k8s-resource-finder is a simple GO app to look for unused resources, namely, secrets, configmaps, service accounts and persistentvolumeclaims.
Make sure you have select the correct Kubernetes context:
go build -o k8s-resource-finder && ./k8s-resource-finder --namespaces monitoring --namespaces defaultk8s-resource-finder will not change or delete any resource. It is just viewing which pods use what resources.
