Windows worker nodes 'NotReady' after joining the RKE2 server; cni plugin not initialized

[abhinovntap]

Hello Team,

I have just started setting up a RKE2 cluster with windows nodes with below config details, steps followed from the rke2 official docs. However, there are new set of CNI errors coming up after Calico is installed on the Windows VMs.

2 Linux(Ubuntu) nodes(1 Server and 1 agent)
2 Windows 2019 nodes(2 agents)
v1.24.13+rke2r1
Calico v3.25.0
Containerd 1.6.19
GoLang 1.19.1

RKE2-Server :kgn

Any suggestions to fix the issue are appreciated.

The version v1.24.13+rke2r1 is pretty old. The Windows code has been changing quite a bit in the last releases. Could you deploy with a newer version please?

[abhinovntap]

Thank you @manuelbuil . There has been a high priority RKE2 use case with same version and further observed issues with csi-proxy service on windows nodes, hence asked. Any particular version you'd recommend and should channel be 'stable' or 'latest' ?

[manuelbuil]

Both stable and latest are good
