k8s-1abel - Kubernetes YAML/JSON survival kit
The tool that helps you survive painful YAML days.
Kubernetes uses label selectors to create references between different resources such as services referring to pods or deployments. All references are loosely coupled using label names. Typos can lead to stale references between resources and can be very hard to find.
k8s-1abel ("k8s-label") validates all LabelSelector in Kubernetes resources such as Services, and automatically points out label references that cannot be associated with a target pod or target deployment.
Example - Validate all service references
