Question
List all the endpoints in kube-system namespace and save the output to /tmp/endpoints.txt
Answer
Endpoints usually represent IP address(es) of Pod(s) mapped with the services.
These are defined as separate resources in Kubernetes cluster. They can be called either using endpoints or ep with kubectl command:
kubectl get endpoints -n kube-system > /tmp/endpoints.txt
kubectl get ep -n kube-system > /tmp/endpoints.txt
