Rancher managed RKE2 clusters stuck in "Waiting for probes: kube-controller-manager, kube-scheduler"

This document (000021371) is provided subject to the disclaimer at the end of this document.


Rancher <2.7.5


Downstream RKE2 clusters in Rancher GUI stuck with status:
"Waiting for probes: kube-controller-manager, kube-scheduler" 


Stop the RKE2 server:

systemctl stop rke2-server

Remove the .crt and .key file in the respective tls directories:

rm /var/lib/rancher/rke2/server/tls/kube-controller-manager/kube-controller-manager.{crt,key}


rm /var/lib/rancher/rke2/server/tls/kube-scheduler/kube-scheduler.{crt,key}

Perform a certificate rotation:

rke2 certificate rotate

Restart RKE2 server:

systemctl start rke2-server




This issue should be fixed in 2.7.5 as per code changes the certificates that may result in cluster getting stuck on upgrade are now also rotated when using "Rotate Certificates" feature.

It's highly recommended to rotate certificates periodically (at least once a year) to ensure they do not expire.
