IP address K3S goes weird

[rthamrin]

I run k3s version v1.21.7+k3s1 (ac70570) on ubuntu 21.10
I set internal and external IP addresses through k3s.service.

#vim /etc/systemd/system/k3s.service 

everything goes right until I try to remove the IP address. I remove the setting that I set before, and restart everything, but seems the IP address won't go.

#restart daemon-reload
#restart k3s.service
#restart NetworkManager
#reboot
even disable the Ethernet 

I checked through

#kubectl get nodes -o wide

the IP address is still there. how can I remove the IP address?

NB: I have some K3S-agent connected to internal IP address

Restarting without the --node-external-ip flag won't cause the annotations or address values to be unset. What specifically are you trying to do?

I want to remove my external-Ip address from my node, my 192.168.77.112 IP address

# kubectl get nodes -o wide

There's not currently a good way to unset that once you've set it. You might be able to get away with deleting the node and then restarting k3s to recreate it, but I would test that somewhere non-critical first.

is there any update for this?
