyzer
- StatefulSet Analyzer
- Deployment Analyzer
- CronJob Analyzer
- Node Analyzer
These analyzers provide comprehensive assessments of the cluster, helping developers and IT professionals maintain high-performance Kubernetes environments efficiently.
In conclusion, k8sgpt is an indispensable tool for anyone managing Kubernetes clusters, offering advanced diagnostic capabilities powered by AI and a comprehensive set of analyzers to ensure optimal cluster performance. Its straightforward operational setup and features make it accessible for users at all levels.
