i am trying to using a MicroServiceSimulator (https://github.com/mSvcBench/MicroServiceSimulator/blob/main/Docs/Manual.md) with Kind and Kubernetes. After installed all, i lunch "kubectl get pods" (with root) but i have this error:

The connection to the server localhost:8080 was refused - did you specify the right host or port?

How i can fix it?

O.S: Ubuntu 21.01

Thank you
