RKE2 Windows Troubleshooting

High Level Notes

• For any and all RKE2 Windows Clusters, v1.22.x or higher of RKE2 needs to be used. This is due to a Calico 3.19.x bug in v1.21.x of RKE2 that Tigera will not backport.
• The minor version of Calico was changed midway through the RKE2 v1.22 lifecycle.
  • rke2 v1.22.3+rke2r1 through v1.22.6+rke2r1 have Calico 3.20.x (3.20.1 for v1.22.3+rke2r1 only and then 3.20.2 until v1.22.7+rke2r1)
  • rke2 v1.22.7+rke2r1 and up have Calico 3.21.4 (or higher)

How to configure max pods for the SUSE Rancher Kubernetes distributions

Considerations when Increasing the Max Pod Count

Changing the max-pods on an active cluster with workloads is generally a safe procedure when target number of max-pods is <=250. When the goal number of max-pods is >250, the additional considerations mentioned above require a deletion of all currently running pods.

If increasing max-pods to >250, there are additional considerations and changes required. The in-cluster IP management configuration needs to be modified as the default is a /16 split into one /24 for each node in the cluster. This comes to a limit of about 256 nodes with roughly 253 pods per node.

--max-pods int32 Default: 110
