KubeNodeNotReady#

Lot of triggers can cause this alert.

Troubleshooting hints :

  • kubectl get nodes : check the node status in the cluster
  • kubectl describe <node> : kubernetes can give some informations
  • Check the node events in the webui of the provider. Like FE.
  • Try to ssh on the node from the bastion. If you the connection is successful, check the logs in /var/log/ or with dmesg -T, journalctl
  • Check Grafana

Solutions#

Reboot the node. PS: If the node is less loaded compared to the others, try to evacuate some pods in this node.
