It is the rebuilt cluster and running fine. However, there is also only 1 calico-node and FYI. Thanks!

NAMESPACE NAME DESIRED CURRENT READY UP-TO-DATE AVAILABLE NODE SELECTOR AGE
kube-system calico-node 3 3 3 3 3 kubernetes.io/os=linux 23d
ingress nginx-ingress-microk8s-controller 5 5 3 5 3 16h
kube-system csi-smb-node 3 3 3 3 3 kubernetes.io/os=linux 15h
kube-system csi-smb-node-win 2 2 2 2 2 kubernetes.io/os=windows 15h

22

This is the state before enabling rbac?

24

Yes, rbac is not enabled yet

25

Looking at this output, im guessing you have 3 linux nodes and 2 windows nodes?

NAMESPACE NAME DESIRED CURRENT READY UP-TO-DATE AVAILABLE NODE SELECTOR AGE
kube-system calico-node 3 3 3 3 3 kubernetes.io/os=linux 23d
ingress nginx-ingress-microk8s-controller 5 5 3 5 3 16h
kube-system csi-smb-node 3 3 3 3 3 kubernetes.io/os=linux 15h
kube-system csi-smb-node-win 2 2 2 2 2 kubernetes.io/os=windows 15h

Just like this csi-smb-node-win DaemonSet where there are 2 pods on windows.

I donā€™t see it for the calico-nodes on windows.

My guess is that it should have the selector kubernetes.io/os=windows for calico-node DaemonSet.

Fyi, iā€™ve never tried kubernetes on windows at all tho, but just tryin to help. :blush:

Hi, Does anyone know where are the images stored in the node or cluster? In my windows node, I tried to find it by tying docker image ls or ctr image ls; none of them can find any; also in the Linux node, please? Because I tried to delete some images but in vain. Many thanks!

27

Try with microk8s ctr images list

28

Thanks for your reply always. I saw some daemonset images in the Linux nodes but I canā€™t find any in the windows nodesā€¦by trying both docker image ls or ctr image ls.

29

Iā€™ve not tried windows node at all, can you show all calico pods especially those on windows.

Is this article support k8s 1.25.0?

31

@bangzhuzhu I havenā€™t personally tested it on 1.25 but it is certainly intended and expected it should work

32

The download link to the script changed!
Wrong = https://docs.projectcalico.org/scripts/install-calico-windows.ps1

Correct = https://github.com/projectcalico/calico/releases/download/v3.25.0/install-calico-windows.ps1

Many thanks for this, I will update accordingly!

34

This documentation doesnā€™t appear to work anymore, due to a Calico issue. Windows quickstart results in failing kubelet Ā· Issue #7552 Ā· projectcalico/calico Ā· GitHub

The Calico documentation linked in the Install section also goes nowhere.

35

Thanks for reporting, I will check into it

This is giving error:

Kindl provide complete latest steps for adding windows node to linux master node

Hi @Karthik_Medam, looks like the Windows node is having trouble contact the Kubernetes API server. Can you share some more details here (or perhaps in a GitHub issue)?
