Identify Active Kubeconfig File in Kubernetes

To find out which kubeconfig file is being used by Kubernetes, check the `KUBECONFIG` environment variable or the default location. You can use the following command to display the location of the current kubeconfig file:

kubectl config view --minify -o jsonpath='{.current-context}'

If `KUBECONFIG` is not set, Kubernetes uses the default path `~/.kube/config`.
