About:
Kor is a command-line interface (CLI) tool written in Go that scans Kubernetes clusters to identify unused or orphaned resources like ConfigMaps, Secrets, and Deployments. It helps reduce cluster clutter and improve security by pinpointing resources no longer referenced by active workloads. Its main value is providing clear, actionable reports to optimize and secure Kubernetes environments.
|
Key Features:
- Scans for unused Kubernetes resources (ConfigMaps, Secrets, Deployments, etc.)
- Provides clear, actionable output in various formats (JSON, YAML)
- Helps improve cluster security and reduce resource waste
- Open-source tool with active community development
|
Use Cases:
- Kubernetes cluster cleanup and cost optimization
- Security auditing by identifying orphaned secrets and configmaps
- Pre-migration or environment consolidation analysis
|
Alternatives:
-
kube-no-trouble
– Also detects deprecated APIs, but Kor focuses specifically on unused resources
-
popeye
– Broader Kubernetes cluster sanitizer and linter, whereas Kor is specialized for unused resource discovery
