-Since kpexec uses kubectl internally, **kubectl** installation and **kubeconfig** files must be properly configured before using kpexec. Whenever kpexec is executed, kpexec creates a **cnsenter (Container Namespace Enter) pod** to executes cnsenter. cnsenter is a command to exec command in the target container. The cnsenter pod must be created with **hostPID** and **Privileged** Option. Therefore, before using kpexec, you should check if the pod options mentioned are available in your kubernetes cluster.
