Hi, have a question on creating custom scheduler. Getting the below error when creating custom scheduler. I have changed the port to 10251 instead of 10259. Not sure why am getting the below error
root@controlplane:~# kubectl logs -f my-scheduler -n kube-system
I0611 00:37:18.364066 1 serving.go:331] Generated self-signed cert in-memory
failed to create listener: failed to listen on 127.0.0.1:10259: listen tcp 127.0.0.1:10259: bind: address already in use
