I have kubernetes cluster.every thing work fine. but after 8 days when i run kubectl get pods it shows:
The connection to the server <host>:6443 was refused - did you specify the right host or port?I have one master and one worker. I run them in my lab without any cloud.
systemctl kubelet status
show **node not found**my /etc/hosts was checked and it is correct
most likely that the servers are rebooted. i had similar problem. check kubelet logs on master server and take action.
if you can share the kubelet logs then we will be able to offer you further help
verify /var/log/messages to get further information about the error
or
systemctl status kubelet
or
Alternately journalctl will also show the details.
Reboot itself should not be a problem - but if you did not disabled swap permanently reboot will enable swap again and API server will not launch - it could be first shot.
Second - check free disk space, API server will not respond if disk is full (will raise disk pressure event and will try to evict pods).
If it will not help - please add logs from Kubelet (systemctl and journalctl).
i have lack of hardware. I run this command to solve the issue
sudo -i
swapoff -a
exit
strace -eopenat kubectl version
